is listing them now with stock Oct 30. MSRP places them between the Seasonic G series and the Platinum X.
Gonna review one of these, jonny?
Jeremy already has one in his hands. Actually, I think there's a bunch of review samples out there, all of different wattages (except the 450W and 1000W because of delays at CWT), but there's a 9/23 embargo. On Monday, you should see a bunch of reviews pop up.
Among the ones made by CWT and made by Chicony (Hipro), which are supposed to be better on noise (assuming none of them have coil whine, then what are the coldest and efficient, in order that they do not begin to turn their fans too early and not using a high speed at full load)?
CWT vs. Chicony on component noise, the same. These aren't rebadged units and the components that were selected and used that were potential noise candidates are the same in both units despite the OEM. As for fan speed.. the 850W actually has the best fan speed profile. It's overkill for 99% of the people out there, but if the fan doesn't spin until 40% load (at 25°C ambient for an hour) and even then it only spins at 667 RPM (12.4 dbA measured) and stays there until 70% load, odds are that fan is never going to spin during average use.
The 450W and 550W have the same fan profile. 560 RPM (10.9 dbA) @ 40% load and it holds that until 80% when it jumps up to 726 RPM (14.3 dbA). Still pretty decent.
The 650W is probably the loudest at full loads. More than anything because it's taking that same CWT platform for the 450W and 550W and maximizing the maximum output wattage in the same cramped space. While the fan only spins at 560 RPM initially, it jumps up to 744, 888 and then a maximum of 1050 RPM (24.8 dbA
) when really pushed.
The other thing you want to remember about the fan speed is it's actually ramping up depending on temperature and time. Since that sort of thing is hard to communicate in simple graphs, they use % of load in the marketing collateral instead. But I've got PAL reports that show that most of the time, at 25°C, the fan doesn't even spin until the load is sustained for at least an hour. Obviously, higher ambient temperature will cause the fan to spin up sooner, but with so many cases allowing you to mount the PSU at the bottom, fan side down, you rarely have higher than room temperature PSU intake temps anymore.
