5830CF on my 600w PSU

post #1 of 43
Thread Starter 
Hello all, quick question, is my PSU capable of powering 2 5830s ?
I have 2x6-pin cables but i can use the 4-pin to 6-pin adapters (Unless it's too risky).

Waaaaaaaaaaaaaaaaaah? If course it can! He could even run it on a 500w if he wanted too!

Guru3d tested crossfire 5830 power consumption, they recommend 650W for 2x 5830's but keep in mind they overestimate by 50-100W, but they also recommend adding another 90-125W for quadcores, so I guess it cancels out.

You've got a quality 600W PSU, so you should be fine with 2x 5830s unless you have lots of flashy tube lighting in your case.

You can use molex to PCI-E connectors, it's not advised, but if you're going to do it, please use the 2 molex into 1 PCI-E connectors.

You had them connected with molex to 6-pin? Or your PSU has 4x6-Pin cables?
