Capacity & standard

The SAMA GT750-White is a 750 W ATX 3.1 power supply with full modular cabling and 80 PLUS Gold certification. It targets builders who need reliable power for modern GPUs such as the RTX 4090 and want a clean installation.

ATX 3.1 practical limits

The unit follows the ATX 3.1 and PCIe 5.1 specifications, providing a native 12V-2x6 connector that removes the need for adapters. Hold-up time exceeds 11 ms at full load and the input range covers 100-240 V at 50-60 Hz for worldwide use.

Upgrade path

Replacing an older ATX 2.x supply with this model adds the 12V-2x6 interface, Japanese capacitors and a fluid-dynamic-bearing fan rated for 100000 hours MTBF. The jump is worthwhile when moving to a PCIe 5.1 graphics card or when a fully modular, Gold-efficiency platform is required.
