| calculate CPU power consumption
I currently own an Antec Slimline desktop MINUET II Black/Silver Steel MicroATX Slim Case Computer Case with 220Watt Power supply.
I am trying to put a old P3 micro ATX. its good to go.
Now, I am trying to calulate the power consumption.
I only have the intel pentium III 550 fcpga with 256ram and 1 10gb 1cd-rom, no floppy, with on-board VGA, 4usb ports and 1 NIC.
what is the power consumption? Is it lower than 100w? The case provides 220w. Will the power supply load 220w at all times or, only what the computer has all running, such as 100w?
I am worried about my electricity bill. I want to have this guy as low power consumption as the best I can. Or I may try to buy a even lower power supply as well.
what's yr suggestion? |

| It should definitely be drawing well under 100W at the wall. When idle, I'd expect under 50W.
The "heavy" hitters in that system are the CPU (15W), hard drive (15W), and the CD-ROM (25W). There's also a few watts for the memory, chipset, and perhaps 10% loss for the voltage regulators on the motherboard. Those numbers are assuming full throttle operation.
The PSU only supplies what the components need so there's not much power being lost. |

@mindspring.com | thanks.
I am using this as a m0n0wall firewall. So I am trying to get low power as possible.
so you are saying that if full load only takes 100w, the power supply only provides 100w not full 220w, rite? |

mm...if I put the CF memory than the regular hard drive, will the power consumer much less?
I can't find any article regarding the power.
Thank you. |

clubs: | Sure, but it's not worth doing so to shave off 15W. Electricity is cheap and you'll take a huge performance hit by using CF. |
