Will the GTX 1080 work with my current setup?

Recommended Posts

I currently have an EVGA GTX 680 FTW+ Edition, but I'm not sure if the EVGA GTX 1080 FTW will work with my PSU.

 

MY PSU PCI-e has 4 x 6+2-Pin, and on the 1080 it has 2 x 8pin.

 

I'm not sure how my current GTX 680 is connected, it's been awhile since I last checked.

GTX 1080 and 1070 cards have one 8 pin power connector.  The GTX 1060 has one 6 pin connector.  Click here for a picture and click here and scroll down for the 10 series specs.

 

Each one of your PSU 6+2 cables equal 8 pins.

 

You should be fine.

I hope so, but when looking at pictures, I see that the EVGA GTX 1080 FTW has 2 x 8pin connectors.

 Those 6+2=8... they'll work just fine.

6+2 pin PCIe connector IS an eight pin. It's separated into two parts, a 6 pin and 2 pin connector. You just position the two adjacent to each other to form 8 pin and insert.

 

Non reference cards like the EVGA card you mention will usually have greater power requirements. Thus the two 8 pin, which you already have in terms of two 6+2 pin cables.

 

More importantly, wattage and amps on the 12 volt rail/rails is the factor to consider... the lads are correct re the 1080 having lower power requirements, but still check the wattage required and amps required, because this is a non-reference card you are talking about, with higher power demands.

Some GTX 1080's has more than one 8-pin connector. So look around first and find one with single 8-pin connector. Some cards require more than one 8-pin connector to reach a better overclock, but take the Gigabyte GTX 1080 only requires a single 8-pin connector and it is still a beast.

You are correct.  

 

But you have four 8 pin connectors on your PSU so again pertaining to connectors you should be fine.  You did not say the wattage of your PSU so you will need to take that into consideration also.

My PSU is 750watts, hopefully that should be enough for overclocking

My Zotac 1070 amp edition requires 2 x 8 pin connectors

Amps on the 12 volt rail, or rails if it's a multi-rail?

My Gainward GTX 1070 got a single 8-pin connector.

I think 45?

 

 

No issue then. I reckon 32 amps required. Might be wrong.

Well since my card has 2x 8pin connectors, do I need to use both or only one?

If your card has two, you use two. An 8 pin (or 6+2) PCIe cable into each. Thats why your card manufacturer put them on the card, because the card needs the power.
