Title: Can I supply a GPU with a Server HP PSU? Post by: Sirvaude on April 10, 2016, 07:18:37 AM Hi there, I have a doubt.
Can I give 12v to a GPU (turn it on) before I turn on the mainboard? would that be a problem? I have a Gigabyte 7970, and a MSI Z77A-GD55, I also have a generic "500 Watt" PSU to supply the mainboard, and a HP DPS-1200FB PSU; I'm wondering if I can use it to supply only the GPU. Assuming that I can supply the GPU with that HP PSU; Due that those PSUs works separately, do I need to turn them on at the same time? or can I turn on the HP before the generic one? AFAIK, I can use a relay of 5V or 12V connected to the generic psus 5v/12v rail... so, it will turn on the PSU at the moment I turn on the mainboard... but before I do anything and burn something I need to know if I'm right or how should I do it. Thanks in advance. Title: Re: Can I supply a GPU with a Server HP PSU?

This should work. If you can line the PS_on pin to the server PSU, that should also work.

Post by: sirslayer on April 10, 2016, 08:13:46 PM i have a dell 2950 server and i also using an external power supply from another pc.. my dell server have 2 built in but not enough plugs.. you first turn on external and the server next.. my server have a integrated video so if i turned on the server first the integrated video kicks on first
