Performance (40% of the final score) - the CP-1000 does all the things the CP-850 did, only on a larger scale. It managed to do full rated power just fine, all while still keeping ripple and noise to wonderfully low levels. That said, I have to stop just a bit short of a perfect score this time, because the rail stability started to suffer on this model when confronted by my hot box. Still, 9.5 isn't too shabby.
Functionality (20% of the final score) - also like the CP-850, this unit fits perfectly into the cases for which it is designed. In this respect there's nothing I can fault... after all, you don't buy one of these for an ATX case with a PS2 sized power supply mount. What I do have to fault is the number of hardwired cables. This is getting annoying, Antec. Even a Twelve Hundred can be a cable hiding nightmare if you have enough of them you need to hide. So, I'm going to take off two points again - one for the number of hardwired cables, and one for not sleeving the hardwired cables into the case. 8.
Value (30% of the final score) - Neobits is currently selling these units for $150.95. Not a bad price for this kind of performance. But, you're only getting 6A more total 12V capacity on this unit when compared to the CP-850, which is a twenty dollar bill cheaper at the same place. So, while the CP-850 remains an excellent value for the performance one gets, I cannot say the same for big brother. 7.
Aesthetics (10% of the final score) - much like little brother, the CP-1000 is done up in that matte black color I like so much. But, I have to take a point off for the incomplete sleeving again. 9.
Antec's new form factor started off with a bang when we last saw it in the CP-850. That unit had literally everything going for it, and it remains one of the best power supplies I have ever tested. The CP-1000 wanted to be everything the 850W model was and more, but sadly it ended up being a lesser unit. Ripple and noise performance was exceptional, but the total 12V output only added up to 6A more capacity. This led to me having to max out the 3.3V/5V rails to meet full rated power, which in turn led to less stability on those rails. Another 10A of 12V capacity would have done wonders for this unit. As it stands right now the CP-1000 is another excellent product from Antec. But in the grand scheme of things it is only a small step up from little brother, and as such I can't quite toss out a recommendation this time.
ripple and noise suppression among the best units I've ever tested
extremely stable 12V regulation
quiet until you heat it up
gets noisy when severely stressed in a hot environment
3.3V/5V regulation could use some tuning up
only 6A more total 12V capacity than the CP-850
