5 out of 5 eggsGood low cost supply

Pros: Inexpensive
Great air flow

Cons: None

Other Thoughts: I've had these in 24/7 operation in a general purpose workstation & a file server for almost 2 years without a hiccup. The advertised wattage may be a little optimistic, but the supply is rock solid if used in a 400ish watt application. Definitely a good value.

1 out of 5 eggsCheap supply

Pros: Cheap and silent.
First one still running after 3 months (not a gaming PC)
That's it for the PROS.

Cons: Second one blew after 6 or 7 times using it. Sparks came out of the back of the computer and the thing died.
Funny thing is I went through all 14 pages of reviews and even with all those bad reviews I never saw any comments from the Logisys people.

4 out of 5 eggsDoes the job

Pros: Has a enough connectors for a low-end system. Large fan.

Cons: 4-pin connectors when separated are bound a little too close together, but I didn't need the second connector. Connectors didn't fit onto motherboard and peripherals as smoothly as higher-end power supplies I've used.

Other Thoughts: Quality relative to price. Can't complain at all. It works fine.

1 out of 5 eggsWorks like dirt

Pros: Quiet. That's it

Cons: Stop supplying power within 30 minutes to an hour of use. Can't leave computer idling or in sleep mode or else gets overly hot. Just completely worthless. Wish I could return it but it came with a combo so I'm stuck with it as a paperweight.

Other Thoughts: Don't cheap out

1 out of 5 eggsArrived DOA

Pros: None, though perhaps I should say that the fact that newegg will ship a replacement is a pro?

Cons: DOA

Other Thoughts: No power at all. Hard to understand how this leaves manufacturing without some sort of check.

1 out of 5 eggsHalf dead in less than month

Pros: Still fuctions on the 230v for now...hope to get a new PSU in next week.

Cons: Came with a Bundle deal that i ordered on 2/15/14. hasnt even made it a month and it has half died. It fails to turn on when with the normal US voltage(115v) selected. it turns on the shuts right back off. reset the cmos and everything.

Other Thoughts: Really you get what you pay for. If you are doing non intensive computing then this one may be for you, but i dont recommend anything demanding with this psu.

3 out of 5 eggsLow Priced!

Pros: So upon building this rig I like the size of the fan, connections LOOK like there is enough. 550Watts seems more than sufficient for this build.

Someone included in their review: "The lack of the 6-pin Graphics connector". This probably due to the lack of multiple rails to fuel such a connector (this power supply clearly states in specs that it has a single rail, also notes that the 12v supplies 25A which is typically needed for the graphics alone!!!). In higher priced model Power Supplies they do have such a connector! I have or have owned a dual rail Logisys power supply years ago for this reason alone, to power a power hungry Nvidia video card!

It works AS described, long as people read the Specs they will see what is lacking, this is a base line power supply pretty strong really other than maybe the fan issue, fans never seem to last however!

Cons: After looking closer, my SATA DVD Burner, and SATA HDD are seperated a fair distance apart. I found the small 3.5" floppy drive power connector, and the good ol' 4pin molex that is a thing of the past now in new builds (only need 1, maybe 2, 1 from each rail if the power supply has more than 1 rail). I found after installing everything running the wire. I went to plug in the power to my HDD, and the power cable I mistook as SATA power cord was a 2x 4pin molex...

Other Thoughts: To Newegg:

Luckily I had an old-school 4pin to SATA power. Otherwise I would have had to move my HDD from it's installed state to under the Burner less air flow, pain to install conveniently in the case included in Newegg's bundle. I would suggest reading more into the included power supplies that Newegg may put with their bundles. Initially there are enough connecters for the bundle to work correctly, however convenience is taken away due to the lack of SATA power plugs (the only 2 plugs are off the same rail (wireset) and about 4-6 inches distance once installed. So if Newegg offered a 4pin to SATA power adapter for $5 (wow it's $3 to ship such a little item?) to allow the Bundle to be even better!

1 out of 5 eggsdoa
