Customer Ratings & Reviews

purchased this power supply for my gaming PC and it has exceeded my expectations. From the moment I installed it, everything has been running smoothly and consistently without any issues. The build quality feels solid and well-made, and the components seem high quality and durable. One of the things I appreciate most is how quiet it is, even during long gaming sessions and heavy use. The cables are sturdy and the installation process was straightforward and hassle-free. It provides stable power delivery and gives me peace of mind knowing my components are protected. After several weeks of daily use, the performance remains excellent. Overall, this power supply offers great value for the price, reliability, and efficiency. I would definitely recommend it to anyone looking for a dependable upgrade.

This power supply is a fantastic upgrade over my old one. I was worried about switching, but it's been incredibly stable and quiet. The 10-year warranty gives me so much peace of mind, knowing it's built to last. Seriously, I can't recommend this enough if you're looking for a reliable replacement. It's definitely money well spent!

Quiet and powerful!! This power supply will cover the strongest graphics card out right now and it will also do it without a fuss!

1200w is a bit overkill for most PC's, but the peace of mind knowing that I never have to worry about my PC having enough power, lifted a wait for my shoulders that I didn't know was there. It gives me the freedom to upgrade the rest of my PC in the future without worry. If you can afford it, I definitely recommend it.

Paid 174$ for it in July of 2024. Its now May 2025 and I haven't had a single issue with it. Been a great PSU for the price I paid. I use my computer a lot. Do a bunch of gaming. Its been perfect.

Great PSU for the price had exactly what I needed to power my 9700xt. It is fully modular which is an upgrade from my last power supply. It's quite I never really here it and I don't have it in the silent mode. Easy to install nothing special.

had to purchase because of the 50 series gpus new power requirements, thankfully psu itself is not too loud, cables are great quality and feel sturdy, plus them being modular is always a positive.- honestly feels like the perfect option for high end systems.

Working well in our gaming pc. needed the best power supply for the 5090 card that could handle the power. new gpu power pin cable was a requirement, always happy with Thermaltake. for at $1900 GPU you don't cheap out with an unknown brand.

Due to the melting connector issues seen in some of the 5090 FE cards out there I decided to switch from the included 12vhpwr cord to the included 4x8pin adapter that came with my GPU. Unfortunately, there are only 5 PCIE PSU slots when I needed 5. For the price this is an excellent PSU and I won't deduct stars because of something external that doesn't really detract from the quality of this PSU. Just keep in mind the total cords your GPU might need.

Great supply, easy install, neat cabling, very compact

Excellent power supply, stable power. Excellent cable selection, fully modular and very quiet. Has the ATX 3.1 and 12v connector for my 5090, seats well.

Honestly great power supply unit and at a great price.

Very impressed with the Thermaltake GF A3 1200W power supply. The compact size is the first thing I notice when opening the package compared to a Corsair HX1200W, build quality is also just as good. Power delivery has been doing great so far with a 12900K, MSI MPG 790 Carbon WiFi ii, Nvidia GeForce RTX 3080 Ti 12GB.

Whisper quiet, with absolutely no issues. the new GPU connector is also a huge plus and made a significant difference as far as cable management goes.

My first psu ive bought nd it was very eash and simple. Wires were not stiff and easy to manage . Perfect

I caught this thing on a sale. I’ve had absolutely no problems with it. It came with every cable you could imagine and then some amazing product amazing results 10 out of 10.

It was an easy installation. It stays cool. Performs well.
