  • Thermaltake makes a great product that they stand behind.
Style: 80+ Gold (ATX 3.0) Size: 850W
When it worked it was great. I only had it for a short time before it started to go out, but I got in touch with Thermaltake and had a return authorization within 2 days. My replacement is already on its way.

  • solid purchase
Style: 80+ Gold (ATX 3.0) Size: 850W
upgrade for son's PC was necessary when he got the 4070 super. his old PC didn't have a 12 pin and I don't trust the adapters. installed easy and worked perfectly right out of the box. excellent price point if you don't have to have a modular PS.

  • Plenty of power for most systems
Style: 80+ Gold (ATX 3.0) Size: 850W
Plenty of power more than enough for most systems. I have an AMD ryzen 7 5800x, Nvidia Geforce RTX 5060ti, 32 GB or Ram and an older motherboard. B450M-G Galax Galaxy Microsystems motherboard. Cable management is perfect. Weight is pretty decent. Quality is gold and is really sturdy. Stability is fantastic. ... show more

  • DOA so cant say much on how it works
Style: 80+ Gold (ATX 3.0) Size: 850W
I cant say for sure if it was gonna be good or not as mine was defective/broken/busted. It was shipped in a bag not a box and the product box was bashed up pretty bad. So it was DOA. I will say we did put it all together and it was the hugest pain. I'd go with a module power supply ( which i ended up doing) this thing has soo many unless cords just all over the place. ... show more

  • Plenty of Power
Style: 80+ Gold (ATX 3.0) Size: 850W
With all the peripherals (dual Monitors, dual GPUs, etc) desktop PCs need a lot of power. This PS should meet most user's needs. This is the second unit I've purchased. I discovered (after purchasing this one) that the Power Supply Tester I was using was not reliable (Power Supply Tester IV, P/N X0013BGLUJ. It was returning faulty readings on the first PS I purchased (3.3v unstable, also warning beeps). But, when I used my multimeter and the pinout I found online, both Power Supplies tested good! 5-Stars. ... show more

  • Beefy, Nice looking PSU Beefy, Nice looking PSU
Style: 80+ Gold (ATX 3.0) Size: 850W
Some of the pins don't fastened as tightly as the unit I'm replacing. That said, it is working very well, and it looks nice inside my case. Pretty flexible cable management, normal size, and more importantly very quiet. Considering the price, the value definitely earns it 5 stars. I expect this unit to have a long lifespan. It seems really solid. One star removed for the aforementioned pins being looser than I like, and for the packaging being moderately dented. Still recommended. ... show more
