8  Economy / Computer hardware / Gigampz: Power Supply Kits & Adapters For Bitcoin Mining. Industrial grade. on: May 23, 2014, 07:45:20 PM
Current Status in-stock

    Update: We are currently selling boards for HP DPS-800GBA, and HP DPS-1200FBA PSUs we also have designs for DPS-2000bb, and Dell Z750 PSUs available for custom orders.  Contact us for volume pricing and current discount deals.

    Update: We are now offering a 80Plus Platinum efficiency 1200 Watt power supply kit.  The absolute most efficient best value power supply for Bitcoin mining currently available.

    A number of you may have seen my prototypes of the Gigampz breakout board for the HP DPS-800GBA server power supply I've been working on.  I'm pleased to announce that they are now on sale and available for immediate shipping through our website  Bottom line is; this is the cheapest best quality plug and play power supply solution in terms of $/watt out there that doesn't require a lot of soldering drilling or other time consuming PSU modding.  You can have a 850+ Watt PSU for less than $70 compared to a typical ATX power supply that might cost $100 or more.

    These boards work with the HP DPS-800GBA server power supply the same supply used by the original ASICMiner backplane.  They can output 850 Watts (69.9 A @ 12.15V) on 120 V input or up to 1000 Watts (82.3 A @ 12.15v) on 240 V input.  The boards are built in the USA from high quality components designed to handle more current than the power supply is rated for.  The PCBs themselves have multiple heavy duty 2 oz copper power and ground planes and each of the 12 PWR/GND screw terminals is rated for 16 Amps.

    This supply paired with a Gigampz breakout board is capable of running 2 AntMiner S1's over clocked, 14+ Gridseeds, as well as other ASIC equipment requiring +12 Volt power.  Additionally these boards can be controlled and monitored either manually via a supplied jumper or via a Raspberry Pi, or Arduino.  The complete Gigampz DPS-800GBA spec sheet is available on the Gigampz FAQ Page
