Swedish company Fractal Design has today introduced a new range of semi-modular PSUs to its product catalogue, the Edison M series.
The range starts at 450W and is available in 100W increments up to 750W. This makes them suitable for any single GPU system as well as a number of dual GPU systems (particularly the 650W and 750W ones). They are all 80 PLUS Gold rated too. This means that on a standard 230V power supply their efficiency is at least 90 percent at 20 percent load, 92 percent at half load and 89 percent at full load.
Fractal Design also promises that electrical performance elsewhere will be excellent. It says that voltages on the 12V rail will never vary beyond 2 percent of the nominal value, while on the less used rails (3.3V and 5V) they will always be within 3 percent. It also says that ripple on the 12V rail will be less than 50mV, which is certainly very low. The Intel ATX specification dictates that voltage variation cannot be more than 5 percent and that ripple on the 12V rail must be lower than 120mV, so Fractal is well within the limits. In fact, the Edison M PSUs are fully compliant with the ATX 2.4 and EPS 2.92 standards, with full support for the C6 and C7 power states introduced with Intel's Haswell processors.
Reliability is also said to be high. The PSUs are built using Japanese electrolytic capacitors, as well as Japanese and Taiwanese solid polymer capacitors. The PSUs are protected against over temperature, over voltage, under voltage, over current and short circuits too. The temperature-controlled 120mm fan uses fluid dynamic bearings for a longer lifespan, and every Edison M PSU ships with a five year warranty.
The PSUs are black, while the 120mm fan is white – a classic Fractal look. All four capacities are 160mm deep.
The Edison M power supplies utilise a single 12V rail design. In ascending order of wattage, they are rated to supply up to 37A, 45A, 54A and 62A on this rail.
As mentioned, the new units are semi-modular, meaning some cables are fixed to the power supply while the rest are modular. The captive cables, which are braided, include the 20+4 pin motherboard and 4+4 pin CPU ones, as well as a single cable with two 6+2 pin PCI-E plugs on the 650W and 750W models. The 4+4 pin ATX12V cable is a whopping 70cm, regardless of wattage, so even very big cases shouldn't need an extension cable for it to reach.
Meanwhile, the modular cables are flat and black, and the number you receive varies from model to model. The 450W comes with just two 6+2 pin PCI-E connectors while the rest have four. All four capacities have five Molex plugs and at least six SATA plugs, though this increases to ten in the top tier 750W model, which also has an additional 8-pin EPS12V cable for motherboards with dual CPU power plug.
UK MSRPs stand at £62.99 (450W), £69.99 (550W), £77.99 (650W) and £89.99 (750W). More information can be found on the official product page.
