Hi,

Building a DOS retro PC and it’s been a minute since I’ve messed with computer hardware. I purchased two retro cases and they have two different power supplies (pictured). I was just wondering if both PSU’s will be fine to hookup to my motherboard (QDI v4p895grn)? They seem to have different output amps and I have no idea if that matters? I don’t want to fry my board. The DTK PSU has a switch to toggle between 115V and 230V. The other PSU has no such switch. I live in the United States.

Thanks for any help!

The DTK should be the better of the two, but ypu should pop them open and take pics then dump them on the big PSU thread to get some feedback. "A Tale of Two PSU's" iirc.

That is a good idea, but even if you don't go that far, you should at least check visually for bad/leaky/bulging capacitors and also if you see any of these RIFA capacitors, even if they look OK, replace them on sight . See https://www.eevblog.com/forum/chat/old-rifa-c … disaster-story/
