NeoPower 650 Blue


It was not so long ago I was in the market for a new power supply, and after long consideration, I settled on the original Antec NeoPower 480W. The original NeoPower is legendary for its stability, and the unit I have still runs strong in my secondary...

The contents of the package include the power supply, the screws and various cables. Physically attached to the PSU are the 24-pin ATX cable, the 4-pin ATX cable, an 8-pin PCI-E cable, and the 8-pin EPS cable.

Antec NeoPower 650 Review


To the educated masses, power supplies are the necessary evil close to the top of the build list when specing out a new machine. Unfortunately, for the rest, power supplies seem to be an afterthought in the build process and often, what little budget...

Component cables reduce wire clutter ; Stable rails ; Active PFC ; Very quiet ; Powder coated finish ; Three 12V rails

Only four SATA connectors ; No RPM monitoring for the fan

Antec has consistently offered high quality power supplies, and the NeoPower 650 does not deviate. The component system offers to reduce wire clutter, but for a full tower case, as in this build, all the cables were used except for the second PCIe...

I have several Antec Power Supplies that still work, but are underpowered or have too many hard wired older connectors that are becoming obsolete. In 10-15 years I've had one Antec PS go bad & it was promptly replaced with BETTER model, no extra...

Quiet. Modular design keeps excess cables out of computer. You can order additional modular cables from Antec Store. I just built a new computer with all SATA powered drives, 2 DVD plus 6 HD. Ordering 2 more SATA modular cables, allowed me to install...

Newegg doesn't stock them. It looks like Antec is the only source ; Antec lists the extra cables as spare parts, instead of accessories. A phone call to Antec put me on the right path to order the other cables I wanted. The extra cables are ONLY...

So, so, soooooo quiet! It doesnt even sound like there's a fan in it ; The air the fan blows isnt even warm, and it's been pretty hot out lately ; Modular, although I kinda wish the only permanent cables were the two power plugs ; Cable length is...

Fantastic PSU.


Really great fit in any Antec case, very powerfull although trying to hide the 24 pin cable between the Plate and the Cover is a little difficult...requires more then 1 pair of hands the first time...but there after its easy once the cables have been...

Very good length of cables, Great sleeving, pretty quiet and cool

wish it came with 2 more Native PCIe modular cables. and the fans could run a little faster

Excellent Cable Management ; Plenty of power ; Quiet

Catastrophic failure


Googling Antec PS failures seems to return a large number of instances where ANTEC supplies fail in combination with Asus mobos. While this failure is not of the catastrophic variety it's worth considering

Quiet, efficient, pretty blue light. I was being facetious when I wrote 'pretty blue light'. Actually there are no 'pros' since it was merely performing as advertised until it died with a sizzle and a bang

Failed catastrophically at 2 years, 2 months; smoke, sparking, etc
