Antec BP550 Plus 550W Continuous Power ATX12V V2.2 80 PLUS Certified Modular Active PFC Power Supply - Intel Haswell Fully Compatible

Pros: I have had this since march of 2010 and it is still working fine bought another one of course for another build for my daughter I know I can trust it for reliablity and long life is what I expect when buying a PSU I buy others for other peoples build though not my personal builds

Cons: none that I can honestly think of

Overall Review: hioghly recomend this PSU especially if it is on sale like I just ordered another one at good price voltages all test in specs little fluctutaion compared to other brands

Pros: Built my rig almost a year ago and it has been running near non-stop since. I have had no issues with it, it supplies plenty of power and doesn't add any noise to my case. The three 12v rails are a definate plus. One rail for the CPU, the other 2 rails for video cards.

Cons: Wish the mobo connector was a little longer.

Overall Review: This is the first modular power supply I have purchased, and it is well worth the money.

Pros: I haven't had any stability issues and I like the modular cabling. Here's what it's running: AMD Athlon 64 x2 5800+ Brisbane 3.0GHz Nvidia Geforce 9800 GTX+ SSC (EVGA) 2 SATA hard drives 1 SATA DVD ROM 3 120MM Fans 2 DIMMS

Cons: Very minor voltage fluctuations. Im sure if you wanted rock solid voltage, you would spend >$100 for a power supply.

Pros: Love the modular cabling. My case is so tidy! The braided cable looks great in an open-sided case and is stiff enough to force into the corners for great airflow. The 120mm cooling fan is nice and quiet. Haven't had any problems with power fluctuations or anything, though I'm not running anything heavy. Seems like a quality, well-built piece of equipment, and it's at a great price. Currently running: *ATI Radeon 3850HD 512MB *AMD Athlon 64 x2 5000+ Brisbane (2.6 @ 3.0) w/ 120mm fan cooler *OCZ 2x2GB DDR 800 *DVD Burner *2x SATA HDD *3x 80mm LED fans, 1x 120mm fan, 1x120 mm LED fan, CFL light

Cons: I understand having the 20+4 pin cable non-modular, since almost all modern mobos use either 20 or 24 pins. Similarly, a 6+2 will be used in almost any power-user configuration (i.e. anyone who buys parts from Newegg). But the additional 4 AND 8 pin means that every common motherboard configuration will have one leftover cord. What they should have done is had the 20+4, the 6+2 and a 4+4. Then include another 4-pin as a modular cable. Also, and I'm not sure if this is an artifact of my case, but it seems like the SATA connections are on upside down. The way they are oriented I have to take the cable down to the bottom of the case, then back up. In my big case I have to do a lot more wire routing than I would need to if the connectors were on the other way around.

Overall Review: Besides a few minor quibbles, this is a great piece of equipment!

Pros: - No issues with my build Z68 mobo i5 2500k CPU 1 SSD Sata III 1 HD Sata III 1 ATI 6970 4 cooling fans

Cons: None

Overall Review: Modular design helps reduce rats nest..

Pros: Plenty of power for an overclocked Phenom II X3, Corsair H50 water cooler, 4 hard drives, 2 optical drives, a floppy drive (yes, it still gets used), 2x2 GB DDR3, Radeon 5750, a plethora of USB devices, and 4 120mm fans. Having the modular cables while adding more and more to this system over a few years is nothing short of a blessing! Best of all, no annoying LEDs!

Cons: um... it's lasted longer than the rest of my system?

Overall Review: This power supply has essentially powered 3 different configs. The one listed in the pros, and a couple less power builds. And while searching for a new power supply for a new build, I realized I never reviewed this in the over 3 years that I've owned this. Yes, really. 3 years. And it's still going strong. I will most definitely buy another one.

Pros: Comes with plenty of SATA and MOLEX power connections which was important to me, I have tons of fans and my CD drives are still IDE and Molex powered. The modular design is well done. I only needed the PCI-E, sata and molex connections. I didn't need used for another set of molex with 4 pin floppy and another sata set. So modular was key to keep the case as clean as possible. I went from a BFG 800W(burned out) to this 550W and it powers all the fans, rom-drives, HDD, 2 video cards and the 7400 Wolfdale under full load with no issues.

Cons: very basic design. It is nothing worth showing off in a clear case or side window.

Overall Review: Great price, well packaged, simple basic design. I would say it is every bit as good or better than my previous BFG 800W power supply. We will see if it lasts longer than the BFG.

Pros: Modular cables are cool, fan rins quiet,and is internaly powered meaning one more free fan connector on MOBO. Have it in a system that eXtreme Power Supply Calculator calculates at 525 min 575 max at 80 % Utilization at 100% Utilization 629 to 679, And It seems vey stable* 550Watts value is-continuous power meaning, (peak power formula is RMS watts times 1.41) so 550 X 1.41 = 775W Peak power which if true makes this an incredible value.

Cons: I used my digital Occiliscope to read the true power coming from the outputs, long story short I get a total peak value of only a little over 585 Watts 37 amp from 12V rails and 34 0n 3.3/5v rail. So 444 Watts for 12 volt and 141.2 for a total of 585.2 Watts meaning whats printed on product seems to be peak power not cointinuous ( My reason for taking an EGG)

Overall Review: B+for power A for Price / Value A+for ease of use ie lables and directions A+++for noise level GOOD ITEM WONDERFUL FOR 550 peak power
