Video card/ power supply

Hi y'all. EVGA e-GeForce 8800 GTS Superclocked 640MB GDDR3 PCI Express video card recommends a minimum of 400 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 26 Amp Amps.)

My power supply is 400 Watts, but is the "recommended minimum" enough during gaming at full settings, and possibly multitasking also?

Thank you in advance.

  1. Well since the GTS uses about 110w peak, yes - recommendations are set upon the worst case scenerio; full system. The other half of the wattage recommendation (+12v amps) is as important. The GTS will run on your +12 volt rail; you can have a healthy 500w power supply that is incapable of running a 8800. Making sure the +12 volt meets the recommendation is your primary.

    Thanks Blacken. I just contacted Gateway and asked if my 400 watt power supply comes with at least 26 amps on the +12v power rail. I'll probably get a response Monday.

    Can I find out by going into the tower?
  3. You could. Just look for the Powersupply sticker on the powersupply and read back how many amps are on the +12V rails. Im highly recommending however that your gateway Powersupply wont be able to cut it. But who knows.

    Thanx EnforcerFX. I'm not sure how to read this but here is my power supply specs:

    400 W MAX.

    +12V / 18A, +12Vcpu / 16A
    +5V / 18A, -12V / 0.3A
    +3.3V / 25A, +5VSB / 2A

    +5V and +3.3V 130 W MAX
    +12V1 and +12Vcpu 30A MAX

    +12V1 and +12Vcpu 30A MAX

    it would be safe to get another psu.
  6. Yea, I agree sirheck. I found out my current power supply has an available 30 amps on the +12V rails, but it doesn't leave much afterwards.

    I'm gonna go for Corsair's 520 W Modular.

    Thanx guys for helping me out.
