Hi I just recently installed a 2nd 4850 in my machine with a single molex to pcie and it ran furmark perfectly crossfired doubling the framerate on my p35 but when I started playing games it blew up my chiefmax V2 550w. I ordered a Chiefmax V2 650w and a dual molex to pcie adaptor to balance the pcie out between the 2 strands.. my question is will the 2 molex to pcie be better than the single molex to pcie or will it still blow up my psu. thanks.

im running a E7200 @ 3.66

Why would you buy another Chiefmax, to replace one that has already blown up?

Be thankful all your components still work after the first meltdown, and buy your self a nice Corsair, Seasonic, Antec or XFX PSU.

Oh yeah, and check out this review of a Chiefmax PSU!

I also wouldn't CF on a P35. The second slot runs at 4x, and unlike newer boards, it uses PCIe 1.0.

Notice the first graph. If single card is 100%, the P35 and 965 (same chipset with a memory tweak.) score about 98% of what a single card can do. Buy a real PSU, and sell both your 4850. Then buy a new GPU like a 6850 or 6870.

Best solution

I think that after the first psu blew up you would have bought a better brand of psu , but if the Chiefmax is what you want then that is what your going to get and the two molex to 6 pin is much better than the one to 6 pin. I do know that a better brand of psu will come with a 6 pin connector and you wouldn't have to use an adaptor.

This psu is on sale right now at Newegg and it comes with multiple 6 pin connectors and you won't have to worry about it blowing up. I don't know your budget and I don't know if you already have the other psu yet but you do want to get a high enough psu to have extra room and not be right on the edge of just enough.
