Upgrading Power-On Button Wires

Is there any such thing as changing out the wires for the Power-on button and LEDS, Reset Switch and LED to bring the desktop case up to P4 standards or will I have to invest in a new tower case? It just seems to me that if I'm able to switch out the power supply, I should be able to switch other related items to bring the case or items up to the needed standards.
Many thanks for any ideas and answers whether good or bad?!

Ok, so we have an old case, right? Now, if the back plate is a correct P4 standard plate - IE there is all the right holes in the right places, then you should be right in changing the power supply. What you will need:

1 new power supply and
1switch (simple push button) for when you change th epower supply, the original button is removed. It is completely incompatable with the new one (unless it is one where it doesnt click)

If it is one of the above, just change the PSU. otherwise,you will need to mount the new button onto the case. The LEDS etc will be fine.

I was not aware of any differences beyond the power supply for P4 boards to the ATX standard.

Is this an AT or ATX style case?

If it is an ATX case, you should only need new connectors on the wires to match your new motherboard.

A few good sources for connectors and terminals are: Digi-Key www.digikey.com
Hosfelt Electronics www.hosfelt.com
Cyber Guys www.cyberguys.com

If the case is an AT style, you will need an AT to ATX conversion switch.
I believe that Cyber Guys carries one of these.
Remove the AC wires from the old switch, and wire the new switch to the motherboard.

If you could provide specifics of the case and motherboard it would help.

If you wish, you can e-mail images to me at thechas2000@yahoo.com and I will see what I can figure out.

PCTECH,

Read my first line carefully.

I said BEYOND the power supply.

I am not aware of any other differences to the ATX standard for P4 motherboards.

Yes, some have different I/O shield configurations, but they should still follow the ATX standard for power and LED connections.

Now, if the case is an AT style tower with the ability to accept an ATX motherboard, I can understand the wiring differences.

This is directed to TheChas. The difference between the standard ATX power supply and the P4 power supply is the "P4" 12 volt connectors that are not on the standard ATX power supply. The P4 power supply will also have the a six pin 3 volt connectorthat was not included on the standard ATX power supply. Ypou can see a diagram of the P4 power supply by following this link.

Hope this helps

To be honest, if you haven't bought a new power supply yet it would really be in your best interest to just get a new box w/ PS. If you want to rewire the switches and LED's for the sake of doing so, that's cool but you can pick up a good case w/ PSdirt cheap. You will probably even find one with a more convenient layout than your current case i.e. more space, rail-mount drive bays, etc. Just food for thought
