Unnecessary gauges are all of the rage now with kids decking out their 1983 Honda Civic CRX's with a dashboard chock full of gauges, and now that trend can be brought home with Gigabyte's Visuals USB gauge. This gigantic and gaudy gauge actually has a purpose, unlike the ones seen on automatic transmission cars driven by teenagers. It monitors wattage, temperature and fan speed of the computer power supply. Why would you ever want something like this? Two reasons: if you are a bit green and care about how much power your machine is sucking or if you happen to be an overclocking enthusiast that needs to monitor temperature for the sake of the computer hardware.
