EVGA Power boost?
-
I’ve seen these before…
It’s 1 slot per card and then an additional slot for the power card you have dropped a link to.
Now that said, there is a lot of discussion as to cutting the cables on powered risers to protect the MoBo from over current being dragged from a powered slot to a non powered slot thru the board. It’s fair to say that if you connected this you may end up doing just that as all the addition peer come from 1 slot on the board.
I’m no electronics engineer so could very well be wrong. Might solve the short term problems but as to the long term gains… no idea

The reason Sheepson is posting this, is because the mobo of our mining rig has a melted 24 Pin molex:

[/quote]It is probably because there is too much power going trough the motherboard, so that’s why we were thinking about buying this PCI bus power thingy :).
The psu / motherboard still works tho! Now running with 3 x 6970.

Evga power boost can help both with running unpowered risers and keep you from melting the 24pin connectors. It will provide extra power to ALL of your PCI-E slots at the same time and only needs one slot for itself. I would not run more than 3-4 GPUs on one machine without some sort of extra power going to the PCI-E slots (powered risers, power boost, or extra on board PCI-E power connections). Powered risers only feed one card at a time but this will distribute the extra power to every card in your setup and increase stability. I have seen these used to stabilize power hungry overclocks on GPUs when benchmarking, if you are having any stability problems take a look into getting one of these.

Cards immersed in oil can support more power ?? :-\
sparks and arcs are attenuated ?? ???

It’s only supposed to be used on sli and crossfire configurations. The idea is that by using crossfire or sli you are putting strain on the 24pin connector, and this will affect the lifespan of the board. By adding the “power boost” card you are supplying more power to the pci-e slots straight from the power supply thus putting less strain on the 24 pin connector. If you’re running a crossfire or sli configuration this would be a good investment.

If I ever run sli or cross fire I will get it

OK so I can see how this moves the power from the 24 pin connector, but surely all your doing is moving it from there to the bus connectors?
Again I say I’m no electronics engineer but I would have thought the 24 pin connector had the largest tracks thou the the MoBo as that’s where they are designed to get the power from, not to start dragging it from another PCIe socket.
I’m struggling to find an analogy to use to put this into perspective at the moment, but can fully understand how powered risers (we are all calling them that but is that what they really are?) with the cables back to the board will help as the only place the power can be draw from is the PSU and the only place it can go is to the card plugged into the “riser” but these seam to me like all your going to do is move the power problems from one place to another, and where your moving it to is the tiny tracks of copper printed on your MoBo which can’t be a good thing!
I need to do a little more research on it I must admit, but for me right now these devices are defiantly a no.
