1000 W Fully Modular ATX Supply

The Corn Electronics GW800 delivers 1000 W through an ATX12V and EPS12V design. Full modular cabling lets builders connect only the leads they need. Eighty Plus Gold certification confirms better than ninety percent efficiency at typical loads. It suits high-end desktop systems that demand clean, reliable power.

140 mm Ball-Bearing Fan and Active PFC

A single 140 mm ball-bearing fan moves large air volume while staying quiet in normal operation. Active power factor correction and an LLC resonant plus DC-to-DC topology keep input current stable across 100 to 240 V mains. Japanese electrolytic capacitors support the rated output at up to forty degrees Celsius ambient. Protections include OVP, UVP, OCP, OPP, OTP and SCP.

Compact 175 mm Depth with Rich Connector Set

The unit measures 175 mm deep, fitting standard ATX bays without clearance issues. Six 6+2-pin PCIe leads feed multiple graphics cards, while seven SATA and three peripheral connectors handle drives and accessories. A 20+4-pin main and a 4+4-pin EPS connector cover modern motherboards. Full Japanese capacitors and a hundred thousand hour MTBF underline long-term durability.

Questions about this item

How do I install the fully modular GW800 and which cable routing mistake should I avoid?

Mount the 175 mm long unit in the case, connect only the cables your build needs, and route the 24-pin ATX and 8-pin EPS cables behind the motherboard tray so they do not block the 140 mm fan intake.

What maintenance or replacement will the GW800 need after extended use?

The 140 mm ball-bearing fan is the only moving part; clean dust from its blades and the ventilation grilles periodically, and expect the unit to reach its rated 100,000 hour MTBF before any internal component requires replacement.

What limit appears first when the GW800 runs at full load for long periods?

The internal temperature will hit the 40 °C maximum operating limit before the 1000 W output or any protection circuit becomes the restricting factor.
