200 W ATX power supply

This 200 W ATX power supply delivers 80 PLUS Gold certified efficiency for compact desktop builds. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine.

Ideal for small-form-factor or low-power systems

Suits builders assembling Mini-ITX PCs, office workstations or embedded appliances that require quiet, efficient 200 W delivery. Zero RPM fan mode keeps the unit silent at low and medium loads. Not for configurations needing more than 200 W or auxiliary PCIe connectors for discrete graphics cards.

Fan behaviour and topology benefits

The Zero RPM fan mode switches the cooling fan off entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion reduces coil whine and enables more energy-efficient sleep states. No modular cables or additional accessories are mentioned in the specifications.

Questions about this item

Does the P4-250TS include the standard ATX 24-pin and CPU power connectors my motherboard requires?

Yes, as an ATX-type unit the P4-250TS provides the standard 24-pin main connector and CPU power connector needed for compatible motherboards.

Will the 200W capacity and Modern Standby support work with my older components that use traditional S3 sleep?

The 200W output and Modern Standby compatibility function normally with legacy hardware; the unit simply remains active in S3 states instead of entering the deeper Modern Standby sleep levels.

How can I confirm the Zero RPM fan mode is actually engaging during light loads?

Listen for fan noise at idle or low workloads — silence indicates the Zero RPM mode has stopped the fan, which resumes spinning only when internal temperatures rise under heavier load.
