I need to reduce the load on the 15A circuit my computer is on. I have a 220 volt AC outlet in the room, will this http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=corp&sku=a2894900 work with my PC Power and Cooling S75QB 750W supply? the sticker on the psu reads 100-240 VAC, although there is no voltage switch. has anyone done this? I do not want to meet my local firemen.
