Modular, silent, enough power to get everything working. Paired with a 9070xt which prefers two dedicated PCI power connectors this was the best choice. Highly recommend, you don't need big bucks for a PSU when this is out there.

This is a great PSU. It was easy to install and everything was labeled and it comes with Velcro for cable management. I got extra Velcro cable management cables without realizing it came with its own. It fits perfectly in my matx Case. I liked at the specs and it was perfect. Everything connects easy and it has a fail safe if everything is not connected correctly it will not turn on until you reseat the connector properly. That is a nice feature so you won't have any melting issues. I will buy this brand again for my next build. It is nice and it goes well in my all white case. I have a checke
I thought this power supply was a great deal and got it 6 months ago. It is pretty quiet, and I like that it has eco mode. After half a year, one morning, I went to wake up my pc and it completely shut down and would not start. I had an old power supply from 15 years ago that I swapped out and everything works fine. These things do happen with pc parts, so I figured that it is at least under warranty and I can get a replacement. Unofrtunately, this is were it has been an absolute nightmare. It has been a week now since I contacted the manufacturer and they are making me essentially troubleshoo
excellent Product.Comes fully packaged with extra cords to fit anything on the market with handy bag to keep the extra cords.powers my rog strix b650 a wifi 2 with ryzen 9 9900x and 16 gig gskill ram at 6000 and msi 3060 vid card witho9ut any issues.excellent product for the money
UPDATE: 2/23/26. Still working beautifully, have my pc overclocked and the temp on psu has been great also fans super quiet. the voltage on 12vhpwr/5v/3v has been great and spot on. whole pc pulls around 600 watts. will be a year of having the psu in july.loving it so far, i have it in my pc with a 12900kf and a 5070 and has been working perfectly so far. i even have my 12900kf overclocked pulling in 300 watts and with the 5070 pulling in around 275 watts on full load. i also love that every cable came with velcro tabs and the cables themselves are a little stiff but i hear thats supposed to b
At first when I put it into my PC build, the Power supply kept shutting down as soon as you powered it up. The troubleshooting showed that the supply was functional. What I found out eventually was the GPU was bad, causing the PSU to fail to start. Replaced the GPU and now the PSU powers up. But in the process read some test results from outside companies which found that the protection circuits and components may not be the best. My build is working now. The cables provided were of decent lengths, the unit is very quiet while running and it fit very into my case.
Works and looks great
The power supply comes with 2 PCIe 5.1 display card adaptors which may be useful for new power hungry display cards. The power supply is relatively lighter when holding on the hand. The cables looks relatively narrower than those I used before. The cable coating is nylon feel which is very nice. However I do not know if this is good or bad for slimmer cables: on the positive side easier cable management, on the negative side, the cables may be undersized.Overall I am still very satisfied with this power supply especially the built quality.
