I'm trying to install a GeForce GTX 460. It came with a supplemental power supply cord, one end goes into the card, and there are 2 heads on the other end, and i can only find 1 place to plug in a single head into my power supply... When i turn the computer on the fan on the card turns on so i assume enough power is being given to the card, yet when i log in and put in the Installation disk, it says quot;not foundquot;... i already locked the card in, and i tried re adjusting the card multiple times but that doesn't do anything so i'm sure putting in the card incorrectly isn't the case. help! :(
If your power supply doesn't have a single PCIe Power Connector or 2 standard MOLEX(4pin) connectors to attach the adapter to I'm sure your way under powering your card. especially if your computer isn't a gaming rig or self built it probably only came with nearly the minimum power supply needed for the OEM parts already installed.
You are taking a chance of burning up your PSU and your card. The card might perform ok under basic desktop situations, but when you try to game it is going to drain your PSU for all the power it can get and probally fry the +3Volt rail that the single molex connector is on that you pluged the PCIEx16 6pin pigtail up to. This might even cause a short of your motherboard and or ram on the motherboard, and could even lead to a frying of the CPU as well. Or maybe not, just a chance you are taking...
If your power supply doesn't have a PCIe power connecter then it is almost certainly not powerful enough to run the card. You need a better power supply. Next time read the requirements for the video card and make sure you know what it's saying. Did you even plug your monitor into the card after installing it? I said that if your POWER SUPPLY does not have a PCIe plug, then it's almost certainly not powerful enough to run that card. Adapters mean squat.
