Question 1x8 pin power connector psu on 2x8 pin power connector motherboard

[mightybaboon]

Hi, im new and i currently trying to build my first pc, im using Asrock b760 pro rs motherboard, the thing is my motherboard have 2x8 pin power connector while my psu only had 1x8 pin connector, can i use only 1x8 pin power connector to the motherboard?

Using both CPU connectors is almost always unnecessary, and it really only comes into play with aggressive overclocks.

(Note that this isn't the same for GPUs. In that case, you want to have all the PCIE connectors you need).

so its fine as long im not overcloking (aggressively) it?

You be much better off with 2x 8GB or 2x 16 GB.
You're giving up performance with the single RAM stick.

ill consider buying another one, how about the power connector? is it fine if i use single power connector?

No, not "buying another one".
A 2x whateverGB that comes as a set, in the same box.

oh i see

how about my question sir? about power connector, im still looking for an answer

Should be OK.

 

[mightybaboon]

Should be OK.

thank you sir

The second 8-way motherboard power connector really comes into its own in the unlikely event you're trying to win overclocking contests with liquid Nitrogen cooling. With two 8-way power leads plugged in, the overall resistance is reduced, allowing the CPU to draw more current for the same Volt drop along the cables. When the CPU is pulling instantaneous currents of tens or hundreds of Amps from the 12V PSU supply rail, even a few milliOhms can make a difference to CPU stability.

Yes. You'll be absolutely fine.
