yes mate it is 550W, Its a multipurpose system. Its a Quad Core PC that is also used for watching and Editing HD videos using a HD graphics card, So its good to have the power there.
its great cos it runs flawlessly at all times, even if I open it up to loads of applications at the same time. but when I came home today I could hear it running and it got me thinking to how much power it is using.
If I bought a PC with the spec to run the cctv
, say 200watts then I'm guessing from the above comments I will already be saving money.
