Got Enough Juice????

[Caravan19]

I'm currently waiting for my second Evga 7800 GTX KO Acs3 to run in SLI. I currently have an Antec NeoPower 480ATX 12v v.2.0. Do I need to upgrade.....How much Would I need?

AMD Dual Core 4400+
2 GB ram
2 37 GB Raptors on Raid 0
1 Sony DVD Dru-810a
1 WD 120GB JB HD

As always your thoughts and comments are greatly appreciated!!!

I don't think you have enough for sli. You can tell when the frame rates drop. evga recommends 450 Watt for a SINGLE card. Plus the review above doesn't sound good. BTW, overclocking requires more power than stock.

Minimum of a 450 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 18 Amp Amps.)
