ATX 3.1 750 W Fully Modular PSU

The SAMA GP750 is a fully modular ATX 3.1 power supply rated at 750 W. It targets builders assembling modern gaming PCs or high-performance workstations. The unit includes a PCIe 5.1 ready 12V-2x6 connector for current graphics cards. Its modular design lets users connect only the cables their build requires.

Capacity and headroom

The single +12 V rail delivers 62.4 A for 748.8 W of combined output, covering most single-GPU configurations with margin. The 12V-2x6 connector is rated for 450 W, supporting high-end GPUs under heavy load. Efficiency exceeds 90 % at typical 50 % load, lowering waste heat. Protection circuits guard against over-voltage and overload conditions.

12V-2x6 connector decides fit

The defining specification is the 12V-2x6 (12+4) pin connector capable of 450 W delivery. This determines whether the PSU matches a graphics card that requires the PCIe 5.1 power interface. Systems using older 6+2 pin GPUs will use the two supplied (6+2) pin cables instead. Six SATA power connectors handle storage and peripherals.

Questions about this item

Will the 12V-2x6 connector work with my existing 8-pin GPU cables?

The 12V-2x6 connector is native for PCIe 5.1 cards; use the included 6+2 pin cables for older GPUs instead of adapting the new connector.

How can I confirm the unit is delivering stable power after installation?

Check that the 120mm FDB fan spins at low RPM under idle and that system voltages in BIOS or monitoring software stay within ATX limits on the single +12V rail.

Which cables come pre-attached and which must be added from the box?

No cables are pre-attached; the fully modular set includes one 20+4 pin, two 6+2 pin PCIe, one 12+4 pin, and six SATA connectors.
