PSU Question - Connectors Tags: Power Supplies Pci CPUs Power Components Last response: May 31, 2009 9:05 PM in Components Share blargsman May 31, 2009 6:32:23 PM Okay, I made a newbie mistake and bought a 8-pin CPU power mobo when my PSU is only a 4-pin. Are there any problems with buying an adapter for that 4-pin PSU in converting it to an 8-pin? Or is that only possible for PCI-X? Actually, I have a molex to 6-pin that I could use for my PCI-X graphics card (will it work?). If I can replace one of the two PCI-X and insert it as the 8-pin to the CPU power, will THAT work? The PSU doesn't come with a 4+4-pin. In any case, does it matter where what wires go where? Does the PCI-X connectors HAVE to go to a PCI-X input?

Dont even think of using those PCIe power plugs in a EPS12 mobo connector, wire layouts are different and it shouldn't even fit physically. | Report abuse Devastator_uk May 31, 2009 7:36:36 PM 4-pins should be fine for dual-core. | Report abuse jsc Power supply Master CPUs Master May 31, 2009 9:05:26 PM The 4 pin plug should go into the 4 pins nearest the CPU socket. Your motherboard manual should cover this. | Report abuse Register or log in to remove Ask the community Publish Tom's Hardware>Forum>Components>PSU Question - Connectors> Related ressources: ForumMy dumb mistake-- question on PSU ATX connectors ForumQuick Question on PSU Connectors ForumCould I use this graphics card with my psu and connectors ?
