Common questions about manuals, registration, and support for this brand.
You can use the 'paper clip method' or the included Power Supply Tester to jump-start the PSU. Disconnect all cables from your PC components, then connect the Green and Black pins (usually pins 4 and 5) on the 24-pin connector. If the fan spins, the PSU is likely functional.
Hybrid Mode allows the power supply fan to remain off during low loads to ensure silent operation. The fan only starts spinning when the unit reaches a certain temperature or load threshold.
No. You should only use the modular cables provided by Seasonic for your specific model. Pinouts can vary between brands and models, and using incompatible cables can damage your components.
In Hybrid Mode, Seasonic recommends mounting the PSU with the fan facing upward (if the case has ventilation) to allow heat to rise naturally. In Normal Mode, you can mount it facing down if your case has bottom ventilation holes.
