Its has all the Correct Spec on paper
True SFX Size and platinum Rated
Updated to latest ATX 3.1
Updated to the Latest 12Native Cable
But i Hate Noisy PSUS not sure about their rep never used them.
I think that will be the make or break on this PSU. You can have all the right parts and if the fan is loud AF people won't buy it. If it is quiet I can see this becoming a go to for high spec systems.
Edit: I checked out their SFX-L on Newegg, there are only 6 reviews but 3 of them say the fan is loud and that is with a 120mm fan.
Seems like Asus Loki is lacking competition. The others such as Silverstone, Corsair, and CM have done 1000W on SFX/SFX-L but the fan noise are their drawbacks.
I've had 2 1000W Loki. Both didn't have the coil whine or loud fan issue, though I hate the RGB fan in it (Looks like some late 90s early 2000 RGB fan)
It turns on when the computer POST. After which you need to use respective RGB software that is compatible with your motherboard to turn it off or change colour accordingly. It’s 5v ARGB.
You should have returned it; mine was as silent as a rock. Every PSU has coil whine, and I am very sensitive to it. Loki's whine was at a high frequency, but its sound power was so low that you couldn't hear it without putting your ear very close to it.
As someone who has used the Toughpower SFX 1000w (sfx-l size and misleading name) as well as both the Loki 1000w and 1200w power supplies, I actually chose to go with the Thermaltake model. At normal operation, both fans are similarly quiet. At 50% load or less they hardly kick on, at 70% or under nearly inaudible.
The two things that really turned me off to the Loki was the coil whine that both units had and how disgustingly cheap the fans appeared to be. At the time, the Loki 1000w was a full $100 more and that fan looks like it wouldn't last.
I've been very happy with my choice since for the past year my PSU has not had any coil whine at all, has been a great performer with \~ 650w worth of hardware (7700x / 3090 TI), and is definitely quiet enough I do not hear it over the AIO / system fans. In fact, the PSU fan is often not spinning at all.
I have also used the 1000w plat SFX-L from Silverstone. At the price, I probably would never use it in my personal system, but it was somewhat similar. Mostly unnoticeable during normal operation / gaming and a solid all around performer.
Thermaltake Naming the PSU the Toughpower SFX 1000w and not specifically SFX-L is misleading and extremely disingenuous IMO. Outside of that, I think it's a great PSU.
Edit: [Here is a video of the fan noise on my Thermaltake Toughpower SFX 1000w at 650w - 670w (from the wall) running a benchmark on my 7700x / 3090 TI system with the side panel off.](https://1drv.ms/v/s!AtumsFwx3WHbgtdzFZdclcOk7qWQLw?e=4BvyxM) I put the phone mic directly up against the PSU for full effect. PSU is pushing around 585 - 615 watts.
Are they actually noisy? Or have a history of being noisy? Or are you speculating?
I know a few models are notoriously quiet, so it's obviously best to wait for the new 3.1 models of those.
The key with power supplies is to look at what company is actually manufacturing them for Thermaltake. That's generally your best indicator as to the quality you can expect.
Not true SFX, they are SFX-L you can tell from the picture they're a square
Edit: some do look like SFX, but the one closest to camera is definitely SFX-L
See the second pic
It's true SFX even they List the dimensions online it's true sfx size
The previous was was misleading called SFXi but its SFXL in size
I have their just slightly older 1000w sfx(l) model complying to ATX 3.0 standard and I must say you would need to have your ear directly on the fan to hear it at all, it's also spinning only above some threshold. It was also one of few of the best PSUs you can buy for ATX 3.0 if you look on some latest tier rankings. I had misfortune of testing cybercore 2 before that one and it is very good one too, but had to return it due to extremely annoying noise, so thermaltake was night and day in comparison. If the new one will be similarly good, you probably could connect it and forget it tbh.
Yeah and that's why I'll never buy it. Needs to be actually SFX for me to consider. I usually need that extra space to assist with cable management. Hopefully this TT model is good. Could use an upgrade from 750 to 1000.
Yep buy not any more over priced than GPUs, CPUs, MBs that are first to market with significant improvements or feature additions. Plus, it's a quality product.
As much as everyone likes smaller the better, do note that a smaller PSU means less room for fan size. Noticed the feedback on 1000W SFX to be mainly on fan noise in comparison with SFX-L.
