SilverStone 1000W Platinum PSU, 140mm depth, fully modular, 120mm fan with magnetised filter

Silverstone Technology

SilverStone Technology ST1000-PTS-x 1000W 80 PLUS Platinum Power Supply

SKU CH-HWYS-SK00V

A 1000W 80 PLUS Platinum AT power supply with a 140mm depth, 100% modular cables, a single +12V rail, ±3% voltage regulation.

  • Product typeAT
  • 80 PLUS Platinum efficiency cuts wasted heat and electricity
  • 140 mm depth fits compact cases without sacrificing 1000 W output
  • 100 % modular cables simplify routing and improve airflow
  • Single +12 V rail with tight ±3 % regulation delivers stable power
  • Magnetised FF122 fan filter reduces dust and removes easily

Compact depth for tight builds

This 1000 watt power supply fits in a 140mm deep chassis, making it suitable for small form factor cases where longer units cannot be installed. It targets builders who need high output without sacrificing internal space. The AT type connector ensures compatibility with standard desktop motherboards. It is not for systems that require a larger physical footprint or non-standard form factors.

Magnetised filter and flat cables

The included FF122 magnetised fan filter attaches and removes without tools, helping to reduce dust buildup inside the unit. Fully modular cabling allows every lead to be disconnected, and the flat 24 pin cable folds tightly for cleaner routing. These accessories simplify assembly and ongoing maintenance. They do not add extra connectors or change the electrical specifications of the supply.

Platinum efficiency and single rail limits

The 80 PLUS Platinum rating means lower wasted heat and reduced electricity draw under typical loads. A single +12V rail delivers the full 1000 watts with ±3% voltage regulation and low ripple for stable operation up to 40°C ambient. The 120mm HYB fan balances airflow and noise. The unit cannot exceed its rated continuous output or operate beyond the stated temperature limit.

Questions about this item

What maintenance does the magnetized FF122 fan filter require over time?

The FF122 filter attaches magnetically for quick removal; clean it periodically with compressed air or a vacuum to maintain airflow and reduce dust buildup inside the unit.

What limits continuous 1000W output during sustained 24/7 operation?

The unit is rated for continuous 1000W delivery at up to 40°C ambient; prolonged loads above that temperature will trigger thermal protection before component limits are reached.

How does the HYB fan behave under all-day load regarding noise and heat?

The 120mm HYB fan runs quietly at low loads and ramps speed only as needed, keeping noise low while exhausting heat efficiently during extended 24/7 use.
