If that PSU model is "white listed" and appears on this OCN thread, then go ahead and get it:

Make sure to get a power supply with at least 25A on the 12V rail, and is approved on that thread, for a single HD7950.

For HD7970s, you will need a power supply with at least 30A on the 12V rail.

This PSU has two 12V rails with 18A and 20A. This is below required spec for 7970 but could work.
You'll be on the border and probably shouldn't overclock.

I can get my overclocked 7950 to consume 22-23A.

I've noticed that the PSU does not have 8pin PCI-E connectors, so you will need to use converters from Molex.
You need 2 Molex connectors for each 8pin PCI-E so you'd need a total of 4. Your PSU only has 2.

For me, all things considered this is a no-go.
