Works great, runs quiet! Been using this PSU a couple of months now, no problems at all.

I picked this up for a new build with a high-end GPU, and it’s been flawless so far. The modular cables are a huge win—super easy to manage and they look great with that dragon-patterned design. I especially appreciate the 12V-2x6 cable with the yellow connector—it makes it obvious when it’s properly seated, which is a nice touch. The RGB fan is surprisingly quiet, even under load, and the lighting adds a subtle flair without being over the top. I also like knowing it’s ATX 3.1 and PCIe 5.1 compliant, so it’s future-proof for upcoming upgrades. Build quality feels premium, and the Japanese capacitors give me confidence it’ll last. Overall, it’s a solid power supply that delivers on both performance and aesthetics. Would definitely recommend for anyone doing a serious build.

I’ve been very happy with this power supply so far. The Autac 850W PSU works exactly as described and was easy to install thanks to the fully modular design. Cable management was straightforward, and the included 12V-2x6 cable made it a good fit for newer GPUs. The unit runs quietly, even under load, and the RGB fan looks great without being over the top. Build quality feels solid, and the 80+ Gold efficiency gives peace of mind for power stability. No issues at all since installation. Overall, great value for the price and I’m very satisfied with this purchase. Would definitely recommend.

I'm running this power supply on a new build I made and it's working great. Power supplies are one of those things you don't think about much, as long as they work. It handles a Ryzen 7 9800X3D and Nvidia RTX 5070 fine. It's actually more power than I need, but it's always good to have some headroom for when I eventually upgrade. In the long run, buying a gold rated and more efficient power supply is cheaper than buying a wasteful power supply you'll probably end up replacing anyways. It's quiet too. I don't notice its fan, at least not over the 5070's fan lol.

My son finally finished building his pc and the power supply was bad. The PC was not working. We had it looked at by a professional and they explained this power supply was the issue. So not worth the money and unfortunately could not return since it has been over 30 days of purchase. Do not waste your money!!!
