Power Up the Next Generation
Intel ATX 3.0 & PCIe Gen 5.0 Ready
Intel has published the new ATX 3.0 Specifications, totally changing the power supply game to take full advantage of next-gen hardware. ATX 3.0 PSU can support higher Power Excursion for NVIDIA RTX 4000 Series Graphic cards and 13th gen Intel CPUs.
More Stable, More Extraordinary
Supports 200% Power Excursion
Increased tolerance for high power spikes, for the compatible PSU platforms. For 450W PSU, up to 200% of the PSU's rated power for 100μs(microseconds) with a 10% duty cycle. For less than 450W, 150% PSU’s rated power could be delivered at maximum.

New 12VHPWR Power Connector
Previous Version
PCIe Gen 5
The PCIe Gen 5 (12+4) pin connector
- Rated current up to 9.2A per contact with all 12 power contacts.
- The 12VHPWR connector that uses 16AWG wires (600W) with fully isolated terminals.
- The PCIe Gen5 power connector is the new standard for PCIe add-in-card power. The standard allows you to power the graphics card with a single cable, which simplifies cable routing and improves airflow inside the chassis, among other benefits.
