11 min read3 products evaluated
NVIDIA recommends 550W for the RTX 5060, and a unit at or slightly above that fits a budget build. Every pick is an ATX unit of 550W to 650W that cost $80 or less, ordered by wattage.
We sorted these picks by wattage, native 12V-2x6 cables and 80 Plus rating, working from the makers' own data; nothing here was tested in-house, and if a maker skips native 12V-2x6 cables, the guide says so.

Thermaltake Smart BM3 650W on Amazon (opens in a new tab)

The Thermaltake Smart BM3 650W has no stated native 12V-2x6 cable; confirm the cable kit before pairing it with a 16-pin card.
