So there is half price this sunday on 3870K

I was going for the a6 3500, but now the a8 3870K is the same price, only this sunday.

I have orderd the origen ae m10, which comes with a 150W PSU.

Now the tdp on the 3870K is 100W, now, that leaves me 50W for RAM, MB and SSD

Should be fine, the TDP in the A8 is of course for CPU+GPU and SSD as well as DDR3 SDRAM is both in the "maximum a few watts" range. Motherboard I don't know, but for sure not whatever is left in the budget.
