Silencer ATX Power Supplies
There are three ATX power supplies available in the Silencer line: 310 watt, 360 watt, and 410 watt models. Not surprisingly, from the outside the only apparent difference between our 360 watt and 410 watt review samples is the name plate. But what I did find surprising was that on the inside they also appear almost identical. Upon closer inspection I noted the 410 had a few slightly larger components (heatsink, capacitor and fuse) and an extra capacitor that the 360 doesn’t have.
PC Power & Cooling also decided to eliminate the unused -5 VDC output, which has been removed from the ATX12V rev. 1.3 guidelines. (Some older ISA cards used -5 VDC.)

The Silencer 360 and 410 incorporate the same 80 mm rear mounted, variable speed, exhaust fan. The Nidec fan is rated for a maximum airflow of 34 CFM with a noise rating of 20-32 dBA. Under relatively light loads the fan is very quiet — virtually inaudible. As the PSU load (and internal temperatures) increases, the fan speeds up and can become quite noticeable.
The specifications for the higher capacity Silencer 410 ATX are almost identical to the 360 ATX except for the maximum current ratings on the +3.3V, +5V, and +12V outputs.

The Silencer 410 looks almost identical to the 360 except for a few slightly larger components and an additional capacitor. As mentioned above, the major difference between the 360 and 410 is the increased amperage capacity on the +3.3V, +5V and +12 VDC outputs. Here are some pictures of the Silencer 410 ATX power supply with the cover removed.

And finally, here are a couple pictures of the Silencer 360 ATX and 410 ATX side by side for comparison. As you can see, they are almost as hard to tell apart looking inside as they are from the outside. (Note the slightly larger heatsink inside the Silencer 410 ATX.)
