R9 380 Crossfire with 650w?

Solution


The 8370 was a worst-case scenario haha. The i5 2400 is much more efficient than that...


Depends on your CPU. I assumed you wanted another oven for your house, so I selected an AMD FX 8370 heater.

The BeQuiet calculator (not my fav, but it's ok) recommends a max wattage of 513W. This shouldn't go up or down with other components. CPU and Graphics Cards are the main power consumers.

It should be fine, although it's nice to have at least 100W headroom. Enjoy your heater/oven/greenhouse.
 


Well no. I have a I5 2400. Besides, i know the 8370 is equal to that.
