VORTEX UMR Design Features

What makes the VORTEX Ultimate Mining Rig different?

To answer that let us define the two types of rig environments.

The first is the ‘open’ rig designs. What do we mean with ‘open’ design? It is simply that the rig is based upon an open non-enclosed frame, from wooden to plastic to aluminum and steel and all operational heat is vented into the immediate environment. What this means is, depending upon the immediate environment, the heat level will gradually rise unless acted upon by other forces. Those forces may be refrigerant A/C to cold locations (Iceland!). A variation of this is an exhaust system such as a hood that captures some of the heat and is subsequently vented outside. Here are photos of some ‘open’ mining rigs:

The Pros of this design are: Flexibility, lower cost, simple for beginners

The Cons are: No consistent power distribution design, no heat management

The other type is a ‘closed’ system. This is a rig that has the heat producing electronics located in an airtight enclosure with some insulation to keep the generated heat from leaking into the immediate environment. Of course, since the heat is separated from the immediate environment into that enclosure, it is important that this heat be quickly evacuated. This is accomplished with 4-6″ fans generating an airflow from 200CFM up. Additionally a combination of positive air influx and negative air exhaust can be used, especially if there are more than one rig. A pictorial of this arrangement looks like this:

In practice this means a closed system may be located in a living quarters and would add little additional A/C requirement to that area as the entry air would be drawn in from the outdoors and exhausted back to the outdoors.

The VORTEX UMR is a closed system design. Multiple rigs can be located in a spare room in a residence or placed in a ventilated external shelter. 

The VORTEX UMR is designed to use 1 or 2 HP or Dell 1200W Server switching supplies, mounted internal to the airflow plenum. The motherboard power is derived from a Pico PSU which, in turn is supplied by the main PSU 12V source. The unit has capacity for 8 full-size GPU cards mounted in a vertical orientation. The GPU power buses are divided 4GPU/4GPU with a separate PSU feeding each 4 card bus. The airflow connectors are a standard 4″ fitting compatible with many dust flow and HVAC systems. There are no standard PCIe power cables to worry with as the GPU auxiliary power is feed via copper buses with shorter connector tails that plug into the GPU cards. These cable tails are standard 6/8P Molex connectors. There is also a separate bus for the PCIe power connectors. The PCIe USB signal cables feed through the bottom panel of the rig straight into the MB PCI sockets. The following photos give a view of these features:

All control wiring comes into the module enclosure where you have a one switch on/off function (time delay relay powers on MOBO after power is present), digital displays of PSU1 and 2 voltages, CPU power and HDD LEDs and a pushbutton switch for starting the MOBO separately.

This presents a single glance presentation of the miner’s operational health.
