Etasis ET750 750w Quad-SLI PSU
As with all power supplies that pass through Overclock3D, I'll be taking a look inside the Silencer. By doing this I should be able to get a good idea of the overall build quality of the unit and how it is likely to perform in our tests.
Unlike traditional PSU's, the Etasis makes full use of the PSU casing, screwing full sized circuit boards on to both the top and bottom. This of course means they needed to fully protect the circuit boards from touching the casing, which has been done this by screwing large plastic sheets over the circuits.
Above we can see what appears to be an adjustable potentiometer (pot). This will most likely be responsible for adjusting the voltages on the rails of the unit and can be helpful when voltage levels fall outside of ATX specifications. Unfortunately I was unable to test whether this pot made any difference to the voltages, as the ET750 is far too awkward to disassemble and reassemble.
Cooling the Etasis is an 80mm fan manufactured by Sanyo Denki. The San Cooler 80
is able to push a total of 42cfm when running at 12v, with a noise output level of 34dBA.
