consider when buying your next powersupply

[Steve]

i always new that there is a huge misconception about how much power a PC needs, but i came across a thread elsewhere, where specs and wattage has been recorded, the results were more suprising that i thought.

looks like the gfx card is the biggest factor, but still i think psu manufacturers have been misleading people for a while?

here's some examples

1x 200mm, 4x 120mm LED case fans
1x DVD-RW
Hiper 630w PSU (recent 85% efficient model)

And all of that draws...

idle with just 1 gfx card is closer to 120w

laptop by comparison full load 85w (3400+ clawhammer, 9700 mobility, 17" screen max brightness) idle of ~30w



the list goes on.

i can see several outcomes if u read this.

1 you don't care at all either way

2 you will save yourself a nice amount of money on your next upgrade

3 you actually pay the electric bill yourself so you might buy a more efficient system for example the system with the following setup consumes just 53 watts when the system is runnning


* Intel® Wolfdale E5200 Dual-Core, 1.2GHz/2.5GHz (1.08vCore)
* Thermalright Ultra 120 Extreme (Passive)

* ASUS P5Q-EM microATX Motherboard (Intel® G45 Express)
* Integrated Intel® GMA X4500HD Graphics
* Seagate Momentus 7200.3 80GB 2.5" Laptop Hard Drive
* Western Digital 1TB Caviar® Green™ 3.5" Desktop Hard Drive
* Sony DRU-190s 20x SATA DVD-RW
