5 out of 5 eggsGood for the price.

Pros: *Performs well, replaced a dead psu in a old machine that i been using as a server.
*Running strong no issue's for over 4yr's.

Cons: *Kinda loud
*Not a great psu.

Other Thoughts: *Not sure if same version is still being used.
*For 30$ you can't really go wrong. If your looking for something better then spend the money for something better. If your looking for a cheap replacement then it's perfect.

1 out of 5 eggspsu please dont fail me now

Pros: dual rail, and 24pin

Cons: it died on me after the second week

Other Thoughts: was cheap so i cant complain that much, not worth spending 10 bucks to send back to just half to go through the whole process again, I only had one hd going, an asus radeon 5450 video card, 1 120 fan a 92 mm tornado, mb msi 880gm-e43, and a dvd burner. I bought a themaltake at 430 whats and 5 year guaranty, no problems so far

2 out of 5 eggsOK

Pros: Gets the job done.

Cons: 1. Super loud. I'm not kidding.
2. Somewhat cheap feeling, very light weight.
3. Only the mobo rail is braided, makes for messy case
4. only 1 sata connector

Other Thoughts: I'm really not a super picky person, but this baby is loud. It is even worse when tucked against a wall and the sound really tends to resonate. i replaced this with a thermaltake TR2 430w, which is a tad pricier but much much quieter.

5 out of 5 eggsMoar Power

Pros: does was it says

Cons: unbound rails ... manually binding is the only way to keep them from draping over heat sinks or other heated components.

Other Thoughts: nothing wrong with a decent cheap PS
