The EVGA 750W is a great choice for 970 SLI.

Has all the connections you will need for SLI.

I would choose.

EVGA 750W G2

Made by the BEST = SUPER FLOWER

If my math is right, CPU should be 100 watts, 200 for 970 and another would be 200. So 500 W plus peripherals, harddrive uses maybe 30 watts. So should total 530-550 watts.

Should be fine. One suggestion would be to buy a cheap wattmeter to see what your system uses now. U can see what a 970 uses if you read reviews.

Does the PSU have the additional power connectors you would need for a 2nd card?
