Hi there,

I have recently bought an XFX GeForce 8800 GS and am trying to fit it. It came with a molex to pci-express adapter, like the one pictured here http://www.atxpowersupplies.com/imag...er-350x350.gif , but the graphics card also came with a warning card saying "XFX does not support the use of 4-pin to 6-pin power cable converters for these graphics cards. They are designed to work with high performance power supplies with 6-pin PCI Express power connectors."

My power supply doesn't have any power connectors I don't recognise, they're all the normal white bulky ones, although I don't know what a PCI-E power connector looks like (sorry I've only recently returned to PC building and am a bit clueless about the latest technologies)

Surely if they didn't want me to use the molex to pci-e adapter they wouldn't have supplied it in the box? So my question is, will using it damage my graphics card?

Many thanks

I have the similar Vcard and I'm using the one same as they supplied you and it works fine.

Guess the best thing sometimes is to not read the cover themselves clauses

They're just covering themselves so people don't use the adapter with a low quality, low wattage power supply. So the important question is what power supply do you have and what is the wattage and current on the 12 Volt rail? There should be a sticker on the power supply with all that info, please post it here.

As T6 posted they are trying to cover themselves. New power supplies are made to a standard where a separate rail powers different items ie cpu, drives, etc. The 6pin video power connector[s] is/are also part of this standard.
When you use the adapter, you do not really known what rail is powering your gpu or how it is shared with other devices. It may or may not have adequate amps.

If your psu is judged ok with enough power, you can buy the converter for your 4 pin plugs and they work fine:

Thanks for the replies,
The cover on the sticker means nothing to me, so I've copied it all down:


Win Power ATX-400

Max power output 400W

Input:

115 VAC, 7A MAX, 60 Hz, 230 VAC, 4A MAX, 50 Hx

Output:

+12V 18A MAX
+5V 25A MAX
+3.3V 18A MAX
-12V 0.3A MAX
-5v/SR3 2.0A MAX

You need a new power supply. 18amp on a single 12V rail is just not going to work with that card.
To be accurate, you would need to post your exact system specs; ie what board, cpu, amount of ram, number of drives, etc however I would be looking for a min of 40amp on a combined 12V rail. Here is a link to a pw supply that would most likely do the job for you.
FSP 550W Note the combined amp on the 12V rail is 60.
