Power Delivery for Modern GPUs

This ATX 3.1 unit provides 1200 W of continuous power through a single +12 V rail rated at 100 A. Two native PCIe 5.1 12V-2x6 connectors each deliver up to 600 W, satisfying the excursion demands of current graphics cards. The 80 Plus Gold rating certifies high efficiency across typical loads. Japanese main capacitors support long-term reliability.

Modular Cabling and Case Fit

Full modularity lets builders attach only the cables required, reducing clutter and improving airflow. The flat cable design eases routing behind motherboard trays and through tight grommets. A 160 mm chassis depth fits most standard ATX cases, while the 135 mm hydraulic bearing fan handles thermal load. Twelve SATA connectors and four peripheral plugs cover storage and accessory needs.

Sustained Load Behaviour

The single-rail topology distributes the full 1200 W without manual balancing, maintaining stable voltage during prolonged gaming or rendering sessions. Active PFC and a full protection suite (OCP, OVP, UVP, OPP, SCP, OTP) guard components against transients. The 135 mm fan speed scales with internal temperature, keeping acoustic output low at idle and providing sufficient airflow under continuous heavy draw. MTBF is rated at 100,000 hours minimum.

Questions about this item

How much continuous +12 V current can the 1200 W single-rail design deliver before hitting its limit?

The single +12 V rail is rated for 100 A continuous output, giving the full 1200 W capacity to the GPU and CPU combined.

What noise and thermal behaviour should I expect from the 135 mm hydraulic-bearing fan during all-day loads?

The 135 mm hydraulic-bearing fan runs quietly at low loads and ramps up only when internal temperatures rise, keeping the unit cool during sustained operation.

Which motherboard and GPU connectors must my build already provide for the native 12V-2x6 and EPS cables to work?

Your motherboard needs a 24-pin ATX socket plus an 8-pin or 4+4-pin EPS connector, and your GPU must accept the 12V-2x6 (12+4-pin) plug for direct attachment.
