Strider Platinum 750 W power supply

The SilverStone Strider Platinum PS-ST75F-PT is a fully modular ATX unit rated at 750 W. It targets builders who want high efficiency in a compact 140 mm deep chassis. The 80 PLUS Platinum certification guarantees 89 to 92 percent efficiency across typical loads. A 120 mm fan stays off below 20 percent load for silent idle operation.

Single 12 V rail with 750 W capacity

The single +12 V rail delivers the full 750 W to graphics cards and CPUs without multi-rail balancing. Four 6+2 pin PCIe connectors support dual high-end GPUs, while eight SATA connectors handle storage arrays. Continuous output is rated for 40 °C ambient temperature, so headroom remains solid in warm cases. The unit accepts 90 to 264 V input at 47 to 63 Hz for worldwide use.

Fully modular cabling for clean builds

Every cable detaches, letting you install only the 24 pin, 8 pin EPS, PCIe and SATA leads the build requires. Included cables reach 550 mm for the motherboard, 750 mm for EPS and up to 600 mm for drives. Tight ±3 percent voltage regulation and low ripple protect sensitive components. MTBF exceeds 100,000 hours for long-term reliability.

Questions about this item

Will the 140 mm depth and 24-pin ATX connector fit my older case and motherboard?

The unit is 140 mm deep and uses a standard 24-pin ATX connector with a 550 mm cable, so it fits legacy ATX cases and motherboards.

How do I confirm the 80 PLUS Platinum efficiency and semi-fanless mode are active?

The 80 PLUS Platinum badge guarantees 89–92 % efficiency at 20–100 % load, and the 120 mm fan stays off below 20 % load for silent operation.

Which cables come attached and what must I add for extra drives?

All cables are fully modular; the box includes one 24-pin, one 8/4-pin EPS, four 6+2-pin PCIe and eight SATA connectors — buy additional modular cables only if you need more than those counts.
