Works - no issues

Tech Level Tech Level: somewhat high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: First, this build was for work and my budget was $500. Seasonic has a good reputation and went with a low cost PS (every penny counts with a build like this). There were plenty of connecters, molex and SATA, and had no issues.
Cons: The PS is made out of sheet metal, bent to form a box. I noticed one of the sides was not properly alligned and not sure why because Newegg packed it very well. I pushed on that side with the handle of a screw driver and it snapped back to where it should be.
Other Thoughts: I got the build from a discussion forum on tomshardware and modified it some:
Motherboard - ASRock A780LM AMD Micro ATX
CPU - AMD Athlon 64 X2 5600+ Windsor AM2 Dual-Core
Memory - G.SKILL 4GB 240-Pin DDR2 800 (PC2 6400)
Hard Drive - Western Digital Caviar SE 320GB
CD ROM - LITE-ON Black DVD-ROM IDE iHDP118-08
Case - Rosewill R101-P-BK MicroATX Mid Tower
Power Supply - SeaSonic SS-300ES 300W ATX12V

Probably a dud (sort of DOA)

Tech Level Tech Level: somewhat high - Ownership: 1 day to 1 week
This user purchased this item from Newegg
Pros: In theory this PSU would be a good fit for low wattage setup. 4-SATA power plugs.
Cons: Sadly this one arrived (almost) dead. I hooked it up and testing the box I was building. Then a few days later when I actually built the box there was nothing. After some troubleshooting I figured out that once more than one drive was plugged in the PSU failed.
Other Thoughts: This was a low wattage system, the PSU only needed to power an Intel Atom board, a small case fan, and HDD's. Clearly 1xHDD and the chip, board, fan were nowhere near 300W. I assume I just got a dud. On the plus side when it was working (with one drive) the whole system only used 43Watts.
