Yet another PSU question! The Netherlands, Azerty, €120 - €160 budget (probably same in US$)

Equanox · October 29, 2015

Hi guys,

So here's the thing, I have a Sapphire HD 7770 GHZ edition videocard and since I couldn't afford a new card I decided to buy an identical card off the internet (second hand) to put in crossfire. The card works perfectly (if their not connected at the same time) but when I put them in crossfire my 600 wat OCZ power supply can't handle it. Framelate drops, crashes and slowdowns appear while all temperatures are fine and CPU/GPU loads are below max. So I need a new power supply..

I've found 2 PSU's that I really like and although I read 750 watts is enough to power these cards in crossfire I want a bit extra (850w) for future upgrades. I really don't know what the difference is between these PSU's and maybe it all comes down to personal prefference but I would like your opinions on it if I may

Personally I would like the Corsair 850 watts HXi series but my budget will not allow it. So what do you guys think? Is any of these 2 options the right one? Is there an alternative? My budget is pretty low but I do not want to cut corners on this item. Are there any good alternatives?

Thanks in advance!
