Product identity

The YEYIAN Pegasus 1000W is a fully modular ATX 12V power supply rated at 1000 W. It carries 80 PLUS Platinum certification with 92 % typical efficiency and meets ErP 2013 requirements. A native 12+4 pin PCIe 5.0 connector and Intel ATX 3.0 readiness target modern high-power graphics cards such as the 4080 and 4090.

Target build

This unit suits enthusiasts assembling systems that demand 1000 W of clean power with low ripple below 30 mV and tight voltage regulation. Builders who need only modest wattage or who cannot accommodate a 140 mm deep PSU should consider a lower-capacity or shorter model instead.

Deciding spec

The single specification that decides fit is the 1000 W maximum output combined with the native PCIe 5.0 12+4 pin connector; if your GPU requires that connector at this wattage the Pegasus matches, otherwise a different capacity or connector layout is required.
