1000W ATX 3.1 power supply

The SAMA HAT-1000yzB2G delivers 1000W of continuous power through an ATX 3.1 compliant design. It targets high-performance gaming PCs and content creation workstations that demand stable, efficient energy delivery. Fully modular cabling keeps builds clean and airflow unobstructed. A 140mm FDB fan with ECO mode stays silent under light loads.

Upgrade from older ATX units

This unit replaces power supplies lacking the 12V-2x6 16pin connector required by modern RTX graphics cards. The jump is worth it when your GPU draws up to 600W through that single connector and you need Cybenetics Gold efficiency above 90%. Active PFC and a single +12V rail simplify the transition. Hold-up time exceeds 12ms at full load for ride-through protection.

Ideal for compact, quiet high-end builds

The 150mm depth fits most cases including small form factor chassis, suiting builders who prioritise low noise and Japanese capacitor reliability. It suits systems running RTX 40 or 50 series cards within the 1000W envelope. Users needing more than three 6+2-pin PCIe connectors or additional SATA power ports should look at something else.

Questions about this item

What case clearance is needed for the 150 mm deep PSU?

The unit is 150 mm deep so it fits most standard ATX cases including compact builds; measure from the rear panel to any drive cage or motherboard tray to confirm at least 150 mm of free space.

How do I connect the 12VHPWR 16 pin cable for an RTX 40 or 50 series card and what step is often missed?

Plug the supplied 12VHPWR 16 pin cable directly into the PSU’s native 12V-2x6 port and seat it fully until the latch clicks; the common mistake is leaving a 1 mm gap which can cause melting.

When should the 140 mm FDB fan be cleaned and how?

Clean the fan intake every 6 to 12 months with short bursts of compressed air while holding the blades still; the fluid-dynamic bearing is sealed and does not need lubrication.
