This is a Genuine Athena AP-MPS3ATX40 not a Substitute - 400 Watt Upgrade for HIPRO Power Supply Model HP-D3537F3R LF, H

Placed it in an old Dell 960 MT I was allowed to take home from work. Refurbished by me later. This PSU was an upgrade over the stock 255 watt Dell PSU. Wanted to upgrade the video card and the PSU just wasn't going to be up to the task. The small form factor size is almost identical to the Dell model. The only issue I had was trying to use the SATA power connectors into the two hard drives, which are located in the lower front of the case with the Dell caddy forcing the drives to be upside down (nice on Dell) and butt up against the side cover. The connectors must be right angled to have room to close the case properly and not lose connectivity, which happened with the lower positioned hard drive. Working on that issue now.

Great product that was very easy to install and adaptable for my older HP Pavilion. The power supply was substantially smaller than my old one so I have more room in the cabinet. It has additional wire leads if I choose to add components. Shipping was extremely fast.

Merchandise arrived on time and fit my computer perfectly. I only wished that it had brought an extra sata plug for my playback and that the cables between the sata plugs were longer. It was a tight fit, but my computer is up and running. Reliable seller and will do business again. Thank You

the item is working for more than 2 months very good I can't complaint so far hope it last a long time!!

got it and it solved my problem as it was a direct replacement

Fit well and works great. A little louder than the original, but not bad. Would buy again.

Works great - only one issue - This is smaller than the power supply it replaces (technical specs are fine, but no dimensions in the description) - so it's hanging on by one screw while I build an adapter plate.
