Computers draw very different amounts of power depending on whether they are idle or are under load. You could estimate the maximum power used by each of the components (CPU, motherboard, hard drives, graphics card, etc), but it's probably best just to measure it yourself.

The reason computer power supplies are rated for a maximum power consumption and do not state an exact current they will draw (unlike your hairdryer) is quite simply because power supplies are generic components and a server configuration is pretty dynamic (only CPU socket occupied or all, completely filled with power hungry 15k spinning disks or drive-less ...

I would get a Wattmeter and measure the actual power usage under max load. Modern wattmeters come with an array of functions, providing peak amp, average amp, total energy usage, etc. E.g. My machine has a 800W power supply, but it doesn't draw that much. I bought a meter when I decided to get a UPS. It turns out, powering my machine at idle load + one ...

First, that power strip cannot connect to a 20 amp receptacle. It is mechanically shaped to only connect to 15 amp receptacles. A 15 amp receptacle is significant power. Does not matter how many devices are powered. Relevant is the total current drawn that should not exceed 13 amps. Second, both a 1440 (actually 960 joules) and 4000 (actually 2700 ...

Short Answer With modern processor, with fast C6 (core/module power gating) capabilities, the difference in power consumption between the two power profiles is negligible. On the other hand, due to how different CPUs behave in power saving mode, you can lose considerable performance using the "balanced" profile. So I advise you to use the "high performance" ...
