Frequently Asked Questions about Seasonic
Answers for purchasing and planning
| What does 80 PLUS Titanium mean and what difference does it make in operation? 80 PLUS Titanium is the highest efficiency certificate of the 80 PLUS organisation. It requires at least 90% efficiency at 10% load and at least 92% at 50% load. Compared to a standard PSU with 80% efficiency, a Titanium PSU saves around 60 W of power dissipation in a 500 W workstation in continuous operation – equivalent to over 500 kWh less electricity consumption per year and significantly less heat output in the server room or office. |
| Which Seasonic PSU is suitable for professional workstations with high-performance GPUs? For workstations with powerful professional GPUs (NVIDIA RTX 4000/5000, AMD Radeon Pro), the Seasonic VERTEX series with ATX 3.0 compliance and native PCIe 5.0 connector is recommended. The VERTEX GX/PX models (750 W–1,200 W) are designed for the load peaks of modern GPUs and prevent unwanted shutdowns during brief overload transients. |
| Are Seasonic PSUs suitable for use in industrial systems and continuous operation? Seasonic PSUs are designed for continuous operation under full load – unlike consumer PSUs measured under ideal laboratory conditions. The Prime series is specified for operation at 50 °C ambient temperature under rated load. For 24/7 industrial computers and server applications, the Prime TI/PX series with 12-year warranty is the appropriate choice. |
