Questions about this item

Will the SFX form factor fit a standard ATX case with an adapter bracket?

The unit uses the standard SFX form factor and measures 100 mm in length. Many ATX cases accept SFX units when a separate adapter bracket is used.

Are there enough PCIe connectors for a graphics card that needs two 8-pin plugs?

The power supply includes four 6+2-pin PCIe connectors, so two 8-pin plugs are supported without adapters.

What does the 80 PLUS Platinum rating mean for daily power draw?

At typical loads the unit runs at 92 percent efficiency or higher, reducing waste heat and lowering electricity cost compared with lower-rated supplies.
