Summary: What a smoke machine this is! As a power supply it is terrible, like others here I installed this power supply after checking all connection and it fired up once then stalled and started smoking and ruined the HDD and I received some nasty burns to my thumb and index finger for my trouble. This junk is going back and I would seriously advise anyone considering this power supply to look elsewhere and spend more on a better quality unit. Very disappointing.
Summary: Burned out within 5 minutes of installation. It feels like there's nothing in the unit (my old 250 W unit that is being replaced weighs at least 3 times more) - light, cheaply made - well, should have known better. I thought it was similar to there other 480W unit but the other one has dual cooling fans and is only a few bucks more. The other one works fine (but don't know for how long) so decided to save a few bucks and get this one - BIG MISTAKE.
Summary: I had my doubts considering this is the 2nd power supply I ordered from logisys. The first one was white. Brand new. It smelt brand new but it also had a smell of burning rubber or something. When I connected it to the wall unlike this one it had no sign of working and I was afraid to even put it on my new motherboard. I had it tested. DOA. Burnt out and bad. However by accident I ordered this one and didn't pay attention to the company name.
Summary: I used this is a SFF frame which required some mod work on the case, but I made the right choice. It runs quiet and gives me the power I need for the use I need. In fact my cousin's PSU went bad six months after she bought her new Dell and I bought another one of these to put in her PC. She has not had power problems since and she affirmed to me it runs quieter than when her old PSU.
Summary: I bought this a few months ago to replace a loud/aged power supply in a PC that's a couple years old. It was easy to install as long as you aren't afraid of wires, and is pretty quiet. The only odd thing I've come across is turning on the PC when it was very cold outside (and maybe 65 degrees indoors). For about 2 minutes, the supply fan would make a very loud noise. Once it warmed up, it was just fine.
Summary: This PSU died after a very light use, in computer used mostly for checking an email and web browsing, in less than 8 months (bought it on October 8 2013 - died a week ago). "How much money, that much music.
Summary: This was a excellent cheap power supply. I works great. I have had no problems with the power supply as of yet. This is for a low end computer so I wasn't looking for a high end one with a lot of extras.
Summary: i bought this power supply to modify it for a power bench top project. after tinkering with it for a bit, i realized something odd. the actual pcb was cracked off at the corners , and the fan was non functional and seemed like even if it did work it would spin on more axis then it should. because its already modified i cant return it, so i figured i would just leave this angry message here.
