$400 EVGA X58 Mobo Can Burn Up 24-Pin ATX Pin When Using 4xHD4890 Under OC (+fix)

jmke · 13th June 2009, 17:55

Whe making the Classified I did take precaution to increase trace thickness for the 4 PCIE slots for the 3 groups of power. As before when overclocking quad fire 3870 I found they eat a lot through pcie slots.

This way the trace does not burn up, or restrain cards oc in quad fire.
However as there are only 2 +12v yellow wires, the connectors thus get hot at the 24pin ATX.

I myself have melted the 24 pin ATX connector when running 4 x 4890 oc.

if you have cash for $400+ mobo and worthy CPU to go with, 4x4890 is peanuts

Hehe,

Peanuts to some maybe, I just think 4 x any GPU = complete waste of cash.

Hm, isn't this exactly why boards used to have a molex plug for additional PCIe GPU power...

Was wondering why many X58 boards no longer use additional PCIe GPU power sources...