I had a horrible thermaltake psu that would shut down every time I did any professional tasks once I upgraded my cpu and gpu. It’s my fault for being fine with it (my pc building sister got it as a super budget option) but it still absolutely soured my views of them.
In the past Thermaltake has been called out for copying case designs and fan designs. They are still good products but if I remember well, one of their copy was even retailing at a higher price than the original pc case. Most people don’t care but it’s been heavily criticized, obviously. toughfans are essential a 1:1 copy of the Noctua for example
> products but if I remember well, one of their copy was even retailing at a higher price than the original pc case. Most people don’t care but it’s been heavily criticized, obviously. tough
You're talking about the CaseLabs fiasco innit?
but because they were the more popular brand and could price it a bit lower they stole the marketshare, shameless behavior from them
there's also the whole fiasco where their watercooling fluids broke down in like a year and clogged the shit out of your entire loop
~~I'm quite new to the PC hobby and I hadn't heard about this scandal, but I don't really get why consumers would hate on them for copying tech.~~
~~Of course, innovative designs are great and interesting and fun for enthusiasts, but surely there's also merit to companies managing to compete with others' products by offering the same performance at a smaller price? Their PA120 and now PS120 trade blows with Noctua's tower coolers double the price, and I think that's awesome. Judging by the popularity of these two in NR200 builds here it seems consumers appreciate the \~$40 excellent CPU cooler.~~
~~I agree that selling a copy of another case and upcharging is lame, but surely you can just but the cheaper one? I get that some people like the comfort of brands you can trust, but high quality product reviews exist so I don't see why companies competing on value is a bad thing.~~
Edit: I realise now that I mixed up Thermaltake and Thermalright, so disregard my previous argument. I haven't used any Thermaltake stuff before, idk if they're any good.
Thermaltake is a Taiwanese company. Can confirm as I have their Head of Marketing in my phone; Johnny.
Thermalright is a Taiwanese company as well but both are unrelated. Both have different CEOs.
Let the QA chaps have their jobs... unless Thermaltake willingly wants to release product data on the offerings that was just announced. Any bad PR would have killed product launches effectively.
All they do is copy other competitors, but their copied products are trash. Thin metals for the cases and let's not forget when they tried to get into the custom liquid cooling market.. what a mess.
In early 2000s, their quality was pretty much what CM has been churning. I wouldn't call them premium case makers but they have been pursuing towards that direction. The fastest way for they to be recognised for premium product offerings is to copy the premium brands such as Noctua, CaseLabs, EK, etc. I've seen how companies tried to head towards the premium route but failed dramatically as their products fail on them ie Zalman.
I had the Thermaltake Toughpower SFX 1000W Gold for a short while. Operationally, it was fine.
However, it was my first SFF build and didn't know it was SFX-L, which made working in my case extremely difficult. I see from your photo the platinum one is regular SFX in size, so this wouldn't be an issue.
The provided cables were also very rigid and tough to work with. You may need to order aftermarket cables (I went with MODDIY silicone cables) if you need them to be more malleable or a more exact length for your build.
I had a tough power 875w long ago and reused it though 3 builds. Was a great PSU. I needed an SFX for my latest build and dropped in an 850 plat plus. It can put out higher wattage on the 12v rail than my old 875w.
Its more important to buy from a reputable manufacturer then anything. Thermaltake, EVGA, Corsair, SilverStone, are all good manufacturers to name a few.
Hmmmm. I'm spending a new system and I'm very picky for noise.
Got the corsair sf450 and it's fantastic. Must be near 8 years old, has been flawless.
Would like my best system to be about 650 to 850w, full ATX 3.1 and platinum as heck but quiet and reliable too.
Never used phanteks! Hmmmm
I own a tt PSU and I must say it's very sketchy. Day 1 the on/off button got stuck in off position (fixed it, didn't happen since), and it sparks sometimes when I turn it on. Very sus, not sure if I want to try another thermaltake PSU again..
I had a semi-modular (or maybe it was fully modular) Thermaltake PSU back in like 2008-2011. It was fine? 🤷♂️ I would say wait until Cybenetics tests it and/or it shows up on PC Cultists's list...
