GTX 280 - 8 pin and 6 pin power - adapters good enough?

[gramboh]

Hi,

I've got a Corsair 520HX PSU and am thinking of upgrading from the 8800GTS 640 to the GTX 280.

I know the GTX 280 needs one 8 pin and one 6 pin PCI-e power cable. My 520HX has two 6 pin PCI-e adapters. On the NCIX website, it says the eVGA card comes with an adapter that takes two 6 pin adapters and makes one 8 pin adapter.

My question is, since I will need both my 6 pin PCI-e adapters for the 8 pin, can I use two molex adapters to make a 6 pin PCI-e? Is this going to provide enough steady power? I really don't want to upgrade my PSU.

Thanks

I just realized the 6 pin PCI-e cables have an extra 2 pin adapter with them, which would make them 8 pin total. Is anyone using this setup? Or with a 620HX? Just want to be sure before I get the card.

Thanks

Yes, I'm using this arrangement and it works fine.

If you have the extra 2-pin slideout piece on your PSU though, that provides a true 8-pin connection. You don't need to bother with any adapters in that case.

that's called a 6+2 pin adapter. I didn't know that my 620hx had them until I read a post by yellowbeard 5-6 months ago about them.

by the way, anybody with an hx 520 or hx 620 who does NOT have the 6+2 pin adapters, if you need them just send a pm to yellowbeard with your request. all corsair does is charge you a small fee to ship the cables.

Thanks for the info, I'm not 100% sure if my 520HX has them or not, I bought it in March 2007. I'll check tomorrow and if not I'll PM yellowbeard.

Cheers

My HX520W has an 8pin (fixed, ie you can't make a 6 pin out of it) and a 6 pin. Problem was I had to use 2 6 pin plugs for my 4870. I bought a 2-white-power-plugs -> one-6-pin-plug thingie and so far it works Didn't know I could call Corsair for that. Does it also cover europe (denmark) ? I think I'd rather get a regular second 6 pin cable (there's a free plug on the PSU).

Yeah. Actually my Corsair hx520 did not come with the 8 pin at all no 8 pin or 6+2. So I just called Corsair and they sent me an adapter for FREE, no shipping charges or anything, just told them my name, serial number, address, etc. I must say I was impressed by it
