Seasonic PRIME SSR-1600TR2 Power Supply Noctua Edition Review
Efficiency
At an 80 Plus Titanium rating, and from such a trusted manufacturer as Seasonic, I was expecting nothing but excellence from this PSU, and it certainly delivers. The efficiency graph looks damn near a straight line, which is quite rare. Often, we see more of a drop off at lower loads and higher loads, with a bit of a sweet spot around 60-80% load, but largely, this PSU hits around 95% efficiency and largely stays there.
PFC (Power Factor Correction)
The quality of the components, and the platform design being as modern as it is, the PFC is near perfect, with very little correction; there’s even less power wasted, less heat generated, and this can all result in both cleaner power delivery and a cooler, quieter power supply as a result.
Voltage Regulation
Anything under 3% is typically regarded as acceptable and very good when it comes to voltage regulation, being within a good average of the target voltage, with no particularly hot or cold rails at any particular load. However, this PSU is incredibly tight on tolerances, and that really shows here; the 12v in particular is as good as I’ve seen. Admittedly, many PSUs on the market have improved in this area in the last few years, but that doesn’t detract from how good this result is.
