CrossfireX 5770's Power Question

>>PhoeniX<< · Feb 28, 2011

Ok so I am about to crossfireX my new 5770 along with my other one on an MSI motherboard. On the 5770 there is only one PCIe power and my power supply line has two. Because my card only uses one power plug, can I use the other one (6+2 PCIe) to power my second card? Because then it will save me another slot on my modular supply and another cable to take up space.

Just a question. Any replies would be great! Thanks <<PhoeniX<<

Yes it will work, but make sure your power supply has enough power for those 5770's,
List your system specs too

850 is more than enough, is it crossfire /sli ready? you will get the best performance out of that. 850 can even power 2 5870s, your good to go

my rig at idle pulls alomst 200w at the wall, and stock cpu and gpu load is only about 500w 5770's are super power efficient, one pci-e cable is more then sufficient.
