420W 420 Watt ATX Power Supply Replacement for HP Bestec ATS-100, ATS-150, ATX-1953D, ATX-1956D, ATX-1956-B1, ATX-1956F,

It worked perfectly, it is more power than what it replaced, that's great, it is smaller in depth, less cramped than before, it has an additional flange for mounting, which I didn't need, but I thought that would be useful in some other installations, the flange was optionally removable (2 screws). Has an abundance of connections with generous cable lengths. I gave it a 4 on noise level because it could be quieter, but in my case, once it was under the desk, I couldn't hear it. being a higher power rated PS, maybe it was designed to pull more air, making it not "silent" .All in all, a good choice, product and vendor, I would buy it again and would not hesitate to purchase from same vendor

Purchased this to replaced a failed unit in a 20yo HP Pavilion. So far no issues and it's running quieter than the original. Had lots of extra connectors that I didn't need, including an oddly placed 4 pin molex connector coming out of the 20pin power plug.

Arrived in a timely manner. Fits in the case as expected.

Great product and great seller. I ordered online on Tuesday, and with "standard" shipping, I had the product on Friday. This is a power supply for my computer. It was the correct one, and at an unbeatable price. I installed the power supply, and it works just fine. I would definitely recommend this product and this seller.

works great. brought my pc back to life with more power than it had before. taught my 15 year old son how to install it. Great purchase, thanks! Oh, on of the cords was a bit short, but we moved the hard drive up to the slot below the cd rom and that soved the problem.

The last PS I had fried - this one was perfect! Started right up, computer humming along!

Just as expected. Fixed my computer myself. Saved about $150 by not taking it to a repair shop!

Probably not the most energy efficient PSU out there, but for 30$ it's a good replacement for a failed PSU on my server.This will be on 24/7, let's see how long it takes before it fails, for now I will leave a positive review, also the fan it's a little bit loud, but again for the price I can't complain.

Hpower supply arrived on time and was easy to install in thr same location as the original, wiring harness was in a slightly different exit position on the power supply box, but that was not a problem as there wa ample wiring harness length. Computer powered up immediately and is running just fine. My compliments to the manufacturer and the supplier for e.xcellent servvice.
