Power turning on and off?

post #1 of 21
Thread Starter 
Hi guys so I'm in the middle of my build right now, and I have my motherboard connected screwed in the case and everything.

Have my PSU screwed in, connected with the Front Panel, hd audio, and front usb.

Though I don't have my CPU, SSD, and Graphics card yet, I was hoping to test to see if my PSU works properly, and when I flip the switch on the fans and the Phase LEDS come on the Mobo, but then it switches back off.

Do you guys know what the problem is? My motherboard is a Gigabyte GA-Z68XP-UD3P

I do have the CPU power connected properly I think..

Here's a better way to test your PSU.

I don't know if it's a good idea to be turning it on without the CPU. I think that's the one thing you have to connect for anything to work. Well, that and the memory. You don't need the GPU, HDD's, etc. to get into BIOS.

Just my 2c worth...hope it helps,

Rich

Oh okay so I might need the CPU to get it to stay on... huh? I have RAM too installed.

Can anyone verify this I need the CPU?
post #4 of 21
TBH I've never heard of anybody trying to turn on their MB without the CPU...I guess it might be possible.

I just think of it like taking the engine block out of your car then trying to start it. You might have a battery and the starter may turn, but you don't have anything to start.

I see that makes sense, well then I shall see if I can do something about the CPU.
post #6 of 21
You should at least have CPU/RAM/GPU installed.
post #7 of 21
Would he have to have the GPU installed? It is a Z68 board.

Yeah that happened to me on P35 all the time, PSU works fine. Motherboards will keep power cycling unless there's a CPU in it. Basically, if the PSU doesn't work...nothing will turn on lol

Oh thanks a lot redsunn now I have a reason to convince my mother to lend me some extra cash to get my CPU early.

Thanks for being ever so helpful everyone.

Bare minimum for boot as far as I know without something like that happening is at least one stick of RAM and a CPU.
