Hi, I went to a different angle of attack on power usage.
I Have a nice I7 desktop that I was using for everything. I now use it only for working with Video, That is Capture, encoding, Authoring and Burning of BluRay disks.
For everything else I am now using a Lenovo All-In-One Desktop computer. It is only a little bigger than than a 22" monitor would be. I use this for Internet and everything other than working with Video. I got this one for two main reasons. There is a Lenovo Authorized Service Provider approximately 10 to 12 miles away if I ever need warranty work. Other work after the warranty expires I can download the Service manual and do myself. It was Intel based, Not AMD (personal choice). It gives off very little heat. Once I installed "Classic Shell" for windows 8, Malwarebytes Pro and a decent Antivirus It was good to go.
The best part is a decent screen size, And it's power supply (External) is only rated at 120 watts so I'm pretty sure it is using less.
My other choice was to keep using my Laptop, The 22" display vs the Toshiba's 15" won out. The laptop would have used 1/2 the power this uses but screen size won out. Plus the laptop speakers were not cutting on YouTube.
