1000W ATX 3.1 Power Supply

The SAMA HAT-1000yzB2G is a 1000W ATX 3.1 power supply from the G-Series range. It targets builders of high-performance gaming PCs and content-creation workstations who need reliable, efficient power delivery. The fully modular design allows users to connect only the cables required for a clean internal layout. A 140mm FDB fan with ECO mode keeps operation quiet under light loads.

Single 12V Rail with 12V-2x6 Connector

The unit uses a single +12V rail rated for the full 1000W output and includes a native 12V-2x6 connector capable of delivering 600W to modern graphics cards. Cybenetics Gold certification confirms efficiency above 90% across typical loads. Hold-up time exceeds 12 ms at full load, and 100% Japanese capacitors support stable voltage regulation. Active PFC operates across a 100-240V input range.

Suits RTX 40 and 50 Series Builds

This supply suits compact and silent builds thanks to a 150mm chassis depth and a fan that stops below 40% load. It provides three 6+2-pin PCIe connectors alongside the 12V-2x6 port, two SATA connectors and a 24-pin main cable. Builders needing more SATA drives or additional PCIe cables for multi-GPU setups should look at a unit with higher peripheral counts.

Questions about this item

Will the 12VHPWR 16-pin cable reach a large RTX 40 or 50 series card in a full-tower case?

The fully modular design lets you route the native 12VHPWR cable directly from the PSU to the GPU without adapters, keeping the path short and tidy.

Does the unit fit in a compact case that only accepts 150 mm deep power supplies?

Yes, the chassis is 150 mm long, so it fits most small-form-factor and standard ATX cases that limit PSU depth to that dimension.

How loud is the fan during typical gaming loads?

The 140 mm FDB fan stays silent under 40 % load thanks to ECO mode, and runs quietly at higher loads due to the fluid-dynamic bearing.
