2 Power supplies

post #1 of 8
Thread Starter 
I just got a pos comp with a 250 watt power supply...
And I bought a new videocard but it doesn't have enough power so I was wondering If I could use a second 250 power supply just for the video card...

BTW vid card is 6800gt

I heard I have to manually turn on the power supply, how do you do that?

I suggest buying one effect PSU, there are some good brands like SeaSonic & PCpower.com. get one with at least 500W.

Don't. With older PSUs, there is the issue of cross-loading or load balancing. You would have to make sure that the 5+3.3v rails have enough load on both PSUs or the 12v line will be poorly regulated.

This link will show you how to hook up two psu's so that you can turn them both on when you turn on your computer.

I did this with a 400w and a 350w psu, and the 350w solely powers my 8800gts. The second psu also fits nicely in two 5.25" drive bays.

Check out the link in my sig to see how I did it.
