The Prime Ultra Platinum series of power supplies is primarily designed to build powerful and reliable gaming PCs. Specifically, this modification, first of all, can boast of having an 80 PLUS PLATINUM certificate and a rated power of 550 watts. The power supply received a full set of protective systems (OVP / UVP, SCP, OTP, OPP, OCP), which allows the device to power expensive computer hardware, which is extremely sensitive to power quality. It can also have a hybrid cooling system, and the fan is based on a high-quality hydrodynamic bearing, and therefore the Sea Sonic Prime Ultra Platinum SSR-550PD2 power supply is not prone to creating high noise. The wiring uses a fully modular connection concept. The list of interfaces includes the following connectors: motherboard power (20+4 pins),...CPU power (4+4 pins), additional graphics card power (several 6+2 pins), SATA (6 pcs), PATA (5 pcs), Floppy . The wires are protected by a high quality nylon braid. At the same time, the wiring is long enough for concealed installation via cable management. This power supply model has an ATX form factor and is designed for installation in a Mini, Midi or Full Tower system unit. High reliability, good protection and a good level of power make it possible to use the device when creating an advanced gaming system.

Efficiency 92%

Sea Sonic is one of the few companies that always offers users the most advanced power supplies. It was she who more than a decade ago was one of the first companies to release a power supply with an efficiency above 80%. Since then, it has been strongly associated with enthusiast products — high-quality, reliable, advanced and always quiet even under maximum loads. And the new series of Prime Ultra Platinum power supplies does not change these principles at all.

Modern circuitry

The combination of advanced circuitry and high-quality components using well-known Japanese capacitors has resulted in exemplary output performance. So, voltage deviations are much lower than the norms required by the ATX12V standard, and when the load changes, very high stability is observed on the three main power lines. You can't help but admire the attention to detail. For example, the unit comes with a handy case for storing detachable cables and several ties that make it easier to route cables inside the system unit.

Amazing attention to detail

The hybrid cooling system is also pleasantly surprising, which allows users to decide for themselves how to control the fan: be active all the time or switch to a semi-passive mode, turning off at light load. In both cases, it practically does not make noise: during the tests, the sound level metre did not rise above 18 dB. Despite such a low propeller speed, the heating of the internal components was very negligible. This made it possible to achieve impressive results when operating in overload mode — there is a power margin of 31%. Well, do not forget about the whole 12-year warranty. All things considered, the $160 price tag for a 550-watt model doesn't seem that high anymore.
