Phanteks AMP GH 850W

This is a 850W unit with 80+ Gold efficiency certification and full cabling. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. It uses the ATX form factor — confirm your case lists ATX support. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Expect to pay around $119.99, which lands it among high-end options. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Phanteks backs the product through its standard warranty channels; check the listing for region-specific terms.
