So due to a delay in shipping, all of my new parts except for the PSU have arrived. New motherboard is an EpoX 9NPA+ Ultra, with a 24pin connector. I have my old PSU, which is a 350w (antec or enermax, not sure but one of those) from a few years back, I'm pretty sure it's a 20pin. Can I use this old PSU for the weekend, to get the computer up and running? I don't want to spend money on an adapter for 2 days (don't know where I would get one anyway), but i'd really like to get this machine up and running. Will it work?
