If you check my signature for my Download station, you can find some numbers there, i use a 2100T + Intel H61AG + picoPSU 150XT with 150W brick, and even under prime95 it doesnt break 50W, now ivy bridge is more efficient and you using intel mobo so it should be safe to assume it should consume slightly less, also no hyperthreading, you will run a single ram, i also run 3 fans, so yours should be lower than mine.
Personally if i would have known my consumption in advance, i would like to have tried a different combo
For DC-DC: PWR-PICOPSU-90-XLP
- Greenest DC-DC ATX PSU to date.
- Ultra low power Standby consumption (<0.050 watt)
- High efficiency in the low (5-15 watt) and high power range
For AC-DC: 60w (12v/5A) AC-DC Power Adapter with Power Cord
, They advertise it as the "High efficiency, level V" the only one i seen level 5 sold from them.
Since my setup never draws above 50W, yours shouldn't either, so thats the combo i would recommend. The brick is in stock, but the picoPSU 90 XLP is not, but there are other sellers of picoPSUs, for example PicoPSU 90 XLP + 6.6A/80W AC to DC Switching PSU
, the brick is not what i suggested, but the brick is cheap, like $15.
As last remark, im not sure what you trying to do, is it for testing? i would think that the ISK 110 PSU is good enough, it rated 92% efficient, but this is a hobby for me, so if its like that for you then go for it. If you do try it, please share your results, specially idle and load consumption.
