DIY with patience and perseverance Posted by: from: Philadelphia, PA on 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!

Works perfectly for a value power supply Posted by: from: on I was forced to buy this because my power supply crapped out and I needed a quick (and temporary) replacement. My intention was to buy the cheapest power supply I could find to tide me over until I bought a replacement quality power supply. Well, this one has been working fine for a few months now with no issues I don't think I will spend any more money on a fancier one. Also, fan is silent. I measured the sounds coming from the various fans and my chassis fans are a lot noisier than the power supply's fan.
