Zotac GTX1070 AMP Extreme and a HPZ800 with 6 pin connectors

[IIBit]

Hi everyone,

I have purchased a Zotac GTX1070 AMP Extreme after my Quadro5000 kicked the bucket.

As you might have read from the title, I have only two 6pin connectors from my PSU. As luck would have it, the Zotac card came with two adapter cables (2x 6pins to 1x 8pins). I want to know if I should connect my two remaining 6pin psu cables to the 2 adapters ( and leave one 6pin orphaned ), or should I go another way?

I have checked my PSU and it have 1250 Watt output, so I'm good in that department ( I think ), but is safe to use these adapters?

If your 6-pin cables are fully wired (3 colored wires and 3 black wires) they are safe for 150W. Using an adapter is fine. But that still leaves one of the card's 8-pin header unpopulated, doesn't it?

Btw... If your 1250W PSU only has 2 x 6-pin cables, it must be old, low quality, or designed for a server/workstation that normally doesn't have the +12V rail capacity. Can you see the nameplate on the PSU?

Hey,

Thanks for the reply. I think I've gotten everything to work, but I've taken two pictures, just to make sure I don't get any nasty suprises later on. There is one picture of the PSU nameplate, and one of the 1070 connected with the two adapters.

According to this review: http://hothardware.com/reviews/zotac-geforce-gtx-1070-amp-extreme-review?page=6
...the entire system using that card demanded 277W measured at the wall socket. Since each fully wired 6-pin cable has a 150W capacity when used with the 8-pin adapter*, that allows for more than enough capacity to run that card. That, and the fact that each +12V rail is rated for 18A and comes off a separate rail. (+12VG1, +12VG2)

Feel the wires on the 6-pin side of the connection occasionally when gaming. If they are not hot, you are fine. That PSU (while powerful enough) is not wired with the thought of a high end gaming card being used.

Does that system have any free Molex connectors available?


* the extra two pins on the 8-pin are merely redundant grounds for stability.
