ENERMAX Platimax 600W EPM600AWT
Fan is 600 RPM at idle and 1500RPM max not bad but definitely not 0 RPM at idle like some of the newer high efficiency PSUs. It is however a magnetic ball bearing design that should be reasonably quiet for a 140mm fan. PSU fan runs for 30-60 seconds after shut down to dissipate the remaining system heat and prolong system lifetime. 7 blade fan with struts facing the "wrong way" so it will have some noise from the 4 struts. I would have hoped for lower RPM fan on the 600W model.
What makes this special considering the fan isn't up to SPCR best?
Full modular cables PSU with 89-94% efficiency @20-100% load
. Compliant with 80 PLUS Platinum standard.
Also ErP Lot 6 2010 ready. Advanced +5Vsb circuitry with up to 20% improved efficiency in comparison with generic designs helps your system meet ErP Lot 6 2010 (AC < 1W at standby) requirement. (requires ErP lot 6 compliant motherboard to achieve this).
The 600W version is what I'd be interested in but the only review so far is for the 1200W version. http://www.hardocp.com/article/2011/09/ ... ply_review
Expect the 600W version to be between $150-$200 US. Good for a gamer/higher power home server but not necessarily better than getting a quieter 80Plus Gold unit from Seasonic, a Platinum from Kingwin/Superflower or other competitors. Really only worth looking into if you plan to run multiple video cards or if the price drops down the road.
