Power supply won't turn on when connected to motherboard

Recommended Posts

Posted · Original PosterOP

Hey guys

I just bought a bunch of new components and couldn't get the build to power on. I put everything together and couldn't get anything to power on, the PSU wouldn't even turn on when connected to the motherboard but would power on with the paperclip test. I couldn't jump the motherboard, tried different ram seatings, 1 stick of ram in different seatings, checked GPU on my old motherboard and double-checked PSU at the same time, made sure fans weren't shorting the motherboard. The only things I couldn't check individually were the RAM and CPU as my previous board is an intel B360 Gaming Plus board and only supports up to 2666mhz. I've returned the board and their testing team has said they couldn't replicate the fault and that the board has no issues.

The components I bought were

Gigabyte X570 gaming + motherboard
AMD ryzen 7 3800x CPU
16gb DDR4 FlareX ram @ 3200mhz

The components I added were

Cougar GX800 V3 800W 80+ gold PSU
RX Vega 64

Do you guys have any idea what could be causing the issue? need help urgently

Thanks in advance

 

Should add that the PSU and GPU are in the computer I'm using now and working perfectly

It should work regardless. If it doesn't then your RAM kit is borked.

Make sure you've connected all required PSU cables (GPU, CPU). Clear CMOS. But if motherboard doesn't even try to startup you're either doing smth wrong on the lowest level (like you've connected power button to wrong jumper) or it's dead.

You're saying try the new RAM on my intel board? It's g.skill flarex and i believe its built specifically for AMD boards

That's bullshit, if it's DDR4 then it's universal.

Also, were this PSU bought recently or you had it for a while now ?

OK, I'll try the ram in the intel build. I feel like I should mention again that the power supply won't power on when connected to the X570 board but will power on with the B360 and with the paperclip test and that the X570 has been sent away to be tested and came back that the board has no issues

Do any lights on the motherboard ever turn on?

Again, are you sure you're connected motherboard power switch cable to the right jumper ? Did you try to short the jumper manually ? Refer to motherboard manual and double check that.

Hate to say but it's about 8-10 years old design actually. Not very bad actually but i wouldn't buy it today.

PSU powering on just means fans spinning?

Usually a motherboard will have some ambient LEDs, or at least will turn on an LED when you attempt to power it on.

If this doesn't happen and you're sure that you're powering on the motherboard correctly, then I guess it's a bad board?

Yeah, unplugged everything from the motherboard and used a paperclip to start the PSU and it worked fine (as in the fan turn on) and its in the computer im using now working fine but when plugged in to the X570 the fan doesnt turn on. Tried connecting an RGB case fan to the mother while the PSU was hooked up to it, no lights, no fans, no nothing

Yeah, tried to jump the board with a screw driver. Regardless, the PSU won't power on when connected. Just to clarify, when testing the power supply to the board, I'm plugging in the 24 pin and the 8 pin connecters while the cpu is in. trying again without the cpu and with/without the 8 pin. Then again with just the mnotherboard and a case fan. In all cases the PSU doesn't power on

It would still work in an Intel system, and likewise the DDR4 RAM in your Intel build will also work in your Ryzen system.
Though it won't be an issue with your RAM as even without RAM installed at all you would still get some signs of life when you try to power the system on it will just fail to boot and either display an error code or sound an error beep code. You'd notice the system at least try to start.

 

Make sure you're trying the correct power switch pins on the front panel connector - They might not be in the same spot as your previous B360 motherboard.

As per your X570 motherboard manual:

You're not using any custom cables or extension cables or anything? Cables from a different PSU?

Yeah those are the pins I tried to jump the motherboard with. I'm just using the power supply as it came out of the box. I can't find anyhting online that the PSU wouldn't power certain boards or anything like that so I'm so confused on what to try when the motherboard eventually arrives back here.

Then that is very strange indeed. I'm not sure why it would work with your other system but not the new one.

Did you have a spare power supply that you could use to test with the new system?

Hey guys,

 

The RMA team told me at first that the board had no faults but ended up sending me a brand new board anyway. builds done and it's running like a dream. Thanks for all your help, guys. I really appreciate it!!
