Chosen Solution

I purchased a replacement power supply for my Gateway GT5404 tower. All the connectors seem to be there except one! I am adding pictures to show the dilemma. The connector I removed from the old power supply is marked “F2”. None of the connectors on the new power supply are marked with any name.

Here is the old P2 connector:

Here is the new 8 contact connector:

Here are the new power sup specs:

Here is the motherboard info (hopefully turned the right way!):

Update (11/24/2022) Thanks to yous guys I’ve got everything all plugged in and ready to go as soon as I dig up a little bit of heat sink paste! Thanks to everybody that got me on the right track!!

What is the make and model of the power supply? There should be a description sheet that came with it. What is the model number of the motherboard? It is usually printed on the board. Could be something like “Intel D945GCLG1”. Might be a good idea to blow the dust off the board. Or do you still have the manual? Printed or on CD perhaps. The 4-pin connector in the photo is like the one for the CPU. Does one of the 4+4 connectors, in the lower left of your photo, fit? The connectors are “keyed” to certain connectors on the mother board so should be fine. Don’t force anything. When you reassemble don’t forget to clean the heat paste off the CPU and heat sink and replace with fresh paste. Don’t use too much. Just a “pea” size squirt will do. The force of the heat clamps will spread it around as you close it. Let us know how it goes and don’t hesitate to ask any more questions.

AH YES, this issue. What a lot of new power supplies do is they have a “8-pin” CPU power connector, but split it 4x4 for legacy motherboards, or 2x6 (it depends on who made it, but you see both). The reason is it’s cheaper for them to do that than it is for them to sell a 8 pin version, but split the connector for legacy boards, but at the same time make it compatible with high end Xeon and Threadripper boards, which need it due to the power these processors draw. While most people will not need it, once these high end boards and processors trickle down the power supplies which have it will be required to use the boards. However, the current Xeon and Threadripper boards already demand this many pins, even today. This connector is not news to those of us who came to know it from the high end secondary market. You see the same thing with the PCIe connector for GPUs; since most GPUs are 8-pin (except the RTX 4000 series with the proprietary 8>12 pin “high power” adapter) but you can split the 2 pins and get a 6-pin connector. You’re going to see this being a need on more and more desktops, as low end CPUs largely go to die because of smartphones and tablets, and the high end chips need A LOT of power to run. I would not be surprised if there will be a point anyone who is building a high end system will have no choice but to use a high wattage (850W+ power supply) to run some of these boards and processors!
