Fonte de alimentação Silverstone SX700-PT 700 W

The Silverstone SX700-PT is a compact SFX power supply unit delivering 700 W with 80 PLUS Platinum efficiency. Designed for small form factor PCs, it features a powerful single +12V rail, all-Japanese electrolytic capacitors and a built-in 92 mm FDB fan for effective cooling with low noise. The unit uses a fully modular cable design and flexible flat cables for simpler routing and cleaner builds. Typical connectors include a 20+4 pin ATX motherboard connector and SATA power leads in varied lengths. The PSU supports an AC input range of 90–264 V at 47–63 Hz and is finished in black.

Advantages

The SX700-PT offers a high-efficiency 80 PLUS Platinum rating and ±3% voltage regulation with low ripple and noise for stable system operation. A single +12V rail provides ample headroom for high-end component upgrades or moderate overclocking. Use of all Japanese electrolytic capacitors and a fluid-dynamic bearing 92 mm fan improves longevity and quiet operation. The 100% modular flat cables simplify cable management and allow for tighter folding in compact cases.

Suitable for

• Small form factor (SFX) gaming or workstation builds
• Compact home or office PCs requiring quiet operation
• Systems that may receive high-end GPU or CPU upgrades
• Enthusiast builds where tidy cable management is important

How to use

Install the SX700-PT into a compatible SFX or SFX-L chassis following the case and motherboard manufacturer instructions. Connect the 20+4 pin ATX cable to the motherboard, then attach required PCIe, SATA and peripheral cables from the modular panel to the components. Route the flexible flat cables and secure them to maintain airflow and reduce clutter. Verify input voltage compatibility and connect the AC power cord to a grounded outlet before powering on.

Recommendations

For optimal performance, ensure adequate case airflow and avoid obstructing the 92 mm fan. Use only the supplied modular cables or Silverstone-approved replacements. Check power requirements of future upgrades to ensure the single +12V 700 W capacity meets system demands.
