Hi I'm currently thinking on adding a second gpu to my rig just wondering if my psu will be sufficient enough to handle the new load.

Current specs

I5 4670k

1tb hd

Xfx 750 watt psu

Gigabyte gtx 770 2gb

8gb ram

Cd drive

Asus z87 a mobo

I'm wanting to ad another 770, if I forgot a spec sorry will add if needed

As you are planning to add a second card, the 750W will suffice.

Such poshiness

Very formal 

Much perfect

:lol:

In the grim darkness of the far future, there is only a GTX 1080, just a single 1080, where my glorious PC once stood....

For that is all I need, For the Emperor of Man, Jen-Hsun Huang, protects. We march for Nvidia, and we shall know no fear!

If that's the right PSU, you have 62A on the 12v rail. That's Nvidia's requirement for SLI exactly.

You CAN SLI, but you will have very little breathing room for overclocks and additional mechanical hard drives.

if you have to insist you think for yourself, i'm not going to believe you.
