Low power CPU

[dave28]

So like many people here i imagine, i have a pile of spare parts from changes / upgrades / etc etc.

The thing is i dont want to sell them because i would only get a very low amount considering what they cost so thought i might just build a 2nd PC.

I have seem to have everything except motherboard and CPU. ( i wont be using a dedicated GPU )
The case is a mid size tower desktop.

My main PC is quite power hungry so my idea is to make a very efficient and low power PC.

My problem is the CPU i guess.

Ideally i would have liked a CPU that is ultra low power like 15w or something but i cant seem to find any.

Most seem to be 65w which is not high i know but i just like the idea of ultra lower power as an excuse to build a 2nd PC.

So can anyone think of a cpu / mpbo combo that would fit a mid tower desktop

Any CPU can be super power efficient. Just need to set low voltage (1.0V and below) and low clocks (below 3.5GHz) manually. So that slightly narrows your choise of motherboards to something above low-tier, need some overclocking functions to be present in BIOS.
No dedicated GPU means it pretty much has to be Intel. Or AMD APU.

Alternatively, simply setting low power powerplan in windows would keep most modern CPUs at idle clocks and under 15W consumption.

I had not thought of that, i will have a look into the powerplans effects etc.....

What do you want to use the 2nd PC for?

just browsing internet, forums, downloading

dont need any gaming or anything that needs grunt

i wouldnt bother building one but i have most of the parts and as i say, i dont really want to sell them since they wouldnt be worth it

thanks guys, it makes sense that if your just doing light tasks that CPU is not going to burn much power so its probably a silly idea that i got into my head that you need some ultra low TDP rating
