5 out of 5 eggsSimply Incredible

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 still humming a long just fine as well.

Cons: None what so ever.

5 out of 5 eggsVery stable power supply

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 pretty dead-on for voltage outputs. 12V rail puts out 12.02-12.03V under load, 5V rail is 4.96-4.98V, 3.3V rail is 3.38V. I tested it with my digital multimeter. The 3.3V rail is a little high, but still well within the ATX specifications. I will probably use it to power my next backup PC as well when I upgrade it to a newer platform, assuming it is still in good working order then.

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.

5 out of 5 eggsAWESOME

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!

Other Thoughts: Love this unit only wish it was still being made.

4 out of 5 eggsExpensive Replacement Cables

Pros: Energy efficiant and around two years and still working well.
Modular which is great for cable management.

Cons: My review is for those who are looking to replace missing cables. The cables are very expensive. I unfortunately lost most of my cables after I moved. The only cables I still have are the ones I used when I originally built my pc.

Contacted Corsair and they pointed me to their parts website. On the parts website every cable for this psu (6 Pin Pci-Express, 4 Pin Molex, and Sata cables) as of the date of this review is $7.99. $7.99 per cable does not include shipping and handling so factor that in and your paying well over that amount.

I needed to replace three cables for my system, but unfortunately 3 cables would cost me about $24 not including shipping. For that price it would be better to invest that money in a brand new power rather than purchasing replacement cables for an old one.

Great Power Supply, but if your modular cables ever get damaged or lost and you need to replace them your power supply becomes useless. It's almost as bad as having your Power supply die.

Your left with two choices either pay a high premium for replacement cables, or just buy a new power supply altogether. I would recommend the latter.

Other Thoughts: The unnamed reviewer before me was very lucky. He apparently received replacement cables at no charge. I was not so fortunate.

It is not Corsair's fault my cables are lost, but I wished they would make replacement cables more affordable because for the cost of replacement cables your better off investing that money in a new Power Supply rather than purchasing expensive cables for an old Power Supply.

5 out of 5 eggsStill Going Strong

Pros: Still works fine and awesome customer service from Corsair!

Cons: None, none at all.

Other Thoughts: 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.

2 out of 5 eggsLasted 3 years

Pros: Nice modular plugs. Handy storage bag for unused jumpers.

Cons: PSU died after 3 years in a ASUS (P4B533E) box. Computer exhibited strange behavior - Unpredictable shutdowns with increasing frequency.

Other Thoughts: Replaced with 600W OCZ 600SXS. Solved the problem immediately, and still working well after 2 months.

4 out of 5 eggsMove over Enermax

Pros: Reliable, power is smooth and accurate, run cool and quiet.

Cons: Still on the fence about the modular connectors but they seem to be working well so far. I think a different type of wire that is less rigid may be preferable.

Other Thoughts: Seems it would be hard to improve on these units. I have three of them that replaced Enermax units because I finally learned how important it is to have good rock solid power if you want a nice stable computer. I haven't had a single drive or motherboard failure since the transition. Imagine that.

5 out of 5 eggsMade by Seasonic

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.

Other Thoughts: 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.

5 out of 5 eggsDiehard Seasonic user converted.

Pros: Great quality, the box is even outstanding!
Really, just extremely nice build quality all around.
Again, seriously, the most well made piece of equipment Ive ever seen.

Cons: None

Other Thoughts: Used to be a diehard Seasonic user, but after several DOA S12s and S12IIs, I switched and never looked back
