AsRock H81 Pro BTC R2 - Do we connect both ATX power on Motherboard?

[aviz123]

Hello Friends,

Currently i have both ATX power connected on my motherboard.

Should we connect them both.. or just connect the 24 Pin ATX Power.. and not the 8 Pin ATX12V1 Power on motherboard

Thanks....

That 8-pin connector is what powers your CPU - IT IS REQUIRED NOT OPTIONAL.

That 8-pin connector is what powers your CPU - IT IS REQUIRED NOT OPTIONAL.

According to the manual, you can also use a 4-pin CPU power connector.

This motherboard provides an 8-pin ATX 12V power connector. To use a 4-pin ATX power supply, please plug it along Pin 1 and Pin 5.

Do you mean the two molex connectors?


or

the 4-pin CPU power connector?


For the molex it is not necessary to connect them if you are using powered risers
For the 4-pin CPU,  IT IS REQUIRED as the other guys have told you

Without the 4 pin the Motherboard will not work, so that is REQUIRED

The CPU connector - if your CPU is low power, then it should be safe enough (since the motherboard manual specifically MENTIONS it) to just use a 4-pin CPU connection instead of an 8-pin.

 The molex connectors are intended to power the PCI-E bus connectors for use with non-powered risers.
