Summary: opened an RMA after it happened, never heard back from Antec about it -- looked into it more recently and they've replaced their old RMA system, so I guess mine got lost in the shuffle. luckily I'm still within the 3yr window, so I opened a new RMA and I'm hoping they replace my unit with a different model. after reading the reviews here, I'm afraid of using this model. I prefer not dying in my sleep.
Pros: does what it says -- 650w of power, very quiet, low power consumption, no issues powering my PC.
Cons: caught on fire after a year, took my motherboard and RAM with it. luckily the CPU survived.
Summary: Glad to see they are still selling PSU for so many years. It just works and works and works...
Pros: I made a review over 3 years ago, but I felt I needed to do an update. This Antec unit has run wonderfully this past 3 years, and I just recently in the past 2 months added a r9 280x and a FX 8350, which are of no issue for this power supply.
Summary: After 2 solid years of use it's 12 volt is running at 14 volts. This of coarse is causing all kinds of issues. I will have to rewire the whole setup with a new power supply. I wasn't expecting this to last 6 years or anything but I was hoping for more then 2. This is under 24/7 365 use though so keep that in mind when reading this. Under normal use it would have lasted a lot longer most likely.
Pros: Good low end power supply. Steady voltages and gives you what you need out of a 650 watt power supply. Quiet and no fancy lights (I don't want those for this application).
Cons: Not modular, but there are not to many cable to manage anyway. Gets a bit hot so keeping it in a cool area is a must.
Pros: Been running this power supply on my home file server for ~2 years now. Not one problem yet. Quiet enough to sit under my desk unnoticed. Powerful enough to drive a low-end RAID card and 5x2T disks.
