Reviews - BFG LS550 550W

As many of you will recall, I took a look at BFG's new LS series once before, when I threw the 680W model at the load tester to see if it would stick. Today, I've got the 550W little brother of that one by the ear, and I mean to lay a good old fashioned caning on it too using my handy dandy SunMoon ATE.

But first, as always, we'll get ourselves a good look at some fancy cardboard.

Those of you who read the review of the 680W model will recognize everything in the shot above. Except for the load table, it's almost completely identical to the info on the 680W box. Efficiency is given as greater than 80% typical, and though they don't mention it here, this model is 80 Plus certified. You will recall that big brother didn't quite manage to pull that off, and I'll be interested to see what happens on the load tester with this unit.

Once again, upgrading your PSU is simple! The back of the box is identical to the 680W model's.

Again, the last helpful side of the box lists some features of the unit. I'll make you all study the above picture to read those, as they're identical to the LS680 and I'm a lazy, lazy man.

Unpacked, the contents of the box are - surprise - almost exactly identical to the LS680. Except, now we only get a 550W unit, of course.

That little bag of goodies in the last picture has been unpacked for your attention. A bag of screws, some black zip ties, some velcro wire ties, and a power cord.

Sharing the same platform as the Fore Point built LS680, it's no surprise that the two models look identical. Maybe could we change out those silver screws for black ones, BFG? It would look way better.

As with the LS680, the load table has some weirdness to it. Not quite as much weirdness as the inside of my brain, mind you, but there's some there all the same. Like the 680W model, the 550W rating is given for the three main rails only. So, because of this discrepancy and my unwillingness to test to peak numbers, I will proceed as if this unit is rated at 550W in total.

The tentacle shot on this puppy is a bit more barren than the 680W model due to there being less cables to begin with. No extra SATA connectors here - you'll get four and only four of them on the LS550. 12V rail distribution is given in the manual of this one too, and it's no big shock the distribution is the same:

12V1: ATX, SATA, 5.25," and 3.5" Molex connectors
12V2: EPS12V/ATX12V connector
12V3 and 12V4: PCI-E connectors
