The power consumption of an OC computer

[TheArchon]

Will it increase once i OC my comp??

Any advice about OC my Gigabyte K8NF-9 mobo, with duel Giel 265 3200 ram, Venice 3000+, GIgabyte XFX 6600GT, HEC Compucase 6A19 with 400W ATX 2 power and Akasa EVO33 cpu cooling.
Where do i begin, is OC mobo specific? or CPU?

 

[fishmahn]

yes. Linearly to the increase in clock rate and vCore I believe.

The mobo should have OCing features.
Because you could have the same CPU as other person, but if you don't have the capability to modify the FSB, the voltage,and the multiplier you're not going to be able to OC.

Read a little in the forums in the overclocking section

Power will increase lineary with clockspeed, and to the power of two wih vcore. so yes, power consumption will increase significantly (depending how far you push it).

power of two wih vcore

So, does that mean a 10% clock increase (vcore same) is 10% more power (say 88 instead of 80w), but a 10% vcore increase with no clock change is more than that? How does that work? I would have thought that going from 1.5 to 1.65vcore @ 2.0ghz would have just been 10% more power.

Yes.

Yep.

Overclocked Watt = Default Watt * (Overclocked Mhz / Default Mhz) * (Overclocked Vcore / Default Vcore)²

Please note the "²" (squared) at the end.

power P = (V)^2 / R

V=voltage
R=resistance

There is one factor that can alter this. Your right on the money, and im not arguing about the power consumption. There are places everywhere that have what many refer to as dirty power. As dirty power increases all sorts of bad thingys also increase but at a faster rate than the power does. The other thing that is common with dirty power is that as more of it is consumed, the bad aspects that increase sometimes have a negative impact on the actual usable or clean power that makes it to the unit. What does this have to do with the discussion? Probably not a damn thing :tongue: but I thought it was a good place to mention it. I think that many people have this issue and are not aware of it. Its so bad in my neighborhood that I run three UPS units that are rated from 550W up to 850W. If I didnt, I would lose a tv and computer at least once a week.

True, but how does resistance scale with clockspeed ?
Apparently, lineary
