I have a raidmax 450W with 21 amps on the +12 volt. Will this be enough to power any of the graphics card listed above?
I am not planning to overclock or anything.
If this psu isnt strong enough what would be cheapest power supply that i would need to run it?
note: I recently had an 8800gts that ran well with this psu, but I discovered from some post that an 8800gts require more watts but the cards posted above requires less but need more amps? Why?
You could run the 4670 or the 5670 off that PSU, but not the 5750. The 5750 requires a 6 pin PCI-E power connector which the Raidmax on Newegg lacks. (Assuming your 450W Raidmax is the same as the newegg model). Also, I wouldn't trust any PSU that is available for $14.95 after mir. to power any decent graphics card and CPU.
