The GT620 is a low power card that should run on that PSU as long as it is modern.

For a system using a single GeForce GT 620 graphics card NVIDIA specifies a minimum of a 300 Watt or greater power supply that has a maximum combined +12 Volt continuous current rating of 18 Amps or greater.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

The HP OEM 240 Watt power supply meets or exceeds the maximum combined +12 Volt continuous current rating required for a system using a single GeForce GT 620 graphics card.

+12.1Vmain === 14A
+12.1Vcpu === 12A
+12Vsb === 1.3A
-12V === 0.15A

The 80 PLUS database shows that the power supply was tested under full load with the combined +12.1Vmain and +12.1Vcpu at 18.7 Amps.

It's definitely not a standard ATX12V design since there's no +3.3V, +5V and +5Vsb rails.

So, Then, This power supply will work? or its just gonna blow up?


EDIT: sorry, I dont really understand that... Only that it has more then it needs?

The power supply meets NVIDIA's recommended system power supply's combined +12 Volt continuous current rating requirement so it should work. The power supply's total wattage isn't what matters.

You say you have it running right now, so what's the problem?
