I bought it cause it was cheap
4 out of 5 stars
I bought it cause it was cheap
I didn't have high expectations so I wasn't disappointed.This is a basic no frills unit, feels light compared to my old power supply, maybe improvements in technology make this possible or cheaper materials? if your old unit has extenders/extensions/adapters keep them cause wires lenght is minimal. There are 4 wire groups coming out of unit with the following connectors 1)20 pin connector + 4 pin connector; 2)4 pin ATX connector; 3)molex 4 pin + sata 15 pin; 4)molex 4 pin + molex 4 pin + sata 15 pin + floppy 4 pin.

5.0 out of 5 stars Excellent Power Supply. Highly Recommended for Compaq Computers

I added this power supply to my Compaq Presario S5000NX. It was a perfect fit. It wasn't designed for the Compaq computers, but it does work with them easily. The original power supply had the cooling fan fail which caused the power supply to overheat. Eventually causing it to burn out. This power supply is very quiet and operates my PC like the original unit used to before it went down.

4.0 out of 5 stars Can't beat it for the price.

This power supply worked perfectly for my son's older tower PC. The exhaust fan blows out the front, instead of down on the CPU, like the one I replaced did. It gives plenty of power for the 2 250gbt hard drives in his system. The only reason I didn't give it 4 stars is because it only came with s SATA power connectors and his DVD multi-drive is SATA, as well as the 2 hard drives. Can't beat it for the price.

3.0 out of 5 stars Power Cord Not Included!
Reviewed in the United States on December 20, 2014
Verified Purchase
Order and shipment were completed with the usual Amazon efficiency. I have only had it about two weeks and so far so good. It installed quickly, supports my SATA hard drive and MOLEX CD/DVD drive. No complaints on the function.

However, IT DOES NOT COME WITH A POWER CORD.

I am a bit of a geek and assemble my own desktop computer using components such as the motherboard, RAM etc. purchased separately. So I had several compatible cords in my closet. But the description should indicate that the power cord does not come with the unit.

5.0 out of 5 stars A solid upgrade
Reviewed in the United States on April 9, 2013

This is a solid choice in a standard computer shell for an upgrade. If you need a new power supply or have maybe upgraded a graphics card or something that wants more power then this just might be the one for you.

Pros:
-Lots of power connectors
-Long power lines letting your route power around part instead of over them. (the motherboard line is at least 18" long I would say, my old one was about 8". a real pain!)
-Both SATA/RAID and standard 4pin connectors on each line.
-Lots of mounting screw hole, seems like it would fit into many boxes.
-Extra connectors for PCI, PCI-X cards if you have one that needs power.

Cons:
-Fairly loud compaired to my old 250W, but its almost twice the power so that is probably why. A bigger power supply is going to require more cooling afterall.
-While the mounting screws aligned with my case, the small bump-out where you plug in your power cord, prevented me from getting the last one in without modifying my case.
-No power light showing that it has power, if you even care about that.

5.0 out of 5 stars It works, great price too!

Well, its a power supply. Nuttin fancy, but it works and for a great price. I just need power. It took me a bit to figure out that the 24 pin cable end splits apart so it can fit the 20 pin connector on my motherboard. I had a node blocking the way so that I couldn't fit the connector because it was too big, and I sat scratching my head for a while...but the extra 4 holes slide apart to become a 20pin. DUH, me!

Item got me power to my old P4 machine.

1.0 out of 5 stars Did not receive Kentek Power supply, and stopped working after 6 weeks
Reviewed in the United States on February 10, 2013

In hindsight, I should have returned the unit immediately when the brand did not match the advertisement. I received a HongYe power supply instead of a Kentek. Since I needed to get my PC running, I decided to use it. Now it no longer will allow the Motherboard to boot (fan runs). I switched it out with a 4 year old raidmax 400W from another pc, and it boots fine. Return period just ended about a week ago. Last time I accept a delivery that does not match my purchase, no matter how desperate I am.

5.0 out of 5 stars Worked great for me

I bought this computer power supply and turned it into a DC power supply for my RC car battery charger. It now makes 12volts of solid power for my DC charger. It has a slight voltage drop at full load, but very good for the price. I am not using it the 99% of people will, but I am working it hard, I am drawing about 380watts of power from it when I charge TWO 11.1v 4400mah Lipo battery packs. It gets warm but never stops putting out the juice.
