Blackmagic Design Power Supply - ATEM Mini Extreme G2 120W

The Blackmagic Design Power Supply - ATEM Mini Extreme G2 120W (Manufacturer SKU: SUPPLY-12V120WLOCK) is an OEM replacement external power brick engineered specifically to match the dramatic power expansion of the Generation 2 (G2) ATEM Mini Extreme switcher family.

While original first-generation ATEM Mini Extreme units shipped with a smaller 60W adapter, the upgraded G2 hardware—which introduces massive internal processing upgrades including Thunderbolt storage recording links, 10G high-speed Ethernet, and phantom-powered XLR inputs—demands a much larger ceiling of power overhead to maintain thermal stability.

Critical Technical Specifications

Core Structural Features

• Threaded Screw-Locking Mechanical Collar: Live production environments cannot afford a loose or snagged cable killing a multi-camera broadcast. The DC output barrel features a physical, free-spinning knurled locking ring. Once slotted into the back of the ATEM chassis, you spin the ring to mechanically lock the power cord to the camera panel thread.

• Expanded Thermal Footprint: Because it continuously handles up to 10 Amps at full operational loads (such as when recording 8 channels of uncompressed ISO data directly onto external solid-state storage via Thunderbolt), the power brick is physically larger and insulated to safely dissipate heat over multi-hour production shoots.

Strict Backward Compatibility Cross-Check

⚠️ Over-Amperage vs. Voltage Safety: Because this brick regulates a strict 12V DC, it is technically safe to plug into smaller, legacy 12V ATEM switchers (like a standard 36W or 60W Extreme G1 unit). The device will only draw the amperage it requires. However, you should NEVER attempt to run a new ATEM Mini Extreme ISO G2 on an old 60W or 36W adapter—doing so will cause the older power supply to rapidly overheat, drop voltage under load, and cause the G2 switcher to randomly reboot or corrupt connected SSD drives midway through a live stream.
