Good 400 Watt supply with all the connectors one could need, including an innovative ATX 20+4 setup with a 20 pin main plug and the +4 separate plug so whether you have an older motherboard with a 20 pin connector or a newer one using the 24 pin connector, this supply will work. Also has a good mix of older 4 pin molex style peripheral connectors and newer SATA plugs.
What's great about it: Inexpensive reliable power supply
What's not so great: N/A
I would recommend this to a friend!

If you are trying to upgrade your computer and add extra stuff you need to make sure that you have enough power to run the extras. The power supply is set for what you got when you bought it most of what you add on needs more power. In may case I add a Graphics card that will make the quality of my videos mutch more addvanced. any way I would like to say I do like it. It brought back what what most whould pronouse dead. By the way I put it on an old Compaq window XP
What's great about it: I can up grade with it.
What's not so great: Directions could be better

Like a lot of other posters, I wanted to get my comp up and running in a hurry. Talked to a service guy that said if the PSU didn't work, I could bring it back for a refund. Because I wasn't sure if that was the problem, I thought I had better go for it.
It works and was easy to install. Way over priced for an off brand unit but convenience often takes precedent over price.
For a 10 page, in depth, report on this unit check this out: http://www.hardwaresecrets.com/article/557
Their big complaint was price. It is not a high quality PSU in their opinion and that is a concern for me.
If it gives me 3 more years on this 7 year old comp, I won't complain.
I recommend only on the basis of convenience. It's too early to tell if it was worth the money. You will hear from me if isn't.
What's great about it: It works
What's not so great: Price

This was a second replacement for my Dell. The size of this PS was a bit bigger, but I got it to fit. I thought it was a great value when I first bought it, but it's only been six months and I've already smelled it burning, so now the fan barely moves. I'm replacing this with a Cooler Master PS.
What's great about it: Price
What's not so great: Longevity
No, I would not recommend this to a friend.

My HP Pavilion desktop had been giving me trouble for several months. Since I bought it in 2008 and already upgraded it once, I was debating whether to replace it or take it in to have it evaluated and fixed if possible. I had a hunch that the problem was the power supply since it had been replaced before. Not wanting to sink too much money into it, I decided to try replacing it myself. I know enough to be dangerous around such things, so I did my homework first by watching YouTube videos on replacing power supplies and looking at options online. This unit was pretty inexpensive, and I happened to catch an in-store sale which made it even better.
You have to make sure that the Amps are sufficient and that the box itself can fit inside your desktop. (It’s not an instance in which you can “overbuy” to increase your power since the power supply may be too large for your chassis.)
The problem is that the power supply is generic and every PC is unique with different configurations. The components within your desktop that require power connections aren’t color coded like the back of your CPU (green and purple for keyboard, mouse, speakers, etc.). So you need to be very careful when you open the chassis to note the current connections (make a list, take pictures, shoot a video) so that you can make the same connections when installing the new one.
I also had to remove a few other components to access a few connections, including the primary fan, hard drive, and CD/DVD drive. This was stressful because of course some jiggling and extra effort were required. Ultimately it was possible but more stressful because it was more to remember and more to reassemble.
I made all of the necessary connections but still couldn’t get the PC to boot up. I retraced my steps and couldn’t figure out the problem, so I ended up taking it to an expert to be looked at. That person required a few attempts to discover that one of the connections (the 20+4 to the motherboard) wasn’t in all the way. He had to apply a bit more force than I had and wound up charging me $30. While I wanted to avoid having the PC professionally serviced, at least this got me running again and much cheaper than replacing it. My goal was to get another year out of it – fingers crossed!
