Help with calculating Watts for Overclocking...

post #1 of 7
Thread Starter 
I want to know how I can figure how many more Watts my Overclocking is going to be using, based upon Voltage Bumps above Stock...

Basically how can I calculate wattage based upon a given voltage amounts.. (anyone?)

Or is this not possible?

There's no way to really calculate that. But you're going to be fine.

You can buy a wattage meter at the socket, and OC the cpu and compare before and but you have to calculate the efficiency of the PSU as well as the accuracy of the meter and then think about anything else that could pull more power during OC.

Zalman is going to release a meter that allows you to monitor the wattage pull at the 12v 8pin connector for the CPU power. You can build your own b/c there are a ton of chips that just monitor current.

I have a similar question. I bought a Kill-a-watt to measure my power usage relative to my PSU's maximum. Browsing the web now, it only seems to be using ~90W. When I used an online calculator to figure out what PSU to get, I could have sworn it predicted that the parts I'm using would draw more power than this.

Does it increase dramatically under load? It seems strange to be using <90W when I've heard that 650W might not be sufficient for a dual SLI setup.

well under no load your system will consume much less. Run IBT with maximum memory and then run furmark and you will see what shows up.

Your i5 and all of the Core i Series processors use little power while doing basic task like browsing, reading files, etc. so what you are seeing is a powered down reading most likely, if you want to see what the PC will pull with voltage bumps, you are going to need to stress it, and compare results vs stock against the voltage bump with your meter.

Use LinX to fully stress your system, this is the one program that can definitely do it! Bare in mind this will NOT stress your video card, so you won't get a full 100% reading, you can download a Video Card Benchmarking Tool and run that while running Prime95 (3 cores instead of 4)... With 1 core for the GPU and the GPU at max you should be able to get close to full stress load...

MSI Combuster Will stress your GPU...
