5 out of 5 eggsCan't complain

Pros: This power supply worked 24/7 through New England hot summer days and cold winter nights, in an environment rich in dust, cobwebs, and cat hair, for SEVEN YEARS.

Cons: Didn't last forever :P

5 out of 5 eggsWorks great

Pros: Works great did not have any issues.It had enough cables to get the job done.Put behind the cause with plenty of room.OK that's a like it was kind of cramped but what do i know what i`m doing when hiding cables.I know how to build them.Not hide cables.

Cons: Not modular.I really wish it were modular because they are the way of the future.You use only the cables you need an put them away.This does not give you that option.It should cost less to do that rather than more.I hope in the future this is possible.

3 out of 5 eggs1 out of 2 bad

Pros: - Seems well built by weight (kinda fooled me into buying #2)
- Price
- Can power a small entry level gamer
- Turbo fan on/off switch
- Decent number of connectors for the price

Cons: - Quality control (a lot of units burning up as soon as they are plugged in)

Other Thoughts: Purchased one for a client sometime ago. It is still running fine today. It's powering 1 HDD, 1 burner, 6 case fans, an AMD FX-4100, an AMD HD 7770, 4Gb's DDR3 1600, and a MSI 970 chipset.

In light to how well that system performed for the price, I built my wife virtually the same setup except with 8Gb's of ram. No sooner I plugged in the power cable the Topower PSU sparked and I was greeted by a cloud of smoke. Newegg issued me a refund and I picked up the LEPA N500 for a few $ more. So far that psu is doing fine for us. It's hit or miss, if you wish to test your luck, go ahead and click that add to cart button :)

5 out of 5 eggs

Pros: Price,no problems

Cons: None so far.

Other Thoughts: Bought it to fit on my modded g4 hackintosh case.Perfect fit and the fans on the front and back are ideal for that particular case. Great product

5 out of 5 eggsNice Drive

Pros: Gives an option for you to turn the fan up for higher speeds. However I placed it in a low end system. It works fine as I was more concerned about cost and performance.

Cons: Just a tad noisy but I cannot expect everything for what I paid.

1 out of 5 eggsSave yourself the stress

Pros: None

Cons: Ordered one, was DoA. RMAed another one and it shot out sparks as soon as it was turned on. Save yourself the time and hassle, use the shipping fees it'll cost you to RMA it, and buy a better one.
