Pros: SUPER QUIET!!. Build quality looks solid; powers the whole pc without a hitch. Great efficiency and solid warranty a plus.
Cons: Fan made a ruckus initially after some internal wires got in the way, nothing a tweezer and 2 minutes of my time couldn't fix.
Other Thoughts: They include plenty of velcro strips to tie down the cables. We didn't have this luxury included back in 2001. +1 for great accessories.

This user purchased this item from Newegg
Pros: 550 watt continuous, included Velcro straps and zip ties are quite a nice addition, nice finish. Quiet, like all power supplies with 120mm fans.
Cons: On first boot, the 12 volt was quite low (11.7). My system seemed to work with it, but a few weeks later, I started getting random restarts. I checked the 12 volt again and noticed that it had slipped down about 0.2 more volts. I was not drawing more than 150-200 watts of power. Eventually, my memory (which has worked fine for months) died, spitting out tons of errors on MemTest. Of course this happened just after Newegg's 30-day return policy. I will be contacting the manufacturer (with my fingers crossed).
Other Thoughts: Other voltages were also low, but not enough to RMA it for. If the 12 volt (and other rails) were within acceptable range, I would have given this 5 eggs. It seems like a very nice, solid power supply with little extras that you don't see in other units. I had high hopes for this unit. I'm sad to see it didn't live up to it's reputation. If BFG's customer support blows me off, this may well be the first and last BFG product I buy.

This user purchased this item from Newegg
Pros: I have been running this sucker for over a week now. Quiet as can be and is definitely generating enough power for my gaming rig. I loved all the sleeved cables and BFG even provides you with Velcro and cable ties so that you can organize everything inside your computer. Definitely recommend this PSU.
Cons: None for now.
Other Thoughts: My motherboard (AM2+/AM2 NVIDIA GeForce 8200 ATX AMD Motherboard) wanted an extra 8 pin connector. This PSU didn't have it. But my motherboard's manual said the extra 4 pin should still be sufficient...... and it is.
