Question about Bestec (ATX100-5) (ATX1005B) Power Supply

PC won't turn on.

Hi, I have a HP xg922 model PC with a Bestec Power supply (model: AXT 100-5), and it won't turn on. The monitor is in working order, the voltage switch is set correctly and the hard drive and switches all seem to be okay, so why won't it work?

Bestec power supplys go bad and supply the motherboard with the incorrect voltage eventually killing the mobo too. I fix about 2 a week.

Take the power supply to a retailer or computer shop in your local area to be tested. Pretty standard from what I have found out.

If you didn't accidentally unplug the four pin connector near the CPU, you need to replace the power supply. This is actually a fairly common occurrence with the cheap ATX power supplies being tossed into systems these days.

I have a bestec atx30012z and the power turns off after a few seconds of turning it on.


Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacement from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic

My power supply is blinking green light and my PC has no power


plug your pc directly to your wall outlet and see if it turns on. If it works, then the problem is your power supply. If power supply has a reset button, press it and try again. If pc does not turn on when plugged to wall outlet, then power supply for pc may be out.

Blinking power supply LED


Your power supply is fried. I had the same problem with my Bestec ATX 250 power supply. I fixed the problem by installing the StatTech model: ATXPOWER250. It was easy to install and works well. It is almost identical to the original but more quiet. I got it for $29 at MicroCenter.com. Also at online Newegg.com, Radioshack.com, Provantage.com, June 20,2009

Bestec atx-250-12z rev d hp model 5187-1098 pc will not start up when pushing button on front of machine green led on back of p/s flashes with power cord plugged in. does this indicate a p/s failure?


I have already replaced mant Bestec ATX-250-12E power supplies because they have an internal failure. Consider yourself lucky if the thing doesn't power up your computer because it has a problem of imposing the +12 volt line onto the +5 Volt line then blowing out the mother board. Sometimes you aren't so lucky because once the damage is done then it is to late to just simply replace that piece of junk. I was lucky with my daughters E-Machine because if she tried pressing the start switch on the front of her computer it would sometimes come on and sometimes not. She just mentioned this to me and I immediately replaced that Bostec ATX-250-12E before it could do any damage to her computer. If anyone has an older E-Machine or an older Gateway machine then it would be a good idea to see if it uses that Bostec-ATX-250- 12E. If it does then go order another power supply, anything but a Bostec, and instead of a 250 watt order a 300 watt or better. I hope that this has helped those that might have this problem before it destroyes *********** boards. Marty

Upgrade for Bestec ATX-1956D (HP p/n: 0950-4106)


How about the LC Power LC350M Micro ATX - 380 Watt

or the 

Logisys 350W Micro ATX

They should fit your form factor and output as much as 350W being relatively cheap, but neither gets 18 amps on 12V rail...
I think no power supply of that size has an output like that...think about a cheap but substancial chassis upgrade if you need that power...Have a look at directron for the PSUs.
