Not running enough amperage to a GPU

[imakamakaze]

Hello,

I have a GeForce GTX 550 Ti.

My PSU is rated to give 18.5 Amps on the +12 volt rail but the GPU I have requires 22 amps.

I have a 500 watt PSU, What will happen if I continue to run like this?

Okay you've bought a great power supply.

Try going to Nvidia control panel, Manage 3D settings, and on power management mode settings select "Prefer maximum performance".

Futhermore, you still haven't verified if it's happening with your old card.
