Kill-A-Watt Results

Recommended Posts

I recently picked up a Kill-a-Watt meter to measure power usage on my servers.

Newegg had these up for $16.95 w/ free ship so I had to get one and take some measurements.

 

Here’s the results:

___________________________________________________________

Acer H340 w/ 1TB Grn 7200 WD Drive 0 & 3x2TB SG LP HDs >>62.5w

___________________________________________________________

WHSv2 Homebuild – Corei3 >> 65.2w

 

- SUPERMICRO MBD-X9SCM-F-O / Intel 2100 Core i3 CPU / 4GB RAM

- WD RE4 WD5003ABYX 500GB 7200 RPM 64MB Cache

- 5 x WD15EARS 5400 64MB Cache

- Antec Three Hundred ATX Mid Tower Computer Case +550W PS

- Fans: CPU Cooler + 3x120mm + 1x140mm

___________________________________________________________

Desktop Homebuild - Core i7 DeskTop >>> 87.4w

 

– Asus P67 MoBo, Intel 2600K, 8 GB RAM

- WD 500GB + 3x WD15EARS HDs,

- Samsung BluRay sata drive

___________________________________________________________

Rosewill 4x eSata box w/ 4xWD15EARS HDs >>> 34.7w

___________________________________________________________

MediaSonic 4x eSats box w/ 2x WD15EARS HDs >>> 15.4w

___________________________________________________________

Blackx Dual eSata Dock w/ 2x SG 1.5TB LP HDs >>> 15.7w

 

 

My main interest was to compare the Acer to my new v2 Homebuild. Everyone raves about how great the Atom CPU is on power and I expected to see a bigger jump in power usage on my new Corei3 2100 based server….. NOT, < 3w difference is what the meter tells me and I even have 6 drive vs 4 in the Acer.

 

Even my Core i7 DT system is not too bad with 4 drives and the 2600K CPU @ 87 watts.

 

I'm new to the Kill-a-Watt and the 1 page manual is scant at best, so if another reading is more useful please let me know.

 

Please post your results, I am curious what others are getting for power readings with similar system.

Just to ask and make sure.. Are you certain that the meter can accurately meter computer power usage? Due to the PSU, most cheap consumer meters give wrong results with computers..

BYOB regularly uses these to measure power consumption of systems from the wall. They represent fairly well (enough to matter) especially when comparing system to system or system changes. It measures total load from the wall so what ever the PSU is drawing(load) that's what it reads.

 

My VM server (project: One) consumes close to 70w now. The primary rig (project: Sabertooth) consumes close to 200w at idle, thanks to a recent GPU upgrade. Under load up to 450w.

You are 100% right. No CPU for me, only APU ;)

nice retort! I must say, the cooling fins on that board are crazy lookin'. Very interesting board with 802.11n and bluetooth on board.
