A single cpu 45nm Quad Core Mac Pro might not be too bad. It does seem like FB-DIMMs would be cheaper than 4GB SO-DIMMs.

Just got a power meter today £10 off amazon, bargain!), havent tried it out on my main system yet (the wall socket is behind a cabinet, right pain in the ass to get to), but my file server's power socket is easily acessable, so heres some numbers. I
Idle:A satisfying 47w.
Fully stressed:(x264 encode + HDTune benchmark both drives) 83w.
Streaming 1080p: 54w
Streaming SD Xvid: 50w


spec:
AMD Sempron LE-1640 2.6Ghz
ASUS M2a-MX 690V mobo
1x2GB corsair DDR2 800
2x 1TB Greenpower (4 platter EACS version)
1x 120mm scythe S-FLEX @ 5v
1x 92mm Scythe Kama @ 7v
1x Optical drive (used during installation, forgot to unplug after)
Corsair 400w HX PSU.

Not bad, but my motherboard holds me back somewhat from getting into the sub 40w area.
I got it cheap off a friend for £10 with the CPU on, its BIOS is as simple as they come, so no underclocking/volting. and the IGP uses more than the 780G chipsets. But at most i think i could bring this system down by about 5-10w, so not worth it in my book.
Not to shabby for a system that (minus HDD's) cost me less than £100.

main system:

ECS Mini-DTX 945GCT-D (cpu: atom 230; chipset: 945gc/ich7)*
(video onboard)
1X2GB DDR2 DIMM 533Mhz PC2-4200
160gb fujitsu 2.5" hdd
dvd-rw liteon
picopsu 120 + AC/DC power brick 12v/50w

OS: Windows XP SP3

*totally fanless, no case fan.

[+LCD 17" Samsung Widescreen]


power consumption (measured with kill-a-watt):

computer:

23w IDLE
31W full load
(simultaneously running firefox + ie, winrar compressing, everest on, reproducing divx video, emule downloading)

lcd monitor: 13w
------------------------------------

umpc:
acer aspire one (atom 270; 120gb hdd; win xp home):

16w IDLE
22w ish full load
27w charging battery

------------------------------------

atom systems have a good performance and low consumption (even with the relatively power hungry 945g chipset). Actually I would like to build a second pc with atom 330 (dual core), with slightly higher power requirements (but hopefully under 30w idle if carefully modded).
Power AC regulator consumes alone 3w. Router 6w. The led lamp on my desk is less than 1w).
I am so concerned for power consumption for ecological reasons and becouse the very high price of electricity here in Mexico.

Why not an AMD system? Is the Atom 330 cheaper?

atom 330 board costs 83 USD (+30 USD int. shipping). Less than dual core amd. Moreover power consumption idle would be higher.

I ask because my $60 AMD single core + motherboard is 18W idle.

very nice consumption. Would be fine for a nettop like mine. :)
Which amd cpu do you have? and your mobo?

is it the Foxconn A74MX-K (740G) + 800MHz Sempron LE-1250 ?

Here's my system and my friend's.

My system:
AMD Athlon X2 5400 2.8 GHz, Brisbane G2, Stock 2.8 GHz speed
4x2 GB G.Skill Pi Black DDR2-800 RAM, 4-4-4-12 @ 1.92V (1.95V is lowest available in BIOS)
HIS ATI Radeon HD 4670 IceQ Turbo 512MB GDDR3, 800 MHz core/1050 MHz (2100 MHz DDR)
2xWD6400AAKS Caviar Blue 640GB, 1 WD10EACS Caviar Green 1TB
Seasonic S12-330 (Sleeved revision)
Antec Solo with 1x120mm Yate Loon D12SL-12, 2x92mm Nexus, all at 5V
Scythe Ninja, Passive (may strap a 92mm fan on there for peace of mind... can no longer fit a 120mm blowing toward rear of case b/c of tall memory heatsinks)
Sapphire ATI Theater Pro 650 PCI ATSC TV Tuner Card
Windows Vista Ultimate x64 SP1

1.2 GHz, 0.768 V: 82W idle in Windows, heads still loaded on the Caviar GreenPower
2.8 GHz, 1.200 V: 174W peak observed running Grand Theft Auto IV, 206W peak running 2xCPUBurn and 1xFurMark.

