1000 W ATX 12V v2.31 Power Supply

This 1000 W unit follows the ATX 12V v2.31 standard and delivers power through a single +12 V rail. Full modular cabling lets builders connect only the leads they need. It targets high-end desktop systems that demand clean, reliable energy.

80 PLUS Gold Efficiency Limits

The 80 PLUS Gold badge guarantees 90 % efficiency at typical load across a 100-240 V, 50/60 Hz input range. Active PFC corrects power factor automatically. Hold-up time exceeds 16 ms and the power-good signal arrives within 100-150 ms.

Six PCIe And Eight SATA Connectors

Six 6+2-pin PCIe plugs feed multiple graphics cards while eight SATA connectors serve storage arrays. The compact 140 mm depth fits tight chassis. Protections cover over-voltage, over-power, short-circuit, under-voltage, over-current and over-temperature.

Questions about this item

Will this power supply fit in a case that only accepts units up to 140 mm deep?

Yes, the unit is exactly 140 mm long so it matches that limit.

Can I run a graphics card that needs two 8-pin PCIe connectors with the cables included?

The supply provides six 6+2-pin PCIe connectors, enough for multiple high-end cards.

Is the fan likely to stay quiet at low loads?

The 120 mm hydraulic bearing fan stops completely when the load is light, keeping noise to a minimum.
