Hi guys. yesterday i had build a new budget PC with AMD A10 6800k and ASrock extreme 6 mobo. i followed every step on the book and completed my build but when i turned ON the UPS automatically the LEDs and Fans started turning ON and OFF untill i turned off the UPS. then again when i tried to turn it ON it did not start.
Thank you guys for introducing me to the checklist.
What i did was removed all the parts with mobo and installed everything outside cabinet on the mobo box (breadboarding). there i found out the 4+4 pin connector was loose and was not connected properly, may be because of heat sink. connecting that socket solved my problem.
