FOCUS SPX 2021)
The new line of Seasonic’s FOCUS SPX is versatile in its application and powerful with a small footprint. It is a standard SFX unit, measuring at 125 mm (L) x 100 mm (W) x 63.5 mm (H). The FOCUS SPX (2021) is shipped with an SFX to ATX adapter bracket in the box, which allows the power supply to be mounted not only in the SFX form factor chassis, but also a standard ATX chassis should the user prefers to reserve more space for airflow inside the PC case. The Seasonic hybrid fan control is always enabled to optimize the cooling according to necessity.

混合靜音風扇控制Fanless 約30%負載Fanless
業界首創、海韻 先進三階段熱控系統，實現靜音與散熱的完美平衡。此混合靜音風扇控制系統具備三種運作模式：Fanless 、靜音模式及強效散熱模式。
-
降低噪音而不增加溫度
-
由於風扇轉速降低，風扇使用壽命得以延長
-
隨時保持最佳散熱效能
-
Fanless 下無與倫比的靜音表現
流體動力風扇軸承
高性能流體動力軸承（FDB）風扇的設計充分利用了油膜吸收衝擊的優勢。此種風扇非常持久，同時也比雙滾珠軸承風扇製造更低的噪音和溫度。軸承表面的油膜幫助減少摩擦和震動，因此降低了總功耗。高效能且安靜的旋轉和堅固的結構大幅地增加了流體動力軸承風扇的壽命。
-
當風扇軸旋轉時，高壓油沿著軸承套筒的溝槽流動，在軸承表面之間形成薄層潤滑。
-
隨著速度提升，動態油壓隨之增加，軸心自軸承處抬起，從而實現平穩無阻的旋轉。人字形溝槽設計有助於高效導引潤滑油，有效防止滲漏。

常問問題
No. It is a standard SFX power supply, but Seasonic includes an SFX-to-ATX mounting bracket in the box. This means it can also be installed in a compatible ATX case if you want to use a smaller PSU or leave more.
Platinum refers to its efficiency under the 80 PLUS certification test conditions. High efficiency is particularly useful in a compact PSU because less input energy is wasted as heat inside a very small enclosure.
No. FOCUS SPX is a 2021 SFX platform and is not part of Seasonic's current ATX 3.1 lineup. If native 12V-2×6 or an ATX 3.1 PSU is required for your build, check the current ATX 3.1 product range instead.
No. On this model, the hybrid fan-control system is always enabled. The fan can remain off at lighter loads — Seasonic describes fanless operation up to approximately 30% load — and starts when additional cooling is required.
Choose according to the complete system rather than simply taking the larger model. Our Wattage Calculator can help you check the power requirements. Also keep in mind that the 750 W version has a different cable configuration, including two CPU cables, so check the connector requirements for your hardware before buying.
