LOGISYS Computer PS550ABK 550Watts ATX12V Power Supply With SATA and 20/24 Pin connectors.

Pros: None!

Cons: Voltages off
Doesn't work

Other Thoughts: Ordered this piece of junk and it got here and my comp would turn off and on. So I knew that it was either a PSU or Mobo issue. So I got out my trusty PSU tester and low and behold the voltages where off! So I sent it back got a new one and it came back and it was messed up as well!!!

Don't buy this! It doesn't matter how cheep it is it won't work.

Pros: Power supply has been reliable with the one noted execption.

Cons: The fans. One of the fans started making noise after about 6 months of use. The noise got to an obscene level. I have alot of extra cooling, so I removed it. The other fan has now started making noise. Not obscene yet, but noticeable.

Pros: This PSU is a good bargain for sure, it ran my computer fine doing mild gaming on integrated graphics.

The price is fantastic.

Cons: 73% efficiency.

Can't handle a GTX650ti.

Loud.

Other Thoughts: Like I said, if you aren't doing heavy gaming, this PSU will work just fine, but you can't game with it, and it only puts out 400W.

Pros: Worked long enough for me to get my parts for my new build.

Cons: Voltages are all over the place. Hard drives kept kicking errors due to irregularities.

The fan started making an insane amount of racket after a few months.

Other Thoughts: You get what you pay for. There is a reason it is $30. I got it to throw in a box with some left over parts from old builds. Did the trick. I would never use this in a build with parts I cared about.

Pros: Cheap

Cons: Loud fan
Short life

Other Thoughts: I went through 2 of these in 6 months. Both of them died about 3 months after I bought them.
If you're tight on money and don't have a high end graphics card or CPU, you should probably be okay with it. Otherwise, fork up a little more money for more reliable brand.

Pros: Has been working 9 months when 3 other power supplies quit within a month's time.

Cons: Still working so no complaints.

Other Thoughts: I was trying to fix a computer for a friend of mine who lives in an old house with the screw-in fuses. Her computer was eating power supplies. I was starting to think that her house has serious electricity issues even though she had a decent surge protector. I decided to try one more, and tried this one, been working for 9 months now.

Pros: Inexpensive and high enough watts for mid-range gaming.

Cons: Cheaply made, bearings and/or fan tends to go bad on them. May cause loud noises because of.

Other Thoughts: Decent enough to get by with, but don't put in high-end computers! Not reliably made as compared to higher-end PSU (i.e. Antec, Thermaltake, CoolerMaster, and Corsair).

Pros: About the only low priced power supply available for a mini server based on an older MSI board with that dreaded -5v pin on the ATX connector.
And work it does.

Cons: Damaged 4pin molex connector, resulted in constant rebooting when plugged into any internal 4 pint device.
Runs pretty hot. May be a concern if your cooling needs aren't met by your facilty air conditioning system.

Other Thoughts: Aggravated me quite a bit while troubleshooting, and eventually soldered on a different set of connectors and rebuilt the entire output side of the PSU, omitting the use of the damaged connector and adding another half dozen connectors to get to all the hard disks and the other hardware.

Note, you will need something like this to avoid those annoying MSI 'bad cpu' issues during boot (it happens on their higher end old boards if you don't have the -5v pin on there.) I also tested it on an old Intel 810 board for my own curiosity. That CPU also failed to detect with a non -5v PSU. It worked with this one. Word to the wise and to those who absolutely require an older system and can't find a PSU. This one should work, but you may require some hardware skill if things don't work as they should.

** It was on sale for sub 20 bucks when I got it.

Pros: Nice compact size, cable length works for desktop to mid tower sizes...

Cons: If your looking for a power supply for a full size tower or to power video cards, (in SLI or Crossfire) then this is not for you...

Pros: 2 fan's, long cables, plenty of power for everyday Systems

Cons: None

Other Thoughts: I have bought many of these, they always fire up right out of the box