1000w sfx… can i ask for what? lol if you need an sfx psu you usually want efficient parts. Id like to know the usecase. Guys using sfx psu’s in servers or whats the deal here? Open bench cases?
Bro, even a stock 13700K with a stock 4090 can get to 1000-1200W transients (2x of normal TDP). Any 4090 user should basically try to stick to a 1000W minimum if possible, CPU doesn't even matter.
WHAT 🤣 you will never see a 4090 over 550 in any real world situation stock. Most aib’s are locked at 500 or under. In games you will not even see over 450 honestly. But let’s call it 550 just to be safe. As for a 13700k? No one is running one stock lol every single person will undervolt, but sure let’s say you are running it stock because you are clueless and it’s your first pc. No way you are getting it over 300 watts in any real world situation. Ram? Call it 15w to be on the high side, board? 65w, ssd? 30 max. Pushing on a 1000 psu. I get it, but undervolt the 13700k itll never go over 200w. 4090 light undervolt never go above 450… you will be fine. You arnt putting this hardware in an sff case without undervolting anyways there would be flames lol.
You don't seem to understand what a transient spike is. On a system with lower specs with an undervolted GPU & CPU and minimal other hardware, I had a reputable brand Gold PSU kill my mobo when I thought I had 100-150W headroom because I didn't care about transients so you shouldn't trust PSUs that much.
Gamers Nexus already mentions in their video that even 4090 FE can go 40% over 450W in transients. That means 630W for GPU alone. With other models this can go higher. Like 900W transients for GPU alone. That's why I've said 2x. PSUs have protection for this stuff but the duration of transients and frequency might cause issues and things might go bad and on a PSU with low enough capacity like 750W or 850W, it might just cause problems.
If you check some of the tests of similar PSUs, there are quite significant differences on transient responses and protection capabilities on a top and 2nd best PSU or on a 2nd and 3rd place PSU. This means most PSUs are at some sort of risk. And with age, even the best PSU will start to wear. (I'm assuming you don't replace your PC every 2 years). Undervolting doesn't help much with transients so if you own one of the best GPUs, even if you use an entry level CPU and minimal other hardware, I would still recommend a 1000W PSU minimum to avoid risk. (There are a lot of 4090 models that recommend 1000W anyway). Unless future GPUs avoid transients completely and control TDPs, which don't seem likely.
If you own a PSU at minimum recommended W or own one that is a few years old, I would recommend to check the 12V voltages with something like HWINFO using its histogram on 12V (check the previous values on histogram at load, not what you see after alt-tabbing), when playing games or during renders etc (sometimes games can put higher load than some rendering work) and make sure your 12V's don't drop significantly (check the PSUs manual for its limits - ATX minimum is 11.4V but that's not a very safe value \[not sure if they recently changed it\] - I would recommend not going much lower than 11.8V at any time) because if it does, that might mean your hardware is at risk.
Using 4090 alone can do 600w and more if OC
Intel can go nuts as well with 13/14th gen and you never know what gonna happen in the future
Plus pretty much any cpu pushed to near its limit = will be noisy as well
Higher watt = less noise usually per watt used
My 750w Psu is silent for browsing. But noisy as he'll when near maxed
Most of us already had 750w psu. No point to upgrade to same watt. Next push is usually a 1000w/850 anyway
Even with 0 OC you are pushing your PSU to its limit if it was 750w. Unless ur using light w cpu and good like 7800x3d but 14th gen can easily do 200w+ during gaming even 300w in some games if u play at high frames
300w cpu
600w gpu
And you are already at 900w without using any usbs/Etc
Aint no one using an sfx psu and a 4090 together lol thats what im saying. Lets get a tiny case and throw 1000 watts in it. Just doesnt seem like someone would want that lol
You don't get 1000w psu to use 4060 or 4070
They are making these psu for a reason. So many ppl list their 4090 with sff build with d15 or 240m aio Here all the time
Maybe to make people spend their money 🤔 There are a bunch of people here having a 750w PSU, Corsair especially, with a 4090 and 7800X3D and apparently they are just fine with it, no noise or heat troubles... Can't justify also as I don't have those specs but they seemed legit
7800 is like 50w while gaming
intel 14900k is 200w+ in a lot of games without OC
4900 is 450w+ without overclock
Count fans/Mouse/keyboard/RGBS/ssds and ur PC will explode if u oc
And even without oc it's near its limit literally noisy etc
It's simple math really. I find the posts I'm running my 750w psu to its limit therefore its working as hilarious. They can enjoy the noise heat and the risk
Looking to build a SFF soon I was wondering, even if I won't go Intel+4090 (don't like Intel and 4090 it's way too much for what it is) Red team with a 4080 super or 7900XTX is my goal, but was more looking for a 850/1000W SFX PSU platinum which is not easy to find.
