Building a PC at the moment is hard but if you are looking to put together a gaming rig or workstation and want a power supply will be powerful and reliable , the Seasonic Focus GX 850W ATX 3.1 is a strong contender for sure, and it is currently at its lowest ever price of just $125 (purchase link under the specs table down below).
Sitting in the middle of Seasonic’s refreshed Focus lineup, it delivers enough wattage for high-performance single GPU builds like with AMD"s RX 9070 XT or Nvidia"s RTX 5080. That means it natively supports the new 12V-2×6 connector required by some of these graphics cards, so you won’t need adapters or workarounds. The single +12 Volt rail on it outputs 70 amperes for 840 watts in total maximum continuous power output.
It’s also fully modular which makes cable management straightforward and helps airflow inside your case. Speaking of which, Seasonic has introduced its OptiSink cooling design here, a reworked internal layout that says it improves heat dissipation and airflow.
