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.

I got this when it was on sale 850 V2 for $70. It was a very good deal. I really appreciate this seller! I use this with a power hungry 7900X. The PSU itself is not super quiet. It's ok. My last PSU was able to completely turn off fan, this one is always running at like 500-700rpm or something. But at this price, and 850W (849 of which are available on the 12V rail!). Also, it has only 2 EPS connectors, but you can always buy your own later. At my purchase price, it is great value for money. Product came sealed, but in its brand packaging (no outer Amazon box, which is good for the environment, I guess) Update: 1 month later, I still have no problems. I notice the fan is kind of strange. It's not a smooth sound, it's kind of an warbling, like the blade or bearings are unbalanced. It was like this from the start, and has not changed. Also, the fan is supposed to be sucking from the top and blowing out the rear of the case, but if you put your hand over it you can feel it blowing out the top. Very peculiar. It's like the fan "sucks" literally/figuratively. Still, this was an amazing deal, if this lasts 5 years, it gets ⭐️⭐️⭐️⭐️⭐️ from me.

Nope. Never touching CoolerMaster again. Bought in November, died in June, it is currently July 25th and I still have no RMA. I finally got a first response on 7/19, three weeks after my initial request. Sorry, send us your info and we'll... I have no idea what. Another week later, nothing. Maybe a replacement is already on the way, but there is no way a person isn't forced to buy another power supply when this is the timeline. At this point, I'd rather this review wards one person away from CM than I get my warranty. There is a reason I left the PC game years ago, thank you CM for quickly pulling an Asus and reminding me. To be clear, this was a five star 'worked as expected' review. I did not change it when the PSU failed. Stuff happens, things fail, I'm fine with that. I even bought the replacement PSU of my own accord without being grumpy about it because PC warranty is what it is. But if I had waited, what is now, a couple days shy of a month with absolutely zero movement except for what amounted to an acknowledgment email, I would have waited a month for nothing. Unacceptable. Edit, 7/31 and still no communication. Edit edit, i bumped my first reply on 8/12 and 8/19 finally got an email saying their system blocked my first reply with the invoice and shipping info. I sent it again and they had the RMA to me within an hour. Again, their first response took almost a month just for another month to pass before they tell me the dog ate their homework.
