Sadly, many people who purchase a power supply for their computer buy the cheapest one they can find. This can be a costly mistake.

This is a great power supply, it has a 41A single 12v rail so it will provide clean, consistent power.

works as advertised none This PSU caused me a very frustrating week of troubleshooting! I really wanted to like this seemingly well-built unit from a reputable manufacturer. Really great keyboard, Looks good, functions very well, The next step up is mechanical from this thing, great keyboard all around.

This is a fantastic power supply that runs quiet and is very efficient. It can handle any load you throw at it without skipping a beat.

Others have done a thorough job of detailing the quality features of this PSU, so anything I could add in that sense might seem redundant. . At first I was weary of the Corsair brand, but after reading a few reviews, it seems everyone was spot on.

This makes it one of the most efficient PSUs available
Corsair VX450W was found to be a very robust power supply In terms of noise and efficiency, the Corsair VX450W power supply got high scores in our books. - Legit Reviews, August 2007

Low Noise

Low Heat Generation due to efficient circuits 120 mm Double Ball Bearing Thermally Controlled Fan
Allows for quiet yet high airflow

~21dBA at up to 90% load

About the sound of a whisper
Oversized thermally controlled fan Free flowing venting
It's among the quietest fan-cooled PSUs we've tested. They are very energy efficient, matching and even surpassing many of 80 Plus certified models we've tested. Silent PC Review October 2007
Clean, Reliable Power Value Price
Rated at Continuous Wattage at 50C
highest +12V rating in its class
Active PFC with a PF value = 0.99 High-quality Japanese components
Means years of reliable service
"As we've seen from the load testing numbers and ripple, Corsair has it going on with the new VX550W. Stability - check. High efficiency - check. Ripple well in hand - check. Build quality - it doesn't get much better. Good value - at around the $100 mark I sure ain't complaining -JonnyGuru- August, 2007
