5850 crossfire - 2nd card on molex to pci connectors?

[Nathlm]

Will this limit the overclocking or any other thing on the card?

If there is anything you can think of then please tell me!

By the way I have 4 12v rails at 18A each and 600w will this be enough?

It's an OCZ PSU

I ran my 5850's on a 650 watt with the molex to pci adapters for a while, I had no problems, but I would recommend getting a new PSU. I did, have a 950w now

Just try and see how it works I guess, and get a better PSU if you can in the future.

you should be okay - just OC them... leave them at stock

Why should I not overclock them?

I might just wait for the 7000 series then

on stock clocks you will be on the limit of the power draw of the PSU

OC-ing either, or both, may kill the PSU

if you want to have two in cF and OC'd... get a bigger PSU (min 850W)
