Which PSU for FX-8320 and HD7970?

[Krivi]

My specs:
FX-8320 (LC-Power Cosmo Cool LC-CC-95)
ASRock 970 Extreme 4
AMD Radeon HD 7970
+ 1 cooling fan

I do plan to OC and my budget is ~70€
Thank you in advance!

Any good quality 550~600W PSU would be sufficient.

A good 550-600W will be fine.

Pick something in Tier 1/2 here:

Ok, thank you.
And if I put another HD 7970 in crossfire mode?

 

[dudeman509]

750. Make sure it has enough PCIE connectors.

I would go over-spec a little on the PSU.

You will get the best efficiency and keep fan noise low if you run in the 60% load range. Plus a 750w PSU isn't much more expensive compared to a 650w.

Yeah guys, I have the idea that it needs to be around 750w, but could you recommend me quality models for my budget?
