Inaudible - I cannot hear this thing above my Freezer 7 Rev 2 even with the CPU cooler at it's lowest idle speed. Heavy - means high quality Single 40amp rail - means it has plenty of juice to feed your power hungry components and handle OCing them. 120mm Fan - Better airflow, and virtually silent. Though I have not tested this thing at full load, I have no worries. Sleeved cables - adds a super nice touch

Pros: Bought it when it was on sale (black friday week) because the ratings were pretty good. More than enough power for my mild gaming system (see other)

Cons: The sleeving made it a little difficult to route cables in my Rosewill Challenger Case but it's all there and still working.

Bottom Line: More than enough to power a

5 out of 5 eggs Efficient Power

Pros: Not gold-certified, but definitely not bad.

Cons: None.

Bottom Line: At current price of $90 is overprice, but I got for les than half this with a sale and rebate ... which was honored. At that price it's a steal. I trust Antec power supplies.

1 out of 5 eggs Died A Quiet Death (Followup)

Pros: None!

Cons: Antec responded to my review and I was advised (as you can read) to call their 800 number to speak to a representative. Forget about it! After holding on the phone for more than an hour (I was held at number 3 "queue position) throughout the entire waiting time. What is the point of having people call your customer support number when you WILL NOT or CAN NOT answer their calls? You need to remove the telephone number and send us directly to your website.

Bottom Line: I usually am a very calm and easy-going person. But in Antec's case, I am absolutely furious! What in the heck happened to this once fine company? They need to clean up their act -- QUICKLY! Or, get out of the market.

1 out of 5 eggs DOA

Pros: Decent price if it works.

Cons: Dead on arrival. Since I have to pay return shipping on the RMA, the end cost of this PSU to me will have increased by almost 25% (plus the aggravation of troubleshooting and being without a working computer for a couple of weeks).

5 out of 5 eggs Solid PSU with great cable management

Pros: - Braided cable tubes
- Quiet
- Low Heat

Cons: None

Bottom Line: I had this PSU for 2 years before I started doing major upgrades to my machine that required a PSU with heavier wattage. The braided cable tubes are a godsend. My next PSU only had zip ties to bind the cables and I swore I'd never get another PSU that didn't use braided tubes.

Great buy and performed like a champ for me.

1 out of 5 eggs Died A Quiet Death...

Pros: I cannot give any "pro' comments on a power supply that died after just a little over a year.!

Cons: It worked quite well during its relatively short run. I purchased this PW on August 8, 2012. The other day, I turned my system on and nothing happened (except the motherboard light came on). I've been in the computer tech business for a long time. So, I immediately removed in and replaced it with another power supply. The system came right on, so I know the one in question was dead.

Bottom Line: Antec brand power supplies is what I used to swear by for reliability, as well as longevity. I guess those days are now over. Quite frankly, I'm disappointed and a bit angry that this power supply died so quickly after just a little over a year. Plus, I never used this computer that often or put any undue demands on it. It seems that no manufacturer (these days) can be relied upon to deliver *quality* products nowadays. Well, no more accolades about Antec from me to my fellow techies...

Manufacturer Responses:
