R9 290 not outputting display

[TheMail]

Alright, so a friend of mine gave me his R9 290 since he upgraded to a 980ti a little while ago, and I have an interesting issue with it.

When plugging it in it shows as "No cable connected" on my monitor, and I think I might know why, but I'm not sure.

I've tried different 8-pin & 6-pin connectors from my power supply with no avail. I've made sure the card is nested nicely in the PCI express slot.

I've tried flicking the little switch on it for the Legacy & UEFI bios settings with still no avail.

 

What I think it is, is that my power supply doesn't have enough wattage on the main rail.

I have the Corsair CX750, and it has 130W on its main rail, whereas on the minimum specs it lists minimum 150W on the main rail.

 

When booting up, the fans spin on the GPU, so it's getting some power.

 

Oh and also, my current GPU works perfectly fine in the same PCI slot, same cables, etc...

You've switched the monitor to the right input, right?

Have all the drivers installed? and switched over from the intel dedicated graphics right?

if the drivers weren't installed wouldn't it read "No signal" instead of "No cable connected"?

also i leave the tab open, it's fine

Depends on the monitor really, some just say "no cable" to mean the same as "no signal".

What cable are you using?

well ive seen both of those messages display on the same monitor so i assume they have different connotations

im using Dual Link DVI, although I don't have any HDMI or DisplayPort cables on hand
