GTX 650 Ti Boost DCU-OC2, can it run without 6-Pin power cable?

[Achint2000]

I have Cooler Master Thunder 300W PSU and I want to run my GTX 650 Ti Boost DCU-OC2 on it but the PSU doesn't have the 6-Pin power adapters. Will the GPU run fine without the 6-Pin cable or games will get slowdown?

~Thanks.

This card requires that power to even run my friend. I'd suggest a 500W.

Nope, I just want to know.... Okay. What will happen if I start my PC without the 6 Pin power plugged into the GPU? Blank screen?

Yes the GPU won't be powered it would be like unplugging your PC and hitting the power button.
