Why does it use power pins

Recommended Posts

Posted · Original PosterOP

My old gtx 980ti used 6 power pins but why does my new rtx 2060S only use 4pins?

Each yellow wire is equal to 12V

It should have 2x6pin or one 8-pin

The official one has one 8-pin 

 

Looks like the ASUS ROG STRIX model has a PWM fan connector on it, that's the cyan line on the right. The yellow line on the right is a RGB connector.

Other third party versions may have different things on them.

The 980 Ti has a 6-pin and an 8-pin, the RTX has one 8-pin. There's nothing weird here.

But why does a 980ti use more pins? Shouldn't it be vis versa

Your new GPU uses less power because it's a x60 Tier, your old GPU uses more power because it was a x80 Ti tier. 

 

There is roughly a 4x performance difference between a 60 and an 80, with a Ti usually having another 20% on top of the 80. Relatively speaking that 980Ti is only 13% less performance than the 2060S.

 

So 8-pin power means it needs 150watts of power. 6-pin power means it needs 75. So when it has 2x6 or 1x8, that means it needs 150 watts, and if it needs 1 1x8 and 1x6 then it needs 225watts. It's entirely possible to see a GPU with 2x8 and 1x6, and pull more than 300 watts. Those aren't typical.

Other than a Titan board, the most power you can reasonable expect is for the RTX 2080 Super, which is 250 watts (1x6 and 1x8).

A 2080 Ti requires 2x8pin

generally technology becomes more energy efficient over time, not less. if I'm not mistaken, the 980ti used like 75w more.
