I would've thought the same, but 3820 and 6950 are quite more power hungry that the setup that I used to run on my PSU which is now 3 years old. This is what I used: http://extreme.outervision.com/psucalculatorlite.jsp
Even with the modest settings it recommends me a 550w PSU and if I enter all the stuff I have (8 fans, 5 HDDs, fan controller) and add capacitor ageing it shows 650w.
Now as I replaced the 6950 with my old 5770 the issue is gone which could point at the GPU being the problem. However I've tested the 6950 previously in my old setup (q6600) and didn't have any problems with it. In both cases though the power draw was lower, so the PSU is another possible explanation.
The strange thing is that the freezes don't seem to appear under heavy loads with stress testing, benchmarks or games but always happen during internet browsing, watching youtube, reading ocn or using facebook.

HALE90 is over budget but worth it, I'd take it over the AX750/X760. Speaking of which, the AX750 is £130 Inc VAT and not superior to the HALE90 (and the X 760 itself is £144)
The Highpower made OCZ750FTY isn't a bad unit, but you can do better, like the above PSU's. I haven't looked at EU/UK PSU's in a while, there could be better deals out there.

Thanks. I think I'll go with HALE82. Do you know how it compares to other Seasonic based PSUs in the same price range like Corsair TX M or XFX?
