Summary: I've bought Antec in the past and they've held up really well. This is a good deal on a basic 550 watt psu with a 120 mm fan. Modular, which is an added bonus. 80 plus certified is nice, saves you a little on your monthly electricity bill.
Pros: Got it on a good deal with a mail in rebate. 120mm fan keeps it cool. Antec quality
Pros: nice modular cable unit. I bought it to replace a low end power supply unit in a pc I purchased used for a friend. Can't fly out to fix it too often so I needed something with good reliablilty that was economical.
Cons: BUILT A SYSTEM ON IT. AFTER I HAD ALL THE WINDOW UPDATES DONE AND READY TO INSTALL SOME SOFTWARE THE COMPUTER SHUT OFF. PUT ON MY POWER SUPPLY TESTER AND IT FAILED ALL THE VOLTAGES. NOW IN THE PROCESS OF RMA. HOPEFULLY THIS IS AND ISOLATED INCIDENT.
