1350w Enermax platinum series for my gaming PC (water cooled CPU and dual 290x's with over 10 fans).
1000w Enermax platinum series for my work PC.
Both of these were bought on special (shop's closing down sale) for about 1/2 price, both are of standard ATX sizes (I have even fitted the 1350w into a sff chassis at one stage), and the system only draws the power it needs - so why not.
And a 19v 65w for my NUC.
