There are a total of eight cable sets, as well as three fan-only connectors. All the cables are twisted on each other to reduce EMI interference. As an added bonus, this is quite helpful for cable management as it keeps the individual wires in a single bunch while allowing them to remain flexible as a group.

  • 22" sleeved cable for main 20/24-pin ATX connector
  • 2 x 23" 4-pin 12V auxiliary connectors
  • 2 x 18" EMI-shielded 4-pin Molex connectors
  • 2 x 35" cable with three 4-pin Molex connectors and one floppy drive power connector
  • 23" cable with two SATA power connectors
  • 3 x 27" Fan-only connectors wired to the fan controller in the PSU

Like several other power supplies we have recently reviewed, the Raidmax uses a separate 4-pin connector that clips onto the side of the 20-pin connector to form a full 24-pin plug for use with the newest motherboards.

A similar system is used to join the two 12V auxiliary connectors that are included. The two auxiliary connectors clip together to form the 8-pin connector that is standard for dual-CPU systems.

Two 12V auxiliary cables are included for use with dual-CPU boards. They clip together for convenience.

Two of the standard 4-pin Molex connectors are heavily EMI shielded with copper mesh and Topower's REMIC technology. Raidmax intends these to be used for a VGA card, but most modern cards (i.e. the ones that require external power) now comply with the PCI-Express standard that requires a different connector. There are a few cards that use older chipsets that use the Molex connector, but these are quite rare. However, there is no reason why these cables cannot be used to power a hard disk.

Maxpower includes two special Molex connectors with extra EMI shielding.

The Raidmax also features three fan-only connectors similar to the one found on the PSU in Antec's Sonata case. These are wired to the internal fan controller, and feed a variable voltage depending on the internal PSU temperature. Some fans will require an inexpensive adaptor to fit the standard Molex plug that these connectors use.

The fan-only connectors are all powered from the fan controller PCB inside the PSU.
