So last month I released my first Power Supply Review.  Now with all these new miners showing up its time for an update.  Below is a list of what is most important when looking for a mining power supply and how I chose my top 5 mining power supplies:

  • 1kW (1000W) or greater capacity.
  • 80 PLUS Gold certification of efficiency or higher.
  • Quality fan (FDB or similar, ideally it should be DBB).
  • At least six 6 + 2 pin PCIe connectors, or eight 6 + 2 pin connectors on PSUs with more than 1.1kW capacity.
  • At least four 4-pin Molex connectors on more than two cables.
  • Supports essential protection functions (SCP, OPP), including over temperature protection.
  • Complete stage of EMI filtering together with input current protection.
  • Impeccable construction quality, which includes quality MOSFET and high-quality capacitors for filtering.
  • For 1.4 kW and stronger power supplies, a C19 coupler is required. An AC 14 AWG power cord should be used. For smaller capacity power supply units, an AC power cord of at least 16 AWG is required.

Top 5 Mining Power Supplies

  1. EVGA SuperNOVA 1600 T2

Price:  $299.99

Maximum Power:  1600W
Fans:   140mm Double Ball Bearing
Main Connector:  24Pin
+12V Rails:  Single
PCI-Express Connector:  9 x 8pin (6+2), 5 x 6pin
SATA Power Connector:  16

This thing is a monster.  It is hands down the best single PSU solution for any 6 card mining rig.  With adjusted voltages, it will easily run a six card setup of 1080TI’s of RX VEGA 64’s.  It also removes the hassle of running 2 PSU’s.  It is hard to find for a good price but this will be my UPS of choice for my upcoming RX VEGA 64 build.

This power supply easily takes the #2 spot.  Not only for its power rating and efficiency but for the price.  This will easily run 5 1080TI’s or RX Vega 64’s.  And 6+ of any other card.  This would actually be a great PSU if you wanted to build a cheaper mining rig with 8 1050TI’s or RX 560’s.

3.  Corsair HXi Series, HX1200i

Price: $249.99

Maximum Power:  1200W

SATA Power Connector:  12
SLI:  SLI Ready
CrossFire:  CrossFire Ready
Modular:  Full Modular
Efficiency:  92%
Energy-Efficient:  80 PLUS PLATINUM Certified
Over Voltage Protection:  Yes
Connectors:  1 x ATX Connector
2 x EPS Connector
2 x Floppy Connector
12 x 4-Pin Peripheral Connector
8 x PCIe Connector
12 x SATA Connector

Easily the best 1200W power supply on the market.  Will safely run 4 1080TI’s or RX VEGA 64’s (Can run 5 but not advised). And again will run 6 of most any other card.  The cool feature of this PSU is that you can use the Corsair link software and monitor all aspects of you UPS.

The best small PSU on the market.  This power supply is great if you want to start mining on a budget now, and add a second one later.  Alone it can run the same card amount as the 1000w above, there just isn’t any extra power room.  A second one will net you the power of the Super Nova 1600, but then you will have to deal with 2 power supply’s, extra plugs and extra cable management.  It basically stems down to how much room you have and how many rigs you are trying to run.

Conclusion

In summary,  picking the right power supply is just as important as picking the right graphics cards.  If you try to cheap out on a UPS, you can cause multiple problems including stability issues and undervolting your cards. You can also burn your power supply up or damage those brand new cards you bought. Remember you must also factor in all your other Rig parts.
