PSU passed paper clip test yet not working

10Exahertz · Jul 11, 2014

Hi I am making a new build however when I plug on the power supply into the motherboard the fan doesn't go onI tried the paper clip test
And the fan turned on
I'm just confused as to what to next
Yes I'm new to this

What PSU?

Make and model?

10Exahertz · Jul 11, 2014

Corsair 750m
And the motherboard
Is z97-g55 Sli

Dark Lord of Tech · Jul 11, 2014

Not the greatest power supply , but should be able to handle it.

All power plugged in 24 AND 8 pin on board?

10Exahertz · Jul 11, 2014

Yes as far as I can tell
I've hear of people not plugging it in all the way

Dark Lord of Tech · Jul 11, 2014

Sometimes it's the connection yes.

10Exahertz · Jul 11, 2014

I don't want to push the motherboard too hard
And thank you for responding so quickly

10Exahertz · Jul 11, 2014

What if it isn't the connection?

Dark Lord of Tech · Jul 11, 2014

Could be DOA board.

What is the build? It's possible that the CPU doesn't work or your motherboard doesn't support it out of the box without a BIOS update, which you can't do without a supported CPU.

Any system beeps?

10Exahertz · Jul 11, 2014

CPU = intel i7-4790k
GPU = EVGA nvidia 770
PS = corsair 750m
And I did not hear any beeps
But te fan in the power supply case isn't on when plugged into the mobo

Make sure you have the latest BIOS.

ksham · Jul 11, 2014

It doesn't list that CPU as being supported. And if it does work with a BIOS update, you won't be able to do it with that CPU. You'll have to get a CPU that is supported and use that to update the BIOS. In short, the CPU you have now is useless until that update. You can try borrowing a supported chip from a family member or friend. Aside from that, you'll have to buy a new motherboard (cheapest route).

Dark Lord of Tech · Jul 11, 2014

Yes it does it's there.

Dark Lord of Tech · Jul 11, 2014

It's supported.

ksham · Jul 11, 2014

Oh oops. Not listed alphabetically. Thanks for the correction.

Dark Lord of Tech · Jul 11, 2014

I agree , weird way to list it.

10Exahertz · Jul 11, 2014

I can update the BIOS without power though?

Dark Lord of Tech · Jul 11, 2014

10Exahertz · Jul 11, 2014

Right thats the problem, I have no power going to the motherboard, PS fan isnt on, so what do I do
and should it at least power on (the PS) regardless of the CPU

ksham · Jul 11, 2014

10Exahertz :

Not without power, not without a supported CPU, and unless you plan to use a flash drive, not without Internet access.

10Exahertz :

I already told you your options. There is NOTHING that you can do now with the parts that you have. You have to get access to a supported CPU, buy a supported CPU (a waste of money), or buy a new motherboard.

Lesson learned. Next time, make sure you check compatibility before purchasing.

10Exahertz · Jul 11, 2014

But then How would I ever update the BIOS for this CPU?, that makes no sense sorry

ksham · Jul 11, 2014

Do you skip my post? I said that you can't.

10Exahertz · Jul 11, 2014

Also from an electrical perspective the BIOS for the processor doesnt matter,if that were the case the paper clip trick wouldnt work?
right??

ksham · Jul 11, 2014

That only tests the power supply. The paper clip test doesn't actually provide any power to the motherboard. You know that right?
