Questions about this item

Does the AP-MPS3ATX30 include all cables or must I buy extra SATA or Molex leads?

The unit ships with a 24-pin ATX, one 4-pin CPU, two SATA, three Molex, one floppy, one 6-pin auxiliary and one HP video connector.

Should I pick the 115 V or 230 V input setting for my region?

The supply accepts both 115 V and 230 V AC at 50/60 Hz, so it works worldwide without a separate version.

Will the 300 W rating actually run a modern mini-server with a PCIe graphics card?

The 300 W output and a 6-pin PCIe connector support current ATX 2.2 boards and an add-in GPU within that power envelope.
