Failure on powerup?

I just tried to move my GQ machine (Fedora 5) with 741GX-M to a UPS (APC 350 ES). When I tried to power it up, it failed. The CPU and power supply fans spin for about 2-3 seconds then power stops. I see the power light come on to the CD-ROM and possibly the HD (front of bezel). There are no beeps. If I try this a few times in a row, after a couple of tries, the fans do not even try to spin up. I've tried removing the floppy and CD drives from the power chain, and tried removing the memory modules one at a time, but no changes. Is this a PSU failure or a motherboard failure? I don't have another ATX power supply to try.

Re: Failure on powerup?

I suspect that your PSU is faulty... can you buy another one? This is a fairly typical of a "Blown PSU" symptom to me... I would try replacing the PSU, and then connect ONLY the Motherboard, if OK, then Hard Drive, if OK then .. and so on.. I advise this as it MAY be something connected to the PSU that caused it to "Fault" but generally they just go Toes Up for no real reason.. other than PSU component failure.

Sir, My PC is starting problem, 1.Starting UPS - ON the system starts automatically without swith ON. 2.After Starting the keyboard & Mouse get stuck 3.after Restart the the keyboard & Mouse...

The UPS may not be sufficiently stable on power-on to run a PC immediately.

Try going into the BIOS setup after the restart and look for the option that has the computer "Start up automatically after power failure." Turn this off. That will take care of problem 1.

If this also takes care of problem 2, you may want to check whether the UPS has a problem. Start by plugging a couple of lamps with 100 Watt bulbs into the UPS outlets instead of the computer. Turn it on - the lamps should behave normally, not flicker or change brightness. With the lamps and UPS still on, unplug the UPS. The lamps should stay on with little or no change, and the battery warning light should not come on right away. If the UPS fails this test, its battery may need to be replaced or it has a regulator problem.

My BR550CI-IN - APC does not give power for even 3mins when power cut

This problem is due to the backup of the battery. Your APC battery has exhausted completely & you need to replace the battery in the UPS.

What power supply do I need for the Gigabyte GA-MA790GPT-UD3H Motherboard. I will be using an UPS to keep power on for 10 minutes if the mains fails.

At an average PC with 17"CRT Monitor consumes 200-350 Watt. Allied peripherals and accessories etc. add to the overall power consumption. Hence, it is alway better to keep a buffer while estimating power consumption. So, It is recommended that UPS of atleast 500W may be used. (UPS of higher Power Output /Wattage would allow to keep up some other devices as well in case of power failure)

Also, CPU Power Supply (Internal) generally should be 350-450 watts.

Let me know if any further clarification/ assistance is required.
Hope it helps! Good Luck!

disconnect all external devices and then bypass the UPS and plug the power cables, monitor and computer, into wall socket outlets. Make sure and disconnect any ethernet cable as well.

Loss of power


if you replaced the psu itself and you still get no power, have you tried changing the power cable itself?
