5 out of 5 eggsSeems solid

Pros: It is really working for me. I made a costume itx computer case from sheet metal from old scrap and this power supply works great. It is small and cheap, lets hope it keeps working for the years to come.

Cons: Does not take me on an epic quest full of adventure and pie?

4 out of 5 eggsWorks

Pros: Quiet, runs fine. 300w can handle more peripherals than 200w.

Cons: This is not a complaint about the SeaSonic, but be aware that unlike ATX, TFX is more of a "guideline". ALWAYS MEASURE YOUR CASE OR EXISTING POWER SUPPLY before ordering ANY power supply.

5 out of 5 eggsNice replacement for HP Pavillion

Pros: Installed in slimline HP Pavillion being used to send slideshow presentations to an overhead media projector. The PC would randomly restart while unattended; the message was "Windows has restarted after an unexpected shutdown". The SeaSonic PSU fits well, the cables are more than long enough (had to zip tie the excess) and have all the proper terminals.

Cons: Silver case color shows though black housing vents. A little paint or even black tape would fix this, if I cared enough to do it.

Other Thoughts: 300W is overkill for a PC that sends PPT to a projector, but the extra capacity brings peace of mind.

5 out of 5 eggsInstalled on Inspiron 545s

Pros: Very quiet. With the stock PSU, my computer was loud. Now, it's so quiet, that it seems like its not even on. So I opened it and saw the fan was actually working.

Cons: None.

5 out of 5 eggsGreat htpc replacement

Pros: It works. And it fits perfectly in my HEC 7K09BBA30FNRX case. I made the mistake of buying a case with a built-in non-standard size PSU, and while it did last me 3.5 years, it finally died. I assumed I would have to buy a new case, a new PSU and, while I was in the habit of replacing parts, I might as well get a new htpc build.

This PSU fit perfectly in my current case - the screws lined up and everything. Amazing. So I get to keep my current system.

Cons: None yet.

5 out of 5 eggsQuiet fan

Pros: I bought this fan based on recommendations as a replacement for a slim-case Dell Studio computer. Apparently, the Dell power supplies on the model fail after a couple of years. Once I installed the power supply and turned on the computer, I had to make sure the fan was actually running because it was that quiet. So far, I'm Very pleased with my purchase.

Cons: I don't believe it came with any screws. I didn't check since I used the ones from original power supply.

Other Thoughts: Replacing a power supply is very easy. If you've never replaced one of these, I recommend you noting where the cables are plugged in on the computer (maybe even take a picture) just to make sure you don't forget one of the components.

5 out of 5 eggs

Pros: Been working 1 month straight in a Teamspeak 3 and Minecraft Bukkit Server. 90% idle time so im maxing most of the time around 50 Watts

Cons: None So Far

Other Thoughts: If i had a spare case i would have just got a Normal power supply for the server but if all you got TFX case you make do with it and spend a little more on the power supply. I Know are small and dont have much but i would have loved at least one more molex and Sata Power connection

5 out of 5 eggsIt works

Pros: It works.

Cons: None, so far.

Other Thoughts: I purchased this to replace the stock powersupply in a foxconn RM3-H2 barebones(which seems to go out on everyone). Was worried a bit on the dimensions, but it fit perfectly. It's been a few months now and still chugging along with no problems so I can't complain.
