adding power supply to hp desktop for gaming gpu

DO AT YOUR OWN RISK

it seems to work just like any other gaming computer after adding the gtx960 with a 6 pin connection.
originally ran a gtx1050 but bought a used gtx960 to experiment on.

YOU NEED TO ADJUST THE POWER SUPPLY TO 12 VOLTS!!!
also switch it to 110/220 volts depending on your power source.

i used the cheapest power supply i could find. they make better ps that can be switched on/off or you can wire a switch into the supply. i had to buy a second power supply because the first one did not work.

if you wanted to add a better graphics card, you would probably need to get a vertical gpu mount or find some other way of mounting it.

parts used:
110/220 12v 20a 250w power supply ($10)
6 to 8 pin pci adapter ($3)
300v 18 awg 120v plug ($8?)
Gtx960 gpu ($50)
