I am sure you get this question all the time, but I am really unsure of which PSU I should go with. Here is my hardware list:

NZXT Lexa Case (3x120mm fans + 1x80mm fan)
AMD X2 4400+ (using stock heat sink and fan)
Asus A8N32-SLI Deluxe mobo
2x eVGA Geforce 7800GT 256mb SLI
2GB (2x 1GB) Corsair XMS 3200CSPRO (comes with heat sink)
2x WD 200GB 7200rpm 8MB Cache Raid 0

I don't know which PSU would be the best for my rig. I am looking at 2 PSU's:
Enermax Whisper 2 535w SLI Certified
Enermax Noisetaker 600w SLI Certified

For now, I won't be overclocking until I get more comfortable with the system.

Any advice would be appreciated........

hi Boyo
I would suggest the 600 or higher if they make one. As PSU's run most efficienttly at 30 -70% of capacity. Running over that can cause problems. You have some high users there and you can add 30 W for a CD plus some sound. My opinion is to go 650 + watts
btw they are nice units. other than that Mfr,I would also recommend Antec, Thermaltake or PC Power and cooling, not in any order.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook

Wow. 650w+.......Thanks for the info. I didn't realize I was low balling the PSU that badly.....Back to the drawing board and start reading all the reviews again........Building a system is not as easy as it sounds....Thanks again....
