ok I have an e2140 cpu that was bunndled with an asrock 945gc motherboard I was planning to uses these in a home server power usage is a major factor is this ok ( with the right psu either a 120w pico psu or a fsp/seasonic 250w number ) or should I change for an atom setup the system would be running WHS the only reason I want to use this motherboard is that it has 4 sata2 ports where as all atom motherboards only have two ( so far ) I wish to have the abbility to add a extra HD when nessesary thank you in advance
120W could be fine, but only if you used onboard graphics. It'd be pushing it a bit, though. A PicoPSU doesn't even have an 8- or 4-pin CPU power connector, right?
the higher wattage ones do as it is reqired for some am2 and 775 mini-itx motherboards i have found a pico psu type that is 140w below is the amps and watts for the various voltages as it would be running whs there would be little or no need for anything more powerful than the built in graphics card. 12V 7A 84W 5V 6A 30W 3.3V 6A 20W 5VSB 1.5A 7.5W -12V 0.05A 0.5W Permanent Power 84W Combined Power 142W
+1 on underclocking. E2xxx series CPUs have a TDP of 65W, that's already half of the PSU's capability.
I have been able to underclock the cpu plus I have found a 190 watt version made for the mcubed range of cases
