- Full compliance with ATX 3.1 and PCIe 5.1 standards including a native 12V-2x6 high-power cable
- Short 140 mm (5.51 in) chassis depth ensures broad compatibility in space-restricted ATX enclosures
- High electrical conversion efficiency certified at 80 PLUS Gold (≥90% under typical loads)
- Ten-year manufacturer warranty supported by comprehensive UVP, OVP, OPP, OTP, and SCP protections
- Operating ambient temperature ceiling is rated at 40°C rather than the 50°C enthusiast standard
- Hold-up time threshold (≥16 ms) is validated at 80% continuous load rather than full 100% capacity
- Includes three legacy PCIe 6+2-pin cables, limiting multi-card setups that require four discrete 8-pin leads
Overview
Delivering 1000W of continuous power across modern ATX 12V 3.1 and PCIe 5.1 standards, this power platform integrates an Active PFC, LLC half-bridge, and DC-to-DC conversion topology designed for clean voltage regulation and steady transient excursion response. Power delivery to modern graphics accelerators is handled directly via a dedicated 12V-2×6 connector, eliminating the need for multi-plug breakout adapters and ensuring compliance with updated high-draw PCIe specifications.
The physical assembly is contained within a compact 5.51 x 5.91 x 3.39 in (140 x 150 x 86 mm) steel enclosure, preserving critical clearance inside compact mid-tower and small-footprint ATX cases. Internal thermal dissipation is driven by a 4.72 in (120 mm) cooling fan equipped with Fluid Dynamic Bearings (FDB), balancing bearing longevity and acoustic performance across its rated 32°F to 104°F (0°C to 40°C) operating window. The fully modular interface utilizes embossed flat black cables, facilitating clean bend radii and organized cable runs behind motherboard trays.
Circuit integrity is managed by five hardware protection mechanisms covering under-voltage, over-voltage, over-power, over-temperature, and short-circuit faults, coupled with a power-good signal latency timed between 100 and 150 ms. Certified for 80 PLUS Gold efficiency with typical conversion reaching at least 90%, the unit delivers a hold-up time of at least 16 ms at 80% load and carries a mean time between failures exceeding 100,000 hours at 25°C ambient, backed by a 10-year manufacturer warranty.
