I bought both mobo and gpu last week for an i7-4790k build.  I cant seem to have both mobo and gpu to work together.

I troubleshooted using an old Radeon 6770 gpu with the new mobo and it worked.

I also tried the new gpu with the old mobo and it worked fine as well.

Upgraded the bios to v1.6 already.

So what could be the issues?

What should be the recommended minimum psu wattage if i have both these mibo and gpu?  Currently using a 650W psu.

Thanks.

650W PSU should be enough for single VGA configuration.

Try the other PCI-E slots to see if there is a problem on it.

Already tried using the 2nd pci slot.  Still not working.

What do you mean by not work? What exact name is your psu? You can simply use power supply calculator here but it's just a suggestion.

When turn the Pc on, the screen is just blank.  I'm using Fsp raider 650W.

Keep blank screen until you shut it down or it shuts down itself?

Did what you suggested.

- Single ram.
- No hdd, usb 3, casing connectors.
- cleared CMOS.

Still the same blank screen.  The GPU fans are running btw.


Also, Tried to see if PC will boot using mobo integrated graphics, and it did.