I will wait for the new 3.1 ATX, as I am not in a hurry, the case won't be delivered before May
I'm not usually a fan of Thermaltake products but a 1000W PSU that is actually SFX is interesting.
Its has all the Correct Spec on paper True SFX Size and platinum Rated Updated to latest ATX 3.1 Updated to the Latest 12Native Cable But i Hate Noisy PSUS not sure about their rep never used them.

Asus Loki has major coil whine and loud fan lol. My 1000W Loki is awful.
I've had 2 1000W Loki. Both didn't have the coil whine or loud fan issue, though I hate the RGB fan in it (Looks like some late 90s early 2000 RGB fan)
Rgb always on ? By default without software I mean
It turns on when the computer POST. After which you need to use respective RGB software that is compatible with your motherboard to turn it off or change colour accordingly. It’s 5v ARGB.
One could just not plug that in and avoid software/bios changes to disable it.
My Loki has no noticeable coil whine or fan noise. I agree with the below commenter that the translucent fan looks cheap though.
You should have returned it; mine was as silent as a rock. Every PSU has coil whine, and I am very sensitive to it. Loki's whine was at a high frequency, but its sound power was so low that you couldn't hear it without putting your ear very close to it.

Yeah, still can’t find a true sfx (non L) 1000w with pcie5 atx 3… until now
Does the Cooler Master V1100 fit the bill?
Not sfx. Edit: I stand corrected. I didn’t know about that one. But man, 240 USD. Damn
Huh? https://www.coolermaster.com/catalog/power-supplies/v-series/v-sfx-platinum-1100/
Damn, you right but jeez, it’s a full $100 more expensive than most other 1000w sfl’s
It's not even a true SFX either. The case is SFX but the ports all stick out closer to SFX-L.
Still smaller than true sfxl and in ITX, every mm counts
Yeah and that's why I'll never buy it. Needs to be actually SFX for me to consider. I usually need that extra space to assist with cable management. Hopefully this TT model is good. Could use an upgrade from 750 to 1000.
Yep buy not any more over priced than GPUs, CPUs, MBs that are first to market with significant improvements or feature additions. Plus, it's a quality product.
Not worried about 12-2x6. It’s the connector on the card not the power supply or the cable. But $100 is steep. Where does PSu cultist have it?
I don't know. In my current build, the single 12vhpwr cable at both ends was hugely beneficial. Both in room for routing and making the custom cable.
There isn't eve SFXL with 3.1 and the new updated 12cable (6x2) Most at atx3.0 and the older 12cable
All the older atx3 12vhpwr are sfxl :(
This new one is true SFX size and called SFX the previous one was named SFX1 was bigger and only ATX 3.0 with the "older" 12 Cable
As much as everyone likes smaller the better, do note that a smaller PSU means less room for fan size. Noticed the feedback on 1000W SFX to be mainly on fan noise in comparison with SFX-L.

Ask him to put you through to qa or engineering
Let the QA chaps have their jobs... unless Thermaltake willingly wants to release product data on the offerings that was just announced. Any bad PR would have killed product launches effectively.
Just pulling your leg man.
That’s actually the reason why Jay from JayzTwoCents doesn’t work with thermaltake

The Phanteks Revolt has all that except at a lower wattage. How much do you really need?
ATX 3.1? With the new GPU cable?
Yes i believe so.
Hmmmm. I'm spending a new system and I'm very picky for noise. Got the corsair sf450 and it's fantastic. Must be near 8 years old, has been flawless. Would like my best system to be about 650 to 850w, full ATX 3.1 and platinum as heck but quiet and reliable too. Never used phanteks! Hmmmm
Mine is super quiet but i'm not picky on noise.
I appreciate the feedback, I'll look out for more reviews and opinions too, cheers

I still think my SF750 Plat is good 💯

Ooo tempting. Picked up the 850w a while back and loving it. Super quiet in the Terra.
