FSP kept the bundle fairly basic, with just a regular AC power cable, typical mounting screws, and a small manual to be found inside the box. The noteworthy addition to the bundle is the SFX to ATX adapter that allows the Dagger to be installed in ATX-compliant cases, allowing users the flexibility to switch between ATX and SFX cases at will. My favorite feature about it is the zero RPM fan mode that offers near-silent operation at low to medium loads. Pros:

Due to size restrictions, the designers were forced to use three APFC capacitors, the combined total capacitance of which is 420 uF. All three capacitors are supplied by Nippon Chemi-Con. There are two primary side inversion MOSFETs that form the heart of a half-bridge design, feeding a rather small unique transformer. You’re more likely going to need an ATX power supply. That’s unless the case manufacturer specifically states you use an SFX one. Modular DesignSince the new era GPUs require more power— especially the RTX 4000 series, an ATX 3.0 PSU ensures your build is future-proofed for power-hungry GPUs. Color ATX 3.0 is the new specification standard for PSUs. This new design adds a new PCIe 5.0 connector with 12 + 4 pins alongside the usual 6 or 8-pin connection.

But SFX PSUs come in smaller designs to fit in small form factor (SFF) cases because they don’t have the space needed to fit a full-size ATX PSU. The new connector is meant to make the power supply PCIe 5.0 ready. They have high power delivery for GPUs with up to 600W of power. Almost all PSU manufacturers design PSUs with the 80 Plus efficiency rating certification. The “80 Plus” rating system is the industry standard!

From the Manufacturer

Over the past decade, several ODMs decided to launch their own retail divisions. The most prominent examples are SeaSonic and FSP Group, whom release new retail products almost every time they upgrade their core designs. FSP Group recently performed a long-overdue update of their retail lineup and presented several fresh products. A few months ago we had a look at their top-end Hydro PTM Pro 1200W ATX PSU, an upgraded version of their tried & true flagship platform that has been around for nearly a decade. In today’s review, we are going to have a look at something significantly different – a very powerful 850W SFX unit, the Dagger Pro.
