If you can find it. Here's where I used that on a similar or same PSU.
The maximum power draw was 173W so that's pretty far under the max which is where we want to be.
Yes, yes, the boxes usually ask for 400 or more Watts but I used a Watt meter to be sure.
So i just wanna know if the Hp Compaq 6200 MT psu with 320W can handle this 750ti:
They recommend on a 400w PSU on the gigabyte site so idk..
Btw im pairing it with a i5 2400 and 8GB of ram
