Is a OCZ ZS Series Power supply - 750 Watt enough for a 7770 crossfire(yeah i know i should just get a higher single gpu but i just wanna try the crossfire setup) and I'm also planning to add 2 120 SSDs in the future without any issue?

I currently have a 500w psu and it doesn't support Xfire so I really need to upgrade it

My PC specs:
AMD FX-6100
Arctic Cooler 7 rev2
8GB ram 1333mhz
Asus M5A97
Seagate 1TB HDD
Powercolor HD7770 1GB ghz ed
3x120mm fans

the other 7770 card is an Asus hd7770 2gb ghz with dual fan

Don't get CF HD 7770's, get a better single card as the performance will be "worse" doe to microstutttering.

But yes to answer your query.

It's almost overkill, in fact. But I also generally recommend getting a better single card instead.

well adding a 7700 would be more economical for him if he already owns a 7700, :) 

and yeah that ps is more than enought :)

Hi :) 

I went for an OCZ 850 for my 7990, which is like 2 x 7970s ...

All the best Brett :)

Thank you for the input people

Yeah I was actually contemplating to sell my 7770 and just get a 7870 but then again I already upgraded my mobo just to try xfire so I might aswell lol

what he is saying is that if 2 7970's can run on 850 the 2 7770's will have more than enough power

Sell your 7770 then get a 7870 then Xfire that in a year when you get some more money. I would say you shouldn't xfire anything lower than a 7850 2gig model at this point even that's not a good idea. however you could sell your 7770 then buy a 7850 now ifyou don't have the money for the 7870.

@devilofdeaths: my bad i thought he misread 7770 for 7970

@ikaz: i bought the gpu already lol i'll give 7770 xfire a try first then if it really sucks then ill upgrade to 7870.

btw how do i close this thread?

The OCZ ZT power supplies are great, but they usually cost quite a bit more than the ZS power supplies.

tru but paying a small premium for a bit more quality is worth it :)
