New build pc not booting

Hi
My grandson has just built his first PC, unfortunately it doesn’t work....nothing displays on the monitor, not even the Post messages....the monitor works ok on a different PC has been tried with the HDMI and VGA ports.

the Mobo lights up and the cpu fan runs. I downloaded and checked the Mobo manual and can see only one direct power connection, I.e. the 24 pin strip.....is this the only connection, or maybe he has the wrong PSU...

ned some help please..

ASUS b250m plus. and the psu is a 450w corsair


The mobo has an EPU socket which currently has nothing plugged into it ???
thanks

ASUS....
This is a long shot... Look at lights behind memory slot and check which one is the last to light...

Check this first: take out RAM and put only one back. Press it down firmly on both sides of the stick - not one side and then other, or you can like this, but one side doesn't have holder...

Oh, just saw that last sentence.. empty socket? Can you post a picture? Think this is CPU power connector.

Described as an EPU socket I believe, my grandson says the Corsair PSU does not have a plug for this

Yeah, it's the CPU power supply Maybe Corsair have 8 pin instead of four. Half of it should be detachable..

The PSU has a 6 way and a two way marked pcie express, look like the same size but do not separate so couldn’t be used anyway..

i thought ATX PSU’s were standard......think he is going to return and order a different one....

look closely.. they can be separated at the mid. And plug is designed so, you can't stick it in wrongly (rounded)

Have this picture of the 6 + 2 but. Suspect these Are PCI express plugs or am I wrong ?


Thanks have seh

Tell him to check exact PSU model. There should be manuals on Corsair's site.

This is a bit embarrassing.....spoke to my grandson this morning and he said yes he does have an 8 pin plug with CPU on the side, but ignored it as he needed a 4 pin......I said several times that I had the same and it splits, but kids today just don’t seem to listen.....so frustrating


so thanks for all your help.....on my advice he is going to change it for a 500 or 600W PSU, I said that 450W will most likely not be enough if he installs a graphic card later.......

thanks