My friend's new build:
Intel Core 2 Duo E8400, Wolfdale C0, Stock 3.0 GHz @ BIOS VID: 1.1125V, Everest: 1.07V
Gigabyte GA-E7AUM-DS2H w/ integrated GeForce 9400 graphics, Stock clocks 580/1400 MHz (GPU/shader), overclocked to 674/1624 MHz
2x2 GB G.Skill Pi Black DDR2-800 RAM, 5-4-4-12 @ 1.84V (not CAS4 due to BIOS bug that still hasn't been remedied)
WD3000BLFS 300GB VelociRaptor, Hitachi P7K500 500GB
AverMedia MCE A180 PCI HDTV (ATSC) Tuner
PicoPSU 120 with EDAC 110W brick
Antec SLK3800BQE with 2x120mm Scythe Gentle Typhoon (1450 rpm model) @ 9V, 1x80mm Nexus Fan @ 7V
Xigmatek HDT-D1264 top-down CPU cooler with Scythe Kama PWM 120mm fan.
Windows Vista Ultimate x64 SP1

58-59W idle, 98W peak observed running GTA4.
BIOS undervolt prevents dropping voltage at EIST idle, so it runs the same voltage at 2.0 GHz and 3.0 GHz. The 98W is just enough to turn the screaming fan on in the EDAC brick.

Motherboard: Gigabyte EP45T-UD3P

Memory: 2x 2GB DDR3 Patriot PC12800 1600mhz 7-7-7-20 (running 1333@6-6-6-18 1.9v)
HDD: 500GB Samsung, 1TB WD GP
Pheripherals: DVD-RW
Power Supply: Seasonic SS-330HB 330W

Metering Device: Kill-A-Watt

Bare setup: No fans and only 1 500gb drive
Idle: 71W
Load: ~100W (Orthos blend)

Stock CPU: +2 case fans
Idle: 76W
Load: 110W (Orthos blend)

O/C CPU 3.8ghz 400*9.5: +2 case fans, CPU @1.16v, RAM @2.1v
Idle: 84W
Load: 140W (Orthos blend)

Notes: Still a work in progress and will probably change as time goes on. The voltages are as low as I can go without crashing in Orthos. Summer is approaching so let's see if it stays stable at OC speeds. The memory was supposed to run at 1.9v stock but it wasn't stable until I ran it at 2.1v

Case fans suck! I found that a fan can use 3 watts easily. So a few of them can add up to a lot!
Intel stock fan rocks! It starts at a 775rpm and even at full speed of 1800rpm it's still quiet. The cheap plastic mount sucks though.
DDR3 ram But isn't DDR2 cheaper and has faster timings? All the reviews on the web about DDR2 vs. DDR3 ram when I was researching pointed out to articles that were two or more years old. Prices of DDR3 were 3-4 times what DDR2 were back then. So I think it isn't the case anymore. Timings has improved a little too. The only thing I never realized is that getting 2000+ mhz ram is not worth it if your CPU is not properly matched to it. Luckily the 1600mhz ram I got is matched to the E8500 when I overclocked it to 3.8ghz (400mhz) otherwise I was running it at 1333mhz at stock 3.16ghz (333mhz)

Hey, this thread has interested me, does any one know where i can buy a kill-a-watt in the uk reasonably cheap?

Thanks Mark19891989

I finaly got around to testing my pcs:

Desktop PC consumption

CPU E5200 @ 3.30 ghz 1.2v vcore
Idle 48W
Load 75W

Dual monitors: 62w combined

Server Power Consumption
Idle 58w
Load 89w

edit:Changed the motherboard in desktop, and overclocked more to 4ghz, low load power usage is : 116W, but its not silent any more :(

Idles at 44-46. Seems high for what it is.

Next move is to PICO powersupplies.

Sceptre 20 inch monitor uses right at 50 watts with brightness turned way down.
The 2Wire router/modem uses 22 watts by itself. I think that is too much.

Since it has been stable for months I feel now confident to post it:

Case: just an empty old case
PSU: picoPSU 120W + EDAC 110W AC-DC adapter
Motherboard: Asus M2A-VM HDMI (690G onboard)
Cpu: 4850E
Ram: Kingston Valueram 1GB 800Mhz DDR2
HD: WD 2.5" Scorpio 250GB
Additional nic: tplink PCI 10/100 eth
Tv tuner: Asus P7131H
Card reader: trust cr-3400 (all cables are loop through except the card reader usb, connected only on-demand)
Fans: cpu stock fan (motherboard managed) + 2 x 80mm standard coolermaster fans (@5V)

CPU management: CrystalCPUID (0.800V/1.0GHz - 0.800V/1.4GHz - 1.125V/2.5GHz)

Idle: 33W (card reader usb not connected)
CPU max load: 70W (the max I've seen with orthos, "typical" application full is around 65W)

Under 24x7 load (router/firewall) : 34W
Watching TV: 40W (the tuner seems to add +2/3W idle, +6W as tv tuner - just an estimate)
Without additional nic, tv tuner, card reader it can idle at 28/29W (0.8V/1.0GHz).
Peak reached during os install (CPU at default, 1.250V/2.5GHz): about 100W

