Mac Pro Power Usage

There are a few figures out there… I'm not about to tear my machine apart to get to a "basic" configuration, but here's how it breaks down:

2007 8x3.0 "Clovertown"
8x1GB FB-DIMMs
Bay 1: Western Digital Raptor 150
Bay 2: Seagate Barracuda 1TB
Bay 3: Seagate Barracuda ES 1TB
Bay 4: Seagate Barracuda ES 1TB
Optical 1: Pioneer DVR-112
Optical 2: Pioneer DVR-116
PCIe 1: NVIDIA GeForce 8800GT
PCIe 2: Empty
PCIe 3: Empty
PCIe 4: ATI Radeon X1900 XT

Idle, before drive spindown: 380ish watts
Startup: Spikes to low-500s.
Full tilt: Never tested, the only reason I borrowed the watt meter was to calculate how much money I'd spend not sleeping it.

 

Here is mine
2008 MacPro 2.8
Model Name: Mac Pro
Model Identifier: MacPro3,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 2.8 GHz
Number Of Processors: 2
Total Number Of Cores: 8
L2 Cache (per processor): 12 MB
Memory: 6 GB
4 Hard drives 2 opticals
NVIDIA GeForce 8800 GT
20" Samsung 204t
Mac Pro load 360watts
Mac Pro 20” LCD idle 280watts
Sleep 45watts

Mac Pro stand alone (4drives) 269watts load
Mac Pro stand alone (4drives) 200watts idle

 

and here's mine:

2007 8x3.0 "Clovertown"
2x2GB, 2x1GB FB-DIMMs
Bay 1: Seagate Barracuda 750GB
Bay 2: Seagate Barracuda ES 500GB
Bay 3: Seagate Barracuda 750GB
Bay 4: Empty
Optical 1: Standard SD
Optical 2: Empty
PCIe 1: NVIDIA GeForce 7300GT
PCIe 2: Empty
PCIe 3: Empty
PCIe 4: Empty

idle: 180W - 200W
load: 420W

@grue - i borrowed your machine template...

And grue, since we have the same batch of MP, am I to understand that the lower the ambient temperature goes, the higher the PSU temperature when the MP is on constant load...?

This is because my MP PSU temp hovers around 70ºC when placed under a table without proper ventilation, but rose up to 86ºC when placed on the table under a ceiling fan or when the room is air-conditioned.
