650W ATX 3.1 Power Supply

The SAMA HAT-650yzB1G is a 650W ATX 3.1 compatible power supply built for modern desktop systems. It delivers a single +12V rail rated at the full 650W and meets Cybenetics Gold efficiency standards. Fully modular cabling and a 140mm FDB fan keep the interior tidy and the acoustics low. Japanese capacitors provide stable power delivery across the load range.

Suits Compact Builds And Modern GPUs

This unit fits cases with a 150mm depth clearance and includes a 12V-2x6 connector for RTX 40 and 50 series graphics cards. The ECO fan mode stays silent under 40% load, making it a good match for quiet workstations or small form factor gaming rigs. Systems needing more than 650W or multiple PCIe power cables should consider the 750W, 850W or 1000W models in the same series.

Headroom For Single High-End GPU

At 650W the supply comfortably powers a CPU plus one high-end graphics card drawing up to 600W through the 16-pin connector. Two SATA power connectors and one 6+2-pin PCIe cable cover typical storage and peripheral needs. Efficiency stays above 90% at typical loads and hold-up time exceeds 12ms at full load. The design leaves no spare PCIe cables for a second power-hungry GPU.

Questions about this item

Will the 12VHPWR connector support an RTX 40 series card at full power?

Yes, the 16-pin 12V-2x6 connector is rated for up to 600 W and is compatible with RTX 40 and 50 series graphics cards.

Does the fully modular design include enough SATA connectors for three drives?

The unit ships with two SATA power connectors; a third drive would require an additional modular cable or adapter.

Can this 650 W unit fit in a compact case with a 150 mm depth limit?

The power supply is 150 mm deep, so it matches that exact clearance — verify your case specification before ordering.
