Pros: Cheap.

Cons: Cheap.

Other Thoughts: The ATX power supply slips out of motherboards like it is coated in a lubricant. I would never recommend this product for someone to use in a computer build.

Manufacturer Response:

3 out of 5 eggsSo far so good

Pros: Looks well made. What i can see of the parts inside looks ok. Nice cable wraps. Voltages look stable so far.

Cons: One of the middle of the wire SATA drive connectors is UPSIDE DOWN! this makes it impossible to connect two devices that are near each other without flipping something over.

Easily done in my case. But for a lot of setups that would be impossible.

Two of the rear screw holes are stripped out.
No big deal but still...

-2 stars total for those two things.

Other Thoughts: So far so good. Good price. Got here asap took 2 days total!

It was an emergency replacement for my previous power supply which blew a cap after 3 years of 24-7 use.

5 out of 5 eggsIt works

Pros: Looks nice. Wires wrap looks good. It was not DOA so that is always a plus. Cant really say to much about a 35 dollar power supply.

Cons: 8 pin cable was not long enough to be run through my cable runs. Had to do a straight shot out of the PSU to the 8 pin on my MOBO.

Other Thoughts: Would have been nice if they included the screws to mount it to the case. I had several around so not a big deal to me.

2 out of 5 eggsNot Reliable Enough For Me

Pros: Well; it worked for 1 year and 1 month.

Cons: Big Deal; I could of used a $30 power supply and gotten this kind of longevity. I will no longer be using this brand in my Business machines, as far as I'm concerned - - - - Thermaltake is the brand that I will now use for all of my Business PC's.

Other Thoughts: Needless To Say - - - I Am Not Happy!
One of my business customers called me this morning about
their 1 year old computer that I built for them on 11-26-2013.
When I repaired today; this Power Supply was dead, and I will
eat the cost of the repair - - - - - To Save Face.
I replaced this unreliable junker with a Thermaltake P.S. which cost me $39.99.

Manufacturer Response:

Thanks for the feedback. We will pass it along to our QA and Design teams for further investigation.

5 out of 5 eggs5 Years of Service

Pros: Has enough cables for most uses
Is quiet
Doesn't build excessive heat

Cons: The cables can be stiff and a little difficult to position, making this a poor choice for smaller cases.
One cable is live and uncovered and in my case, would shut it down when it touched the case. (I never determined what it was supposed to power)

Other Thoughts: I used this power supply for 5 years with little trouble but for some wrangling of the cables to keep them from resting on my video card or pressing against the motherboard.

I had to replace it earlier this year due to some of the cables developing shorts and no longer providing full power to several components including my boot drive, my optical drive, and I think my motherboard, too.

If you have good space in your case and aren't planning to upgrade too often, this should be a solid power supply for most needs. If you're going to be going inside to upgrade or replace components to keep up to date, however, the cables stiffness might cause issues, and maneuvering them might be what caused mine to eventually short out.
