power supply question about connectors

by Algo / December 6, 2003 12:22 AM PST

I'm looking to replace my hipro hp-1603a3 power supply but I can't find anything close. Do I need the p7 and p8 connectors? Is the p6 for a floppy? This is hp part number 5185-2917. All the micro ATX power supplies that I look for have only a few connectors.

Why not just get the HP replacement?

Did you try ?

And many power supplies will have connections you won't use. This bothers some. Others will know that you can't make power supplies cheaply unless you consolidate the models.

It sounds as if you have a micro ATX mob/system. [from reading your previous inputs]
by Ray Harinec / December 6, 2003 3:25 AM PST

If the HP will supply enough power [if I recall you seemed to need increased power].

The P7 and P8 numbers are not common to all supplies. The ATX V12 supplies DO have two extra connectors. One for the 12 Volts that new mobo's use to supply more current to the CPU regulators and an "Aux" connector for various possible optional devices [not used in many systems.

The main issue here is why you need more connectors. Usually it means that you are adding hardware. Adding the connectors doesn't help the power supply provide one iota more power.

Wonder if you are trying to make a MIcro ATX system a server system. LOL

As for the "few connectors" you can buy cables from many places that will connect into one and have two connectors to use. These connectors are standard and you can adapt anything to anything else or expand the total number of connectors to use. Look in

I'm not trying to make it a server system, just trying to add a few things. I have to have a micro ATX power supply. If I get a regular ATX then the cd-rw and cd-rom won't fit!

I thought the green p7 cable was connected somewhere, just not sure.

Also I did get a split connector to turn 1 of the larger cables into 2 for both the cd-rw and cd-rom. The guy at the shop told me it wouldn't over work the power supply.

I've looked for a HIPRO website to no avail. Also the HP website doesn't tell me if there's a good upgrade for this power supply. Actually the HP website doesn't say much for a pavilion 7936.

So you don't need a new power supply?
by R. Proffitt Forum moderator / December 6, 2003 5:01 AM PST

There are Y connectors to split your usual power to supply that new CDRW. Cost is under 5 bucks and if you dropped by, free since I must have 6 unused ones from prior machines. Replacing the supply seems to be the hard way to solve this.

HP Pavilion a365c continuos beep - P7 removed

When I turn on the HP Pavilion a365c I get 5 sec continous beep. One by one I removed components. When I removed a cable label P7 the beep stopped and the computer seemed like it when through the boot process. however the monitor still does not display anything.

does anyone know what cable P7 is for (power for some device)?

Also does anyone know what this problem could be.
I rather not take it to the geek squad at best buy. Yet.
