If so, the max power on the power supply or chassis will give you absolute max. 80% of that number is what it is rated for on a continuous basis, 100% is for max burst. If you need a more accurate number (as the above is the rated Wattage, which /will/ be different than actual usage for safety purposes), you could run multiple of something like this: `dd if=/dev/urandom of={somefile} bs=1024k count=1024`. Depending on your processor speed, that won't keep the disks busy all the time which is why I suggested multiple running at the same time. What that will do is pull 1GB worth of random data (stresses CPU) and writes it as fast as possible to the disk. Running a few of those in a loop should give you enough time to see actual power draw. Shifting bits around in the memory register probably won't add too much power draw, as it is mostly CPU and chipset (just CPU if you are using AMD). The RAM stick is fully powered regardless. Hope that helps at least a little. -- Timothy Selivanow <timothys at easystreet.com> Linux System Administrator EasyStreet Online Services, Inc. http://www.easystreet.com
