Hmmm.... mainly you have:
-20 or 24-pins connector, that is unique and goes directly to motherboard (powers motherboard and its components)
-4 or 8-pins connector that powers CPU
-the rest would be connectors for ROM (CD/DVD/BlueRay) and HDD devices (there are: molex and sata power conectors)

If you totaly unshure, there is manual:

New PSU doesn't have four point connection

You can still use this power supply but you will need to purchase a 4 to 8 pin connector . you can find them on ebay etc. You can also use two power supplies, one for gfx card one for PC. I use two. To turn on a PSU without it connected to PC ( just to use it as extra power.) You just have to connect the green wire to any black wire with a wire or paper clip. (At your own risk. Set pins first tape off and turn on by plugging into wall) . Good luck.

You should check if your PSU is providing enough power to the hard drive. In case the hard drive requires more power, you should either replace it or get a better PSU.

I just got this Vectra VL420 from a surplus store. I try to start up I get this funny music and then two beeps. I understand two beeps indicate power problems. But not sure what to do to rectify this....

From memory I would say you are in the right ball park.
I remember now. Error 2 means the power supply is in protect mode.
First check the wiring going to the Motherboard from the PSU. There is a four pin connector that lets the PSU know if all is well with the main board. If that is not connected, that may cause your problem
Try a new PSU. They are fairly cheap. Match the power on the specification panel stuck to the PSU.
If those don't fix it, a new motherboard is the next step.
Hope this helps.

Upgrade a dell dimension 4500-p3 motherboard to a duo or quad motherboard

You can do this with case modification as well as a new psu as Dell used proprietary mb's, psu's & cases on this model Dimension. To tell you the truth it would probably be cheaper and easier to pick up a core2duo or quad barebones kit than trying to modify the Deimension. Just my opinion. Remember Dell psu's are not wired the same as industry standard and their motherboartds in these older units are not top quality. Hope this helps you out.

New psu for Shuttle XPC SB81P won't work!

Try these:

Remove the PSU from the case.
Plug it to power.
Turn it on
Using a paper clip, short circuit the green wire pin with the the black wire pin on the 24 pins connector.
If the PSU fan start, remove the clip. The fan should keep spinning. That means that the PSU is working.

If the PSU is working, then the power up pins on the mother board might not be shortcircuited by the front panel switch.

Connect the PSU to the motherboard and to the power, turn it on. On the motherboard, locate the power up pins and short circuit them with the paper clip. If the computer powers up then there is a problem with the power on switch.

If the PSU does not start at all, return it.
If you can't return it, unplug from power, open it (warrenty voids!) and look for a fuse that looks like a one inch glass tube with metal caps. inside should be a wire. If the wire is broken, buy a new fuse in Radio Shack.

Hope that helps.
