Hello, I recently bought a CX500 PSU, and i have an issue with it. When I unplug the wall power cord and then plug it back, the PC turns on by itself and all my BIOS settings are reset with a MemOK!...


Did you check the battery on the motherboard? The battery should read 3.3 volts with a volt meter. If you don't have a meter you can try swapping the battery from another motherboard. Or have the battery checked at a Radio Shack store. Also if you still have the Seasonic try hooking it back uo temporally outside the case to check if it is a power supply issue. If the old power supply failed while being connected to this motherboard it could have damaged it.

You won't get any 'fireworks' or 'smoke', widsss.

A) Make sure the Power On switch is connected to the correct pins, in the Front Panel header on the motherboard.

(The Front Panel is the plastic front of your computer where the Power On button, HarDDrive activity LED, Power On LED, etc., is located.
The pin area on the motherboard that the Front Panel cables (Wires) plug into, is the Front Panel header)

Either you do not have
1) The correct cables (Wires) plugged into the motherboard from the Front Panel,
or,
2) A bad Power On switch,
or
3) A bad Power Supply
Even if the Power Supply is brand new, it can still be a dud.

There is a simple test to see if the problem may be the Power On switch, or the Power Supply.
After you have made sure the problem is not incorrectly attaching the wrong wires, from the Front Panel to the motherboard, reply back in a Comment, and I'll detail out the simple test for you if you wish.

ALSO:
B) Make sure the 4-pin ATX +12 volt power cable is plugged in, if your motherboard uses it.
It's power for the Processor.

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

C) Your motherboard may not use a 4-pin +12 volt power cable. It may require more power.
In this case an 8-pin EPS +12 volt power cable is used. The equivalent of two 4-pin +12 volt power cables.

http://www.playtool.com/pages/psuconnectors/connectors.html#eps8

(Note*
1) Red wires are 5 volt
2) Yellow wires are 12 volt
3) ANY Black wire you see is a Ground wire )

I await your findings.

There is no power switch on the enhance atx 1123b that I have . What actually powers it up?


Just about every power supply I've owned doesn't have a power switch. The power supply is turned on by one of the wires in the 24 pin connector. According to this it looks to be pin 16 and how to turn it on:

"Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF."

Hope this helps

I'm not sure what you mean when you say the case wires don't match the diagram. You might mean there is already a plug on the end of the wiring, and this plug doesn't match the board header. If you're reusing the case from a name-brand machine like a Dell or HP, this is possible. They often get custom versions of motherboards made, and their front panel connectors are usually a nonstandard layout. On the other hand, in a generic retail case, the front panel wires normally have separate connectors on the ends for the switches, indicator LEDs and any front panel USB and audio jacks.

This is the front panel header diagram I found in the manual for your board (I looked at version 2, but the connections should be the same if yours is a different version):

pgh_pa_guy_3.png

This board has an Intel standard layout for the header. If your wiring has separate connectors, the start (power) switch wires will plug onto pins 3 and 4. I have never seen a retail case come with anything other than a two-pin plug on the end of the power switch.

If you are dealing with a custom plug on your case's wiring, what you can do is remove the pins from the housing. They almost always are held in by a plastic tab on the connector shell that engages a tang on the pin. Use a thin object like a small flat-blade screwdriver or a knife tip to lift the tab and you can slide the pin out. Insulate each pin with small-diameter heat-shrink tubing if you have it, or a layer of electrical tape. (I prefer the heat-shrink tubing, which is neater and more permanent.) Then you can put each pin over the corresponding pin on the motherboard's front panel header. Unless the pins are very loose, they will stay in place by friction. I often use this technique when salvaging a case.

As for the CPU fan, be sure you have the connector over the right pins. Here is the diagram from the manual:

You might need to rearrange the pins in your fan power connector if they don't line up correctly. This layout looks a little strange.

How to power up a compaq 243890-001 power supply without the the motherboard? Its not green to ground


Remove Power Supply
1 . Shut down your computer and unplug the power cord and all cables connected to the system.

2 . Open the computer case and disconnect all power connectors from the motherboard, drives, cards and fans.

3 . Remove the four screws that secure the power supply to the case. These screws are located on the back of the computer case, at each corner of the power supply.

Wire and Start Power Supply
1 . Switch the power supply to the "Off" (sometimes "O") setting.

2 . Insert the end of one wire from a single pole, single throw (SPST) switch into the green wire of the ATX power connector (the largest power supply connector).

3 . Insert the end of the other wire from the SPST switch into the black wire of the ATX power connector. If your power supply has two black wires, connect the SPST to the black wire directly beside the green wire.

4 . Wrap electrical tape around the ATX power connector and wires from the SPST switch to hold them in place. Make sure there is no exposed copper or silver wire from the SPST switch wires.

5 . Turn the SPST switch to the "Off" position, if not already set. Plug the power supply into the wall outlet and switch it to the "On" (sometimes "I")setting.

6 . Connect any other computer components that you wish to operate without the motherboard, such as fans, drives or cards. Turn the SPST to the "On" setting to activate the power supply.


Hope the above information will be helpful to you.
Thanks.

Yes, and the power supply needs replacing.
4 screws hold the power supply to the cabinet or case these are usually located outside visible at the fan vents at the four corners.

I would like to know how to troubleshoot a brand new Ultra LS600 power supply. I would like to go beyond hearing "it's dead" since I am getting power to the motherboard (via indicator light)m but the PSU...


You can start the PSU manually with a paper clip.
Remove the 20 pin connector from the motherboard, leave the four pin power connectors attached to your various drives (this will provide a load on the power supply when it start up (provided it is not faulty).
Look at the 20 pin connector with the connector facing you.and the locking clip to your left.
The fourth pin from the bottom LH corner should be a green colour wire and the next two wires (5th & 6th pin) should be black and next to the locking clip.
Straighten a paper clip and insert it into the 4th pin and into the 5th or 6th pin (ie connect these wires together). These wires connect to the front panel switch to turn on your computer. You are testing the power supply only and since it is not connected to the motherboard the computer won't start.
Now connect the power unit to the mains and switch on the mains, if the power supply is OK the PSU fan should spin up and your hard disk should also spin up. If nothing happens the the PSU is faulty.
You can test the +5volts and +12volts supply on a 4 pin power connector with a multimeter. The red wire is +5volts and the yellow wire is +12volts and the black wires are negative (ground). The voltage readings should be within 5% of these voltages.
There are other voltages to be checked +3volts, -5volts, & -12volts. but these are not as critical.

Try unplugging, then plugging back in the 20/24pin power connector. When you plug in the power connector, make sure the power supply is OFF and the switch in the back is OFF and nothing is plugged into the computer.
