Genuine / Original Bestec ATX-250-12Z REV. D7R Power Supply HP P/N: 5188-2622, PS-5251-08

Price was reasonable, unit arrived on time so that I could replace the PowerSupply on a DOA Dell. It served its purpose without fuss.

This was the exact fit for my hp pavilion i even changed the part myself without my husband help, it was quick and simple i am very pleased with my purchase packaging and shipping was very fast i received it in less than a week i will definitely order from this seller again thanks!!

I had it for 3 months and it stopped working alreadyNeed a new one to back up my data and walk away from this

The i.t. guy at work picked the item, i ordered it. It works, but the blower goes on and off sporatically, which i understand is a new improvement in power supplies. However, it is very noisy and cycles on and off even when the computor is "ideling". It does not give me a confident feeling in this product. It is, however, working and I am not going to replace it unless it fails.If this is the way that the product is supposed to work, then so be it, but it does not instill confidance.Amazons performance in delivering the product was quite satisfactory.

Fairly average PSU, but some HP machines won't hook up properly without it. It's a cheapie -- won't set any records for performance or durability, but it works.

works well, fast delivery!

I installed this power supply after the one in my computer failed. The installation took me less than 10 minutes. It was literally unplug all of the cables from the old unit and attach the ones for the new one. The power supply has been working very well and it was considerably cheaper than buying a new PC.

Power Supply barely made it a year. Intermittent shut-down of computer led to eventual failure of complete boot process. What I initially believed was a software/hard drive problem was actually due to this power supply.
