im building a plex Server
can you name any good CPU's with a good TDP
wich may work or not with this Motherboard: Asus Z87 Deluxe
Get an i7 4785t.
that look stupidly good for 35W
c2750
Intel Xeon E3-1230V3, of course a bit higher tdp, but 4 cores 8 Threads goodness.
ASRock Intel Avoton C2750
got one does not get past the grub menu gave up on it
why is tdp an concern ?
With a decent cooler, there shouldnt be any i guess.
power cost
But TDP is just heat output, it does not realy tell that much, about power consumption.
it is more power you need hotter it's going to run so colder it runs les power it uses
AMD Athlon 5350 Quad-Core 2.05GHz @ 25W?
No!
TDP refers to the Maximum power that the CPU can draw.
There are two things you should care about for a server build; Idle power consumption and efficiency.
Idle power refers to how much the system draws to just maintain the Operating System. Generally, ALL of the CPUs in a product family have EXACTLY the same idle power draw. IIRC you'll find that the Intel Pentium G3258 idles the same as the i7 4790.
Remember, Things like your power supply and motherboard will often cause more of your idle power consumption than your CPU. This can be solved by choosing carefully here.
Efficiency refers to how much power the CPU needs to perform an operation. Often, better binned CPUs will often complete more operations per watt (such as the 4790K. You can limit the power this uses by limiting the frequency in the operating system or BIOS.
nope
TDP is just heat output. aka Thermal Design Power.
Its a number measured in Watts, on which your cooling solution must be capable to dissipate from the cpu.
It has basicly nothing to do with how much power a cpu is exaly using.

cant rma it?
i love my supermicro one
a 120 watt TDP CPU's max power consumption under full load is generally going to use in the ballpark of 120 watts, plus minus some percent.
99.9% of all the power it uses is going to be turned into heat, which needs dissipation, that remaining 0.1% is so small, it might not be there but its radio interference that the CPU makes, don't pay attention to it.
watt cpu due to how they make the heatspreader, later intel CPUs are harder to cool because they use shitty thermal paste between the silicon and heat spreader instead of soldering like they used to.
TLDR TDP = POWER CONSUMPTION = HEAT.
all are the same.
ehm nope, you are a bit wrong exaly.
It has totaly nothing to do with that.
Or atleast not directly.
Maybe this help you guys understand TDP.
Like i said again TDP is just heat output.
It basicly does not say anything about how much power a cpu is exaly using.
Erm yes,
A 65 Watt TDP CPU when running at full load (Floating + Integer + RAM + all the other instruction goodness) is going to make 65Watts of heat, and draw 65Watts from the power supply (approximately).
BUT: Your CPU rarely runs at full load. A router, or home server, etc will sit idle most of the time, or just be running some simple encryption. Then the Maximum TDP not really important.
If you take the i7 and an i3 and run the same load on them (say transcoding video for streaming over the network) each CPU will use approximately the same amount of power as they are both doing the same amount of work. The i7 would generally be the better binned part, therefore have more overclocking headroom, and therefore its transistors probably use a little less voltage than the i3's and would use slightly less power for the same amount of work. At this level its really luck for nanoWatts of power savings.
TDP is just heat output, nothing more nothing less.
i allready given an explaining video.
A 5960X will consume allot more power on load then just 140W.
If you already own that ASUS motherboard, then the Xeon E3-1231v3 ($209 at microcenter) is probably the way to go to save money.
If you don't own that motherboard, don't buy it for a server system. It will work, but it doesn't support ecc RAM, which you'll probably want if you want to keep your data from getting corrupted over the long term.
The Intel Atom C2550 exceeds the recommended requirements for plex.
If you're going to have multiple users streaming at the same time, then you may want to go with the Xeon. The Haswell chips are fairly efficient. My i5 system without a gpu pulls less than 45W from the wall at idle (including 4 fans, keyboard, SSD). However, an atom processor system would use about half that IF you have a power supply that can run efficiently for a low power draw.
