Motherboard: XFX 750a SLI motherboard
http://www.tigerdirect.ca/applicat [...] CatId=3701

CPU: AMD Athlon X2 64 5200+
http://www.tigerdirect.ca/applicat [...] No=2470587

Power Supply: eXtreme Power Duo 600W
(sorry, no link).


RAM OCZ Dual Channel 4096 MB 800 MHz

Video Card: 9800 GTX 512 MB

My question: The mobo above has an 8 pin power socket, while the PSU only has a 4 pin power connector. There is no 8 pin connector, nor is the 4 pin actually a split 8 pin with the other laying around. I have searched many forums looking to find an answer to ... is it OK to put a 4 pin into an 8 pin socket. My findings have lead me to the conclusion that it depends on the CPU. So, can anyone tell me within reason and accuracy, If I can go ahead and build this computer with the 4 pin connector into the 8 pin socket?

Any help would be appreciated, thank you in advance.

Quick answer, Your OK

There have been several post on this subject on toms site.
(1) this connector primarily supplies power to the CPU.
(2) The positive Pins (+12V) are all shorted together on th MB, as are the Gnd/Rtn lines. Net effect is that it reduces the Current flow per wire.
(3) Primary reason for the addition 4 pins was to support HIGH powered P4 Extremes and where TDP exceeds 125/130 Watts And even here, the only problem is in wire gauge. In a previous post I posted the Current capaibilities for the various wire gauges - Don't have info handy

It will work if you plug in just hte 4pin onto half of the 8pin socket.
