I don't know much about power supplies but I need a replacement for the one stated in the title.

GTX 670
Z77X-D3H
i5 3570K

I have around £100 but can go a bit higher.

Sorry I meant to say 970, would that still be good, I probably won't be using SLI any time soon.

Okay then, thanks for the help.
