Hi guys, I am sure there a few of the threads around, but I just have one quick question. I am building a new computer and I am curious if I have to buy a new PSU or if the one I have is good enough. New System Specs: AMD Athlon 64 4000+ ASUS 6800 GT (PCI-E) 2nd one later on. ASUS A8N-SLi Deluxe 2 GB Corsair XMS 3200 Sound Blaster Audigy 2 2x Western Digital 74 GB 10k Raptors 16x DVD 40x CD Reader 16x Dual Layer DVD Burner about 5 case fans My current Powersupply is the Enermax 470 watt Noisetaker. Should I invest into a 500 - 600 watt PSU? or should the one I have now do just fine?
