I have an E45 (uh... at home... doesn't everyone?). Anyway, I was concerned about my electric bill. I got a clamp meter (Fluke was the brand) that measure current. It draws about 5 amps at 220V, or 1100watts. This is a single rack with two drawers of 9337 disk, the internal QIC tape drive and a 7208 style, dual drive 8mm tape. Maybe that will give you a benchmark. In my neighborhood, the juice costs about 14 cents per KwH. I figure this beast costs $110/month to keep running. As you can guess, I don't turn it on unless I need it. I also have a rack full of boxes - a 170-2289 (one box, 4 disk drives, internal tape), 4 PCs, a couple routers. That whole rack draws 5 amps at 120V, or 600watts. I measured one of the PCs (P4-1.8GHz). About 100watts with the monitor turned off. Backing into a number, my 170 draws about 200-300 watts. Your 270 is probably in that ball park. The only way to really tell is to use a clamp meter. The specs you typically find will be aimed high for cooling planning. ++++++++++++++++++++++++++++++++++++++++++++ Go... FASTER! Without an upgrade!

Part of the information I am trying to provide is the difference in power consumption and cooling requirements for the 270 vs. the F50. I can't find the planning guide or any information on IBM's web site for the F50 anymore. (small wonder since the machine is what over 10 years old!!!) Does anyone know where I might find some information? Thanks Jim Oberholtzer
