Cable reach
The number of connectors provided is only one part of a power supply's cabling equation. How far those connectors reach is also important, especially if you're running a larger tower enclosure or one of those exotic upside-down cases that puts the PSU below the motherboard. Even if you have a relatively small, traditional case, longer cables can provide more routing flexibility.

With the help of our trusty measuring tape, we've determined the maximum cable reach for each PSU. The measurements shown for SATA and four-pin peripheral connectors refer to the reach of the last connector on the longest cable.

The Corsair VX450's primary power connector is a few inches longer than the competition and should easily accommodate monster tower enclosures. You also get plenty of primary power reach from Tagan and a decent stretch from OCZ, Enermax, and FSP. However, at barely more than a foot in length, the primary power cables on the Antec and SolyTech units will definitely limit your enclosure options. We had a rough time installing both in our mid-tower test system.

Auxiliary 12V reach is also a problem for the Antec and SolyTech units. The field doesn't get shuffled at all here, although the ModXStream and MODU82+ do pull away from the Blue Storm by a couple of inches.

Obviously, two of our contenders don't have any PCIe reach at all. Corsair continues to offer the longest cable reach here, followed closely by Tagan. Two inches separate the Enermax from the OCZ—and, in turn, the OCZ from the FSP.

Although FSP gives its Blue Storm a ridiculously long SATA line, the reach of its 4-pin Molex connectors is much shorter. The Corsair VX450W offers the longest cables on the Molex front, and it has plenty of SATA reach, too. Most of the pack provides plenty of SATA and 4-pin peripheral reach, but the Basiq's miserly 13" SATA cable is a notable exception. The Antec and SolyTech units also deliver the shortest Molex cables. In this case, you get what you pay for, I guess.
