Can My PSU handle the jump to SLI?

post #1 of 5
Thread Starter 
I'm considering buying a second GTX 570 for my system and before I get too far down that road I wanted to make sure my PSU could handle it.

I've got a Corsair 850TX

My systems specs are:

ASUS P8P67 Pro
i5 2500k at 4.5 Ghz (1.32v)
EVGA GTX 570 at 800Mhz
16 GBs of Corsair DDR3 1600Mhz RAM
1T HDD
1 CD Drive
7 Cases Fans
Astec Liquid CPU Cooler

I used the PSU Calculator Program that was pinned on the forum here and it said I would need 750W with the additional 570.

I just wanted to come here and make sure. Will my system be able to handle the addition of another 570?

I only have 750 watt PSU and I was sure when I bought it that is would be enough AND have room for more things if I added them.
