So after assembling everything together and flashing to latest BIOS(version 1805 for Windows 8 64bit) and reading the manual carefully along with watching a tutorial, I finally get to powering on the PSU.

However, even though the motherboards green power led was on, nothing else was. This includes the CPU Fan(which i checked for blocking or tangling and made sure the CPU power was connected) RAM Led, the speaker for beeping signals, a blank screen or literally anything.

I think it's important to note that I am booting without any storage device connected as I am waiting for my shipment of an SSD and a HDD this week. But I heard you are able to do that and still see the UEFI Bios screen.

Also I am not using a video card, instead I am using the onboard graphics from my CPU by connecting the HDMI cable to my tv(not monitor) This is my first build however looking up my situation turns up people with similar issues. Many got their problem solved by using a GPU and not onboard graphics. My problem is though, my CPU fan isn't even on. I've also checked the RAM and tried different configurations.


My setup:

i7-3770k

Asus Sabertooth Z77

Corsair TX750M PSU

Corsair Vengeance 8 GB(2 x4GB ) DDR3 1600 MHz

Motherboard->HDMI->TV(tried multiple)

Also this is all setup with the mobo on my box. Anyway, does this sound like an RMA situation? Hope not

Hi, Make sure you've connected the 8-pin power cable.
If still the same, test the power supply: http://www.youtube.com/watch?v=5FWXgQSokF4 . Connect a fan to one of the psu molex connectors too.

Thanks for the reply guys. Iv'e tried almost everything except the CMOS. I've read not to mess with this though. I could see how the BIOS update(usb flashback) I did could somehow render the igpu useless but how does this still not power my CPU or fans?

Solved it, it was a faulty power supply!
