The FSP Hydro G 850W power supply is rated for a combined, continuous output power of up to 850 watts at 50°C operating temperature. The PSU incorporates a single +12V rail, which can deliver up to 70.8A (850W).  The PSU includes universal AC line input (automatically adjusts the AC line voltage) and active PFC (.95% to 1.00%), which makes the unit more environmentally friendly to the local power grid.

Modular ATX, CPU and PCI-E power cables

Notably missing was a second EPS 8-pin cable/connector. Granted not everyone needs this but at the 850W power level we would expect one to be included.

Why would you brand something "Hydro" when it has no provision for watercooling? We sadly haven't seen a WC-capable PSU for quite some time.

There hasnt been a need for watercooling PSU these days with higher efficiency components used.

For ATX monsters maybe, but if you want something more compact (e.g. SFX, FlexATX) where you are limited in maximum fan size by case dimensions, being able to offload cooling for the system to a central radiator is a huge benefit for noise and case volume.

maybe it's me, but using water as a name for a power supply just doesn't sound right.

I thought maybe it was a liquid cooled power supply. Just what I need in my system, more radiators and fans.

In fact FSP already has liquid cooled PSU and it is called HYYDRO PTM+

Just a note if anyone is reading this, I bought this PSU a week ago and it came with two 8 pin CPU connectors.Both on one cable, first one is 8 pin, second is 4+4. Around 15 cm between them.
