    • 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.

    • 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

    • Quiet & Hard-working!
Style: Gold 850 V3
So far, this PSU has not failed me. I’ve had it running for a little over a month, and I never hear it, which is a great sign from a power supply. The moment you start noticing your PSU, you are probably in trouble haha.

Arrived DOA right out of the box. I noticed right away the box had been taped shut, and then after opening it found the Styrofoam top padding broken in two pieces, cables just shoved in there, and a broken connector clip laying in the box. I grew suspicious but gave the benefit of the doubt and installed it, only to discover it was indeed defective. I tested the same desktop with my 500 watt bench supply I use for testing motherboards and it powered up my pc. End result, faulty supply and a return has been initiated. If you read my review this far remember always trust your gut, if you receive something in similar condition like this, chances are its a reject. ... show more

    • Great power supply with really good lower power idle efficiency

Great power supply. I'm using it in a home server and it dropped my idle power with 5 watts.

    • Good psu right angled 12v high power a little inconvenient
Style: Gold 850 V3
Had this psu in my system roughly 6 months no issues cool and quiet, but one thing I think people should be aware of is the right angled 12v high power cable this is not compatible with all gpu’s that use this connection as there isn’t a standardized orientation of it so in my case I ended up having to use the pcie to 12v high power adapter provided with the graphics to be able to connect gpu to psu without bending the cables sharply at 180° back down to the bottom of the case. Now this is partially my fault for not looking closely at what I was buying but I doubt many others will either so if you see this just be aware. ... show more
