Recently, @RinMP3, currently ranked #9 in the Season 2026 Rookie Ranking on HWBOT, shared an in-depth R&D evaluation of the Seasonic PRIME PX-1300 with us on an overclocked AMD Ryzen 7 5800X (PPT 124 W) paired with a GeForce RTX 5060.
While 270 W is only about 21% of the unit’s 1300 W rating, it is a useful real-world load for checking Hybrid Mode behavior, rail accuracy, and thermal rise — the conditions most systems actually live in day to day.
With Hybrid Mode enabled, the PRIME PX-1300 stayed… See More

fully passive (0 RPM / 0 dB) and held:
• +12 V — 12.160 V on a hardware DMM (+1.33% vs nominal; +0.53% vs OCCT telemetry)
• +5 V — 5.060 V
• +3.3 V — 3.330 V
• Exhaust ΔT — just 2.2 °C above ambient (30.3 °C exhaust / 28.1 °C intake)
No fan spin-up, no rail wander, and clean agreement between physical DMM and software telemetry under sustained load.