For a camera application, we were looking for a compact , low power PCI express x4 platform. At the time of selection, the POV MB330 ION-ATOM seemed the only platform available (intel arrandale and atom pineview were not released yet) providing these features. We did the following power measurements:

MB : Point Of View, POV ION-MB330 (miniITX, atom 330 + ION chipset and PCI express x16)
http://www.pointofview-online.com/showr ... duct_id=97
SSD: Intel, X25M-160 G
MEM: 1x 2GB SODIMM PC2-5300 (667MHz)
PS1: Deer/Allied DR-8250SFX (POV ION-CS330 system came with SPIRE/APEX case with PS1 installed)
PS2: FSP90 (90W, Pico-like PS)
measurement device: Voltcraft Energy check 3000 @ 230V

Power with XP running idle:
PS1: 28W
PS2: 20W !!!!
PS2: 22.6W (2 x 2GB SODIMM PC2-6400 (800MHz) )

Now with frame grabber installed (also idle): Dalsa X64 Xcelera-CL PX4, PCI express x4
PS1: 37W
PS2: 30W

I exprerimented also with other supplies. The results can be found at:

Conclusion:
* (FSP) Pico PS significant more efficient, especially at lower powers.
* 2G additional memory draws 2.5...3W more
* POV MB330 ION-ATOM with 2 Gbye memory combined with a pico PS consumes < 20 Watt idle !!!!!.
The POV MB330 ION-ATOM (cost around 120 euro) makes it possible to build a small/compact, low priced, low power ( < 20W !!! idle with pico PSU ) system with PCI express x16 functionality.

:shock:

...

Just finished building my new i7 computer, and I was shocked to see the power consumption. I, like many people here, hate to see people on forums recommending 600W power supplies to run dual-core, mid-power systems, so imagine my surprise when I checked my Kill-A-Watt last night...

410W load (Prime95 + Furmark)
~295W CPU-only load (Prime95)
160W idle

I wasn't too surprised by the high idle power consumption, but that load power consumption really surprised me. I have a Seasonic S12II-Bronze 430W, so no chances of overloading the power supply (computer's probably only drawing 340W DC), but it was still pretty shocking to see.

By the way, I've never heard a Seasonic power supply ramp up its fan so much during load.

Specs:
Intel Core i7 920 @ 3.8GHz, 1.25 vCore
Gigabyte EX58-UD3R Motherboard
OCZ DDR3-1600 Platinum 7-7-7-21 @ 1.64 vDimm
XFX Radeon 4890 @ 900/1200 Core/Mem
Auzentech X-Plosion DTS
ASUS Blu-ray Reader/DVD-RW
Western Digital WD6400AAKS
Antec P183
Scythe Mugen2 w/ Slipstream
(2) 120mm S-flex 1200rpm @ 5v
Scythe Kaze-Q fan controller
Seasonic S12II Bronze 430W

On a side note, I have no qualms about the noise level of the computer in idle. When in load, however, the Seasonic ramps up. Sounds louder and more annoying than an S-flex 1200rpm at full tilt. I originally had the motherboard taking care of the Slipstream fan's speed automatically, but it was too loud, so I plugged it into the Kaze-Q and now I control the speed manually. Not sure about the voltage, but it's not nearly at the top of its speed range, and it keeps the i7 below 85C during Prime95. Idle temps are around 50.

my mediapc/server

motherboard Asus P5KPL-AM iG31
CPU: E5200 @ 2ghz (no point goin lower as the motherboard wont let me lower the vcore!! this underclock only saves me 10w at load, not sure if its worth it.)
HSF: mini ninja, + AC 8025pwm fan
RAM: 4gb ddr2 800
HDD: Hitachi DeskStar 1TB 7200 (the loudest part in the system by far, i have it on a piece of polystyrene to stop it touching the metal case, but i can still hear the ocaisonal seek sound)
GPU: GeForce 7300 GS
PSU: picopsu 150XT + Dell DA2 220W

power consumption
Idle: 45W

load watching a 720p video,a few torrents and runing mprime on both cores: 70w

idle and load measured using a kill-a-watt

im sure i could go lower if i brought a better motherboard with intergrated nvidia gpu, and more the ability to undervolt the cpu

edit: replaced the 1tb hard drive with 2*1.5tb samsung F2s usage whilst folding and watching a 720p video is 68w ,

2 hard drives
2 800MHZ 1 gb Corsair RAM sticks

55 Watts at idle
137 Watts at load (transcoding DVD to x264)
CentOS 5.2 64 bit

Using NSK-1380 stock power supply (380 watts I believe) using a kill-a-watt

I am soon going to upgrading to a Phenom 9550 quad core (95 watt), I am very curious how much power it will draw at idle and load...


have you upgraded your system to a Phenom quad? If so what is the new power consumption figures?
Thanks.
