Yep. I'm currently using a 400W power supply from Sparkle in my system, and it runs just peachy.

Your PSU should be more than enough.

ok, it has a 20a 12v rail and it has one 20-pin ATX Power Supply Connector and one 4-pin ATX 12V connector and a AUX connector, isn't my new mobo, a evga 680i going to need a 24pin and 8 pin connector?

Yeah, I would say you should upgrade your PSU. You're going to want an ATX2.0+ powersupply for an ATX2.0+ motherboard.

I had an Enermax NoiseTaker 425W PSU (ATX1.3) and when I got my SLI board, I bought an ATX2.0 PSU as soon as I could. It's not a good idea to run newer tech hardware on older PSUs. Those components are designed to the ATX2.0 specifications for a reason.

Yep depending on the motherboard you will need a 8 pin connection for it. But that is not the case with all motherboards you have to check the specific model.

But yes that power supply has a high quality 12 volt rail and should be great for you.

Download the motherboard manual or contact EVGA for specific information about the backwards compatibility of power supply connectors for that particular motherboard. Whether or not a ATX v2.0 motherboard is compatible with a ATX v1.3 power supply depends on the specific motherboard design.
