This tool will
finally answer
everyone's question:
"Is 150W enough to power my system?"
These guys make a product called
Watts Up? and it allows people to instantly measure how many Watts are being consumed by any 120V device. You simply plug this inbetween the source and the device and it reads out the power used, cost, and a bunch of other nice facts.
They have two versions, the regular and the Pro which has a serial connection to transfer data to your PC about power consumed over a period of time. The price is a bit steep but I think it will aleviate everyone's fear of whether 150W will be sufficient to power their PC rigs.
Anyone used one of these before? If I end up buying one I'll post some results.
