Yea the actual logo on the motherboard , not the bios/splash screen I can't even get it to get to that point lol.
I just got this PSU yesterday brand new from best buy .
I have also checked and double check to make sure the power / reset headers are in the correct pin slots.
Brand-new means nothing... Read my sig.
Are any of the POST LEDs lighting up? If not, could be a bad MOBO.
I would recheck the PWR / RESET / HDD / LED header wiring to eliminate any mistakes there, then remove and jump out the ATX power connector to see if the PSU even comes on. Leave a HDD or something connected, some of these won't do this without a load on them. If you still have trouble, the capacitors in the PSU could be going bad. They are supposed to store voltage for the increased surge load of startup, but if they don't have enough stored, it will stumble and the system will shut down or not even try to power on.
