Faulty I should say, becaue you can repair it. Just replace the Buldgy capacitors. you'll need a soldering iron, soldering lead and a ****** to desolder the components terminals. Remember replace the caps with only the specific values indicated on them and also when replacing them see how you removed them is how you'll replace them and solder them back, if you not sure to do it yourself then provide the Capacitors and asked a friend who can do it for you. But if you think you can afford a new powersupply unit, thats fine.

The 250series has been replaced with 300 or higher models. They had to much trouble with those.
However when I repaired the 250's not had any problems. One has worked two aditional years running 24/7

Does your motherboard have a beeper? Does it emit any distinguished beeps?
First, to locate the problem, try to boot your system with only a bare minimum of components: motherboard, cpu, ram, videocard. Try your system with a known to be good power supply. Then, if possible, try it with other known to be good components. If possible, check power supply with a psu tester or multimeter (that takes some time). Every bit of description of system behaviour will be helpful.

I may be wrong, but, seeing that it is only a 250watt power supply, its was probably cheap. NEVER buy cheap power supplies for PC's. Weak PS's can cause damage to multiple components on a computer.

Power supply led blinks but will not power up


My gateway was powered up and I came back into the room and it was not. It would not turn on so I checked the power supply with the paper clip jump method (which is the only thing I know how to do) and the green light along with the fan turns on. While it is plugged into the pc, it blinks with no fan running. The power supply is an ATX 300-12EB3. The Gateway is 556GE. Thank you for any help I can get on this.

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.

Bestec ATX-250-12Z Rev.C Green LD starts to blink


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

The pc wont power up and the green led on the PSU is just flashing, is the bestec atx 250 12z broken?


Most likely yes.

I would also reccomend an upgrade to that PSU when replacing it.

Something in the 450-Watt neighborhood is usually a bit more robust.

This is a link to troubleshooting power supplies for HPs. You still have a few steps to do to confirm but it appears your power supply is bad. I think they have you unplug the hard drives and take any cards but video out then unplug the power, wait for a while and then try again but if the light is still flashing the power supply is bad.

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
