Normal
I get how it works...heck it's not kept power by the usb. If it needs the power on pins (mobo header and case switch wires) to go through the thing and still needs a tap from the ATX connector...the USB isn't kept powered...the iMon gets powered from the ATX connector...in your case the BTX connector :idea: Why not buy a normal ATX pass through and patch/tap it or buy a pre-tapped one?
