Strider Platinum 650W ATX Power Supply

The SilverStone Strider Platinum is a 650W ATX power supply built for compact, high-efficiency desktop builds. It carries 80 PLUS Platinum certification and delivers continuous output at up to 40°C operating temperature. The fully modular cable design keeps internal wiring minimal and tidy.

Single +12V rail with Platinum headroom

A class-leading single +12V rail provides the full 650W to graphics cards and CPUs without multi-rail balancing. Voltage regulation stays within a strict 3% window and ripple is kept low. The fan remains off below 20% load, giving silent operation during idle or light workloads.

140mm depth fits small-form-factor cases

At 140mm deep the unit slides into space-constrained chassis while still offering a 120mm semi-fanless cooler. Modular PCIe cables support multi-GPU configurations without cable clutter. Builders needing higher peak wattage or non-modular cabling should look elsewhere.

Questions about this item

Will the 140 mm depth fit in an older case that only has room for a standard ATX supply?

The unit is 140 mm deep, which is shorter than many traditional ATX power supplies, so it should fit in most cases designed for standard ATX dimensions.

How can I confirm the 120 mm fan is running in semi-fanless mode when the system is idle?

Below 20 % load the fan stays off completely; you can verify silent operation by listening for zero fan noise during light desktop use.

Which cables come pre-attached and which must be connected from the modular set?

No cables are permanently attached; the 100 % modular design means every cable — including the 24-pin ATX, CPU and PCI-E leads — is supplied loose in the box for you to plug in as needed.
