Great PSU, cheap 12V sockets on the ATX connector
on May 31, 2011
This is a great power supply. I'm abusing it with bitcoin mining 24/7. They throw in a lot of fancy stuff, velvet bag, etc, but cheap out on the 12V sockets on the ATX connector. They're only rated for 6A or so and it's easy to pull more than that.
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?
