Antec NeoECO Platinum 850W

This is a 850W unit with 80+ Platinum efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

At $109.99 it sits in the mid-range power supply bracket. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Support and warranty service run through Antec, with terms that vary by region.
