    • It's a very good value, but cables not compatible with older Rosewill models
I bought two because they were on sale, but had to return them. My issue was that the connectors on PSU side are *mechanically* compatible (like the pattern of which pins are square vs tapered) but NOT *electrically* compatible to older Rosewill PSUs. I do custom cable sleeving, and felt that having a mix of 4 old Rosewill PSUs (3 Quark and 1 Tokamak) with these 2 new ones would lead to future confusion. One of the reasons I bought them, other than it being an excellent deal, was because after zooming-in, I noticed that the connectors physically match. But because they don't electrically match, I can't share cables between them which defeats the purpose and it's also dangerous to confuse them. That said, why the heck would Rosewill do such a dumb thing?! I'm guessing because they use a variety of suppliers over the years. ... show more

    • Does not provide second 4+4 CPU power connection for gaming MBs
Size: PMG650
Overall seems to be a good PSU, but as I was assembling it with MSI MPG Z590, I noticed there is no second 4+4 CPU cable, and 6+2 PCIe cannot be used instead. The rig does work with only one, but had I known it in advance, I'd buy something else with two connectors.

    • worked for several days
Size: PMG650
This PSU worked fine for several days and was pretty quiet, which I like. The cables included are a little short and that interfered with me keeping things as tidy as I'd like - not enough slack to reach all tie-downs, but I was able to make them work. Yesterday I went to turn on, and nothing happened - PSU is unresponsive. I put the psu in a second computer and it did not work there either - so I’m confident the PSU is bad, It is packaged nicely and was much quieter than the PSU it replaced. Wanted to swap out with a replacement but Amazon won't ship a replacement. Now I have to rebuy at a higher price which is I suppose why Amazon will not exchange. ... show more

    • Power Supply seems to have cooked my motherboard and I don't know what else
Sent the initial one that was damaged before shipping, and ordered one straight from newegg since it was almost $50 cheaper. Bad idea, replaced the power supply in my computer and it never got to the post screen. Put the old power supply back in and nothing powers on. So I get to probably buy at least an new motherboard and who knows what else. ... show more
