FSP Group Dagger Pro 850W

A 850W unit with 80+ Gold efficiency certification and full cabling. It uses the SFX form factor — confirm your case lists SFX 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.

Expect to pay around $129.99, which lands it among high-end options. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and fold its price into your running build total. FSP backs the product through its standard warranty channels; check the listing for region-specific terms.
