Direct plug no external brick correct?
Correct. Retail box contains just the hub, a USB cable, and a two prong wire for power.
the typical "brick" functionality is inside the hub/Superbpag.
there is no external "brick".
My 2c: don't run multiple sticks at above 200-250mhz. the table shows that 250 mhz is already exceeding superpag's 2A/slot.
before, i tried to run 5 Compacs on a superpag and when i overclocked, superbpag (box itself) was overheating.
If you want to overclock above 200, I would use Y-cables and only use 3 or less sticks/superbpag
