QUOTE(buraqdunia @ May 29 2021, 12:40 AM) See that red exclamation mark?. There is no either optional or compulsory involved. ALL POWER CABLES ARE SECURELY CONNECTED. Once plug in all, in avoid motherboard electricity overload, any step should i take precautions before? Any hardware should i unplug first? Boot up, and see see if no issue first  |

QUOTE(ceo684 @ May 29 2021, 12:50 AM) You use heavy machinery (i7 and GPU) combined, of course need to plug in all lah.. if heavy current draw cannot be supported by the cables, it will result in voltage drop. Nowadays assembling PC very easy got plug and matching socket kasi plug sama dia. Only need to worry if your PSU is too old that it doesn't come with enough/the right plugs. The reason why need so many plug is because the wattage is high, but voltage only 12V so those tiny cables by its own (from zaman pentium III) cannot sustain. Also they section off the power delivery CPU is CPU power section, GPU is GPU power section (PCIE bottom), probably for less fluctuation and other reason. If motherboard not enough power, pc will shut off / reboot, or just performance issue? For pcie pwr1, choosing not plug it, perform stress test would throw results. Correct? |
