Recommended powers supply for a 7950 build

[luis94uk]

Running a build composed of

Radeon 7950
AMD FX 6300
gigabyte-ud3-fx990x motherboard
(faulty) 850w xfx pro series psu

pretty much issues began right after the psu was put in , it would crash like once a week , and now it wont load up at all ( fans light up and spin for a split second but nothing more , tried plugging in my older 400w and it would work fine )

so looking for any suggestions for a good for money psu for a 7950 build , possibly some room for XFIRE 7950's but not required.

no budget but would like a reliable good for money psu ( nothing over the top , not looking for the best but something that will do its job )

Thanks for any help !

Any decent psu with 500-600W range, for crossfire any decent psu within 700-750W.

A psu for the single one : http://uk.pcpartpicker.com/part/xfx-power-supply-p1550sxxb9
If you want a psu with crossfire option : http://uk.pcpartpicker.com/part/xfx-power-supply-p1750xxxb9

If you dont want XFire buy a good 650W psu like the Corsair TX650M. If you do want to Xfire buy a great 850W psu like the corsair HX850 or the Seasonic X850. But if you want to save money and do Crossfire a Corsair TX850M would do too. But id recommend the HX instead as it has better efficiency...
