Questions about this item

Which cables come in the box and which ones must be purchased separately?

The unit includes a 600 mm 24-pin ATX cable, a 700 mm 4+4-pin CPU cable and an 8-pin CPU cable, all with nylon sleeving. Because the supply is fully modular, any additional PCIe or peripheral cables required for your build must be bought separately.

How do I decide between the available wattage options for this model?

This specific model is rated at 1200 W on the +12 V rail at 100 A, with 22 A each on the +3.3 V and +5 V rails. Choose it when your combined GPU and CPU draw approaches that ceiling; a lower-wattage unit would be a different SKU.

What does the 1200 W rating mean once the supply is installed in a system?

It means the +12 V rail can deliver up to 100 A continuously while the +3.3 V and +5 V rails each supply up to 22 A, all within the 80 PLUS Gold efficiency target and the ATX 3.1 / EPS 2.92 specifications.
