You can probably even contact Seasonic directly and order cables from them. They have super excellent customer service last time I had to contact them.
Heavy sigh. I did contact Seasonic, and they were helpful, but the news wasn't good. They still have cables available for the SS-650KM3, but I have the older SS-650KM, and not only do they not have cables for it, they told me that the pinouts are different for the KM3. So now I'm left wondering if the Ebay cables for Seasonic power supplies will even work on this particular Seasonic? As someone once quipped "The wonderful thing about standards is that there are so many of them!"
I tried to use this PSU to test a motherboard yesterday, but the only CPU power cable I have for it is an eight pin to eight pin, and the motherboard's socket is the more usual four pin, so it wouldn't work. I then swapped in a SilverStone power supply that had the four pin CPU power cable, but no graphics card power cable. This was initially fine because I was going to use a graphics card with no external power, only it turned out that the motherboard (Asus M2N-SLI Deluxe) didn't like two of the three graphics cards I have that don't use external power, presumably because the power draw was more than the slot could provide, and it wouldn't POST, just give one long beep and three short beeps. I want to test it with my GTS250, so I'll have to swap to yet another power supply.
