Asrock Z68 Extreme4: 20+4 pin ATX power cable/connector

[cps1974]

id really appreciate some help

I have this mobo and to date have just been using the 20 pin ATX power cable/connector, the mobo manual does confirm I can use:

20 pin ATX power cable/connector

or

24 pin ATX power cable/connector



my PSU (Cooler Master GX 750) comes with 20+4 pin ATX power cable so will support both 20 & 24 pin motherboards

the system is running fine with 20 pin but I have since added a 2nd GTX 460 SOC (so now SLI) and Asus Xonar D2X soundcard (PCIe) and read that to ensure all cards get the power they require without stressing the 20 pin I should use the 20+4 pin ATX power cable, is this true - is there anything in what I've read/heard?

really value the Tom's members input so if anyone can confirm which I should use for the smoothest / safest system that would be great


thanks

If your PSU has the extra 4-pin connector, then why don't you connect it? It isn't an absolute requirement, but it won't hurt.
