Somebody over at Antec woke up one day and came to this realization: in looking at the backs of our cases at that power supply mount, we're dealing with a form factor over twenty years old now. While it has served us well over the years, power supplies have gotten bigger and bigger, to the point some of us are now stuffing 1600W units into that little opening. Antec figured they had a better idea: why not enlarge the PSU housing so there was not only more room for the guts, but less restrictions to hinder cooling? The result of this brainwave is the unit I'm looking at today, the CP-850. This is the very first product in Antec's new CPX form factor, and they're really hoping it catches on.
Now, before I get started on the review proper, I just want to clue you in on one important detail: there are only three Antec cases right now that will take a CPX power supply. Those cases are the Twelve Hundred, the P183, and the P193. Any other case will need modding, assuming there's enough space.
Only downside i see is size, and that only is meant for 3 cases, but i do own a 1200, so i considering buying one. And even if the fan isnt as quiet as the review makes it to be, im guessing it could be easly changed with SFlex or even a slipstream since its mounted vertically.I couldn't even hear that 120mm fan, that's how dull the hot box phase was. Looks like Antec's vision of a more efficient cooling system works.
CP-850 can outperform a Signature unit for ripple and noise suppression!!!
Just looking for more input, before i buy it, would appricaite any comments if anyone owns or have seen one in action.
