Not sure how to connect up psu to 6950, help needed pls.

[Abacus]

Hi, just got a new 6950 graphics card which needs/has:

''2x 6pin PCI-E power connectors required (Power Adapters included in box for older PSU's)''

I have an FSP Blue Storm AX500-A power supply, which only has 1 pci-e power cable. As stated above the card came with 2 x (2x4pin molex to one 6pin pci-e) convertor cables. However in the instructions for the card it states that they dont recommend using any convertors at all.

So what I wanted to know pls is:

1) should the 6 pin I have got go into a specific one of the two 'ports' and

2) Can i use the convertor and what risk is there in using them, and what might I lose by not having the 2 6pins?

Any help would be very much appreciated so I can tell if i can install my new card risk free.

Thanks a lot

Thanks very much Surveyor for your quick response

re not using the adaptor, i realised that the card needed the 2 6 pins, i just wasnt sure whether or not i would have to but a new PSU before i installed the card. I take it from your response that it might be a good idea to get a more modern one anyway due to the 12v rail, i just wasn't sure if it was safe to put in the card with my existing PSU until such time that I managed to get a hold of a new PSU. Apologies for all the questions, been a while since I got a new GFX and a bit paranoid about messing it up

Apologies but the sticker you refer to seems to be on the other side of the psu and is not visible without a bit of dismantling. I found this article, would this answer your question (i am not very clued up on this sort of thing as you have prob realised)

''The cross-load characteristics of the PSU are good, but like other units without dedicated voltage regulation it cannot boast an ideal stability of the output voltages. The +12V voltage fluctuates the most, from 11.4 to 12.6V.'' (Quote from within the review)

Hi, once again thanks a lot for your help mate.

At this stage I will be running everything on stock....the jump up from my old graphics card will be more than enough just now I will have a look at getting a more modern and better suited PSU before I try anything.

To be honest I just wanted to make sure i could plug the card into my system and use the power adaptors without causing any harm.

The rest of my system is a few years old as well and i dont have a great deal in it(power consumption wise) so i take it that I will be ok to go ahead and stick it in and look for a new psu in the near future?

Hi Marine-RX179, thanks for the reply buddy.

My spec is
OS Win 7 64bit
CPU AMD PhenomII x4 955 running at stock
MOBO Gigabyte GA-770T-USB3
RAM 4Gb GSkill 12800
HD 2x500Gb
(PSU and Graphics as mentioned above.)

I posted in the general hardware section recently asking for advice on upgrades. The helpful advice i got was that the rest of my system should be ok for now, and the graphics card would make a nice upgrade from my existing 8800gt

I just got nervy when i recieved my card and my PSU didnt have the necessary connectors without using the adaptors, which the graphic card instructions said was a bad idea.

Thanks a lot for putting my mind at ease, I figured given the advice i had previously recieved in here that it wouldn't bottleneck too much, and would allow for upgrading other parts at a later date.

Cheers again for all your help mate

Sorry folks, thought this topic had drifted into the abyss, I stupidly didn't check back to see the additional information you had given. Thank you very much all of you for your help.

As you predicted I did run into trouble, and am now on the lookout for a new PSU, which wasnt in my initial plans, but given all this prob should have been. Thank you once again for all the help, advice and info
