Seasonic SSR-550PX FOCUS 550W 80 PLUS Platinum ATX12V Power Supply

Full Modular 120mm FDB Fan Compact 140mm Size Power Supply 550W 80+ Platinum ATX12V & EPS12V from SEASONIC FOCUS Plus Platinum SSR-550PX

With many years of intensive active research and development, the engineers at SeaSonic have developed an entirely new product range.

FOCUS+ Series features outstanding electrical performance and a modern design resulting from this development.

There is no way you can resist a power supply this small and modular in this price range. You can choose from 80 PLUS® Platinum or Gold efficiency ratings.

80 PLUS® PLATINUM

80 PLUS® Platinum certification is achieved with SeaSonic Focus Plus Platinum 550W with 92 % efficiency at 50 % load.

CABLE-FREE CONNECTION DESIGN

The engineers at SeaSonic have used a new design element, where a copper plate connects the PCB (Printed Circuit Board) to the back panel rather than a cable.

As a result of this breakthrough solution, there are fewer production errors in manual insertion, and the quality of output is dramatically improved.

HYBRID SILENT FAN CONTROL

SeaSonic's patented advanced three-phase thermal control achieves the optimal balance between cooling and silence.

Silent Hybrid Fan Control operates in three ways: Fanless Mode, Silent Mode, and Cool Mode.

ADVANTAGES

• Noise reduction without temperature increase;
• A longer fan life due to fewer rotations of the fan;
• Constant heat dissipation;
• Fanless Mode offers the quietest performance available;

As a result of a switch on the back of SeaSonic's power supply, the Focus Platinum SSR-550PX 550W offers two fan control options: Fanless Control (fan control without fan-less operation) or Fan Control (fan control with fan-less function).

CONTROL BUTTON FOR THE FAN

A fan control button is located next to the power switch on the back of Focus PLUS power supplies, and you can choose from different fan control modes according to your needs.

The button should NOT be pressed if you choose the Fanless Mode, meaning that when the power supply is under light load, there will be no fan spinning on the power supply.

If you wish to have the fan spin all the time, even at low loads, press the button.

FAN BEARINGS WITH FLUID DYNAMICS

A Fluid Dynamic Bearing (FDB) fan is a high performance fan that takes advantage of oil's impact absorbance effect.

In comparison with ball bearing fans, they are extremely reliable and generate much less operating noise and heat.

By lubricating the bearing surface, friction and vibration are reduced and as a result, the power consumption is reduced.

This fan technology is also a great asset to prolonged fan life because it rotates more quietly and is robust.

A QUICK DESCRIPTION

During rotation of the fan shaft, high pressure oil drifts down the grooves of the bearing sleeve to make a thin layer of lubricant between the bearing faces.

Dynamic oil pressure increases as rotation speed increases, and the shaft is lifted from the bearing, resulting in smooth, effortless rotation.

In addition to channeling lubricant efficiently, the herringbone shape of the grooves prevents leakage.
