Do I need a new power supply?
I am planning to get a new video card. An EVGA or an XFX 9800GTX+ (both have similar requirements and performance rates). Anyways, both say they recommend at least a 450W power supply and a +12 volt rating of 24 Amp Amps.
I have a Thermaltake Purepower 500W power supply, but I have no idea how to read the chart on it. Its pretty recent so Im thinking ill be okay, but I just want to make sure. So ill type up the chart here:
+3.3V +5V +12V1 +12V2 -12V +5VSB
Max Load 22A 32A 14A 15A 0.3A 2A
Min Load 0.5A 0.5A 1.0A 1.0A 1.0A 0.0A
Load Reg. 5% 5% 5% 5% 10% 5%
Ripple V. 50mV 50mV 100mV 100mV 150mV 50mV
So i was wondering if someone could tell me if i absolutely need a new power supply and recommend one if i do. Or even better if you could tell me how to read that chart. Thanks!
the +12V and 24 Amps means the total on all +12V rails together. your PSU has two +12V rails, one with 14A the other with 15A (total 29A), so you’re on the good side.
