Almost 1 year of use.(I will update if something happens.)
So far so good, bought it on Dec 27, 2025. No problems and no noise. Got a rx 9060xt. The graphics card is rated for 150/160 wats so that’s probably why. But yeah no problems. Gives enough power and the cables are easy to install. I only had trouble with the motherboard haha, it’s just difficult to remove the cables once they are plugged in.

Quiet but smelly?
My computer was shutting down randomly a few months after buying a new graphics card. The PSU was 11 yrs old, so although it was 650w and the minimum suggestion from AMD, I didn't feel it was quite right. I also needed extension/splitter cables to fit the plugs on the new graphics card since the old PSU didn't have 16 pins cords... not a good look. This came with more plugs than I needed (hallelujah for modular designs), and fit my 6700XT perfectly. I used both of the 8pin cables and plugged them both into the 2 PCIE slots on the PSU, instead of using just one wire with the additional 8-pin attachment. (see attached). After giving up on my defective RAM sticks (again), I've since had no BSOD error, or random system crashes / freezes that lose all my hard work throughout the day. The crashes I faced before were almost certainly the fault of my old, failing / struggling PSU, but if I run into them again I'll update this review. Even if I face those issues again, it wouldn't be the fault of this product, but I did want to make note of it because system crashes can be linked to failing PSU's and people need to be assured of that when considering applicable remedies; for me this was a purchase out of necessity, not comfort / preference. The PSU itself is also ultra quiet. For the first couple days, I smelled a factory-like scent. It was a little strong, but it has been a few days now and has gone away. I always thought my graphics card / HDD was making noise--it turns out it was my old PSU, because now I hear ALMOST NOTHING from my tower, and certainly nothing from the PSU. This is a great, great buy.

All you need
Upgraded pc from 2070super with a 600watt psu and was getting a 5070 . Needed a psu with 12vhpwr native connectors and this had it . Very happy with my purchase . Now I’m running the 5070 and ryzen 5 7600x and both with a slight OC . No issues yet , about 2 months in . No fan noise . Very high quality cables . Everything connected properly and it has up to date features . Looks good too .

One Year Later, still going strong
It’s been over a year of use and I have had no problems with this PSU. Bought this in March of 2025 and it’s still running strong today. My PC specs are 9070XT GPU, Ryzen 7 9700X CPU, AIO cooling, and everything runs fine. Haven’t heard any “noise”. Really quiet even when the fan does turn on you can barely hear it. All cables were included and provided sufficient power to my PC build.
