Brand New PC not starting

[Greatchap]

Hello Everyone,

 

I wanted a new desktop pc for myself so I bought the following components :

 

-Intel i7 14700K

-Gigabyte Z790 UD AC Motherboard

- WD Black SN770 M2 NVME 2 TB SSD

- MSI MAG A750GL 750 WATT PSU

- Deepcool AK620 CPU Cooler

- Deepcool CH560 Atx Mid Tower Cabinet

 

I assembled the components and then when I tried to turn on my pc nothing happens. No sound, no light nothing. All the components mentioned above are brand new.

 

What to do ?

 

Regards,

GR

find the motherbaord manual, find the 2 power switch pins, short them with a screwdriver. Also is your power supply turned on? Do you have a graphics card? Check power connectors. Check all connectors in fact. Does the psu fan spin?

Thank you guys for your help.

 

The PC/System has started successfully. A small connector along with main 20 pin connector was not connected. The big connector was connected but the small one along with it was not.
