Essential power for mainstream builds
The SilverStone Strider Essential SST-ST70F-ES230 delivers 700 W of continuous power from a single +12 V rail rated at 54 A. It carries 80 PLUS certification with 82–85 % efficiency across 20–100 % loading and active PFC above .9 at full load. A 120 mm fan runs at a minimum of 18 dBA for quiet home or office use.
Upgrade from lower-wattage or group-regulated units
This unit replaces older supplies that cannot sustain 700 W at 40 °C or that split the +12 V output across multiple rails. The jump is worth it when a graphics card demands an 8-pin and 6-pin PCIe connector pair and the system must run 24/7 without derating. Builders staying with entry-level GPUs or integrated graphics will not need this headroom.
Fits standard ATX cases with 180–264 V input
The 150 mm depth and 24-pin, EPS, four PCIe, four SATA and three peripheral connectors cover typical mid-tower layouts. Cables reach 500 mm for the motherboard and 750 mm for the CPU power plug. Over-voltage and short-circuit protection guard connected components. Systems requiring redundant supplies or server-grade voltage ranges are not addressed by this design.

Questions about this item
Will the 3.39 x 5.91 x 5.51 inch case fit in a standard ATX chassis?
The power supply measures 3.39 inches wide, 5.91 inches deep and 5.51 inches high, matching the standard ATX form factor used by most mid-tower and full-tower cases.
How do I connect the 8/4-pin EPS cable to my motherboard, and what is the common mistake?
Split the 8-pin block into two 4-pin halves if the board only has a 4-pin socket; the mistake is forcing the full 8-pin connector into a 4-pin header.
When should I expect to replace the 120mm fan rated for 100000 hours MTBF?
The fan is designed for 100000 hours of continuous operation at 40°C; in typical desktop use this translates to many years before a replacement is needed.
