I just purchased a new Asus motherboard and a CoolerMaster Elite Power 460W Power supply. The motherboard has a 3-pin PWR_FAN connector. However, the PSU does not have any cable that would fit this connector. Is it safe to power on the motherboard without this connection?
Also, a cable coming out of the PSU is called "CPU 4+4 Pin Connector." The pin description says COM, COM, +12V, +12V. I don't see any connector on the motherboard that will take this cable. What is this for? Is it okay not to connect this cable?
The motherboard's 3-pin PWR_FAN is a connector for a case fan, absolutely do not try to plug in a PSU cable into it. If you don't have a fan connected to it then it will be no problem to turn on the computer.
The 4+4 pin connector is probably for the CPU and if you look on the motherboard near the CPU socket then there should be a 2x4 row which will accept the 4+4 pin connector.
Sorry if I was not clear. The motherboard cannot monitor the PSU fan speed unless the PSU supplies a cable that can go in PWR_FAN connector of the motherboard. In my case, the PSU does not provide this cable.
