Did you bother reading the complete tech specs on Gefen's site?:
Note the line that says "Power Consumption". Why that disagrees with the "Power Supply" line I have no idea, but... that is what it is.
Note that there's absolutely no harm in using a power supply of greater wattage than your device needs (outside some edge-case exceptions), it's not going to "overpower" it. The problem comes when using a device that draws more than the supply is rated for. In that case it overheats it.
(As for the "edge case", in case you're curious: Some older "switching" power supplies won't work properly unless some minimum wattage is being pulled from them. This is hardly ever a problem now, but back in the old days if you wanted to, say, use an old IBM PC power supply on your test bench it might not work unless you tie a few resistors across the 5v and 12v feeds.)
