BFG MX Series 550W PSU

Cables and Connectors

Affixed cables include:

• One 55cm 24-pin ATX cable
  
• One 4+4-pin EPS12V power cable

Modular cables include:

• One 55cm 6-pin PCI-Express cable
  
• One 55cm 6+2-pin PCI-Express cable
  
• One 55cm molex cable with connectors at 55cm and 70cm
  
• One 55cm molex cable with connectors at 55cm, 70cm and a floppy power connector at 85cm
  
• One 55cm molex cable with connectors at 55cm, 70cm, 85cm with a floppy power connector at 100cm
  
• Two 55cm SATA cable with connectors at 55cm and 70cm
  
• One 55cm SATA cable with connectors at 55cm, 70cm, 85cm and 100cm

BFG's braiding is notably thicker than many others - especially for the thinner cables for Molex and SATA cables, but they are tied off with zip ties that make it look a little ugly. When combined with the large open gap between ATX and EPS12V plugs and braid, we can't help but feel it looks a little amateurish.

The variety of cables is nice - the pair of dual socketed SATA cables and the third featuring four SATA connectors - although everything is a single length of 55cm away, and the inter-connector gap is a larger than average 15cm too. We think two floppy connectors are a little wasteful, but at least there's the right proportion of PCI-Express, CPU EPS12V, Molex and SATA included for most PCs.


The PCI-Express plugs are a cool shade of blue, and the 6-pin and 6+2-pin cover single high end GPU, or mid-range multi-GPU solutions. The +2 cable uses a thicker cable than others although, if we're pedantic, it's also a little excessive in length. Compared to the ATX and EPS12V cables, the braid on the Molex and SATA goes right to the plugs, but there are no 90 degree SATA options or plastic quick release plugs on the Molexes either.

All the cables used are 18 AWG: we checked and none are the slightly thicker 16 AWG wiring used for less resistance, heat and great efficiency were used in important places like the CPU EPS12V and PCI-Express cables. Usually only more premium PSUs offer 16 AWG though, so it's no fault of BFG's and, what's more, the peripheral connectors kept the same wire gauging too, unlike Corsair's CX series which uses thinner again.

Each of the four rails is nicely divided too: both PCI-Express cables get a rail worth 20A each, as does the CPU 8-pin connector, which should be certainly enough for all of them. The ATX and peripheral connectors round things off by sharing the last rail between them.
