I'm guessing you have a Micro ATX case with a tiny little SFX power supply. You can get a replacement Fortron power supply (200W rating, a bit higher peak) from Newegg, and it *should* support those parts without problems. Your current power supply *shouldn't*, but who knows for sure until you test it!
