600 or 700W enough??

Current system:
- (4 gigs of) CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400C4


- AMD Athlon 64 X2 6400+ Windsor 3.2GHz Socket AM2 125W Dual-Core Processor Model ADX6400CZBOX

- GeForce 7300 GT - 450 MHz, 128-bit, 256 MB memory, PCI Express x16

And I just bought:
EVGA 512-P3-N866-TR GeForce 9600 GT Superclocked Edition 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card

Of course... I have a really old power supply, 430w and came with the case, aaaaaaand I can't even connect it... Doesn't have the connector. Bleh. Came home all excited too heh.

So... I need a new power supply. With the above specs, will 600W be enough, or do I need 700W?

Also, are there any power supplies you would recommend for the above system? (For around $125 or less)

More about 700w enough
  1. 550 watt is plenty for your system, and beyond.

  2. Oh...600W is more than enuf for tat setup...

    Best option and will be more than enuf even when u add another 9600GT...in SLI...

    If SLI is nt ur plan then this power supply is more than enuf...

  3. Wow, thanks guys. Didn't realize that it wasn't that much power usage. So 600-700+ is only for like, SLI or Crossfire setups? (Wondering about the future viability of whatever power supply I get)
  4. Well thinking of future viablity...then hw abt tis PSU :P ???

    Can easily hangle dual 9800GTX

    But sure is a ovrekill for ur current system....
  5. But it takes 1.21 gigwatts to power the flux capacitor. Actually a good place to look is in your motherboard manual to see what the manufacter suggests or requires for your board.
  6. Your current system would be just fine with an Antec Earthwatts 430. If you think you might want to SLI another 9600GT in the future, an Earthwatts 650 would be good. As long as the quality is there (Antec, Corsair, PC Power & Cooling, maybe OCZ), you won't need more than 650W for SLI.
