Hi, SPCR's testing suggests the Zalman 1000w maintains low noise to the highest power levels of any PSU tested so far. See table on last page for comparison of noise vs power for various PSUs. I believe the 850w version is the same internally and should have very similar acoustics, while the 750w a...

hx620 is modular, the s12+ isn't, you should be able to chase up extra pcie cables off corsair for it to, so you don't need use molex-pcie adapters to run SLI 8800gtx (which needs 4 pcie connectors, s12+ has 2). Otherwise mentioned m12 700w has 4 pcie connectors.

This states that they both have three rails and we don't need to be concerned about one getting overloaded as another will be used automatically. a bit of corporate smoke and mirrors there :).

99% is at load, under idle conditions say < 100w its often 'only' 95%. Keep in mind at < 100w its a only a watt or two extra. Same as claimed efficiency, its always at load (say 50-75% or something). some are worse dropping as low as 80%, eg.

I guess the original Adda is a 1600 rpm fan but in the lower bay there is no mobo (CPU, GPU) heat to take care of so it should be OK to swap for a 1200 rpm fan (Such as S-Flex D) instead. Noise should be lowered considerably then right? A s-flex may work well because its a fluid dynamic bearing fan...

Also current trend is 120mm fans on the bottom - sleave bearings run noisier and at a much reduce life when mounted horizontally - ie like in a psu. Hence adda ball bearings being the popular quiet choice, though be interesting to see how 'hydrowave' or other more exotic bearings go.

Something like an antec noisekiller may help, but imo it wont make a difference as the fans going so low speed its generating little vibration. Its more higher speed fans and hard drives that generate enough vibrations to make a big difference, though correct me anyone on this.

The way the m12 does it is both fans get fed the same voltage/fan controller. The only thing that makes the rear fan not startup is it has a higher startup voltage. This is why its 'rockin' a bit (its got a bit of voltage but not enough to get it spinning), and why if you actually managed get a high...

No not really, if your worried get an athlonxp motherboard which has a 'P4' 4pin connector, that way the cpu will power off the 12V rail instead. Still as long as its within ATX spec which it is i don't see any reason to worry.
