My need for this card came about because I finally bought a current GPU that was near the top tier. Previously I had only bought current mid-tier GPUs (3060ti, RX6800) or top tier cards that were 4-years old. All my previous power supplies only had a single PCIe power line that had 2 daisy chains off of it. This worked great - even if I had multiple GPUs. Upon upgrading to a top tier GPU, the computer would hard crash during GPU intensive tasks - meaning it would be unresponsive to power or reset and could only be restarted by cutting off the power at the wall, then turning it back on. It did sound like a PS issue. At first, I went through my current power supplies - going from 500W to 750W to 1200W. But all the same thing. Then I read on the internet that this is common with top tier current gen GPUs (RX7900, RTX4080 or better) when the GPU is being fed off of a single PCIe daisy chained line. All my PSU, including the 1200W only had a single PCIe line daisy chained into 2. I looked for a name brand PS and found this one. I ordered it the thursday before Easter and it arrived in 2-days as promised. Since it's a modular PS, it takes slightly more finesse than just a wired PSU. The connections need to be run to the mobo and devices first, then dangled where the PS will be mounted. Then after putting the PS into position (before screwing it in), the cables needed to be hooked to the PSU, then the PSU screwed in. So far so good. No crashes yet. It's also quieter than all the ones it replaced and they were all known name brands - albeit all at least 2-years old. If it doesn't solve my problem, you can bet I'll be back with an update. Fingers crossed.

More than enough power for my Ryzen 7 9800X3D, 5070ti build. Anything above Gold is not worth the money in my opinion. Use that cash for other upgrades. Easy install, clean power, excellent PSU.

Bought this PSU (Cooler Master MWE Gold 850 V3 ATX 3.1) expecting quality and reliability, especially at this price point. Installed it in a new build, and everything worked perfectly… for five days. Then out of nowhere, it completely died. No power to the system, no fan movement, nothing. Swapped in a different PSU and everything else worked fine, so it's definitely the unit. Very disappointed, especially from a brand like Cooler Master. I understand failures can happen, but five days is unacceptable for a brand-new product. Now I’m dealing with the hassle of returns and a dead system in the meantime. Not sure if I just got a bad unit, but based on my experience, I can’t recommend this model. Spend your money elsewhere unless you’re okay gambling with your build.
