of course it can
just make sure you dont get the Frost Blue or the Diablo III

both are usb powered

There is 2 versions of USB
Siberia V2 USB which is a 3.5mm jack headphone with an external usb soundcard
Diablo III and Frost are pure USB headset means that the soundcard is integrated
D3 and Frost SC offers noise cancelling mic feature than the normal USB soundcard
but the normal SC let you choose whether to have stereo or 7.1 while the D3 and Frost stays 7.1 whether u like it or not