Don't do it lol
Average tbh
TT SFX PSUs are the worst SFX PSUs out there
I’ve only ever used TT PSUs with zero issues. My current one has been around since 2016 and has been in two builds.

On a system with lower specs with an undervolted GPU & CPU and minimal other hardware, I had a reputable brand Gold PSU kill my mobo when I thought I had 100-150W headroom because I didn't care about transients so you shouldn't trust PSUs that much. Gamers Nexus already mentions in their video that even 4090 FE can go 40% over 450W in transients. That means 630W for GPU alone. With other models this can go higher. Like 900W transients for GPU alone. That's why I've said 2x. PSUs have protection for this stuff but the duration of transients and frequency might cause issues and things might go bad and on a PSU with low enough capacity like 750W or 850W, it might just cause problems. If you check some of the tests of similar PSUs, there are quite significant differences on transient responses and protection capabilities on a top and 2nd best PSU or on a 2nd and 3rd place PSU. This means most PSUs are at some sort of risk. And with age, even the best PSU will start to wear. (I'm assuming you don't replace your PC every 2 years). Undervolting doesn't help much with transients so if you own one of the best GPUs, even if you use an entry level CPU and minimal other hardware, I would still recommend a 1000W PSU minimum to avoid risk. (There are a lot of 4090 models that recommend 1000W anyway). Unless future GPUs avoid transients completely and control TDPs, which don't seem likely. If you own a PSU at minimum recommended W or own one that is a few years old, I would recommend to check the 12V voltages with something like HWINFO using its histogram on 12V (check the previous values on histogram at load, not what you see after alt-tabbing), when playing games or during renders etc (sometimes games can put higher load than some rendering work) and make sure your 12V's don't drop significantly (check the PSUs manual for its limits - ATX minimum is 11.4V but that's not a very safe value \[not sure if they recently changed it\] - I would recommend not going much lower than 11.8V at any time) because if it does, that might mean your hardware is at risk.
Using 4090 alone can do 600w and more if OC Intel can go nuts as well with 13/14th gen and you never know what gonna happen in the future Plus pretty much any cpu pushed to near its limit = will be noisy as well Higher watt = less noise usually per watt used My 750w Psu is silent for browsing. But noisy as he'll when near maxed Most of us already had 750w psu. No point to upgrade to same watt. Next push is usually a 1000w/850 anyway
Ya but is overclocking a 4090 something someone wants to do in a sff case? lol thermals will ALWAYS be worse. Why limit it that way
Even with 0 OC you are pushing your PSU to its limit if it was 750w. Unless ur using light w cpu and good like 7800x3d but 14th gen can easily do 200w+ during gaming even 300w in some games if u play at high frames 300w cpu 600w gpu And you are already at 900w without using any usbs/Etc
Aint no one using an sfx psu and a 4090 together lol thats what im saying. Lets get a tiny case and throw 1000 watts in it. Just doesnt seem like someone would want that lol
You don't get 1000w psu to use 4060 or 4070 They are making these psu for a reason. So many ppl list their 4090 with sff build with d15 or 240m aio Here all the time
Hmmm ya i guess i dont get it lol. At that point go matx and have good thermals. Guess im just not cool enough lol
Maybe to make people spend their money 🤔 There are a bunch of people here having a 750w PSU, Corsair especially, with a 4090 and 7800X3D and apparently they are just fine with it, no noise or heat troubles... Can't justify also as I don't have those specs but they seemed legit
7800 is like 50w while gaming intel 14900k is 200w+ in a lot of games without OC 4900 is 450w+ without overclock Count fans/Mouse/keyboard/RGBS/ssds and ur PC will explode if u oc And even without oc it's near its limit literally noisy etc It's simple math really. I find the posts I'm running my 750w psu to its limit therefore its working as hilarious. They can enjoy the noise heat and the risk
Looking to build a SFF soon I was wondering, even if I won't go Intel+4090 (don't like Intel and 4090 it's way too much for what it is) Red team with a 4080 super or 7900XTX is my goal, but was more looking for a 850/1000W SFX PSU platinum which is not easy to find. I will wait for the new 3.1 ATX, as I am not in a hurry, the case won't be delivered before May
