FSP Dagger Pro 850W Report

Continuing the discussion from the introduction of my Antec P10 Flux review, what made John Wick 3 such a success? It is an interesting question to ask given that it is the third film in a very simple action series. All three John Wick films have the same elements -- high octane action with impressive fight choreography and an interesting world set up by the writers. What makes the films still interesting is the expansion of the world, especially with the third film. John Wick takes place in a universe where assassins have their own community to blend in with regular society, and the writers made the smart choice to really explore that in the third film, keeping the premise fresh with all the signature action the films are now known for. Despite being the third film in the series, John Wick 3 managed to add new elements to the story and characters while using the same action that hooked fans to the series in the first place. Today, we have the FSP Dagger Pro 850W, which is our third review of the FSP Dagger line with the first being the FSP Dagger 600W and the second being the FSP Dagger Pro 650W. Does the 850W version add some new elements to keep things fresh while maintaining all the best qualities of the versions that came before it? Let us read on to find out!

Our review unit of the FSP Dagger Pro 850W arrived via UPS Standard from their offices in Chino, California, USA. The shipping package arrived here in Calgary, Alberta, Canada. Other than a few minor dents, the medium-sized brown corrugated cardboard box arrived in good condition.

The retail packaging for the FSP Dagger Pro 850W is almost exactly the same as the 650W version. On the front, you will see a scaled-down image of the power supply unit on the center. The bottom contains an 80 Plus Gold efficiency sticker and some other stickers describing special features with this power supply unit. The power capacity is also labeled at the bottom of the box on the right side. Directly above are stickers that indicate it is IEC 62368 approved, 10 years of warranty, and Intel compatibility for the latest Intel CPUs. Other details, such as the given cables and power distribution chart, can be found around the box.
