power consumption

Mr-White · 16 May 2009 at 12:09

After recently buying a shuttle and realising the limitations of components due to the power supply it has got my checking the power consumption of all my upgrades. I also picked up a cheap power meter from a certain local electronics store for £8. I'm currently in the market for a new gfx but thought this would be an interesting thread to find out the actual power usage from each spec and the psu that's being used.

ok here's mine

Shuttle SG31G2
e6600 @ stock 2.4ghz
2x 2gb memory
1x 320gb hdd
dvdrw
250w shuttle psu (soon to be a 300w)

with onboard intel gfx 128mb (can be set upto 384mb max)

65w idle
85w load

with ATI x1550 256mb

85w idle
115w load

with ATI x1650 512mb

idle 85w
load 130w

next will hopefuly be an 8800 GTX

The 8800GTX will bump it up a lot, I'd imagine. They are quite thirsty IIRC.

Dont forget 2 things, firstly the plug in power meter measures power draw at 240v (well 230 these days). Your PSU is not 100% efficient, so at full load 250W, you should expect the meter to read around 315W.

Secondly, be carefull not to exceed the rated 12v amperage, should be printed on the PSU's label.

PS, I dont normally see my Q6700 + 8800GTX exceed 250W on my plugin meter, and I have a stack of fans, several disks, zip/floppy/fan controller, a bunch of usb devices etc. You should be able to get away with the GTX as long as the 12V rail can handle it.

You you need the extra power because of the gpu you can buy a small 250w powersupply for it.

Mr-White · 16 May 2009 at 12:40

The amps was my next worry after the wattage. These 2 PSUs are 70% and 72% efficient at 100% load

current PSU

new PSU

I was hoping other members would post their specs and power consumption too

300w PSU isn't going to power this system if you have an 8800GTX installed...

This thread was more about computer specs, psu size and power consumption

I started another thread here with regards to my gfx search

I can't remember exact numbers now but mine was around the 400w idle mark going to nearly 600w under load.
