Description
Power your overclock with confidence. The Bitaxe 40W 5V 8A power supply delivers a true, regulated 5.0 volts at up to 8 amps, giving single-chip miners 33 percent more current headroom than a standard 6 amp brick. It ships with the correct 5.5×2.1mm center-positive barrel jack and interchangeable heads for North America, the EU, the UK, and Australia. Same-day shipping from Houston, Texas.
Skip the guesswork of generic 8 amp adapters. Many third-party units use a loose-fitting 5.5×2.5mm plug that causes power dropouts under load. This supply is matched to the Bitaxe standard and certified for safe continuous operation.
