The unit's single biggest selling point is its \u003cstrong\u003e80 PLUS Platinum\u003c\/strong\u003e efficiency in a compact SFX chassis, which delivers stable power for high-performance small-form-factor systems while keeping heat and fan noise exceptionally low.

It is especially suitable for mini-ITX cases and SFX conversions where a full ATX unit is impractical. The strong single +12V rail and four 6+2 pin PCIe connectors make it a good match for mid- to high-range GPUs in tight spaces.\u003c\/p\u003e\n\n\u003cp\u003eIt is not for those who require an ATX drop-in replacement without an adapter, since an ATX adapter (sold separately as PP08) is required for ATX bays.
