My Dell died a few years ago & I bought a PowerSpec from Micro Center. I have been really satisfied with it until last night. It wouldn't power up at all...nothing came on. I done the usual routine checking the outlet, the plug, the surge protector etc. & still nothing. I sit up last night until 3:00 am surfing the Web on my wife's laptop. I found some info about changing out the PSU (power supply unit) :). I called Micro Center & found out they charge $39.99 to check it out & any repairs start at $99.99. This really encouraged me more. I opened up the cabinet, looked around & thought not much in here at all. I took the PSU out of the Dell & switched the units. Not a big deal I just concentrated on one plug at a time. I turned on the power expecting it to blow up but WOW I did it..up & running great. This reminds me I need to do some backing up on my stuff.

Jim, you are a braver man than I if you had the guts to go into a computer.

 

That sounds like electronic brain surgery to me.

good job on replacing the power supply

 

you were lucky that the power supply would exchange

 

inside the power supply is a little fuse that burns out

that is what happens to most power supply

Both PSU were the same wattage & had the same number of pins for the mother board is why I tried it. I was going to buy one because their not that expensive. The fuse was a thought also & since now you tell me  there is one inside the box guess I'll see what the inside of it looks like next. Thanks!

The biggest thing to worry about with power supplies were the older ones with just the molex style connectors. Using them on a newer computer could be done but you would need an adapter to go from the molex to sata connectors for newer hard drives and accessories.

As long as the Dell PSU keeps working I'm leaving it alone. I was just going to educate myself a little on the bad one. I also discharged the capacitors but will use caution anyway. I remember years ago my Dad opened up the back of our TV to take a look. He immediately found out what a booster was lol.

Jim, good for you!  Swapping out a power supply is not hard, as you found out,  and saved you some $$$.  Most of the time when a computer will not start it is the power supply.  One thing I would caution you on is to make sure your are grounded as you work on one. :thumbs: :thumbs: :thumbs:

Capacitors are so small that they won't hurt u in a computer power supply as long as it's unplugged.  The main cause of failure that I have found is that they seem to be a dust magnet and tend to get overheated.

Could you show us how this is done? Jumper cables to the bathroom faucet?

Well since that is your office jumpers should work out just fine!  Just hook one to the faucet and the other  to your tongue, you should be well grounded then.

 

But for us more normal folks simply by touching the chassis while the computer is still plugged in will get rid of any static electricity you may have.  They also make a bracelet you can where that connects to the Chassis that keep you grounded.
