Pros: I have been running this PSU since January 2007 (7-1/2 years) across three different computer builds. This PSU is as Rock-Solid reliable today as it was when I first installed it. What more can you ask from your PSU? This has led to the purchase of 4x more PSU from Corsair, and all of them are st...
Pros: I've had this power supply in continuous use for the past two and-a-half years powering my backup pc every time I've had to use it and it has been very stable. Never a crash or lockup due to "dirty" or unstable power, several due to unstable overclocks though (wrong settings, my fault). It is pre...
Cons: The only cons I can think of is that it only has two 6-pin PCI Express power cables, so no SLI or Crossfire with higher-power cards. Also, the PCI Express cables are a little short, so that could be a problem with bottom-mounted power supplies in large cases.
Summary: Love this unit only wish it was still being made.
Pros: This power supply has been my everyday unit for over 5 years. It just finally died and I was coming here to buy another one. There are a ton of modular connectors, and it has survived three motherboard upgrades for me.
Cons: It died, but after 5 years of almost always on use - I can live with that!
Summary: In 2011 I needed another 6 pin cable for my GTX460. Corsair customer support sent me a couple no charge. Several years after purchase and they give me a freebie, I'm now a Corsair customer for life. Excellent job Customer Service.
Pros: Still works fine and awesome customer service from Corsair!
Summary: When choosing between this power supply and ones sold by Seasonic under its own name, I'd ignore the name of the box and make my decision based on features and price.
Pros: I don't own this product, but another reviewer suggested that Corsair is better than Seasonic so I decided to post a review to let people know that this power supply is manufactured by Seasonic. That's a pro because Seasonic builds quality products.
Cons: The other reviewer reported getting several DOA Seasonic power supplies; obviously the same thing could happen with the 520HX since the manufacturer is the same. But I doubt that Seasonic ships very many DOA power supplies; the reviewer probably just had a run of bad luck.
Pros: Very quiet. Modular cables seem long enough for most mid-towers. Let it run for days on end because I had just returned a CORSAIR CMPSU-650TX that was defective out of the box (wouldn't POST). Ran flawlessly with little or no heat.
