Graphics card dead?

[squatman]

Hi there,

I have an Alienware X51 with the 330W Power Supply Adapter and a GTX970.

I was led to believe that the PSU wasn’t enough when I was playing demanding games as my monitors kept turning off (fine when not in game) anyway; I purchased a separate case PSU purely for connecting to GPU I linked out the two pins so allow startup. I didn’t get any bangs or pops but my graphics card didn’t start up and I haven’t been able to get it to work since. Does anyone know what could be wrong or anywhere I can send for repair or repair myself?

Thank you.

Case psu? What did you buy? How did you hook it up?

It was a Corsair RM650x.

 

I connected 2x 6 pin connected to the card itself. It was still connected to the Alienware motherboard.

Then I linked two pins on the ATX connecter to enable startup, as detailed here:

Yeeesh 

These OEM PC's have proprietary pin layouts and will most likely not work with an off the shelf PSU

Ok, so has it now damaged the GPU because powering it in the original configuration the GPU doesn’t seem to power up?

I don't want to say you did 

So maybe try the GPU in a different system and see 

You most likely killed the mobo not the gpu

I dunno.  I guess thinking the PSU some how killed the graphics card?

 

But I don't see how that's possible.  The card is getting +12V from the Alienware's PCIe slot and +12V from the RMx.  And while they're different sources, the voltage should be somewhere between the two.

 

Unless, of course, the wrong PCIe cables were used between the RMx and the graphics card.

 

@squatman:  You used only the PCIe cable that came with the RMx and plugged that directly from the RMx to the GTX 970, right?  You didn't use ANY of the existing Alienware power cables for the graphics card, right?

 

If you used that "R1 R2" cable with the RMx, you probably fried your card because the pinout is different from that of the RMx's cable.
