Silverstone's new flagship PSU, the Zeus ZM1350, is based on a high performance platform that offers high power output at very high ambient temperatures, excellent ripple suppression, good voltage regulation, the ability to, for the enthusiast user, adjust the voltage of the three main rails, and, on top of that, merge the six +12V rails into a powerful single rail through the flip of a switch. Its fully modular design, the large number of available cables and connectors, and the high-quality finish complete the picture of Silverstone's new Zeus, and because nothing is perfect in this world, the ZM1350 has some weaknesses as well. For starters, it is equipped with a very noisy fan that struggles to move the heat out of the enclosure once the ambient exceeds 40°C. Even at lower loads, the fan profile is really aggressive, which makes the fan spin near its maximum speed most of the time. Moreover, the PSU's length is enormous, so there will most likely be compatibility issues with a lot of cases. Finally, efficiency at very low loads is disappointing, and the PSU is not ErP Lot 6 2010 compliant.

To sum up, and this is for sure, the new ZM1350 is not a PSU that addresses the average Joe or your average system. On the contrary, enthusiast users and, more specifically, hard-core overclockers will highly appreciate its features, especially the ultra-low ripple, its stable outputs, and the ability to easily adjust the voltages of the major rails. Its high operating-noise will probably be less of an issue to its specific target audience since such users are used to high-noise devices due to the number of noisy fans they already use to cool various components. None of them will even notice the ZM1350's low efficiency on benchmark-specific breaks. This PSU will meet the competition head-on if Silverstone manages to offer the unit for a price closer to the $300 mark.
