INTRODUCTION

   Even though modern ATX power supply units have been around for quite some time now the latest ATX 3.0 and PCIe 5.0 standards combined is arguably the most important update they've received in the last decade (if not more). Not only do these two standards allow for higher outputs and electrical efficiency, they also deliver cleaner and more stable energy to your hardware components thus making such units especially ideal for use with the latest (and upcoming) GeForce RTX and Radeon graphics cards. Up until even just 4-5 months ago there weren't really that many ATX 3.0 and PCIe 5.0 power supply units available in the market, today however they are and since we've had a steady stream of such models arrive in the lab lately today, I'll be taking a closer look at the upgraded Hydro G PRO 850W model by FSP.

   FSP Group is one of the global leading power supply manufacturers. Since its establishment in 1993, FSP Group has followed the management conception “service, profession, and innovation” to continuously fulfil its responsibilities as a green energy resolution supplier. With the combination of its leading role in power supply technology and the cultivation of green energy field, FSP Group now provides more competitive quality products and makes itself the most reliable partner for customers, consumers, and suppliers with joint creation of maximized values.

   As mentioned earlier the Hydro G PRO line first made its appearance roughly 5 years ago but FSP just upgraded that entire line to comply with the ATX 3.0 and PCIe 5.0 standards. So, the new Hydro G PRO line includes just two output models (850W/1000W) both of which are fully modular and are 80 Plus Gold efficiency certified (at least 90% electrical efficiency). The 850W output variant of the Hydro G PRO line which I’ll be testing today can deliver up to 850W of continuous power (986W peak - 1700W for up to 100ms, always according to the ATX 3.0 specs) and features a single strong +12V rail (70.83A) which can deliver the units entire power output (850W), active PFC, LLC half bridge topology, ECO semi-fanless mode (fan doesn't spin until 30% load), 100% Japanese capacitors, conformal interior coating for increased durability/endurance and several electrical protections including OVP (over-voltage), SCP (short-circuit), OPP (over-power), OCP (over-current) and OTP (over-temperature). As with past models FSP covers the entire Hydro G PRO line of ATX 3.0/PCIe 5.0 power supply units with a very generous 10-year limited warranty.
