INTRODUCTION

   Even though I’ve never gone out of my way to avoid saying that compact PCs never really did it for me (the bigger the better) that’s clearly not the case with a somewhat large segment of the market today. Granted, enthusiasts, overclockers and gamers will probably also look at mid and full towers to house their new systems (which is why the market is primarily focused on full-size hardware components) but home and office users may see the benefit of a compact PC case. Quality components however are quite harder to come by and this is especially true for SFX power supply units. The brand new Dagger PRO line of SFX power supply units by FSP is a revamped version of their 2019 line and with me I have the 850W output model.

   FSP Group is the 5th largest power supply vendor in the world. Since the company was established in 1993, our outstanding management team has drawn together our R&D expertise, our sizeable production capacity, outstanding product quality to consistently excel in this competitive marketplace. FSP group is a publicly traded company listed in the Taiwan stock exchange, symbol: 30.15.TW, with revenues exceeding over 600 million USD. FSP group provides OEM/ODM power conversion products and services to the majority of well-established manufacturers and is the leading volume supplier of desktop PC ATX power supplies. In recent years, FSP group has expanded its R&D and manufacturing capabilities to become one of the major power conversion supplier of power adapters, industrial PCs, servers, LCD/LED monitors, LCD/LED TVs, heavy duty industrial products (UPS), portable battery chargers, Uninterrupted Power Supply as well as providing off-the-shelf consumer products, partnering with many strategic manufacturers.

   The new Dagger PRO line of PSUs by FSP is available in 550/650/750/850W outputs and features an 80 Plus Gold efficiency certification (up to over 90% electrical efficiency) and a very compact enclosure (125x100x63.5mm). The 850W model which i have here with me can deliver up to 988W (peak) and features a fully modular design (future-proof), strong 70.83A single +12V rail (can deliver 100% of the units total power output - 850W), minor rails with a total output of 138.6W, 100% Japanese capacitors, 4 PCIe 6+2 power connectors, SFX12V v3.3 compliance, semi-passive Zero RPM fan mode for inaudible operation at low loads and several industrial grade electrical protections including OPP (over-power), OVP (over-voltage), SCP (short-circuit), OCP (over-current) and OTP (over-temperature). Finally, FSP covers the entire Dagger Pro line with a rather generous 7-year limited warranty.
