Top Customer Reviews
What this means is that if you put in 3 PCI-e video cards that each draw 75W (through the socket) you will burn the plastic off the ATX connector around those sockets, and then your computer will randomly shut off. I called Corsair to discuss this and they at least said they'd look into it.
If you want to fix it yourself it's not too hard with less than $20 worth of parts from DigiKey. Feel free to comment/contact me if you want the part numbers. It's a a lot cheaper/easier to fix it before you burn the plastic off. (I also have pictures, if you want to see them, I don't think I can link them here. Look up my blog if you want to see.)
I'm still giving it five stars because I know this is really an edge case, but I think it's going to be more common soon. I'll also note I had this happen with a 1kW CoolerMaster PSU. Basically all consumer PSUs use cheap sockets there instead of Molex HCS sockets. Just to give you some idea how silly this is, those sockets cost ~0.50 each (needed: 2) when buying in single-item quantities. It drops to just a few cents apiece when buying in bulk (as Corsair would). How much does a velvet bag cost?
The power supply runs very cool, but I am only using about 25% of its power capacity right now. Unlike other reviewers who base their reviews on performance subjectively, I did test the power supply before I installed using a Coolmax power supply tester. Everything was tight!
While there are other power supplies out there that compete with this (like the newly released Antec HCP 1200 Unit, I chose the Corsair because they have always been about Quality and Performance for the enthusiast from their memory only days. This unit also comes with a 7 year warranty versus 5 for the Antec and other competeing units.
You can also get hold of Corsair by phone if you need to! They do not hide their phone number like other vendors all over the web.
While this power supply is probably overkill for most, if you are a Computer Enthusiast, Overclocker, and/or Multi-GPU Gamer, this is YOUR POWER SUPPLY. Well done Corsair! Superb...........
My 1 month update: I am so very pleased with this Corsair PSU. It's working great, there's no coil whine issue, and it's been a wonderful addition to my quiet-designed gaming pc. I'm using an Asus GTX 770 GPU and my system has all the clean and quiet power it needs.
