Cabling is fixed rather than modular, with the full set attached at the unit: a 20+4 pin motherboard connector, one 4+4 pin CPU lead, two 6+2 pin PCI-E connectors, four SATA and four Molex. That covers a single graphics card alongside a normal spread of drives and accessories. The casing measures 140 x 150 x 86 mm, the standard ATX footprint, so it drops into any compliant chassis.

The +12V rail carries up to 45.8A, which is where nearly all of the 550W total output reaches the processor and graphics card. The minor rails add 20A each on +3.3V and +5V, capped at 105W combined. Peak output is rated at 715W, active PFC holds a 0.99 power factor, and C6/C7 state support lets a modern platform drop into its deepest idle modes.
