  • Reliable, Quiet, and Worth Every Penny
Size: 850W Pattern: Gold
I’ve been using this power supply for a bit now, and it’s been rock solid. Installation was smooth thanks to the fully modular design—no cable spaghetti to wrestle with, which already makes it feel like a win right out of the box Performance-wise, it’s been consistent and quiet. Even under heavier loads, it doesn’t sound like it’s trying to take off, which is a huge plus if you care about a peaceful setup. The build quality feels premium, and everything from the cables to the unit itself gives off that this isn’t going to fail you at the worst possible moment vibe. If you’re putting together a system and want something dependable without second-guessing your choice later, this is a safe bet. No drama, no surprises—just clean, steady power doing its job. ... show more

  • Solid choice for your needs!
Size: 850W Pattern: Gold
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! ... show more

  • I Trust Thermaltake
Size: 850W Pattern: Gold
I'm an old time PC builder and have been building PCs my entire adult life. When it comes to PSUs, I just go with Thermaltake. Sure there are other quality brands out there, but it's just one of those decisions I make for myself. Always reliable, great instructions, plenty of modular cables to select the ones you need (while not needing to deal with those you don't), runs completely silent unless you decide to turn that feature off (easy external switch on PSU to do so). I wish it came in white; but that's not a reason to deduct a star from this excellent PSU. I always go a bit more on the PSU watts then I need (could have settled for a 650-750W PSU), but it's just something I don't cheap out on. ... show more

  • Dead On Arrival
Size: 850W Pattern: Gold
The power supply arrived dead on arrival. I didn't have a GPU to finish my build initially, but once the card arrived yesterday, I tried to power everything up and nothing happened. I even tested it with a dedicated PSU tester, and it won't start at all. Very disappointed.

  • Modular and simple
Size: 850W Pattern: Gold
Exactly what I needed. My previous PSU had a surge and actually burnt out a fan cable, melted it to slag. This was a breeze to put together with some basic knowledge and ability to watch YouTube instructions
