While some of the values in the table are right/within the ballpark, some are WAY off.
Clock radio having an average load of 100 watts is insane. My over 25 year old clock radio when I plug it into my Kill-A-Watt doesn't even register as 1 watt, to my pleasant surprise. I have 5 other newer clock radios in the house to make the place sound occupied when I'm away and they have tiny AC adapters. I plugged in my power strip that has those 5 clock radios on it into my Kill-A-Watt and it registered as a 1 watt, in total.
The computer values are way off unless one is building a very power hungry gaming machine w/multiple high end video cards. My not very efficient ancient i7-860 machine w/1 SSD + 3 rotating hard drives all running, idles at under 70 watts. I don't recall power consumption reaching more than double if i max out the CPU and GPU by running benchmarks. If I turn on my 2 not very efficient LCDs (20" IPS and a 24" IPS), my total draw w/the LCDs is about 164 watts.
I have an LCD for use w/my security camera system that is way more efficient.
I used to use a 21" CRT monitor long ago and I posted this elsewhere:
Sony GDM-500PS 21" CRT monitor:
- 2 W in standby
- 93 W when in WinXP at desktop w/default background
- ~115 W when displaying an all white screen
I put together an i5-2500 machine for my dad, and IIRC, it idles at under 30 watts.
TV at 300 watts? Way of, as well. My former 27" CRT wasn't that high with an all white screen. I have an old Samsung HL61A750 DLP RPTV w/3 LED lights (no color wheel) and the figures at http://www.avsforum.com/forum/63-rear-p ... d-faq.html
sound about right. I run mine in low or min.
User chuckolson made these measurements with his Kill A Watt P4400 Tester to show how power usage depends on LED control setting:
Auto 170 - 190 W.
Max 170 W.
High 140 W.
Medium 119 W.
Low 99 W.
Min 84 W.
