BFG LS-450 Power Supply Review

Hardware Secrets Golden Award


LS and MX are sister power supply series from BFG, with models from MX series coming with a modular cabling system, a 120 mm fan and an auxiliary 80 mm fan on the rear, while models from LS series use a 135 mm fan and no modular cabling system or second fan. Initially both series used the same internal design, however this is not entirely true anymore. All models from MX series are manufactured by Fore Point (one of the factories from Fortrex), but LS-450 and the new version of LS-550 (marked as “LS-550 (New)” on their website, being the model currently available at are manufactured by Enhance Electronics. The old LS-550 and LS-680 are manufactured by Fore Point with the same design as models from MX series. According to BFG they will move all models from MX and LS to Enhance in the future, and when this happens units will be either released with new wattages (e.g., LS-700 instead of LS-680) or will have the name “New” added to their name.

Enhance Electronics is the manufacturer behind power supplies from Akasa, Real Power Pro series from Cooler Master and TruePower Quattro series from Antec. Keep in mind that not all models from these two brands are manufactured by Enhance.

LS-450 is a small power supply (5 ½” or 14 cm deep), has a 120 mm fan on its bottom and has active PFC circuit.

All cables use a nylon protection and all come from inside the power supply housing, as you can see in Figure 2.

The main motherboard cable uses a 20/24-pin connector and this unit comes with two ATX12V connectors that together form one EPS12V connector.

The reviewed power supply comes with five peripheral cables: one with one six-pin auxiliary power connector, two with three SATA power connectors each, one with three standard peripheral power plugs and one with three standard peripheral power plugs and one floppy disk drive power connector.

All wires are 18 AWG, which is the correct gauge to be used.

This unit presents a satisfactory number of connectors for an entry-level or mainstream PC with only one video card installed.

All cables are very long so you won’t have any trouble installing this power supply inside full-tower cases: the distance between the power supply housing and the first connector on each cable is of 21 21/32” (55 cm) and the distance between each connector on cables that have more than one plug is of 5 1/8” (13 cm).
