Summary: I have this PSU currently running these specs and peripherals (ALL AT ONCE) 2 500gb HDD, AMD Phenom IIx4 960T overclocked, 2 crossfire 6770s, 16gbs RAM, 3 500gb a piece external HDDs,140mm LED side fan, hyper 212 cooler master, and keyboard w/razer naga mouse. I have had no issues this baby can crank it out and remain silent. It comes with more than enough connects you wont know what do to with them (tuck, zip tie and tape away lol).
Summary: Quiet, efficient, and reliable. Everything you would expect from a reputable brand like Antec. Don't forget that it doesn't include the power cable, so you'll need to find one if you don't have one already!
Summary: Old power supply has been increasingly cantankerous by shutting down and restarting the system on it's own at extremely inopportune times. When I took it out, determined that it was not actually high enough on wattage to adequately power everything in the system. After installing this new one, everything changed for the better; Power downs stopped, and the system actually now runs quieter and responds faster to everything.
Summary: I needed a power supply to replace the one on my computer. I needed 3 SATA connections. This has 5. I was able to install it without any problems ( I am not very tach savy). It has 3 SATA connections on one cable and 2 on another. The power supply is very quiet- you can hardly hear it.
Summary: This power supply is perfect for any HTPC. For the last 3.5 years I have been using a noisy BFG 700w in my HTPC - total overkill. I upgraded my personal pc with a big AMD 6870 which required a bigger power supply. I figured I'd go with a quiet, green psu and swap my HTPC since I was not using 2/3 of the power available. WOW, what a difference. I can barely hear the psu when the house is quiet and never when I'm watching tv.
Summary: My original power supply (550 watt NeoPower) was supplied with the Antec Sonata Plus 550 tower case to house my A-bit IP-35 motherboard build. This is a very quiet case with it's noise shield panels but after 27-months of operation, the power supply failed. All of the proper voltages were present but there was no "good-to-go" signal on pin 8.
Summary: I purchased this to replace an ANTEC 450 power supply. I was looking for a close match since ANTEC also made my Sonata II PC case that holds this power supply. I made the replacement and it worked out fine.
