Question

Can a PC start without CPU

by Ege_Gunduz / January 11, 2016 2:43 PM PST

Hey guys. I wanted to test my system before I get a CPU. I wired all the cables to my brand new motherboard (AsRock z97 anniversary) from my PSU (FSP 700w) I have ram 1 stick 8gb in channel 1 and all front pannels connected for my NZXT s340. I plug in the power supply turn it on press the case button and nothing happens. No case lighting no psu fans nothing! Should be concerned?

That's because the power supply...

did not get the signal from the cpu. However, it can be turn on by a jumper wire. But I'll let you do the research for that. In any event, even with the PS on, it won't tell you much just looking at it. Have fun.

Have on some boards.

But I would not install memory or any cards. There is a GREEN WIRE TEST but I find this only useful without a board.

You need a minimum amount of parts to bench test a computer . MB, RAM , CPU ,PSU and cooler fan.
I would also use 2 sticks of RAM so you can use dual channels .
