Mining PSU Round Up


Power Supply Unit Comparison and Review



A good mining rig needs a good PSU or two. Because the goal is to deliver steady 24/7 power to the rig, a really good PSU is something I don't cheap out on. Stick to the top PSU brands: reputable names like EVGA and Corsair.



So what do I look for? What is considered a recommended power supply? Right off the bat, brand reputation and warranty are supreme. A company that backs up their product with at the very least a 5-year warranty. Efficiency - Gold rated PSU or better (Gold - Platinum - Titanium). Also absolutely crucial is low voltage fluctuation (ripple) under full load and high temps. Also considerations: good fan, thick (min 18AWG) cables, standard protection features (Big 6: Over-Current-, Over/Under-Voltage-, Over-Power-, Short-Circuit-, and Over-Temperature Protections) and quality-tested signal-to-noise ratio and delay.

All that being said, could you get by with a cheaper off-brand PSU? Absolutely - but consider that the cheaper PSU's don't have many or most of the above efficiency and protection criteria.

The lists below may seem overwhelming (and it took me forever to put together), but it's easy to decipher. First determine the wattage you need, then determine the total number of connectors. Remember that a riser can be powered via either a 6-pin or a peripheral (molex) connector. If electricity is expensive (over $0.10/kW) then definitely opt for a Platinum or Titanium efficiency rating if available. Also remember that two or more PSU's may be used together in sync via an adapter cable.

KEY FACTS TO DECIPHERING THE TABLES:
Perif (molex) connectors should have no more than 2 connections per cable Number of VGA outputs Number of PCIe connectors
Even if a PSU supplies 2 rails of 4 perif connectors each (8 total), only 4 perif connectors are listed in the table VGA cables often have 2 chain-linked PCIe connectors attached.
Max watts across a single PCIe 8-pin connector: 150W It is perfectly acceptable to use cables with chain-linked (dual) PCIe connectors
Max watts across a single PCIe 6-pin connector: 75W GPU's must be powered by PCIe('s)
Max watts across a single Perif (4-pin molex) connector: 156W Risers can be powered by either PCIe (6-pin) or Perif (4-pin molex)
You cannot power a GPU or riser with a CPU 8-pin connector 6 pins of an 8-pin PCIe connector can be used to power a riser
