Well the diablotek PSU would be a suitable replacement for that models power supply. It has a 20+4 main connector meaning it can either be a 20 pin or 24 pin (pretty much universal in todays standards). One thing to note tho, with the e machines and best-tec power supplies. When the PSU goes out in these E machines with best-tec PSU it normally takes out the motherboard as well. It might be you have a dead computer on your hands. I would try to borrow a power supply or yank one from a spare PC in your home to see if that is the case. I have in my garage rite now 4 dead E machines with best tec power supplies.
