Once upon a time, not too long ago, this very website took a look at a brand new offering from Silverstone, the OP1000. At one kilowatt, that unit was designed to take on the competition in the then recently introduced PC Power and Cooling Turbocool.
This article, written by our esteemed founder himself (now retired), pitted the two behemoths against each other. Back then, the OP1000 edged out the Turbocool by just a hair despite being a bit worse for ripple and noise.
