Title: Question about x16-x16 Riser with molex [Solved] Post by: N1CKH0LAS on June 11, 2013, 10:12:59 AM I know what's the purpose of the molex, but if you don't want to connect it for whatever reason, does the x16-x16 riser still work like a non-powered one ?
I mean, have 4 x16-x16 with molex and connect the molex of only 2 of them, while the other two, even if they have a molex connector, you decide not to connect the molex. Would the latter two still work fine ?

Yes, although you might burn out your mobo power connectors if the GPUs are drawing too much current! You might be able to get away with two powered and two unpowered connectors, but it is not advisable.

I was just wondering what happens if you have x16-x16 risers with molex and you just don't connect all of them. I mean, have 4 x16-x16 with molex and connect the molex of only 2 of them, while the other two, even if they have a molex connector, you decide not to connect the molex. Would the latter two still work fine ?

If you have a x16-x16 riser, please disconnect your molex and tell me if it still works fine. Thanks :) Why can't you try it?My answer would be it depends on the card. If the card tries to draw power from the pci-e slot, it would not able to, and might or might not work.

I have 2 7970's and a 7950 running. Title: Re: Question about x16-x16 Riser with molex Post by: N1CKH0LAS on June 12, 2013, 06:38:05 PM Thanks for answer, mate :)
Title: Re: Question about x16-x16 Riser with molex Post by: snowcrashed on June 13, 2013, 03:22:44 AM Do x16-x16 risers even need to be powered? I thought the whole purpose of powered risers was for x1-x16 because the x1 slot on the motherboard does not provide the same amount of power as an x16, thus using a molex to supplement it.

They supply the same amount of power. All the 12v comes from the first couple of pins before the notch. After the notch, all of that is dedicated to data.

I'll change the title to [Solved]
