Digifanless 550W
EDF550AWN
Fully modular

Product Introduction

The Digifanless 550 Watt is the first digital and fanless power supply from Enermax. Its powerful passive cooling system allows a completely silent operation with 0 dB(A). State-of-the-art technologies and long-lasting quality components ensure extremely stable and energy saving operation with up to 93% efficiency (80 PLUS Platinum). The power supply has a digital interface for reading and controlling central power values (e.g. voltage, efficiency or temperature) via the new ZDPMS software from Enermax. The fully modular cable management with the individually sleeved cables offers the greatest possible comfort during the system build.

Silent Operation. Brilliant Technology. Precious Design.

	Fanless Power Supply The sophisticated passive cooling system of the Digifanless power supply guarantees a completely silent operation (0db(A)). The PSU is therefore the first choice for all silent PCs, multimedia stations or HTPCs. Attention! Please keep the main air vent upside in the chassis. Do not block the air vents of the power supply and ensure an adequate air circulation in your PC system.
	Digital Monitoring & Control System The Digifanless is equipped with a digital interface to transmit and control the most essential performance values. With the ZDPMS software (“Zero-Delay Power Monitoring System”) users can easily monitor the power supply operation and customize certain functions, eg. switch between multi- or single-rail mode, fine tune the 12V output voltage or set the trigger points for OCP/OVP warning messages. More information about the various function of the ZDPMS software you can find in the >> ZDPMS manual. Please note that the software supports only Enermax power supplies with ZDPMS interface. >> Download ZDPMS Software
	Full-Modular Cable Management with Individually Sleeved Cables The full-modular cable management simplifies the system installation: Unnecessary cables can be detached to save space. The flexible cable sleeving allows for a comfortable and efficient cable routing. Enermax applies a high-quality black cable sleeving with individually sleeved wires, which creates a precious visual effect.

Efficiency

80 PLUS® Platinum
Up to 93% efficiency at 230VAC between 20 and 100% load. The Digifanless 550W is 80 PLUS® Platinum certified. The digital interface of the power supplies provides a continuous control of the system power consumption and efficiency rate. Thanks to the included ZDPMS software, users can further calculate the electricity costs and carbon footprint.
Support of EU Eco-Design Regulations
The Digifanless 550W helps systems to meet the EU eco-design directive ErP Lot 6 2013 (< 0.5W in standby mode*) due to a high-efficient 5V standby (+5Vsb) circuitry as well as the EU regulation no. 617/2013 demanding amongst others 85% efficiency at 50% load and 82% at 20% and 100% load.
* only in combination with an ErP Lot 6 2013 ready mainboard

Technology

DC-to-DC Design
The secondary voltages (5V & 3.3V) are generated by the primary 12V rail. This leads to a high-efficient operation, clean output voltages with an extremely low ripple noise as well as an optimal voltage regulation from zero to high loading.
Copper-Bridge Array
The innovative Copper-Bridge Array technology ensures a direct voltage transmission with low resistance and higher efficiency rates. Finally, the clean layout provides a more efficient air circulation and heat dissipation.
Multi-Rail Design with Single-Rail Option
Secure and stable power supply thanks to two high-performance and massive 12V rails with separate over-current protection (OCP). Possibility to switch to single-rail operation via the ZDPMS software to run PC systems with high performance or overclocked graphics cards and CPUs.

Safety & Quality

Durable & High-Quality Components
Enermax applies high-quality components incl. first-class Japanese 105°C electrolytic capacitors for maximum stability and durability.
24/7 @ 40°C
Non-stop industrial class performance at 40°C/104°F ambient. Continuous 550W power output with 605W peak power.
SafeGuard
The multiple protection circuit shields the power supply and the system from damage in case of short circuit (SCP), over voltage (OVP), under voltage (UVP), over current (OCP), over power (OPP), over temperature (OTP) as well as surges and inrush current (SIP). The ZDPMS software warns the user in case of increased current, voltages or temperature, so that precautionary measures can avoid the triggering of protections.
CordGuard
The convenient metal clip fixes the AC cord tightly and avoids accidental system crashes and data loss.
5 Years Manufacturer Warranty
