Bestec ATX-300-12Z Rev. DDR Replacement Power Supply for HP P/N 5188-2625

My computer wouldn't turn on, so ordered this to see if it was the issue. Easy to replace, took 5 minutes. Plugged the computer in and worked like a charm!

Fit perfectly and works as advertised.

If you just buy this for work and web browsing etc... Its good but if you want this to get id recommend you get from 500 and up so it wont shut down your computer.

It arrived fast and I had no problem installing it. My computer was up and running well again, but in 4 or 5 weeks, the same problem occured again. Honestly, I don;t know that it was the new part or if perhaps I had mis-diagnosed the problem to start with . I bought a new computer so problem solved.

Lasted less than 1 week. Don't waist your money.

I had a client that had run his Tower in the Field on a generator and because of the voltage regulation on the field generator breaking down; his computer stopped functioning.He had been going to "toss it" because of poor advice from the "almost-knowing"; however he spoke to me about it.I tested it out and determined that perhaps the motherboard - and for certain the Power Supply - were damaged beyond reasonable repair.I'm actually an electronics designer - not a computer repair guy - so I insisted that there were two crucial considerations:1- he really required the info... although we could have dumped the HD's through a SATA/USB conversion (which I have - also available from Amazon) and saved the data2- If we're going to save the tower; I'd only do it exactly correctly... or not at all.Therefore I entered the designation-info on the original factory PS in Amazon and "there it was".Purchased it and when it arrived; I had to be cautious to put the New Unit In, because it was absolutely identical to the Original.Ordered the exact original Motherboard (more commonly done) for the tower - and it operates flawlessly as if it were brand new.Total cost for PS and MB --- about $120....... replacement for the tower - about $599....... and ....... he has all his original data.Amazon being able to supply the actual original PS is the foundation of this success... as is the quality and accuracy of the replacement PS.All is well..........

This matched the original power unit perfectly and was a snap to install.

Saved me way more money than it cost and I didn't have to drive to a computer store and wait for days till it was ready. I installed it myself and it was easy and only took 10 minutes or so. I'm typing this review using that computer now...
