Measured by the lab, not the box · Cybenetics + PCPartPicker, synthesized in UltraDB

The 2026 Power Supplies breakdown.

Desktop ATX & SFX power supplies compared by what an independent lab actually measured — Cybenetics efficiency and noise, not the 80 PLUS sticker — then ranked by value. Every number traces to a Hardware Busters report or a live PCPartPicker price.

Start with the job — it drives every chart below

Price vs capability

Each bubble is a PSU; further right = more capable (wattage + measured efficiency + quietness + connector + warranty); color = product line. Re-scores when you pick a job.

What works with what

PSUs linked to the modern-GPU standards they support — ATX 3.1, native 12V-2x6 (the melt-resistant connector revision), PCIe 5.1, and the independent Cybenetics efficiency grade.

Compatibility — power supplies ↔ GPU standards

All power supplies

Method & honesty

Capability index — the formula (audit it)

Capability is the average of the five scored axes (wattage, measured efficiency, quietness, connector/standard, warranty); value = capability² ÷ price.

No single PSU wins every axis — the Titanium PRIME units top efficiency but cost the most and several are still ATX 3.0; the budget RMe units measure better than their Gold badge. Measured beats marketed.

Honesty. Accuracy is priority #1. Efficiency/noise are Cybenetics independent-MEASURED (exact % where the lab reported one, else the reported grade-band midpoint, flagged per card). Prices are live PCPartPicker US street prices where resolved, else the manufacturer/HWBusters MSRP (flagged); 2026 PSU pricing is volatile. A few premium units list MSRP only (no clean live price). Nothing is fabricated; unknowns stay blank.
