Product information

Description

Pure Power 12 M 1200W is an ATX 3.0 compliant, PCIe 5.0 compatible power supply designed for reliable operation with modern and next-generation graphics cards. The unit includes both a dedicated PCIe 5.0 cable and additional PCIe 6+2 pin cables to ensure broad compatibility across current GPU models and upcoming releases. Engineered to deliver steady power with low noise, this PSU targets users who need high-capacity, standards-compliant power delivery.

Advantages

Pure Power 12 M 1200W combines ATX 3.0 compliance with PCIe 5.0 support and multiple PCIe 6+2 cables, providing extensive compatibility and future-proofing for new graphics cards. The design emphasizes quiet operation and dependable performance under load, while the included PCIe 5.0 cable ensures direct support for GPUs requiring the new connector standard.

Key specifications

Form factor: ATX 3.0 compliant
PCIe compatibility: PCIe 5.0 compatible

How to use

Install the PSU in a compatible ATX case following the motherboard and case manufacturer instructions.
