Power supply from an old build of mine that wasn't used much. Wasn't under load often, and when it was, the load capped out at ~400W

Lost the extra cables, but I'm sure they can still be sourced. I'm just too lazy to get them.

Was known working, but haven't tested it in a while. Plugged it in with a jumper and it powered on, no magic smoke so assumed good? Would not recommend using it in a critical build, more of a hotswap backup/ test bench PSU
