Cutting the cost
A gaming rig only pulls serious power under load, so turn on sleep and power-saving profiles for idle time and browsing. Cap the frame rate when you don't need every last one; the graphics card eases off and draws less. Try not to leave it grinding through downloads overnight unless you must, and switch off at the wall to kill the standby draw from the tower and monitors.
