Bestec ATX-250-12Z D2 HP 5187-1098 Genuine 250W 20-Pin ATX Power Supply - NEW

I work for a business that exclusively uses Mac, but our billing is done on an ancient HP Desktop. One day it went poof, and we were really screwed. I Googled the problem, which turned out to be the power supply. After popping off the shell of that old dinosaur, I snapped a pic of the model # of the defunct power supply and took to the internets. I was fortunate to find that many sellers carried it, and ordered from the seller with the best deal. Three days later, the old beast was back up and running, faster and better than ever. The power supply came as described, and required no additional parts/wires.Additional Notes:- 1 -Be smart when you replace the thing. Be sure you're ordering the correct part. Be sure the computer is off (duh) and everything is unplugged, and be sure you take pictures or video (or have instructions) when disconnecting the wires/plugs from the old supply. I thought I didn't need to, and it cost me 10-20 minutes digging online for something to reference. The whole thing should take you 30 minutes or less.- 2 -Amazon could be a little more specific on which shipping option to select for items with the "Order in the next 'x' minutes and get it by..." text attached to the listing. Amazon said I could have the item by the next day- but didn't mention how. I chose expedited shipping (1-3 days) and got it in 3. No big deal, but it bugged me a bit. If you tell me I can get it by tomorrow, at least tell me which shipping option will make it happen. The seller was not at all at fault, and the customer service rep was very helpful when I contacted them about it.

Purchased this item to replace the power supply that went out on my HP desktop computer. Light in the back of the tower started blinking and computer went out. Tried the old "hair dryer" trick into the old power supply but it only lasted one day before it started blinking again. Recieved the wrong unit (my fault) for the computer (short cable) but fortunately the seller was about a mile from my house. Drove over and they had the correct unit available, so we swapped them out. I installed the new unit myself and made the wiring was done one at a time, from the old unit hooked up to the new which made it very easy. Works fine now.

This is the second one I've purchased. The first one lasted just a couple of years, but the computer I put it in is way over the hill and I don't want to spend a lot of money on it. I really should have replaced the computer by now, but I put it off and I needed to get it up and running to get the files off the hard drive. The power supply came as ordered. It was a breeze to install and works perfectly.

This Bestec 20-pin power supply was as close to identical to my original HP 250 Watt power supply as I could find. That meant when I was removing my old power supply that all the plug pins were an identical match and so replacing the old unit turned out to be a relatively easy, unplug and replug each of the pins. This unit has a green light like my original and works great. I am very happy with this power supply and would recommend it to anyone that wants to keep their old computer when its power supply wears out.

used power supply. Part is exactly as described and works well. Power supply is very quiet. Generic replacement power supplies may not have the variable speed fan. Bought a used one because the generic replacement fan ran at full speed which was noisy and the cooling vents on the replacement were not on the bottom like this one.

I bought this power supply to fix my computer that broke an I did not want to expend in a new one... So I decide to buy this product useCheap and works just perfect. Easy to install

It was delivered pretty quick, I took out the bad power supply and replaced it with this one and the system booted right up. Overall I'm very happy with this product as I was able to extend the life of my mother-in-law's PC and not have go through the hassle of teaching her a new operating system.

This unit performed well until two months ago. It lasted only one year. Now the green light is flashing and I have to use a hot hair dryer to reset it every couple of hours.One would think a replacement part would last at least two to three years if not longer. Too bad I can't return it.
