How many GPU with 630W

[Dosmas]

Hi

I have this PSU right now

This CPU

This Motherboard

Running it with 7790 and 6870.

I can get my hands on a 7870 and there is enough room for a third. But I dont know if the psu can hold it.

So I either change one of them and run a 2 gpu unit or make a 3 gpu unit.

How should I proceed?

Thanks in advance

Get a higher Voltage one, Those are pretty good cards, but need higher voltage to mine efficiently. Fuller powered cards, the better.

Okey, I got this psu just a shortwhile ago, How much would that be different from another higher voltage PSU?

Im still looking to know more about the possibility of using a 3 card setup. And maybe for now compare it to a different PSU setup.
