My question is this: The graphics card requirements suggest a power supply with +12 Volt current rating of 22 Amp Amps.) The power supply specs are showing only as high as 18 amps. Is this going to create an issue with the power supply not being at the recommend 22 amps? Requirements for my graphics card are: Minimum of a 400 Watt power supply. (Minimum recommended power supply with +12 Volt current rating of 22 Amp Amps.) Minimum 450 Watt for SLI mode system. (Minimum recommended power supply with +12 Volt current rating of 24 Amp Amps.)

Thank you.
