1200W ATX power supply for high-end builds

This fully modular ATX unit delivers 1200W of continuous power with 80 PLUS Platinum efficiency. It targets enthusiasts building systems that draw heavy loads from multiple GPUs and overclocked CPUs. The compact 190mm depth fits most standard cases while leaving room for cable routing.

1200W capacity with Platinum headroom

The +12V rail supplies up to 100A, covering dual flagship graphics cards and high-core-count processors without saturation. At lighter loads the 0dB fan mode keeps the 135mm axial-tech fan completely stopped. Efficiency stays above 90% across typical loads, reducing waste heat. The unit runs out of headroom only when total system draw approaches the 1200W limit.

Fully modular cabling with Gen 5 connector

Included cables cover a 24-pin motherboard, two 4+4-pin CPU, eight 6+2-pin PCIe, one 16-pin PCIe Gen 5, twelve SATA and six peripheral plugs. Full modularity means only the needed cables occupy the case, improving airflow. An OLED panel shows real-time power draw and Aura Sync RGB integrates with compatible lighting ecosystems. Japanese capacitors and full protection circuits (OPP, OVP, UVP, SCP, OCP, OTP) back long-term reliability.

Questions about this item

Will the 190 mm length and 135 mm fan fit my older ATX case that has a 200 mm PSU bay?

The unit is 190 mm long with a single 135 mm fan, so it fits standard ATX bays that accept up to 200 mm depth.

How can I verify the OLED panel is reporting the +12V rail load correctly after first boot?

The OLED shows real-time power draw; compare its reading with software monitoring of the +12V@100A rail under load to confirm accuracy.

Which cables are included for the PCI-E Gen 5 16-pin connector and do I need extra SATA cables for six drives?

The box contains one PCI-E Gen 5 16-pin cable, four 1-to-1 and two 1-to-2 PCI-E cables, plus three SATA 1-to-4 cables giving twelve SATA plugs — enough for six drives.
