Summary: I just received and installed this today. One bad thing is that the documentation is very lacking. No manual is included, and the online manual is pathetic. That said, I am moderately experienced with computers and didn't have too much trouble. I like that most of the wiring is not permanent but instead they have several sockets so you can plug in only as many cables as you need. A bit neater and less crowded that way.
Summary: So far it has been running very quietly, even when playing games. Using a gtx 750 ti which is low power however. Can't comment on the sound or performance under demanding conditions. Since it's only 350w, I would probably need to replace this if I wanted to upgrade. Perfectly fine for a simple or low-power build.
Summary: The first one I got was DOA... the very first DOA i've ever had from Newegg (and i've been with them since 2002). The replacement process was easy and it came fast and worked. It has been in a Dell Optiplex 755 for almost a year now and still works great. Don't really have much to say about it because I just stuck it the machine and gave it to the user. Didn't really see any problems or annoyances with it.
Pros: - Does its job.
Cons: - First one was DOA.... must of been a fluke. The replacement has been working fine for almost a year now.
Excerpt: Product was installed by Staples as a solution to an ongoing power/shutdown problem. It worked well for a few weeks and then the shutoff problem occurred twice. I am still keeping the product because the problem occurence is less frequest than before.
