Compact kilowatt foundation

The ST1000-PTS is a 1000W fully modular ATX power supply built for systems that demand high output in a 140mm deep chassis. Its single +12V rail delivers 83A for stable distribution to modern components. The 80 PLUS Platinum rating confirms 89% to 92% efficiency across 20% to 100% load. Active PFC maintains a power factor above .9 at full load.

Silent operation at idle

A 120mm HYB fan with an intelligent controller keeps noise at 18dBA during low powered computing activities. The included FF122 magnetised fan filter helps reduce dust intake without tools. Full modular cabling means only the required leads are installed, improving airflow in compact builds. Input range spans 90V to 264V at 47Hz to 63Hz for worldwide compatibility.

Sustained load behaviour

The unit is rated for 24/7 continuous power output at 40 operating temperature. Protections include over power, over current, over voltage, under voltage, over temperature and short circuit safeguards. Voltage regulation stays within 3% with low ripple and noise under stress. MTBF is rated at 100000 hours for long term reliability.

Questions about this item

How do I install the ST1000-PTS and which step do builders often miss?

Mount the 140mm-deep unit in an ATX case, connect the 24Pin main cable and only the modular leads you need, then snap the FF122 magnetized fan filter onto the 120mm intake before first power-on.

What maintenance or replacement will the ST1000-PTS need later?

Clean the FF122 magnetized filter periodically; the HYB fan is rated for 100000 hours MTBF at 40°C continuous operation.

What limit appears first on the ST1000-PTS during sustained full load?

The single +12V rail caps at 83A, so total 12V draw cannot exceed that value even though the unit is rated for 1000W.
