How to connect external power to graphic card

Your Graphics card should have 2-6 Pin Power connections located on the Top Rear of the card. You would need to use an 8 pin to Dual 6-pin adapter cable for the Graphics Card.

Howe to connect the power cabel to my new graphic card

Firstly, you need to have a power supply that meets the power (Watts) and current (Amps) of your card. Check your video card's documentation to verify this, and look for a sticker on your power supply to give you more information about your power supply's Wattage and Amperage ratings.
Next, if your video card needs additional power (it will have a molex 4 pin (like a floppy drive uses), or a 4 or 6 pin PCI Express Power plug. In case your power supply does not provide you with this type of power connector, many video cards include a 4 pin Molex to PCIE adapter. Again, make sure you meet the power requirements for your card, or it will likely die prematurely due to under-current conditions.
If you are using an adapter, plug a hard drive or CD-ROM drive power connector in on one side and to the video card on the other.
IF your power supply provides the correct power connector, use that one side goes to the power supply, and the other to the video card.
(It's less hinky that way, and I think it gets it off the same circuit with the other devices.
Good Luck!

Hello there,
In Windows, it just comes up with a message saying it will be clocked down, so you just click "OK"? if molex is not plugged.

1. You should install the driver for the graphic card so it wont show distorted images, Microsoft display drivers are not reliable in gaming you may experience distortions.
2. Plug the molex or 4pin power to your card and observe if you will encounter the same problem after doing step 1.
3. If not try to test another PSU or acquire a new PSU that is powerful enough to run the card - not using the power cable could damage all your system.

Hopefully this information helps.
Happy Gaming
Thank you for using FixYa.

Hi - I believe you might be suffering from one of two (or even both) problems. The video card sucks lots of power and I believe has a separate power connector on the card that should be connected. The type of connector varies with manufacturers; from a four pin floppy disc type to a molex type connector or even something proprietary.
Secondly -- It's recommended that you have a 350 watt or higher power supply in your system.
Either issue could keep your machine from booting.
Good Luck, Mikeywaf

You can but a molex splitter so that you can plug the single molex you have into it and then have two, like a "Y". You will probably have to go online to a company like,, or who sell power supplys. I realize that means waiting a few days but the alternative is to either modify your PSU which voids the warranty or buy a different one. The splitter is inexpensive.

Burnt out 3 diodes..what are they?

look man that molex connector is providing the mass of the power that board uses w/o that i would think it'd be hard to fry anything unless the board was already screwed :( i think replacing them only to watch it happen again would be no fun :(

X1650 xt agp installation problem

check and see if your pc has the recommended power requirements, a lot of the generic power supply's can't support anywhere near the posted wattage. A good power supply is very heavy with big heat sinks. Also check and make sure that the graphics card does not require any extra power connectors. A lot of the newer card require you to either plug in a pci-e power connector, molex plug, or floppy drive power cable.

Xfx 7950gt agp 512mb

Hi, if you have got the drivers for this v/card then load them while you have your present one in place, if you dont have the drivers then go to the manufacturers website and get them . when you have loaded the drivers then check if you need to enable any changes in your bios. Change the card and if it is functional then you should have solved your problem. A card that advanced needs drivers far greater than you would find in XP. Regards mistyman
