Dell Optiplex 980 Power Supply Cheap and hot selling in Parts-dell.cc
Any suggestions would be useful as I am about ready to scrap the unit if I cannot fix it. Start by unplugging from the wall all of the cables connected to your computer. I contacted PC Power & Cooling (the company is now named FirePower Technology) who used to make Dell upgrade power supplys years ago, but they do not have a supply for this model of Dell. It's a 4-channel stereo, so I don't know if the total power draw is Watts/channel times 4 or how that is figured.<img class='aligncenter' style='display: block;margin-left:auto;margin-right:auto;' src="http://img.auctiva.com/imgdata/1/1/0/3/6/0/4/webimg/764266260_tp.jpg" width="280" alt=""/>
A power supply simply regulates, corrects, and modifies your home's electrical current to allow it to be used by a PC. Once again, the power supply (PSU) does NOT have a capacity of power in it that can be drained over time. Then came symptom number four… Power was present to the monitor and other peripherals; however, no power to the computer. I used the chat feature and after I told the Dell tech initially my problem - that my battery was dead — that I was NOT going to replace it at this time and that I was happy to use AC for the time being and all I wanted was to have them help me stop the orange light from blinking — the tech told me I needed a new battery!!

To connect a network cable, first plug the cable into the network device and then plug it into the computer. This is usually a simple process, but if there is little room in your PC, it may be necessary to remove other components to get the power supply out. A second lead from my original PSU has one SATA power connector and one floppy drive power connector.
Replacing the Dell PSU with another Dell PSU form E-Bay was probably not the best option. It also describes the various form factors and voltage levels, and how to protect your power supply. Step 5. Disconnect all other power supply leads to the motherboard (fan monitors, ATX12V, EPS12V, AUX). Do not install or remove components or perform other types of service to the inside of a PC unless you disconnect the AC power cord or turn off the power supply.
Unfortunately, while there are generally accepted standards for labeling power supplies, there's no equivalent for the laptop or computer itself. Cables routed over the cards can prevent the computer cover from closing properly or cause damage to the equipment. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Have to go through releasing the static electricity by pressing the power button for atleast 10 to 15 seconds while all connectors unplugged and CMOS battery removed.
