New pc build, nothing happening when turning on

[kkeinan3]

Hi guys, I recently bought all my components brand new as follows,

mob- b450 Carbon pro ac 

cpu- 2600 with stock cooler 

ram- 3000 ddr5 Corsair 

psu- evga 550 g3 gold 

sapphire Radeon nitro+ 4gb rx580

 

After plugging everything, everything sits in properly, tried few times and check several times, all power connectors is well connected.. when I turned on psu, the psu fan, cpu cooler fan both not spinning, 

upon pressing the power, I can see a red light in the corner lighting couple seconds then goes off, 

psu fan is spinning when I used the power on self test.. 

i can’t figure out what’s the problem here ? Why the cpu cooler fan not spinning, is there any problem with the motherboardsz ? Thanks in advance ..

If I remember correctly, red LED is CPU error.

I even tried without the cpu power connectors, the lights still flashing 2 second then stop, im using 2x4 pins connectors for cpu , there’s another 4 pins  block beside it but the psu cables for cpu is only 2x4 pins..

Have you checked to make sure the cpu fan on the cooler is plugged into the cpu fan header? Sometimes computers won't power on if it can tell that the cpu has no fan to cool it. I know I have accidently plugged my cpu fan into a case can header and had this issue.

It’s connected in the right place, hard to miss it, cause it’s just besides it..

The extra 4 pin is an optional thing for extra power for overclocking. You only need to have the 8 pin power to be connected which can be done with 2x4pin.

Cpu pins I checked is fine...

I’m using only 2x4pins connected to mob

Cheers lads I managed to get it to work,, everything was okay, just had to jump start the mob as I don’t have a case to switch the power on..
