SeaSonic SS-300ET Bronze 300 W ATX12V V2.3 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Significant power savings over typical/older power supplies. Using a Kill A Watt device, I measured my system at ~147W. I was using a Sparkle PSU that's about two years old. After switching to the SS-300ET, the power dropped to ~110W. My system is on 24/7, so I figure the 37W savings will net about $35-$40 a year in power cost reduction. That'll just about pay back the cost (ROI) in one year. Highly recommended.

Cons: Caps are "Su'scon" brand. Websites and discussions of the dreaded "Capacitor Plague" (early capacitor failures common in motherboards and power supplies) indicate this brand has had problems in the past. Only time will tell if the SS-300ET will suffer from capacitor failures too. I would have preferred to find top-quality capacitors inside.

Overall Review: High quality ADDA 120mm ball-bearing fan (AD1212MB-A71GL) is whisper quiet and I'd expect it to have a very long and reliable lifespan. This PSU is only 300W, but this is sufficient for many systems, and power efficiency is often better using a properly sized PSU. If you wonder how much power your system actually uses, get a "Kill A Watt" device (available on NewEgg and surprisingly inexpensive, in my opinion) and find out.

Pros: Good brand

Cons: May be unsuitable for bottom-mounted cases

Overall Review: The primary power cable barely reaches an LGA775 motherboard in a HAF 912, the 12V will not reach with any cards installed. Which is a shame, as this would have been a good match for a low-power FreeNAS system.
