5 out of 5 eggsSix years and counting.

Pros: modular cables are a nice option for keeping things neat and maintaining good air flow.
the fan is still smooth and quiet
runs cool

Cons: No cons for me so far.
it has split 12V rails, 216W per rail. not a con for me but could be for some.

Other Thoughts: I purchased this on 4/4/2010 I am assuming it hasn't changed, it looks identical and has the same specs. it has ran 24/7 almost the entire time running security camera software and as a media server for home theater. it has never skipped a beat. I'm running an i5, 4 hard drives and now a gtx 950 card. It runs very cool except on extended bench marks even then it only gets warm.
what more can I say, it has functioned well and has proven reliable for me.
I am now looking at purchasing another for a new build. or, maybe another Seasonic I purchased one of those from Newegg on 9/22/05 and it's still going strong.
anyway, do not purchase a cheap power supply. it's about the only component in a computer that isn't quickly outdated. more importantly, the function and longevity of your entire system depends on it.

4 out of 5 eggsWorked until i didn't

Pros: Price wasn't bad at the time about 65-70 bucks had all the connectors i needed. real quiet and modular. Up until it quit working never had a issue with it.

Cons: 3 year warranty some thing shorted out on year 4. Don't know if it took any thing with it. I figured it should have lasted longer than 4 years in a mild computer that only pulled about 300-400 watts when running games.. I still have some no name PSU's what still work and they are over 10 years old. but they don't have the newer connectors.

2 out of 5 eggsGood for the first few years

Pros: - PSU ran very well for the first 2 years of everyday use.
- Fan is relatively silent, even under heavy load
- Semi-modular makes cable management easier

Cons: - Fans started to get noisy around third year
- PSU died around 4 years of use. Volts checked out okay but computer wouldn't post.

5 out of 5 eggsGot 5 years of decent and demanding service

Pros: The unit lasted about 5 years of very regular use and intense use under hot tropical conditions before dying. When it died, it was simply a dropped power_good voltage. The final voltage checks were 3.41v, 5.05v, 11.25v, all within spec.

Also it ran very quietly until the end.

Wire wrappings and the extra wire pouch were both nice extras, as was modularity. Definitely appreciated those aspects over the years.

Cons: I felt there was some instability in the system throughout the last 5 years when under heavy load. Crashes every few hours were common. Might've been game code, though, it's hard to say which was the culprit, but it happened over a few titles, so I'm suspicious of the PSU.

Other Thoughts: Bought a 500w model for a system that only really needs about 360w.

Overall, I would call it a mid tier PSU. It lasted through a lot and didn't take anything out with it. 5 years is good enough for just about any component for me. I'm satisfied with my purchase. I'd not hesitate to recommend this model and brand to others, though I'll be trying a Corsair for my next PSU.

1 out of 5 eggs

Pros: It seems to be a well constructed PSU.

Cons: I have had two of these PSUs fail on me. Both failed around the three year mark. The first one had a component failure, I could smell the fried part. The second would power up but the fan spun very slowly with no voltages at the connectors.
