What this power supply is

A 1000 W power supply, rated 80+ Gold, fully modular.

Efficiency
80+ Gold means about 90% of the power from the wall reaches your parts at half load; the rest becomes heat. Higher ratings run cooler and cost a little less to run.
Cables
Every cable unplugs, so you only fit the ones you need: the tidiest build.
New GPU connector
Has the 12V-2x6 (12VHPWR) cable, so newer RTX cards plug in directly without an adapter.
Rule of thumb
Pick a supply that runs at about half to two-thirds of its rating in games: quieter, cooler and room to upgrade.

Enough for
