So guys, need help on this one. I currently have an 80+bronze hec cougar 700w psu (non-modular) and i was hoping to xfire 5850's. I was wondering if it would be enough to power everything.

My specs as follows:

cpu: amd phenom II 965
mobo: asus m4a79xtd evo
ram: elixir ccd 9-9-9-24
psu: hec cougar 700w
5'25 bay drive: lg cd/dvd burner
scythe fan controller
case: lancool dragonlord pc-k62
case fans: 5 red led yate loons
heatsink: thermaltake frio (push pull config)
case lighting: 2 dual red cold cathodes
hdd: 3 hdds (500gb and 2 1 tb's)

would i be safe to xfire with a 700w unit with all that? Thanks in advance.

There are multiple 700W HEC Cougar PSUs, can you open up the case and post what it lists as the load per 12V rail and combined power between the 12V rails, it will have a sticker on one side with a load table on it.

HEC has some good units and some not so good units, im not sure if you have one of the good ones or the over rated ones.

You will be fine with that unit as long as it is the same unit that JonnyGuru tested then it should have no problems with a pair of 5850's.

Sorry for the late reply..so essentially speaking it should be able to handle 5850 xfire right? Could i xfire a 5870 with a 5850? Would the his 5850 be ok? Or would the 5850 cyclone be a good buy?

Edit: ill have pictures of the psu up a little later..sorry..and thanks again for the help guys..
