1) I have a quadro fx 3500 card it has a 6 pin & 3 pin male can it connect to 4 pin female power supply?

2) I only have one space left on my power supply & 2 connections from the card how do I get a 2nd or is 1 connection to the power plugs sufficant?

How about posting the brand name of the card plus the make/model/wattage of your power supply? Did you try reading the manual for the card to see what the connectors are for? A 3-pin male is usually for a cooling fan. If you connect power to it, you'll likely damage the card.

I looked for info about Quadro FX 3500 cards and found no manuals, except for Quadro models FX 3700 and higher (see below)

The card requires a recommended 350 watt capacity or higher power supply .

Are you by any chance trying to get this card to work in a system that has a power supply with a lot less than 350 watts capacity ?

There is a black plastic shrouded connector at the back of the card.

You can see 3 pins going into it from the board. It could also have 3 more pins directly below those, so, 6 total.

It's probably a socket for a standard 6 pin PCI-E connector, in which case, if the power supply has a PCI-E 6 pin connector, you would plug that into it . If the PS doesn't have that 6 pin connector you need to use a wiring adapter with the socket.

It does NOT mention FX 3500, but it mentions FX 3700 which is probably similar.

It shows what the 6 pin to molex connectors wiring adapter looks like when plugged into the black socket.

Do you have one of those ?

If you don't, it's probably a standard PCI-E 6 pin connector on one end, two molex (male pins) connectors on the other end.

e.g.
http://www.newegg.com/Product/Produ...

The PCI-E socket / your graphics card does not require extra +5 v power, so the molex connectors often have only 3 (male) pins and no red (+5 v) wire.

If you DO have one of those,
- you could try the card connected to only one larger molex connector from the PS to see what happens. If you connect only one monitor to the card that may work fine.

- if you have problems when only one larger molex is connected, buy a standard Y wiring adapter - two larger female molex on one end (the metal ends on the wires are female) , one larger male molex on the other end (the metal ends on the wires are male)

e.g.
http://www.newegg.com/Product/Produ...

and use that with your drives - they don't need much power (current) - to free up one more spare larger molex connector for the PCI-E 6 pin to two molex connector wiring adapter - that WILL work fine with the card, for sure.
.....

I have no idea what the other 3 pin connector is you're talking about - it's NOT for power, unless you're talking about the molex connectors on the PCI-E to two molex connevtor wiring adapter having 3 pins instead of 4, which is common..
The PCI-E socket / your graphics card does not require extra +5 v power, so the molex connectors often have only 3 (male) pins and no red (+5 v) wire.

The fan on the cards I've looked at have 2 pin connectors on a 2 pin header on the card, not 3 / 3.

I bought a used pny quadro fx fx 3500, it came with a connection with 6 pin on the side connected to the graphic card.on the other side it has to 3 pin (3 male & 1 empty hole).

My Power Supply is 500 watt EZ Cool ATX-500, socket 775. My Motherboard is a Gigabyte "GS31M-GS" with a quad 9550, XP, & 5 Gig Ram

Could this other connector be an audio connector? Some video cards, especially ones having HDMI outputs have a digital audio input for the HDMI combined output.

You have to be a little bit crazy to keep you from going insane.

Thank you

I realizied that my 500 watt power supply is a P4 ATX so it is the right cable that came with the card (3 male and 1 empty to connect to my Power Supply)

"it came with a connection with 6 pin on the side connected to the graphic card.on the other side it has to 3 pin (3 male & 1 empty hole). "

Read response 2 !!!

The PCI-E 6 pin to molex wiriing adapter only needs three out of the four pins in the molex connector.
The two molex connectors rather than one are required to fully support the same max amperage specs as a PCI-E 6 pin connector that's connected directly to the power supply.

If your PCI-E 6 pin to molex wiring adapter came with the card ORIGINALLY and has only one molex connector (3 male pins) rather than two of them, that should work fine with one molex connector (4 female pins) from the power supply.

If your PCI-E 6 pin to molex wiring adapter DID NOT come with the card, or if you're not sure whether it did, if the card doesn't work properly connected to the one molex connector from the PS, you need to get a standard one that has two molex connectors (male pins) , and the one molex (male pins) to two molex (female pins) Y wiring adapter.
