Nvidia 9800 GTX+ Power?

Hey guys,
I'm new here and have a question.
I recently bought a 9800 gtx+ (512mb) graphics card, but it didn't come with the power cable, 1 x 4 pin periphal cable -> 2 x 6 pin PCIe power cable. I ordered the power cable but got sent the wrong thing, it is only 1 x 6 pin but has 2 x 4 pin periphal cable. I tried using this cable and it seems to work OK but I want an opinion on whether it is a good idea or not.
Cheers and peace out.

BTW my system specs:
E7500 2.93GHz dual core CPU
480W PSU (20A)
4GB DDR2 RAM (2x2GB sticks)
Nvidia GeForce 9800GTX+ 512mb graphics card (PCIe)
MCP73VT-PM Mobo (Getting Gigabyte GA-P43-ES3G mobo later today)

Huh? Thats the cable you need. What would you do with a single 4pin molex to dual 6pin PCIe?

If your card needs two of those 6pin plugs then I suggest you get a newer/better PSU. You'll stress the $h!7 out of the one you have, and who knows what will happen when it blows.

The graphics card has 2 of the 6 pin plugs...
The PSU is brand new and can handle the power that the graphics card needs, I just need to know if my graphics card will be alright with only 1 6 plug plugged in.

You should plug the other one in. The recommended PSU size for your card is 450Watt with 24amps on the combined +12 volt rail.
Do you mind sharing with us the brand and model number of your brand new PSU that comes without 6pin PCIe connectors.

How do you know?

And if it did have 2 PCIe power connectors, a 9800 GTX+ needs about 11 amps and your CPU will need about 7 amps if you do not overclock it. Add drives and fans and with a 20 amp single rail PSU, your 12 volt rail will be running close to 100% capacity.

Not a good idea. :pfff:

Just checked the PSU, it's 480W with 30A not 20 >.<
The connector seems to be OK for it after testing.... Will have to see how it goes.
Sorry for being such a noob :lol:
