Product Overview 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

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.

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 latest 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 Features Compatibility

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.

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.

The convenient metal clip fixes the AC cord tightly and avoids accidental system crashes and data loss.

Date Issued: 4th Jul 2011

Let's face it, power-supply units (PSUs) are boring. Presented in what's usually a mundane box spitting cables from one end, this is a product that's neither aesthetically pleasing nor technically interesting to the majority of self-builders.

80 Plus certification
Date Issued: 18th Nov 2010

Conceived back in 2004 and brought to market just a year later, the 80 PLUS initiative is one of many standards introduced in an effort to increase energy efficiency in modern technology. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.9 or more at 100 per cent load.

550W Enermax Digifanless EDF550AWN, 93% Eff', 80 PLUS Platinum, SLI/CrossFire, Full Modular, EPS 12V, Fanless, ATX PSU is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from Looks great, shame it was dead on arrival I don't build computers for a living, but every once in a while I get asked too. The client said that reliability was a must, so I bought this for £180 to really secure reliability and keep it as quiet as can be. The product looks excellently made, the accessories are more than I could ask for, it really does look and feel like a quality component. The only disappointment is that it was completely dead on arrival (confirmed with PSU tester), providing no current to either the 24 / 8 pin motherboard connectors or SATA / PCI's. The additional disappointment was the time it took Scan not to respond to emails. After 4 days I did online chat, and magically I received the emails I should have got via my emails. Once they decided to act however, it was fast and doesn't effect me from making future purchases from Scan. I bought Scan ref LN47999 instead...fingers crossed.
