Quiet, 5 year warranty, efficient

Tech Level Tech Level: high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: I've had the best luck with SeaSonic power supplies and their new 80plus energy saving models are even better. This thing is virtually silent in normal use and improved my system efficiency about 10% over the power supply that came with the case. Not over rated (see below).
Cons: Doesn't have modular cables, but at this price, I wouldn't expect them. I'd rather they put the money in the internal components.
Other Thoughts: Most people buy a larger PS than they need and they waste energy. A 450 watt PS will use more energy running a 150 watt PC than a 330 watt PS will. The more lightly loaded a supply is, the *less* efficient it is. So don't buy one bigger than you really need. Few systems anymore besides extreme gaming rigs or servers with large disk arrays need more than 330 watts. My quad core system with 8 GB of ram, a high-end ATI video board, 2 hard drives, 2 optical drives maxes out at under 200 watts. Even the CPU/video card reviews back this up. It's rare any of their PC's draw more than 200 watts even at full load during benchmark testing and extreme gaming.

works great with the Antec P180 case

Tech Level Tech Level: somewhat high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: Works great in my Antec P180 case. Connected a legacy IDE hard drive, IDE optical drive, and the two case fans all with one cable. The SATA hard drive is on another.

5-year warranty card is included in the pkg. The SS web site has a picture.

Pkg. includes 4 screws and a y-adapter. Used one branch for a legacy floppy drive, which I tested and then disabled in my MB's BIOS.

The SS web site suggests that solid-state capacitors are used, but I didn't check.

Haven't had any noise problems, even though the fan is blowing air out the back.
Cons: While the 4-pin peripheral connectors have the easy swap feature, the SATA connectors do not, and they are not easy to remove. NB: do not squeeze the easy swap tabs while inserting, they are supposed to be squeezed when removing.

Cables are a bit too stiff to straighten easily. Not a real problem though.
Other Thoughts: Bought a SeaSonic Super Tornado 300 in 2003. It came with a fan that would not reliably start. The retailer (not NE) sent a replacement fan which I installed. In early 2004 the PSU would start and almost immediately shut down. SS handled the RMA very efficiently, and the replacement worked flawlessly from then on. Bought the new one as part of an upgrade that needed a more modern PSU (24-pin main power,SATA power).
