Great value for the price, very impressed by sound level and heat generation. I used this to replace an older 400W Antec power supply on my primary, den computer which is on almost 7x24.
With the previous power supply, I had to close the heating vent in my den during the winter to help manage the room temperature when the door was closed. With the new power supply, I've actually gotten chilly in the room and had to re-open the heating vent! Heat generation is generally directly related to energy usage, so I'm anticipating a drop in electricity usage from the new power supply. I will now be looking at upgrading the power on my other two desktop computers!
