EVGA Intros Power Boost Gadget to Improve PCI-E Power Stability

They didn't give the board more connectors because they followed power spec. Not that EVGA is totally free of blame in this but IMO they shouldn't be held accountable for nvidia and ati making cards that draw to much power and fry boards.

As for the price I'm sure once you factor in the labor to make these, costs for making them, free shipping, and all the other costs associated with making these adapters they are close to the break even point.

Did evga expect people to use four 4/5/6450s in crossfire?

Apparently, some ATI cards drew too much from the slots, which was causing problems with the 24pin connector overheating.

I don't know. Doesn't seem to me this has a very big niche to fill.

Wile E said:
Ok, so that begs the question: Why didn't they give the board more power connectors for the PCIe slots to begin with? I mean, they had to know 4 heavily OCed cards might overdraw on the slots.

This is one of those things where I see the point, but at the same time, feel we probably shouldn't need to resort to this.

And the price is retarded.

so my comment about helping to compensate for multi railed PSU's has been ignored/discredited?

so evga goes over spec for like every overclocker related feature and is not responsible for slacking on the pci-e power front?

who would you blame if evga sold you an enthusiast board with a bios that has no fsb adjustments ? (we followed the spec). you can buy a new bios for $69.99 to unlock fsb increases.

The thing is that this is happening on systems that are not massively overclocked on ln2 or dice. Or even quadfire or tri SLI setups. The cards are so massively over spec that they are melting plastic on the 24pins. If this only happened when you were running some extreme overclocking scenarios I would say EVGA is at fault since that is what this board is designed for.

It has nothing to do with the cards being over specced. The problem can happen on cards that are within spec as well.

You pop 4 cards in a motherboard that pull 75w a piece though the PCI-E slot and that is 300w through the two 12v wires on the 24-pin connector. I don't believe that connecter was ever specced for that much power, or really any more power than a single PCI-E slot would draw.

thats correct. just because a motherboard has 7 PCI-E slots doesnt mean they ever intended you to run 7 video cards, especially not 24/7 like some folders do.

adding in a few extra wires to even the load COULD help, but that doesnt mean i think this little doodad is the way to achieve that.

The ATX 24-pin connector has 2x 12V with 16 or 18 AWG. A 5.25" Molex type connector adds one more 16/18 AWG wire.

So the current through the ATX power connector 12V lines is reduced by 33%.

Exactly, that is actually a pretty big difference. Instead of 150w per wire, it is now 100w per wire. That could easily be the difference between melting the insulation/frying the connector and not.

This has nothing to do with multi rail psus. Multi rail psus do not need any form of compensation.

it could help split the load up.

No need. Buy a quality psu, and it doesn't matter at all.

while i agree with wile, i'm just reaching for situations this MIGHT be useful

Multi rail PSUs are just single rail PSUs with multiple OCP circuits. So the only thing this device would help would be preventing the OCP circuit connected to the 24-pin from tripping and shutting down the PSU if it was overloaded. Though a lot of PSUs have the 24-pin and molex connectors sharing the same OCP circuit anyway...

yeah exactly, it COULD help prevent that exact scenario.

you're right on molex and 24 pin often sharing a rail, but its not always the case.
