The Enermax Revolution D.F. X 1650W is another great power supply from one of the best known names in the PC sector. This is an incredibly efficient unit which exceeds the 80 Plus Gold rated certification Enermax claim it achieves. We know that Aris' excellent Cybenetics platform have rated this power supply at Platinum efficiency levels.

We can't help but feel the RGB functionality is somewhat of a gimmick, although it is hard to fault Enermax for trying to appeal to a specific audience who enjoy lighting effects. Many users will hide the power supply at the bottom of a chassis anyway, but I do like how Enermax have opted to include a physical button to control the RGB, without the need for messy, resource-hogging software installs. You can also disable it with a button press, ignoring it completely if you wish.

Technically, the D.F. X 1650 is a capable power supply. Ripple suppression is a little higher than we would like to see when loads reach in excess of 1000 Watts, but the unit still falls within industry rated parameters. Load regulation is fairly good.

The efficiency of this unit and the adoption of multiple, fairly large heatsinks, ensures this PSU runs cool, even under heavy, extended loads. The large dual ball-bearing fan forces a lot of air through the unit, aiding stability, even in warmer conditions. The Enermax ‘DFR' (Dust Free Rotation) is an interesting concept as we detailed earlier in the review. We have no way to properly test it long term, but in theory it should remove some dust particles from surfaces.

It is always good to see when a company uses high grade Japanese capacitors in their designs, spending a little extra money to aid long term reliability. We have noted Enermax used 105C rated Rubycon capacitors in another  D.F. X unit we reviewed, but we found 105C rated Nichicon caps in this 1650W unit. Both these brands, along with Nippon Chemi Con, are market leaders.

Right now this power supply is not available for sale in the United Kingdom. Current availability is limited to certain parts of the world with Amazon in Europe listing it at around 350 euros HERE. We asked Enermax about UK stock arriving in the channel and they said it should be available in May over HERE, for around the £300 price point.

If you need a power supply capable of massive power delivery then the Enermax D.F. X 1650 deserves some serious consideration, if you can find it. It exceeds the modest 80 Plus Gold claims on the box, and is capable of delivering in excess of 1,800 Watts in our testing.

Pros:

• Exceeds the 80 Plus Gold claims – more like Platinum.
• Fan will counter spin to help remove dust.
• 105C rated Japanese capacitors from leading manufacturers.
• Delivered over 1,800 Watts.
• Physically small footprint is a huge plus point.
• RGB functionality.

Cons:

• Likely to be difficult to find.
• RGB functionality won't appeal to everyone.

KitGuru says: Enermax have been conservative rating this unit, it achieves Platinum levels of efficiency. It is quiet, powerful and adopts 105C rated high grade Japanese capacitors from Nichicon in the design. The software-free RGB support works well, and can also be disabled.
