PC Fails to power on upon being put together

[DenShazo]

Hello!

 

I recently put together a brand new PC for my father, who wants to use it for video editing. Upon testing out the first power supply, a Thermaltake SMART 600W ATX 12V V2.3/EPS 12V 80 PLUS Certified Active PFC Power Supply PS-SPD-0600NPCWUS-W, there was no reaction from the motherboard. The box it came in was slightly beat up so i chalked it up to the PSU being damaged and reordered another. The box the new one came in was pristine, yet it still failed to power the PC so i am lead to believe the problem lies elsewhere. I did some research and apparently some motherboards have pins that have to be bridged(?) for power run properly.

 

This is my first time working with AMD and it has proven to be a headache, so any help would be appreciated.

are you sure the power button is plugged in correctly and actually works?

[Jeruzalem]

are you sure you connected the power button cable in the right pin? i think that is the first thing that should be asked.

It's not that the power button doesn't work. When i connect the PSU and flip the switch on the back to provide power to the PC, the lights don't flash and fans don't move.

He means the cases power button and wether it is connected to the motherboard ( if you don’t know where it is just read the motherboards manual ) ( if you already thought of that I don’t know what to do)

[DenShazo]

This is what the wiring looks like at the moment.

its not an amd thing. the front panel connectors have been the same on both intel and amd for years.

they aren't supposed to. it happens on some systems but not all. I believe the tomahawk doesnt do it.

 

This is from Page 17 of the Tomahawk manual.

make sure you're plugging it in right.

can i have a closer look at the bottom right of the motherboard

and are you sure you sent the right pictures, first image looks to be a tomahawk the other 2 images look to be an aorus board

This is a closer look at the JFP1 section. The only missing things are the reset switch 

[emosun]

is your power switch connected to the correct pins and does it work?

sorry 

[emosun]

are you pressing the power button or only the psu switch?

The pins are correct, as far as the diagram goes.

 

Just now, emosun said:

Both. It doesn't power on.

[emosun]

unplug the button and just short the pins to see if that works

if not then check you have the cpu power plug in , not the 24 pin but the 4-8 pin.

If still a no go , then remove anything the machine does not need to simply power on (drives , cards , fans , ram) and see if that makes it power on.

[DenShazo]

Update: pulled out the GPU, and reinserted the psu + front panel cables.  No dice.

What do you mean by shorting the pins

[Jisagi]

Just to throw in another idea here: He could also try to jump start the PSU standalone and see if it even works. This is not *that* beginner, but the best way to test the first device in the whole chain. You can find many tutorials for this on the web, but I am hesitant to suggest it to a beginner, since this can (in theory) damage the PSU and pose a threat to you as well. But in generall, you manually short the pins (top row from the left: 4+5) to start the PSU which would normally be done by the board. It's basically the same as suggestion of emosun, just one step before that, to exclude the board from the equation.

If the PSU works, the mainboard would be my next guess. Try to short the pins, as emosun aleady suggested. If that doesn't work, try to get a new bios battery and if that fails, too, it really does sounds like the board is either dead or has some other problem a new board shouldn't have.

I will try these and see if it works

I forgot to mention that there's a cable from the front panel that's there, but I don't see a place it can be connected to on the motherboard

Reseated the CMOS battery before I tried shorting the board using this video as a reference 

No reaction.

If shorting the board doesn't help, trying to short the PSU would be a good way to check that individually. Here are some good instructions for that. https://www.silverstonetek.com/downloads/QA/PSU/PSU-Paper Clip-EN.pdf

If that doesn't work and the PSU refuses to power on at all, it's dead or the cable for it is broken, but either way, it fit for RMA.

The short test worked for the power supply! Gonna reconnect it to the mobo now to see if everything boots up as well

[DenShazo]

Shorted the Mobo with the PSU and it came alive!

I didn't know about shorting pins on the mobo, or jump starting PSUs before this so i appreciate you all for enlightening me. Learned a couple of new things these past few days.

By the way, i dont know if I missed the answer. But the connecter that you showed a picture of and didnt know where it went, is for the front usb type c. Unfortunately, the tomahawk max does not have support for that, but there should be a type c on the rear i/o though
