Graphics cards that need power supply

[HazeXL]

so, untill recently I had never had a video card that had a plug for power ON the video card itself, and I could never find out where I needed to plug it, I'm guessing into my power supply, but my power supply doesn't have a plug that supports the 6pin connector.
My question is, do I need to upgrade my power supply or is there something I'm missing?

Depends. What kind of video card is it? also what kind/how many watts is you Power Supply?

If your psu is good enough, than you can just get an adapter which will use 2 molex plugs from your psu and convert it to the 6 pin for your video card.

my power supply is 550w and the card requires 450w, so I should be good there, although my power supply is some generic piece that came with my case I got for when I built my computer. The video card is Newegg.com - ZOTAC ZT-20109-10P GeForce GTS 250 1GB 256-bit DDR3 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

You shoulod have gotten the adapter with the card. It's the 2 flat 4 pin plugs that cchange to a 6 pin.

no, it didn't come with that. I got a plug that was supposed to do that but the plug didn't fit into my vid card. but if there's another plug that would work I'm interested.

It should fit......But anyway, you can buy these anywhere for a few bucks.

Newegg.com - 6 pin molex

which one? Newegg.com - LOGISYS AD201 12v Molex to 12V 6Pin Adapter I'm guessing?

I see what's going on now, the video card uses an 8-pin pci-e. While the adaptor you got with it converts two 6-pin pci-e to one 8 pin pci-e.

So, what you really need is an adaptor that converts two molex 4-pin to a 8-pin pci-e.

Before you go ordering the cable, could you check the lable on your psu and tell us on many amps is on the 12volt rail of the psu. Even though you have 550 watts, the amps might not be good enough as you say it's a generic psu.

Just don't want you to waste your time and money ordering this cable when you might actually need a new psu to power it.

Hmm, yha i think you have the only model of gts 250 thats an 8pin.

I think you'll be fine still, despited just enough. My q6600 and 260sli only drew 520W
