Mobos with 24 pin PSU connections

[perdomot]

I've got a Chaintech VNF4 that has the 24 pin but am using an Antec PSU with 20 pins to power it and am wondering if this could affect OCing? Does anyone know how big an impact the new 4 pins have when pushing a rig to its limits? Where would it be most noticeable, ram, cpu? Thanks.

The 4 extra pins are afaik for providing more stable power for the PCI-E parts. But dont forget that the 24-pin connector is only one part of the ATX2.0 standard. Other improvements over ATX1.3 are s-ata and pci-e power connectors, higher efficency and thus less power consumption and two seperate 12V rails in the case it has more than 18Ampere on the 12V rail. Here comes the 4 extra pins into play, cuz they contain the second 12V rail. That makes sense if u think of the power requirements of lets say a high-end pcie-graphic system, or SLI. The 4 extra pins make it more stable. For overclocking i am not sure but i dont think it will make a big difference, as long as the PSU u have is good quality.

Thanks for the info BBA. Hopefully, it will benefit the OCing by providing stable power.
