Summary: Little loud at sometimes when I'm playing some high def video games. But other than that, works really well. I got it after my 850w antec died, tried to get something more closer to the wattage my computer needed. Works like a charm! I searched the internet and they don't stress enough, that when you build your computer-- GET A PS THAT HAS A LITTLE MORE THAN THE WATTAGE YOU NEED, NOT SOMETHING THAT IS OVERKILL.
Summary: I've used a BP550 in most of the builds I've put together for our office and am always reminded of how much less frustrating it is to cable a computer when you don't have an extra 4 feet of dead useless cable floating around in the case. A solid contender at any price the only complaint I have is that the GPU power cable is not modular as we don't use cards that need dedicated power leads.
Summary: Hello, I chose 3 stars becuase although it works and i have used it for about a year, it is definitely not for gaming. For awhile I had to old NVIDIA Geforce 7600 GT and it worked smoothly! When I put in a Asus Radeon HD 6850, it will crash after an hour or so. The Power supply meets recommended requirements yes, but the power from the box is declining. I am currently in the market for another power supply so it may work on my graphics card and not crash.
Summary: I bought this to replace an older failing BFG supply. Glad I am back with Antec. It works perfectly, it is quiet and delivers steady voltages across all lines. The only thing is I wish it had more options in the modular lines provided, perhaps one with both SATA and old school MOLEX on the same line. But it is a small detail that does not affect its so far rock solid performance and silence.
Summary: I needed a new PSU and opted for this one based on the reviews. When my computer still would not start, I sent in for a replacement, and got a second one to test with (I love Amazon's replacement policy). Eventually I realized the motherboard died as well. When testing with two of these power supplies, one of these caused the system to freeze much faster than the other. I do not know if this is common, but it seemed the juice from one was fairly greater than the other.
