Gets the Job Done
Nice power supply. Works well with my setup and will handle the RTX3080Ti I will be installing soon. Good value and good quality.

Mega Loud and Stress Inducing
Took me 3 months before I realized THIS is the reason my PC sounds like it's taking flight every time I boot up a game. But worst of all, the fan speeds up randomly every 30 seconds while idol instead of staying at a consistent speed. This is a product that no-one should buy.

What happened to Thermaltake quality?
I've been building my own PC for over 20 years and this is hands down the worst PSU I've ever owned. Blew after 4 months. Hoping and praying it did not take anything with it. When it was working I would get audio pops every so often, most likely from unstable voltage. My PC under full load would use around 650W so not even close to the 1000W ceiling. Never buying a thermaltake PSU again. Update: It fried all my SSD's on SATA, hooray! DO NOT BUY NO MATTER HOW CHEAP IT IS!
