4pin 2x molex to 8pin convertor - ok on one power cable?

[joe pineapples]

Hi

Got a GTX 280 coming on monday, but only got 2 x 6pin PCI-E connectors on the PSU, so will have to use a 2x molex to 8pin convertor jobbie (hopefully will come with one). But will it be ok to run both molex ends off one power cable? (that also powers a 120m LED low rpm fan) - it would just be a lot less messy that way.

thanks
joe

My PSU only has 2x6 PCI-E too and I'm also awaiting my 280GTX, what connections do I need assuming the card comes without?

All depends how much current each cable off your poer supply will supply. I'd use 2 separate ones personally.

My psu comes with two 8 pin PCI-E connections

If the card comes with a 2 x 6pin to 1x8pin you should use that for the 8 pin

Usually also come with a 2x 4pin molex to 6pin which should be powered from two different molex cables not the same one.

Molex to 8pin graphics connector don't exist. If you are lucky then your card will come with a 2x6pin to 8pin converter and a 2x molex to 6pin converter. If not then you will need to source these from somewhere before you will be able to use the card.

Thanks for the replies. I guess a 2x6 pin --> 1x8pin, and a 2x molex --> 1x6 pin (on seperate power cables)....it is then

My PSU comes with an 8pin + 6 pin (the earlier revisions did not) so I am happy

Whats that then? hmmmmm (pls remember the 8pin is supposed to carry upto 150w of power, each molex needs to be on seperate source from PSU, and hopefully its a good psu with seperate 12v on each source)

With my ATi card, you can use 2 x 6pin, if you want Overdrive, you need 1 x 8pin, or mod it so that the 2 spare pins get good ground, google it, easily done.
Unsure on NV products though, it might force to have 8 pin.

By chance is it an OCZ stealth job?

I have seemingly and older revision of the PSU and only have 2x6pins, the newer has 1x6 + 1x8.

The 2 extra pins are both earths, all you have to do is loop over from the other earths and it will work as intended.

I'm using this solution, and it works superbly:
