常问问题
The main difference is efficiency certification. FOCUS PX ATX 3.1 v5 carries 80 PLUS Platinum, while FOCUS GX ATX 3.1 v5 is 80 PLUS Gold. The PX range starts at 850 W and goes up to 1000 W, so GX also gives you a 750 W option if your system does not need as much power.
The dual-color design makes the connection easier to check visually when installing the graphics card cable. As with any 12V-2×6 connection, the connector should be fully inserted before the system is used, with no sharp bend immediately next to it.
It can be. Despite offering up to 1000 W, the PSU is only 140 mm long, which leaves more room for cables and other components than many larger ATX power supplies. Case dimensions should still be checked before installation.
OptiSilent combines Hybrid Mode with digital thermal control and PWM fan regulation. At low load the fan can remain off, while at higher temperature or power demand its speed is adjusted as needed for cooling.
That comes down to the complete system. An 850 W PSU is already enough for many powerful gaming PCs, while 1000 W gives more room for systems using higher-power components or future upgrades. If you are unsure, the Wattage Calculator can help you check the complete configuration.
