5 out of 5 eggsWorks - no issues

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

2 out of 5 eggsProbably a dud (sort of DOA)

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.

5 out of 5 eggsVery quiet

Pros: Quiet, works well in my small system

Cons: None if the power rating handles your needs.

1 out of 5 eggsshort mobo power connection

Pros: n/a - wasn't able to use

Cons: The power connection to the mobo wouldn't reach in my Lian Li PC-C37 case with a Asus M4A78-EM mobo.

Other Thoughts: Surprised no one else reported this problem in other HTPCs. Maybe they're using full size cases with the PSU directly over the mother board?

5 out of 5 eggsGood Small Power Supply

Pros: Using this in my HTPC. Works great, 80+ certified. 3 Year warranty is pretty good.

Cons: Nothing for this price and output

Other Thoughts: Good for a low power build.

5 out of 5 eggsGood product

Pros: The use of this PSU decreased PC (a little server) consumption from 78W to 65W. Previous PSU was a generic one.

Cons: None at this time.

Other Thoughts: Power requirements are by far overestimated. This PSU is a perfect choice for the vast majority of PC. Remember that if your PSU is too powerful, and if your actual consumption is too low, your PSU won't be very efficient.
Your average consumption should lie in the 20-50% range of PSU maximum power to get best efficiency.

5 out of 5 eggsGreat, but I miss my modular PS now =(

Pros: Plenty of sata power connectors and molex power connectors - 4 sata (just looked....picture does NOT represent that you actually have 4 satas!!!) and 2 molex (at least 2...didn't care that much). Powering my GIGABYTE GA-G31M-ES2L LGA 775 Intel G31 Micro ATX, Caviar Green WD6400AACS 640GB x2, Celeron 430 Conroe-L 1.8GHz LGA 775 35W Windows Home Server PC. Fit well in a non-PS case.

Cons: Not a modular PS. But I didn't buy for that. I just miss not having to worry about scraping wires and fumbling with other non-necessary leads. Bummer that the adjacent sata connectors on the same wire are so close together - drives must be next to each other to use them...not a biggie

Other Thoughts: Bought based on other reviews. Personally, I tend to buy dirt cheap cases that have great USB/audio placement with the best PS that I can afford. Very happy.

4 out of 5 eggsGood Power Supply

Pros: 1. Quiet.
2. Adequate power for most systems with integrated graphics or lower end GPU.

Cons: 1. 4 pin CPU power connector just barely reaches in my case with power supply located at bottom instead of usual top position. This is a microATX case. If it was an ATX case with PS at bottom, this connector would not reach.

Other Thoughts: I wish there were more high quality ATX power supplies available at lower wattages. Even 250 watts would be fine for me. I guess this is where the SFX size takes over.

5 out of 5 eggsGreat for low-end systems

Pros: Both 12v rails combined equal 23a, which is excellent for a 300w PSU and it powers everything in the computer silently; I can't hear it at all over the processor and intake fans. Exhaust temp is just warm under full load; see Other Thoughts for hardware installed.

Cons: No PCI-E power connector, but I already knew that when I bought it. This isn't really a con though, because someone buying a 300w PSU isn't going to be running a very high-end video card on it anyway. (8600GT doesn't need one)

Other Thoughts: Powering a Celeron D @ 2.93GHz, 2GB RAM, 1 SATA HDD, an intake fan, two DVD drives, and a GeForce 8400GS. Tested for 8 hours straight under load without any problems. Theoretically this PSU could power up to an 8600GT, which requires 23a on the 12v rail -- which is exactly how much this PSU has -- but I'd question how long it could last. If you're not sure if this PSU will be strong enough, you can always check using the eXtreme power calculator; just run a search for "eXtreme Power Supply Calculator Lite". Anything below 250w at full load -should- be fine.
