ATX 3.1 power supply for modern builds
This 750 W unit meets the Intel ATX 3.1 specification and includes a native PCIe 5.1 12V-2X6 connector rated for up to 600 W. A 12 cm FDB fan and a 105°C main capacitor support continuous output at 40°C. The non-modular design uses etched flat cables for easier routing.
Suits single-GPU systems needing ATX 3.1 compliance
Builders who want a native 12V-2X6 cable without adapters will benefit from the direct connection. Systems that require fully modular cabling or a higher total wattage should consider other models. The compact 140 mm length fits most chassis, but very small cases may still be tight.
Verify case clearance and cable needs
Confirm the case accepts a 140 mm deep non-modular PSU and that fixed cables will reach all components. Check the motherboard requires an ATX 3.1 power-good signal of 100-150 msec and hold-up time above 17 msec at 80% load. Ensure the mains supply provides 100-240 V at 50/60 Hz.

Questions about this item
Will my graphics card work with the native PCIe 5.1 12V-2x6 connector that delivers up to 600W?
The unit includes a native PCIe 5.1 12V-2x6 cable rated for 600W, so any GPU using that connector will receive full power without an adapter.
Does the 140 mm length leave room for my existing drive cages and cable routing?
At 140 mm the housing fits most ATX cases, and the flat etched cables are more flexible than round ones, making routing around drive cages easier.
How can I confirm the matcha dual-coloured H++ connector is seated correctly after I plug it in?
The matcha colour disappears when the connector is fully inserted, giving a clear visual cue that the connection is secure.
