Power for MSI GeForce GTX 1070

[Kantertainment]

Hey guys,

I have the Be Quit! Dark Power Pro as power supply. Where do I plug in the power cable for the MSI GeForce GTX 1070?

Is it PCIe1, 2, 3 or 4?

Here is how it looks:

Any of them will work doesn't matter.

 

[xapoc]

PCIe 3 & 4 puts out 35 amps, use those instead
PCie 1 & 2 puts out 30 amps
Assuming you have 850w PSU. But seems like they all put out more amps on the 3 & 4

It's a 550W...

 

[xapoc]

+12V1 (A)20
+12V2 (A)20

+12V3 (A)25
+12V4 (A)25


So switch to PCIe 3 or 4.

Dont pay much attention to any of the amps and stuff its a good Power supply any of those slots will work fine and 550W is just fine unless you have 2 graphics cards.

That's completely wrong.

The PCIe power sockets on that PSU are only wired to either the +12V3 or the +12V4 rails.

+12V2 is strictly dedicated to the CPU power connectors.

+12V1 is wired to the motherboard ATX 24-pin connector and peripheral power connectors.

It really doesn't matter which PCIe sockets on the PSU are used to power the graphics card.

So it doesn't matter where I plug in the 1070?

It would have been different if PSU put out lower current than recommended power per 12v rail.
requirement for GTX 1070 is 30amps, I brought connector 3 & 4 up for a reason and its obvious.

Correct.

An MSI GTX 1070 Gaming X 8 GB graphics card itself draws at most 16 Amps peak.
