Graphics card

[Zeeb Shadosworn]

Hi there
basically I brought a graphics card, (its a GIGABYTE Radeon R9 380X), and turns out my power supply didnt have the 8 pin cord for it. So i used a 6 pin to 8 pin adapter but it still wont work and the screen wont even pick up anything from my computer (I tried HDMI and DVI from both my pc and graphics card to my screen). So does anyone know what's wrong? I've been told I need to buy a new pwr supply but I dont have the money for that right now so is it possible to get the card working some other way? btw my pwr supply model number is GE-C420A-C2
I'd apreciate any help
Cheers

Is that PSU rated at 420 watts?
That should be enough unless you have other stuff that drags down the power.
Maybe this link has the answer.

It seems people can not get a good answer and maybe yu will have to go get a better PSU.

ye so the psu is 420W (peak load)

The 6 pin  pin adapter is the recommended type. - Right?
Let's suppose that is not the problem.
Here is published data.
Radeon R9 380
Idle = 75 watts
Full = 290 watts
The X model is almost the same.
So yes, you will need more power to have margin of reliable performance
Still, you would think t the card would at least start up.
But you say the card does not even show anything at all?
Maybe there is some kind of problem.

When you first turn on  a motherboard, the BIOS can run on either the built-in or the new graphics card. There might be a setting inside the BIOS setup that has to be set. Look in yu manual for the motherboard.

Does the manual indicate  you must disable the built-in video?
This is about fas  as I can help.

Maybe somebody else can.

The 8-pin connector is required.After all, if it could use a 6-pin it would be a 6-pin connector. It will not boot without it connected.

That PSU is also nowhere near being capable of running the card, which is probably why the PSU lacks an 8-pin connector.

Yeah when I turn it on the screen just gets no signal, the card does light up but the fans don't start.
Thanks a lot for all the help though Geek-9pm and BC_programmer
