This power supply is a monster!!
Style: Gold 850 V3
They had a prebuilt gaming PC that I bought from cyber power. After about five months of owning it, I went to start up one day, and I had zero power. There was no power to the motherboard, no lights would come on, no movement from any of the fans, nothing at all. I went ahead and ordered this power supply to replace the one that came with my PC. It was super easy to route the cables from the motherboard to the backside so that I could keep everything neat and tucked away. The best part about this power supply is that you only have to use the wires that you need, so you don’t have a giant bulk of wire with connections that you don’t even use. The power is super stable and it is powering not only my computer, but my monster GPU, which is an RTX 5060 TI I highly, highly recommend this product. Cooler master has been around for a long time, and I have no doubt in my mind that this thing will continue to power, my monster gaming rig without any issues whatsoever. ... show more

Cooler Master MWE Gold 850 V3
Style: Gold 850 V3
This is a decent power supply for a new case that has a lot of fans for cooling. At first all the different power cables were confusing but they got sorted out and plugged into the sockets. I decided to put all the cables on before installing the PS because there just isn't room to do that when there's a warning about getting each cable exactly connected to the PS to avoid issues with overheating or failure. That went well, and then pushing all the cables in to the case first, the included screws attached it to the back in a perfect fit. The Cooler Master MWE Gold 850 V3 features zero rotation until the PS reaches a certain level of current or temperature to save energy, and has a 10 year warranty. The cooling fan is very quiet with special grooved fan blades and seems like a very good choice for this case which is one of those new modern types made of mostly mesh screens that promise super cooling. A quick and easy installation. ... show more

This power supply is fantastic
Style: Gold 850 V3
I've been using this for a while now, and it's been working perfectly. I'm running two GPUs simultaneously, so it definitely has enough power. Installation was easy, and it came with plenty of long wires to choose from.

Dead After 5 Days – Not What I Expected from Cooler Master
Style: Gold 850 V3
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. ... show more

Great power supply with really good lower power idle efficiency
Style: Gold 850 V3
Great power supply. I'm using it in a home server and it dropped my idle power with 5 watts.
