Overall Review: It was just as you'd hope it to be when it works

Great power supply. 7 years and still going strong

Pros: 7 years near daily use, back in my gaming days this would power my PC 12 hours a day, 8 of those hours gaming with a gtx 670. I've read about some comments recently of how Antec sucks. The only thing that sucks about this PSU is its standard plain look. Everything else is amazing! I'm hoping it'll power my PC with a Vega 56 , if it doesn't it'll finally be time to replace this thing. Other wise I have no reason to replace it, stable power!!!

Cons: looks

5+ years of usage and still going

Pros: I bought this PSU for a build I did back in late 2011. Pretty much all the original parts of that build have either been replaced or have stopped working, but this thing has just kept going without skipping a beat. It's been powering a high end gaming rig for 5+ years for at least 8 hours a day and it still works like new. Whenever this thing kicks the dust I'll be buying another Antec power supply, although at this point it'll probably outlast me.

Cons: It's ugly but that's about it

Antec BP550 Plus 550W Continuous Power ATX12V V2.2 80 PLUS

Pros: Nice clean modular cable setup
Worked great for 3 weeks.

Cons: The PS lost +5 after 3 weeks.

Overall Review: I bought this supply in 2011 back in th LGA 775 days. I was cleaning out my workshop and found it on a shelf. Plugged into a tester to recall what was wrong. 5 volts was still missing.
This was the first bad Antec product to ever fail on me. Now you know the story 6 years later. :)

6 years later, still going strong.*

Pros: Solid power supply. Runs quietly, and has a no fluctuations in power.
Currently:
+3.3V: 3.36
+5V: 5.00V
+12V: 12.06V

*No problems, after six years. Upgraded to dual 960 GTX video cards, and added more hard drives since then.

Cons: None
*After switching UPS battery backup units, when it kicks to battery I get a slight hissing noise from the PSU. However, no drops in voltages or anything, just a weird noise. Guess my UPS backup is worse than the one it replaced.
* Had to tighten the screws on the fan, it started rattling a little on spin up.

Overall Review: Won't know how much the 80 Plus helps until I see my next few power bills.

*Pulls 250-300W at idle, jumps up to 450W when in game. Measured using a Kill-a-watt adapter.

Longevity king?

Pros: LONG life, clean power, semi-modular

Cons: CPU power could have been about 1 inch longer to reach the plug on the opposite side of the motherboard easier

Overall Review: I've been using this PSU nearly daily for over 7 years. I'm finally in the market for a new unit, not because of an outright failure from this one, but simply because I've started to notice it losing .5-.6V on the 12V rail under load. I've never had any stability issues with it, the lower voltages are rock steady. I may just be pushing it a little hard for a 7 year old unit. I've got an FX8320 clocked at 4.4Ghz, 3 HDDs, 1 SSD, a total of 6 120mm fans, and an RX-480 OC pulling power from this trooper of a PSU.

It's...Ok

Pros: cheap and gets the job done

Cons: causes my computer to freeze, black screen, etc.

Overall Review: I'm sure its fine to buy, I think I just got a little unlucky. The freeze problem isn't too recurring, but I have traced the problem to my PSU, and it has been doing it for a few years now.

Still going strong!

Pros: Fantastic power supply!
Lots of connectors and it's modular!

Cons: Nothing

Overall Review: I'm only writing this review because I was checking my order history to see when I ordered this. This power supply has powered 3 different computer builds:i
i5 760 with HD6990
Xeon E3 1225v2 with R9 290
i7 6700k with RX480

It's been going strong well over 6 years now!
