The power needed by our system is converted by The Coolermaster’s power supply. The RS 850 EMBA has an efficiency of over 80%, and stays high even at low power levels.
In order for our system to achieve average performance, we used the ATI HD3850 graphics card from Gigabyte. It is very economical in standby mode.
Our testing system is equipped with a 320 GB hard drive from Western Digital and a SATA-ROM from Samsung.
Overview of components and their power draws.
| Performance capacity of components | |
|---|---|
| Components | Performance |
| Cooler | 3.40 W |
| Graphics card | 4.75 W |
| Memory | 3.36 W |
| System cooler | 0.97 W |
| DVD-ROM | 1.60 W |
| Hard drive | 6.87 W |
All performance values were measured during system standby.

my media centre based on a 3700+ (S939, single core san diego, 1MB, 2.2GHz) only uses 56-58W while running rosetta@home! That's including 1.25GB DDR (3 sticks), a freeview TV tuner, and a 2GB compactflash card on a Seasonic S12 330W PSU. It's undervolted as far as it'd go though...
What about performance per watt comparisons, which would have been the best comparison you could have made in such an article.
If you had a system that consumed 300W of power (forget about idle and full load differences for this question!!) with a 500W PSU, what would your power consumption be for the purpose of energy bill calculation?
Am I correct in believing that the rating of your PSU is the maximum power it can supply, and that it only actually draws what the system asks for? So in this case, your overall system power use would be 300W?
So, if you install a much more powerful PSU than you currently need (for the sake of future SLI upgrades) you wouldn't be wasting electricity?
