SAMA White 750W Power Supply - Fully Modular 80 Plus Gold

Our review of the SAMA White 750W Power Supply finds it best suited for PC builders who prioritize clean cable management and reliable power for high-end GPUs. The single biggest reason to buy is its combination of a fully modular layout with native PCIe 5.1 compatibility, which makes it a straightforward choice for systems using RTX 30 or 40 series cards while keeping the interior neat and improving airflow.

Key Features

• Fully Modular Design: Allows connecting only the cables required by the build, simplifying installation and reducing clutter for better airflow.
• PCIe 5.1 Compatibility: Native PCIe 5.1 ports and cables ensure proper support for modern GPUs like the RTX 3090 Ti and RTX 40 series without adapters.
• 80 PLUS Gold Efficiency: Dual Gold certification delivers high efficiency, lowering wasted energy and heat, with up to about 91.15% efficiency near typical loads.
• Quiet ECO Fan: A 120mm fan with fluid dynamic bearing runs quietly, keeping noise low even under heavier loads.
• Premium Internal Components: Japanese capacitors are used to improve long-term stability and help protect sensitive components under sustained use.

Who It's For

This unit is aimed at gamers and workstation builders who need a reliable 750W supply that is ready for current high-end GPUs and who want tidy cable routing during assembly. The native PCIe 5.1 support makes it a practical choice for upgrading systems built around RTX 30 or RTX 40 series cards.

Users who require extremely compact SFX power supplies or who need a large bundle of legacy cables may want to consider other models; a few customers noted mixed impressions about included cable counts, so builders expecting a dense accessory pack should verify what is in the box.

Pros & Cons
