Works just like the original power supply did.
The power supply went bad in my Dell tower PC and I needed a replacement power supply. This one was good value for money and worked perfectly to get my PC back up an running. Works great again now!

Harness too short
One of the plugs is too short to reach a device on my Dell Vostro 230.

Disappointing
Failed within 4 hours of installing. Everything fit like it should, no problem with connectors or anything to indicate it wasn't made for my computer.

Works for my Dell Inspirion 530
My old power supply died and I needed to replace it because my 10 year old Dell Windows 7 machine containing 32 bit engineering software that is irreplaceable. I purchased this power supply and I am very satisfied. However, as other people have commented, I had to make some modifications which wasn't too difficult. I had to clip the pigtail for the hard drive power cords off of my old power supply and solder/heat shrink it to the new one to reach my dual hard drive set up. The power supply did fit the original space perfectly and snapped in place. But the other issue was that I had to drill a hole in the back of my computer case to secure the power supply since this is a typically generic replacement unit and the screw holes on the new p/s were located differently. Other reviewers commented about the fan being loud. It is a slightly louder but not distracting. Overall, as I said, I'm very satisfied. My Dell is up and running!

Extremely noisy PSU from an Electromagnetic Interference (EMI) perspective
I work with LF and VLF radio receivers and although that part of the spectrum is already crowded with spurious products from other cheap consumer electronics in a suburban environment, this PSU contributes very high-level spurious products from 200 kHz on up. The spurious signatures only change in frequency between PC ON, Standby, and OFF. The only way to get rid of them is to unplug the PC. My original Dell PSU was very EMI quiet, as most other high-quality switching supplies. My guess is that the primary and secondaries of this unit do not have adequate EMI filtering.
