PCI-e Questions

post #1 of 4
Thread Starter 
I'm still thinking of what PSU to get and if i want to run 3 Graphics cards and a 850W PSU only has four 6 pins and i need six 6 pins is it possible to buy or make a 6 pin PCI-e cable with one connector on one end and then it breaks off into Two 6 pins on the other end

or will this blow my PSU or something crazy?

850W is more than enough to run SLI GTX560 + 9800GTX+ so this should work? or do i have to buy a PSU with TRI-SLI certificate which already has six 6 pins on it


Cheers for the help

Ollie

you can use molex to pcie adapters they usually come with your cards or you can buy them pretty cheap http://www.newegg.com/Product/Produc...82E16812887001

It really will depend on the amps your PSU can hand out. For wattage you're fine.
What's the Brand & model number of your PSU?
