Alright, well anyway. lol
Neither. They both only have 2 x 6+2-pin PCI-E connectors while all other good 650W PSUs on the market have 4. Why? I don't know. Corsair is stupid these days. The PSUs that Corsair used to make these two units have 4, so why didn't Corsair keep it that way? Y'know?
Another problem is, Corsair PSUs are usually overpriced for what you get. You can usually find a better one for about the same price, or an equal one for less.
What store(s) can you order from? Can you link us to the Power Supplies department of the store(s) you can order from?
Also, how much can you spend on the PSU?
Actually In India, Antec and Seasonic are overpriced. They are way much more expensive than corsair and take a long time to RMA. That's why i prefer corsair.
