5 out of 5 eggsStill Strong

Pros: Very Stable
Low Noise
Long Cables
120 mm fan

Cons: non

Other Thoughts: I had to come back for an update. This PSU has been one of my best upgrades. My system has a Mobile Athlon 2500 clocked to 2.4 Ghz, 2 sticks of Patriot 512MB PC 3700 ram, 5700 Ultra video card, 2 HDDs, 2 optical drives, 2 cold cathodes, and 4 case fans, and an Audigy 2 ZS. Absolutely zero problems. Well worth the money you spend.

5 out of 5 eggsGreat PSU

Comments: I read quite a few reviews before I made my final decision. The PFC is what did it for me. There really aren't that many power supplies out there with this feature.
It is fairly quiet, and it runs my overclocked system with ease.
I just wish they offered PFC on their smaller units.

Comments: Very nice unit. The large 120mm fan runs quiet and moves a moderate, though not great, amount of air, and is fully user adjustable via the 3-pin motherboard fan header. Primary ATX and sub ATX+4 cables are wrapped in gloss black wire mesh. Unit is 120V/240V autosensing, and is made in China.

5 out of 5 eggsUltimate Flexibility

Comments: Can not say I am technically savvy, but this power supply appears to be terrific, although a little expensive. It has seeming unlimited connectors. Even with a permutation 4 SATA HHDs and 10 PATA HHDs, Optical Drives, Ati or Nvidia Video Cards and 2 Floppy, Zip or Card Reader Drives, there are still a few power connectors left for maybe a couple of HHD coolers, slot and/or case fans. Oh, it also has four of the new serial power connectors (great for those that dont realize "bare drive" means "nothing included but the drive itself").
