Questions about this item

Will the 150 mm length and ATX 3.1 spec fit an older case that only has standard ATX mounting?

The unit is 150 mm long and built to ATX 3.1, so it uses the same mounting holes and 24-pin main connector as older ATX power supplies; verify your case clearance before installing.

How can I confirm the Matcha H++6 connectors are seated correctly after I plug in the two 12V-2x6 cables?

Each 12V-2x6 connector has a dual-coloured Matcha insert; when the green Matcha band disappears the connector is fully seated and locked.

Which cables come in the box and what must I purchase separately for a typical build?

The fully modular set includes flat cables for one 24-pin ATX, twelve SATA, four 4-pin peripheral and four 8-pin (6+2) PCIe; no extra cables are required for standard components.
