Pros: This is my third Seasonic. I'd have bought more, but I only have three computer systems. Now each of them has a relatively efficient and quiet ps.
Cons: I don't know of any. The cables are more than long enough for all my ATX towers with the ps mounted at the top. I trust Seasonic more than any other brand on the market.
Overall Review: I don't even look at other brands. They are not competitive in the 300 W category, which Seasonic dominates with Bronze ps. I bought the Seasonics to replace inefficient and in some cases noisy power supplies, and I'm pleased with the results. Knocking 60W from a 24hr system results in very real savings to the bottom line. I don't know why people ever purchase ps rated above 300 W when 300 W is overkill for 99.9% of all computer needs. I think it is just a size contest with ppl thinking a larger ps equates to more power--actually more waste. The trend is for less power consumption, not more.
