550 Watt capacity with 38A on a +/- 12 volt rail (connection) for dual graphics configuration such as CrossFire.450 Watt capacity with 30A on a +/- 12 volt rail (connection) for single graphics configuration.Review the power supply specifications.If you encounter suchĭifficulties please review the following information: Peripheral devices may also cause this problem. Sharing the same power connection with other PC Stable. This may be caused by a low power or current drawn into the Owners of a RADEON X1900 series graphics card may encounterĭifficulties installing or getting the graphics card to run The information in this article applies to the following configuration(s): The Diamond card should be similar enough for this info to apply, I think.ħ37-21794: Power Connection on a RADEON X1900 Graphics Card ATI says you'll need at least 30A on the 12V output and maybe more. I tried to make a direct link but that won't work. Check the card's requirements against your power supply's output and try to make sure also about the kind of adapter you need.

If I can't find the answer to powering this baby, I may just send it back before my time runs out and live with my 128 meg ATI Radeon X600 Pro a while longer.Īs Dave said, even if that kind of adapter is the right kind, your power supply might not have enough current output for the voltage(s) used by that extra connection. I don't want to have to lay our $100 or more for a new supply if I don't have to.

That seems weird to me.ĭave, is there any where I can find out whether this is a correct adapter? Is there a site where you could steer me where I can find the correct adapter, if this isn't the one and find out the proper way to connect it? I have a 550 watt power supply which seems it should be ample. The tech told me that one of these connectors is connected to a power source and the other one plugs into my hard drive. I went to a local electronics supply company and picked up what was supposed to be the correct adapter to adapt the 6 pin molex to a standard 4 pin power supply cable (the jpeg attachment is in my first post). As you can see, only three of the four pins are used in the two 4 pin connectors.

The 3.3V has been used exclusively to power PCI slots - while on-board internal regulator usually makes 3.3V for chipset and CPU, it may be too weak for some PCI boards so in early mainboards it is not routed to slots.First, there was no mention of powering the card in the Diamond manual through the card's 6 pin molex connector. Intel Advanced/AS mainboard), the pinout stays the same as shown in the document. Atlantis Socket 5 and similar Socket 7 mainboards). P10 AT aux power supply connector (found on some Dell socket 5, 7 and 8 motherboards). The proprietary 3.3V connector is not only for Dell, but also IBM (especially Power Series) and Intel (e.g.

The two negative rails are bias supplies which only have to provide small amounts of current. That was used primarily to run disk drives, motors, and fans. There are three or four lines dedicated to the 5 volt rail. As a result the PSU delivers most of its wattage at 5 volts. In old PCs, almost all of the chips ran directly off of the 5 volt rail.
