Zalman ZM300A-APF 300W Switching Power Supply ReviewBosco -
The voltages were too unstable for me to take an accurate screenshot on full load, so I ended up capturing the results only when the computer is idle. I used Motherboard Monitor to take these readings.
In terms of accuracy, I'd say that the voltages are pretty accurate, with the exception of the +12V line. By the same token, my Enermax readings of that line is also lower than the rest of the other readings... it may have something to do with my current configuration, but I can't say for sure. I've shared all of my cables evenly to prevent any particular rail from becoming overloaded. It could be the CPU itself, which in turn may be an indicator for me to pickup a 350W power supply, or even a 400W or 450W, to be on the safe side.
In terms of noise, the quietness is incredible! I purposely turned off all my case fans, leaving only the fans on my video card, CPU, and the power supply itself, and the system is pretty much mute. Only if I deliberately concentrate on the noise will I hear it then. Overall I am quite pleased with the results.
Once again Zalman comes out with another solution to the never-ending noise! While the unit has only one fan, it's incredibly quiet, and it gets the job done nicely. The Active PFC is a good addition to any power supply, but it's really difficult to justify paying more than $80CAD for only 300W, Active PFC or not. I like the multi-connector as well, because if my fans were originally 3-pin, I don't need to introduce additional cabling for the converters, and I can save up on using the 4-pin peripheral plugs at the same time.
