The Best Power Supplies for RTX 5060 Ti
Five power supplies compared, from the darkFlash DG750 to the CORSAIR RM750e White, with the trade-offs of each named.
By The PC Journal editorial team
12 min read5 products evaluated
NVIDIA recommends a 600W power supply for the RTX 5060 Ti, so 650W to 750W leaves room for the rest of the build. Every pick is an ATX unit of 650W to 750W that cost $100 or less, ordered from the lowest price.
Our comparison rests on published figures for wattage, native 12V-2x6 cables and warranty; where a maker leaves out native 12V-2x6 cables, we say so, and no figure here comes from our own testing.

Best for
- Spending as little as possible, with the Thermaltake Smart BM3 650W the next step up.
Skip if
- Skip it if this is a deal-breaker for you: a shorter 5-year warranty.
Why we like it
Its warranty is 5 years. It is fully modular with a quiet HDB fan, 80 Plus Gold rated, and backed by a 5-year limited warranty. Its fully modular cables reduce clutter for first-time builders.
