Summary: Power supplies are always iffy but nothing has gone wrong with it and it seems to put out advertised power. The only reason i did not give it five stars is because I have only had it for a couple months.
Summary: Unit works really well for 3D printers. Have a GEEETECH Me Creator that came with a really lousy power supply that blew almost as soon as it came out of the box. Bought this as a replacement, modified it so it would run with my 3D printer, and have been printing well with it ever since.
All cabling and connections fit nicely. Taking away one star due to the following

Summary: Replaced 300 watt power supply on older dell inspiron quad core 8300 based machine. Took about ten minutes. All cabling and connections fit nicely. Taking away one star due to the following: Watt rating is peak not RMS. Fan is noisier than anticipated from manufacturers' claims.
