Question about Gateway (6500683) 160-Watt Power Supply

1 Answer

Gateway Profile 4 PS Have 20 bad units that need fixing!

Thought it was just a blown fuse, but no. Some have ramping problems that go from almost zero to 12 volts on a digital meter, and then drop back down repeatedly (power LED goes dim and then bright). Some have no DC output, and I had also replaced a few N channel MOSFETs that were burned out (soot evident) and attached to a thick heat sink. After replacing some of the smaller TO220 sized chips, still no DC. These are all mostly Delta ADP180 power modules like the photo. Some have a power LED and some don't. Even invested in some hard to find MOSFETS (from ST Microdevices) for these, in hopes that just replacing the chips would fix some of the problems. I do hear a 'click' (like a spark sound) when I plug in an AC cord so I know power is going in, but it never gets to the DC out end.

In today's times most people don't service power supplies because they can catch on fire at anytime and with the litigious society we live in today, it isn't worth it to do it.

The best way to fix the problem is to get a new one.

E Machine ATX 250 -12E replacement PS


With emachine MOBO's you have to make sure you plug in the 20 pin plug from the power supply to the mobo. Also make sure all hard drives, cd/dvd roms, floppy drives, etc are turned on. Make sure the red switch on the PS is set to 115. Make sure the PS is plugged into a known working outlet. Make sure MOBO is properly in place with all grounds/screws in place and nothing metal near or touching board which may short it out.

You can review the E Machines PS replacement guide here for further instruction.

Good Luck,

Jesse

How to use ATX-250-12z SMPS with 24 pin


Chances are that 250w power supply is not going to power a motherboard with a 24 pin connector, but you can try.
You will need to purchase a 20 to 24 pin adapter cable.
