Ready for modern graphics cards

The SAMA B750BK is a 750W ATX 3.1 power supply built for gaming PCs that need a 12V-2x6 connector rated at 450W. It carries Cybenetics Bronze and 80 PLUS Bronze certifications for verified efficiency. The non-modular design keeps cable management simple for standard builds.

Check your case and cables

This unit uses a fixed cable set including two 6+2 pin PCIe leads and six SATA connectors. Verify your chassis has room for a non-modular PSU and that your graphics card matches the supplied 12V-2x6 or 6+2 pin plugs. The single +12V rail and APFC + LLC + DC-DC topology deliver stable voltage under load.

Good fit for mainstream gaming rigs

It suits builders who want ATX 3.1 readiness and 450W on the new connector without paying for fully modular cables. If you need detachable cables for a compact case or custom sleeving, a modular unit would be a better choice.
