Pros: 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.

Cons: Failed catastrophically at 2 years, 2 months; smoke, sparking, etc.

Other Thoughts: 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

Pros: This supply has plenty of power for my build and looks great in the Antec 900 case. The blue lights matched my case perfectly. The modular cabling is a nice touch and helps with cable routing. This 650W supply has enough kick for what I needed. My voltages look great as well. I didn't have any problems but for someone that may consider using this supply in a full ATX case you may need to consider looking at cable extensions. I know my power cables for my DVD drive were getting close to being at the end of their reach.

Cons: None that I have found yet.

Other Thoughts: Antec 900 case
ASUS P6T motherboard
Intel i7 920 (OC'd)
Corsair XMS3 DDR3 1600 (3 X 2GB)
2 X 150GB Velociraptor hard drives
EVGA Nvidia GTX260 superclocked edition
Antec Neopower 650W power supply
Samsung DVD burner

Pros: Excellent PS for Antec 900 case. Very Quiet and the modular cables are nice to have. Plenty of power for my system.

Cons: None

Other Thoughts: EVGA 132-YW-E179-TR - 790i SLI
Intel Q8300
Crucial Ballistix 2GB DDR3 2000
XFX GTX 285
Antec NeoPower 650 Blue

Pros: Magically fixed standby / resume and overall stability issues with my system. System could not come out of standby would occasionally fail to POST with 500W PS. Solid as a rock for months now.

Cons: Enough with the LEDs already.

Other Thoughts: Currently runs Giga-byte GA-P35-DS3P with nVIDIA 8600, 6 internal SATA, 2 IDE optical, 1 eSATA, with dual-core 1.6 OC'd to 2.4, 2 GB at ~1066, 10-12 bus-powered USB devices, 2 case fans & Zalman CPU fan.

Pros: quiet; has plenty of power for my quad core and gtx 260; looks nice in my case

Cons: none

Pros: Neat! Modular! Quiet! Nice blue light, matches the Antec 1200 case well. Unfortunately if you have a bottom mounted power supply, you will likely want to get an 8pin adapter. No fault of the power supply, but something to keep in mind.

Cons: None, worked as expected.

Other Thoughts: Plenty of extra modular cables for build changes. Looks great, and it is hard to tell if it is running since it is so quiet. If you have the Antec 1200, get a 12" 8pin extender so you can run it behind the motherboard instead of across the side of the video card.

Pros: I haven't owned it long, but so far is dead silent and runs cool. Excellent modular wire system lets you add the wires that you need and no more.

Cons: None so far.

Pros: Fired right up straight out of the box. LED is not too bright. Enough power for my gtx 260 and my 2x250mm fans without any issues

Cons: none

Pros: Bright blue LED fan.
Fan is large, fast, and quite.
Modular though slightly limited connectivity.
Top quality Brand name.
POWERFUL!!!

With the 3 +12V rails all at 19A each and Active PFC to boot, it's hard to call this any less than a solid gamer PSU that will LAST! Reading the wattage notes on the side shows that it will sacrifice the lesser rails in favor of the +12V rails if it closes in on it's wattage limit. This is a nice feature for those looking for either system format: Gaming or Multimedia Center. I'm personally using it as a combination high-end gaming and light multimedia so it's dead solid perfect for my build.

Cons: Nobody in there right mind or with half a brain should even THINK about SLI or CFX with this PSU. Reasons: 1x 6 pin + 1x 6+2 pin PCIe power connectors. Can run just about any single PCIe GFX card on this or at most 2x HD4850 in CFX or a single HD 4870x2. As power hungry as nVidia cards are I wouldn't trust it to handle SLI for any nVidia cards or the GTX295.

Other Thoughts: Don't be an itchy trigger finger buying just any PSU. Do your research and look for wattage calculators that will also do full layout on volt rails too. There are free ones on certain tech sites.
