1 out of 5 eggsJunk

Pros: It did work for several years.

Cons: Blew a cap on power up. Wrecked cpu fan itself, and the sata hard drive which will not spin up any more. The cpu fan being out caused the cpu to smoke. Amazingly the cpu still works after cooling down.

1 out of 5 eggs

Pros: There are none.

Cons: This power supply is a piece of junk. I have had 3, yes 3 of these power supplies fail in less than 2 years. All of them had the same problem.

Other Thoughts: I highly commend Newegg with their return policy. They have handled my claims very promptly. I have no doubt that this replacement power supply will fail just as the others did

4 out of 5 eggsBad Capacitors

Pros: After buying the Sonata II case, I realized that many had problems with the included SP-450 power supply, so I sent an email to support at Antec, and received the following reply.

Mr.. Young
Please understand we did get some bad capacitors from out supplier and they were installed in the Smart Power Series. And with a capacitor they take time to go bad so the power supplies tested good when tested at production. We apologize to our customers that purchased these power supplies as we were unaware of this situation. But please be assured that the problem has been taken care of with good capacitors. If at anytime your Smart Power supply gives you trouble there is a 3 yr warranty from the time of purchase that Antec will gladly stand behind. Please keep the invoice as it is needed for any warranty work.

John Bowen
Antec Customer Support Supervisor

Cons: None as yet!

Other Thoughts: Capacitors are by far the electronic component with the highest failure rate. Being that the power supply has a 3 year warranty, it might be worth sending it in for warranty work. I hope mine has the good capacitors!

1 out of 5 eggs

Pros: Fairly quiet when working.

Cons: I'm now awaiting my third one of these from Antec RMA as this is the psu that comes with the Sonata II. I've only had the case for 22 months.

Other Thoughts: I think their neopower and truepower lines are supposed to be better quality, but you might be better off with a different manufacturer.

2 out of 5 eggsJust like everyone else

Pros: It's very quiet

Cons: Only lasted 11 months before it died. I thought Antec was suppose to be better than this but apparently this is normal with this particular PS.

Other Thoughts: Hopefully I can get an RMA and another one of these................to use as a backup for the new 500W Thermaltake PS I just got.
