GTX 970 Advice: power/ pin count?

post #1 of 4
Thread Starter 
Oh hi there.
I'm looking at upgrading my R9 270 to a GTX 970 this black friday. For modding reasons I'd prefer a blower style (it'll be Corsair water cooled). I'm looking at a few cards on Newegg:
EVGA (12 pin): http://www.newegg.com/Product/Product.aspx?Item=N82E16814487070
ASUS (8 pin): http://www.newegg.com/Product/Product.aspx?Item=N82E16814121926
Gigabyte (8 pin): http://www.newegg.com/Product/Product.aspx?Item=N82E16814125806
PNY: 1 year warranty, newp

Q: Am I correct in that the greater pin count can theoretically provide a greater amount of power?
QQ: If so, and depending on the quality of the specific card I get, is my overclocking then theoretically better on the EVGA? (It has a higher stock/ boost clock...)

Not something I thought about when building my first computer a year ago. Hoping to make a better purchase this winter smile.gif

Thanks for the advice/ input!

Best,

Joel

Yes and yes

But the difference between the single 8 pin vs 8+6 is minimal. It allows you to reach a higher core OC but the actual gain in performance past ~1450 core is minimal. Most 8 pins will hit 1450 as long as you got good silicon. Never hurts to have extra power to make sure it stays stable though. I just wouldnt get to caught up in it. Just my personal experience with maxwell.

The 6 + 6 vs 8 pin power connectors will deal directly with how much power limit you can run on the cards. With the 970s it's especially important that you pay particular attention to the TDP the card is set to run at. The higher the TDP, the higher the power limit. (see image below). The higher the power limit, it becomes more and more likely that you'll be able to get more clock out of the GPU without hitting the power limit and power throttling the card.

The power pins, however, have absolutely nothing to do with how much voltage is delivered to the GPU core itself.
