    • I'm impressed!
Style: RGB850-PRO
My old beloved Corsair850 blew in my old PC from a lighting storm, so I wasn't particularly looking forward to the cost of having to replace it. Came across this unit, read some reviews, and placed my order. First of all, I could care less about lights and stuff like that. Not my thing, but this was actually kind of cool and nifty. Unit installed like a charm, and once connected, everything worked perfectly and as it should. I was impressed the unit also came with a "dummy plug" for pre-testing the 24-pin connector. I had never seen that before. Changing colors is quite easy as well. There were PLENTY of cables for various connectivity options - whether you are using newer components or older 4-pin power cables. All in all, the unit is a great value for the money, and...it's QUIET!! No obtrusive fan noise! I would highly recommend this unit! ... show more

    • Many times thought it was bad but it wasn't
Style: RGB850-PRO
This has actually been working great for almost a year Had some issues with games shutting off or the computer randomly shutting off but found out it was a bios memory setting. This is working well now for over a month with no random shut downs. I'm a computer builder and didn't really trust an off brand but even though these are lightweight and the brand is not well known, I have to say I've been very impressed. My son recently upgraded to a Ryzen 7 and Nvidia RTX 3070 and it's been working great on ultra high settings for many GPU intensive games and there are no glitches. ... show more

Sat power arced and cable went bad. Burned up and destroyed the power connection to my SSD, probably the board (of the SSD) too. Prior to that it had served me well running for 2 years. Everything fit well and was relatively quiet. So you can understand my surprise when adding another SSD from my old machine caused an arc and tons of smoking. It's extra frustrating because drives aren't cheap these days and it killed one of them and now I'm out of commission on my research ... show more

    • Working great in my PC setup
Style: RGB850-PRO
Working Great in my AMD Ryzen 9 9950 x 3d PC I just built. Powering a Nvidia 5070 card, 4 ssds, 3 m.2 nvme ssds, liquid cooler , and 9 rgb fans with plenty of power to spare. Recommended. Can only see the rgb lights from the back as the case has black sides where the power supply is .
