Customer Ratings & Reviews

Currently powers my new pc setup without and issue. Running 7800x3d, 7900xtx, strimer cable, lcd cooler, secondary lcd and 12 rgb fans. No issues and hasnt had any power bottle neck at all. Quiet and efficient. Excellent power supply.

Great quality power supply. It's a thermaltake di i need to say more? Quality is outstanding.You do pay a little bit more, but it is so well worth it.Because, you know, you're getting a quality product. It's a module power supply, so you only need to use the cables that you need.So you don't have a bunch of extra wires hanging around. I know that's not the best quality picture in the world.That I provided, but there is a cover over the power supply.So I can only get a picture of the back, but you can see that i've got most of my cables being used.But I also have a monster system.

Super tiny super quiet! The Toughpower GF A3 1050W is Platinum certified by Cybenetics in efficiency, while in noise, it has a Cybenetics A- badge (25-30 dB[A]). It uses a 120mm sleeve bearing fan, while the 1200W model uses a fluid dynamic bearing fan. I am not sure why TT used different fans in these two models, but I don’t approve of the drop in the fan’s quality. There is a semi-passive operation available, which can be switched off if you want the fan to be in operation constantly, and the provided warranty is ten years long, so TT is confident of the PSU’s reliability through time.

Purchased a RX7700XT GPU and had a cheap 650w. Replaced it with this monster. Love thermaltake but the smart power PSU are garbage but tough power is much better and powers the card and have plenty of power for anything else I can think of.

Great product, excellent price, supports 12VHPWR, plenty of power for my i7-12700kf + RTX 5080 setup. Nice, classic looking black cords which is a style I like. Seems great b

The product being modular made it really easy to use and then install.

Perfect addition for my case. Runs my 9070xt and 12900k CPU without any issue whatsoever. Highly recommend this to anyone building a new PC.

Easy install haven’t had issues yet with the wattage atm with a 4090 and i9 works like a dream I’m sure with 5090 won’t be bad either

Honestly, it's a banger for the price! The only con I see is that the cables are stiff, but other than that, it's perfect.

Terrible. Power cable to the gpu melted on the psu side. Fried my 3080fe. Lasted less than a year.

Quiet and very efficient. The fully modular cables make the build clean, and the single 600W GPU cable makes cable management way easier. Solid, reliable PSU that feels built for high-end systems without any hassle.

The Thermaltake Toughpower GF A3 1050W has been a fantastic upgrade for my build. Installation was straightforward thanks to the fully modular design, and the cables feel sturdy and well‑made. My system runs quietly even under heavy load, and the PSU stays cool without ramping up fan noise. What really stands out is the ATX 3.0 and PCIe Gen 5 support. It gives me confidence that this unit will handle future GPU upgrades without any issues. Power delivery has been rock‑solid—no flickers, no instability, just clean, consistent performance. For the price, the quality and features are outstanding. Highly recommended for anyone building a high‑end or upgrade‑ready PC.

Works great plenty of power nice and quiet and easy to install and manage the cables

My PC was acting up and eventually shut off completely and I assumed it was a psu issue which it was. And this one was such an easy install and had plenty of clear instructions on how to get it in. Not to mention that extra 50 watts from 1000 does a lot and I love it for that

This was my first time buying and installing a new power supply outlet. Very simple instructions and very easy installation. Haven’t had any issues since i upgraded power supply.

Easy to install as they all are 4 screws. But this was nice due to not having to have a huge amount of wires that werent needes. Just plugged in the ones you need and leave the rest off. Kept the case clean and easily accessible. Came with a small bag for the extra wites that are in my parts box but i can add more if i need them later with ease. The fan on the unit actually disaptes the heat correctly and didnt mess with the ambient temp in my case. All in all couldnt ask for a better product.

Absolute POWERHOUSE for what it is! 1050W 80Gold rating in a small ATX form factor makes it a no-brainer for mid-size builds! Not to mention Thermaltake has a very good reputation lately!

Welp PC went down, needed one in a hurry and I've used a lot of PSU's so far in multiple builds. But this one by far was easy to figure out being modular and came with lots of cords plus some in case you need them. Cables weren't weird like some that I've used, everything looks fine even the main one being bent around the front to the Motherboard and the GPU plus cables are nice and straight as well instead of being all twisted weird. So all in all perfect and was a nice little upgrade from my little 700w that was in it. I'll def be looking into Thermaltake in the future for more parts.

So there are two different types of psu’s with this brand and I will say the ones that Best Buy carries is the one to want there are videos about the difference but I have been using this unit for a bit now and have no complaints the noise under gaming loads are quite and the power limits are great honestly I would recommend these units for gaming builds and for work builds because of the zero fan setting it feels stout and very quality made the cables could be a little more robust but honestly at the price point it’s all good I’m not concerned about about the 12vhw for Nvidia builds either

Worked perfectly on a ibuy intel 7 ultra tower with 5070 video card. the power supply came with cords to spare. smooth quiet operation and great replacement power supply better then what came with the tower by far.
