Description



This item is brand-new, factory sealed.

Compact Power, Limitless Performance

The Toughpower SFX Platinum series is built to support next-gen hardware, meeting the latest Intel SFX 12V 4.1 and ATX 12V 3.1 standards. With its native PCIe 12V-2x6 (12+4pin) modular interface, it efficiently powers PCIe 12+4pin graphics cards. This series not only achieves 80 PLUS Platinum efficiency but also guarantees stability, durability, and reliability.

No Matter the Case Size, We've Got You Covered

The dimensions of the Toughpower SFX Platinum measure 125mm(W) x 63.5mm(H) x 103.8mm(D).

It comes with an SFX to ATX adapter bracket as an accessory which gives users more options when choosing the ideal case for the build.

Fully Compatible with ATX 3.1 Standards

Toughpower SFX Platinum series is fully compatible with ATX 3.1 Specifications which supports up to 200% power excursion, reaches 60% low load efficiency and complies with required power supply timing standards.

PCIe Gen 5.1 Ready

Toughpower SFX Platinum series comes with a PCIe 12V-2x6 connector to offer powerful and stable performance allowing the PSU to natively run next-generation GPUs.

The wattage marked on the PCIe 12+4-pin cable connector represents the recommended wattage (Ref. Intel design guideline). The bundled PCIe Gen 5.1 (12+4pin) cable connector of the Toughpower SFX Platinum 1000W can deliver up to 600W for PCIe 12+4pin graphics cards.

Made to Comply with the Latest Graphics Cards

Ready to supply graphics cards according to their different ways of connections, the Toughpower SFX Platinum series is designed to support NVIDIA and AMD graphics cards, it supports 8-pin slots for AMD graphics cards & some RTX 40 series graphics cards, it also comes with 1 x 12V-2x6 connector for RTX 40 series cards with a PCIe 12+4pin connector.

  • 1 x 8-pin GPU Power Connector
  • 2 x 8-pin GPU Power Connector
  • 3 x 8-pin GPU Power Connector
  • 1 x 12V-2x6 pin GPU Power Connector

Be Smart, Stay Quiet

Equipped with a 90mm fluid bearing fan for superior airflow. Plus, the built-in Smart Zero Fan feature keeps it silent until the load hits 30%, reducing unwanted noise.

80 PLUS® Platinum Certified

80 PLUS Platinum certification means the Toughpower SFX Platinum series converts power efficiently, saves energy through its high efficiency up to 92%, resulting in lower power loss and heat buildup inside the power supply.

?30mV Low Ripple Noise Design

Top-end build quality with low ripple noise. All ripples are lower than 30mV on +12V, +5V or +3.3V from 0% to 100% load to ensure a stable operation and keep your performance-critical components to function reliably for longer.

Extremely Strict Voltage Regulation ?±2%

The voltage regulation is more strict than Intel's standard +5%,-7% for major rails and ±10% for -12V, is set to no more than ±2% for major rails, providing steady clean power through exceptional voltage stability.

17ms and up Hold Up Time

During a power interruption, your computer might shut down or reboot. We make sure that the SFX Platinum series will deliver at least 17ms at 80% workload, without system reboot or resetting.

More Stable than Ever

100% high quality Japanese 105°C/221°F electrolytic capacitors provides great durability as well as offering the highest stability, while remaining reliable.
