SEASONIC Τροφοδοτικό 750W Modular (80+Platin)

The Seasonic FOCUS-SPX-750 is a compact, fully modular SFX power supply that delivers 750 W of continuous power in a small footprint (125 × 100 × 63.5 mm). Supplied with an SFX-to-ATX adapter bracket, it can be installed in both SFX and standard ATX chassis. The unit is 80 PLUS Platinum certified, offering high efficiency across typical loads, and uses Seasonic’s hybrid fan control alongside a Fluid Dynamic Bearing (FDB) fan to balance cooling and acoustic performance.

Advantages

The FOCUS-SPX-750 combines a super-compact SFX form factor with full modular cabling for flexible system builds and cleaner cable management. Its 80 PLUS Platinum efficiency reduces wasted heat and power draw. The patented three-stage hybrid fan control (fanless, silent, cooling) optimizes cooling according to load, while the 92 mm FDB fan reduces noise, friction and vibration for longer service life.

Suitable for

• Compact small-form-factor (SFF) gaming and workstation PCs
• Mini-ITX builds where space and airflow are limited
• Upgrades requiring high-efficiency, reliable 750 W power delivery
• Systems where low noise and long-term reliability are priorities

How to use

Install the FOCUS-SPX-750 into an SFX chassis or attach the included SFX-to-ATX adapter bracket to mount it in a standard ATX case. Connect the modular cables to the PSU and then to the motherboard, GPU (PCIe), storage (SATA) and other peripherals as required. Ensure correct orientation of the 20+4 pin ATX connector and secure all connections before powering on. Verify system stability under load and allow adequate case airflow when running at higher loads.

Recommendations

Allow the hybrid fan control to operate automatically; this provides fanless operation at low loads, silent cooling at moderate loads, and active cooling when the system demands higher thermal dissipation. Regularly check and clean case vents to maintain optimal efficiency and cooling performance.
