Question about Bestec (ATX-250-12E) 250-Watt Power Supply

HP Mod a500n PC, flashing green ps light

After a service power failure, the PC would not power up. The green light flashes. I tried all the suggested remedies such as disconnecting/connecting the ATX power to the mb, recyling the power to the chasis, and disconnecting components.
The ps is a Bestec ATX 250-12ZD. In the past, there has been power failures with no bad outcome to any other units. I have seven TV including four flat panels, one pc, one laptop, various other electronic devices. Thank you for your help. Leo

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

Try this,Unplug the power from the back of the power supply,now hold the power button until you see the light come on and fade back out(usually takes 20-30 seconds),now plug the power back in and push the power button again.(You can watch the light on power button or on power supply box).

If this didn't work,Post back and we'll go from there.

No power on tower. The green light is on the back, flashing slowly, but unable to boot computer. Have tried unplugging for hours and holding on button for at least 30 seconds. This happened before, and I...


Hello Liz, hi, the flashing green light means its on stand by mode. when this happens, the power supply cant power on, due to... well like loose wiring, loose connections, or something on the computer. so I suggest you have it checked by a tech person, this requires that the whole PC be disassembled and reassembled.

Pc didn't start,flashinh green light in the back..I disconnect all inside and the green light is solid now,.How I can check my motherboard?


Failure of motherboards is usually due to breaking capacitors. A few years ago a capacitor company stole the "recipe" for making capacitors from another company and tried to make their own, unfortunately they did not get the ingredients right and the capacitors started breaking after 2-3 years of use. They sold these capacitors at very cheap prices and a lot of computer companies and power supply makers bought them. This is easy to diagnose. Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything. The dead giveaway is the fact that you are not getting a monitor signal and if you listen to your computer as it starts up, a few of the devices may not start (hard drive, etc). Mobos are usually expensive to replace because the computer makers have them made especially for them and only order so many. They usually do not have a lot of extras laying around. There are a few companies that will repair broken capacitor issues. Hope this explains why they can fail. They can also fail if overheated (like when a case cooling fan fails), the cpu is overclocked and not cooled down (which raises temps), the power supply fails or by lightning and power surges. Also if you add a bunch of extra components without upgrading the power supply you can suffer underpowered situations.
If you can get another power supply unit then you can try that first. Usually when the condition you describe happens it is either the motherboard or Power Supply. If you replace it with another PSU then you have to have at least the same or greater output watts.
