I recently upgraded to the Thermaltake GF1 1050W fully modular power supply, and I couldn't be happier with my decision. Right out of the box, the build quality of the cables is impressive; they feel durable and sturdy, which gives me confidence in their performance. The cable length is also excellent, allowing for a clean and tidy setup in my case without any awkward bends.Installation was a breeze. The fully modular design meant I only had to connect the cables I needed, which simplified the process significantly. Everything fit perfectly, and I appreciated how easy it was to route the cables for optimal airflow.While the aesthetics of the power supply aren't particularly eye-catching, this isn't a deal-breaker for me. In my application, performance is key, and the GF1 delivers that in spades. It runs quietly and efficiently, providing stable power for all my components.Overall, I highly recommend the Thermaltake GF1 1050W for anyone looking for a reliable, high-quality power supply that excels in functionality over flashy looks. Five stars all the way!

Good PSU, not noisy , and it worked perfectly fine with my mother board, compatible with MOBO Asus B350

Running an i7-12700KF and RTX 4070 Super with the Thermaltake GF1 850W—no issues at all. Super stable under load, dead silent most of the time, and the fully modular design made cable management easy. Build quality is solid.Great PSU for the price—definitely recommend for mid to high-end builds, I personally don't care about looks as psu is not visible in my case, PSU handles everything easily , No issues, It's one of the A tier psus, One of the best bangs for the buck.

First impressions were good. The third-party reviews compelled me to buy this psu for the good value. Performance so far has been good, and the provided cabling is sufficient for my multi-gpu server. The cables aren't going tk win any beauty contests, but not terrible and highly functional. However... even under no load (even without any gpu plugged in, igpu only) it periodically makes very concerning coil whine. It starts as a low raspy grumble and works its way up to a VERY loud whine and then suddenly stops in an instant, as if related to a inductor charge and discharge. But why would the inductor cycle like this under no load? And where is the sudden discharge going? Of the dozens of psu I have used between 2001 and present, this is the first time I've ever observed such a sound coming from psu. It is loud enough to hear in the next room over. It doesn't seem to be related to any fan activity. I don't think this is normal... might need to RMA because something has got to be out of spec.

It's August 2025 and I think I've had this for a year now and it works perfectly! I'm loving this and when I get back home I'll try and add some photos.

600 watt unit works great and powers everything I need. If I bought a new power supply today, I would go one size higher in power, say 750 and I would buy a modular unit so I could remove uneeded cables.

Great power supply that does its job and is a good value for your money. Unfortunately, this PSU isn’t ATX 3.0/3.1 and does not have 12VHPWR, which should be a standard in 2024 as many GPUs now use that connector. Another negative I noticed is with the fan. The fan in this PSU isn’t exactly the best and is audible when operating. If you turn on the fan-stop feature, the fan won’t spin during low load and will spin during high load, but the issue is that the fan curve is based on temperature and the fan will keep turning on and off even if the system is under low load. It’s honestly better to turn off the fan-stop setting because when the fan starts up, it is loud so I don’t recommend using this PSU with the setting enabled.
