5 out of 5 eggsStill going strong!

Pros: - Modular cables
- Reliable
- Quiet

Cons: - Could use more connectors
- Cables could be longer

Other Thoughts: It's been 4 years and 3 months since I've purchased this power supply. The reliability of this power supply is astonishing.

This PSU has survived my last three upgrades. First computer was a Core2Duo 3.0 @ 3.6 with a GTX 280 and 7600GT, three 7200rpm drives, Audigy, TV tuner, and DVD burner. Second build just changed the cards to a GTX 470 and 9800. Third build changed the processor to a Core i5-750 2.66 @ 3.0, a HD6970 and 9800, 3 7200rpm drives, a SSD, and DVD burner. Each of these builds also had 4 to 5 case fans with LEDs.

I'm confident that this PSU will remain with me for my next build mid next year.

This system has been on at least 75% of the time I've had this PSU. Most of the time I am home the computer is under mid-heavy load with the GPU working nice and hard as I play my games maxed out. If the game does not require much attention to sound, I keep a video running on a second monitor further utilizing the CPU/GPU.

It's going to be hard to make me stray from Antec for power supplies after this beast.

1 out of 5 eggsCatastrophic failure

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

5 out of 5 eggsWorks well

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

Intel i7 920 (OC'd)

5 out of 5 eggsSuperb

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.

5 out of 5 eggsNice

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.

5 out of 5 eggsAbsolutely silent

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.

5 out of 5 eggsMore than I needed ;)

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

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.
