    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 ... Read more

    Hasn't worked great at all

    Antec must've got a bad crop of these in -- it's taken me more than a month, but after going through two different motherboards, and various other components, I found out this PS was faulty. Constantly reboots, sometimes after a few minutes, ... Read more

    5 out of 5 eggs Still working!

    Pros: Still a beast after 4.5 years. Hard to believe it's been that long. Definitely got my money's worth.

    Cons: None.

    Bottom Line: It powers a modern mid-range gaming rig, including 3 HDDs and 1 SSD.

    5 out of 5 eggs Great power supply, works like a charm 4 years later

    Pros: Great power supply, got it four years ago for $49. Its affordable, from a quality brand. The cables are nicely sleeved and the construction is solid. Its very quiet and the 80+ Bronze rating is a plus. For the price, I could not have asked for a better PSU at the time. Four years later, its still running perfectly.

    Cons: The price went up to around $64 at the time of writing this review. At that price point, it ceases to be competitive priced IMO. There are better options for over $60 from other reputable brands.

    Bottom Line: Overall, I would recommend this power supply, as long as you get it for a good price.

    5 out of 5 eggs Nice PS

    Pros: Good Power Control and response, Plenty of Juice, Quiet, Nice Cable Lengths in full size ATX case, and all around outstanding.

    Cons: Can't think of any?

    Bottom Line: Put this PS in a ATX gaming case with an AMD 3gh 6 core water cooled CPU, Video is dual crossfired Radeon 4870''s, 8 gz of ram, and ASRock 970 Extreme4 MB. Runs it all very smooth, would definitely buy another and most likely will when I next upgrade my system and pass my old one to my wife :)

    5 out of 5 eggs It's working

    Pros: Thing works, what more do you want. I never hear it, but how could I over my loud ash CPU cooler.

    Cons: It's not modular, but you knew that.

    Bottom Line: None really. I don't like how it vents to the bottom, but I just put it on a flat board since I have a carpeted floor.

    5 out of 5 eggs 3 Years and still going

    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
    Amd 720 3x BE OCed to 3.4ghz
    Asus Radeon 7870 slightly OCed
    Sabertooth 990fx mobo
    2x WD 500g HDs
    LG Dvd RW drive
    2x gskill 4gb sniper series
    4 Case fans/Hyper212 fan.

    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.

    On weekends it's opened all day long... no problem since day one!

    Cons: None so far because it still works after two years!!!

    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.
