Description
The SilverStone SX700-G represents a pinnacle of power density, packing 700W of 80 Plus Gold certified energy into a standard SFX chassis. Designed for enthusiasts who refuse to compromise on performance despite space limitations, this fully modular unit utilizes all Japanese electrolytic capacitors and a single +12V rail to provide rock-solid stability. Its ultra-flexible flat black cables simplify cable management in tight Mini-ITX cases, while the 92mm Fluid Dynamic Bearing (FDB) fan maintains a silent profile starting at just 18 dBA.
This product is for:
- SFF Enthusiasts: Builders creating high-performance Mini-ITX systems that require significant wattage for modern GPUs.
- Silent PC Builders: Users prioritizing low noise levels, benefiting from the 18 dBA minimum noise floor of the FDB fan.
- Professional Workstation Users: Those needing reliable, gold-rated efficiency for compact rendering or AI processing rigs.
- Cable Management Perfectionists: Builders who appreciate the 100% modular design and ultra-soft flat cables for a clean interior.
- Overclockers: Enthusiasts requiring strict ±3% voltage regulation and low ripple/noise for stable component tuning.

Installing the SX700-G is a seamless experience thanks to its 100% modular interface. The inclusion of dual EPS 8-pin connectors in the V1.1 revision ensures compatibility with high-end motherboards and power-hungry processors. During high-load gaming or productivity tasks, the active PFC and strict voltage regulation keep system crashes at bay. The flat cables are notably easier to route around tight corners than traditional sleeved cables, significantly improving airflow within small cases.
Compared to standard ATX power supplies, the SX700-G offers a massive reduction in volume without sacrificing the 700W overhead needed for high-end graphics cards. While many SFX units struggle with noise due to smaller 80mm fans, SilverStone’s integration of a 92mm FDB fan provides a superior acoustic profile compared to the SX650-G or entry-level SFX models. It bridges the gap between mid-range SFX units and extreme high-wattage variants, offering the best balance of size, power, and price.
Q&A:
- Is the SilverStone SX700-G compatible with ATX cases? Yes, it can be installed in ATX cases using an optional SFX-to-ATX bracket, though its short cables are optimized for SFF builds.
- Does this PSU support the latest NVIDIA and AMD graphics cards? Yes, with four 8/6-pin PCIe connectors and 700W capacity, it supports most high-end GPUs.
- What is the benefit of the V1.1 revision? The V1.1 update includes an additional EPS 8-pin connector, making it compatible with modern high-end motherboards requiring extra CPU power.
- How quiet is the fan during operation? The 92mm FDB fan starts at a near-silent 18 dBA and scales according to load, maintaining a low acoustic footprint.
- Are the cables flexible enough for tight spaces? Yes, the SX700-G uses ultra-soft flat cables specifically designed to bend easily in cramped Mini-ITX environments.
