Will my PSU be enough?

[jtwang05]

I'm currently upgrading my computer to a C2D E6600, Asus P5W-DH Deluxe, Corsair XMS2 DDR2 800 2GB, eVGA 7950GT. I have an Antec True Blue 480W PSU at the moment. Would I be needing to upgrade my PSU for this new system?

Depends on how much 12v power it has and if it has a 24 pin ATX power connector.

Should be plenty of power. And if it only has a 20pin ATX connector then you can just use an adaptor (I think it's only 20pin) and make it 24pin for the mobo.

22A isn't great for 400+ watt PSU but it is enough. However nothing there states what ATX revision it conforms to, I'm assuming it's and older 1.3 version unit which would mean a 20 pin connector and not a good choice for your upgrade.
