I bought 2 Super Tornado 300s and one 350 from the Egg.
They don't actually have hardwired SATA power plugs, but a 4-pin molex-to-SATA power adapter is enclosed.
I got SATA drives in my system... But I'm using the 4-pin molex for them since the drives have both.
All my computers are now Seasonic-powered... And I can sleep at night even if I leave all three on-- They are that quiet.
HTH.
