Well, I have a 750 watt power supply (that is a spare one) that I think would fit, this spare one has a 24 pin motherboard connecter, would I be able to use this in my computer with the converter you were talking about?
Its 500 watts I believe, but it doesn't have stickers that I know.
Do they all have stickers?
Pretty sure the unit is this one:
