FSP Hydro K Pro 850W 80 PLUS Bronze ATX 3.0 PSU

What this power supply is

An 850 W power supply, rated 80+ Bronze.

Efficiency

80+ Bronze means about 85% 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.

New GPU connector

Shops don't list a 12V-2x6 cable; newer RTX cards then use the adapter in their box.

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

The fastest graphics cards in stock that this supply can run, with a normal processor:

• RTX 5080 needs 850 W+ from R 38 499 →
• RTX 4080 needs 800 W+ from R 30 189 →
• RTX 5070 Ti needs 750 W+ from R 27 243 →
• RX 9070 XT needs 750 W+ from R 21 999 →
• RX 9070 needs 650 W+ from R 23 334 →

With a top processor (Core i9, Ryzen 9) add about 100 W.
