Hi guys, this is my first time incursioning in multi-GPU setup territory. I'm about to build a rig with 2x GTX 650 Ti Boost and an i5 Haswell not unlocked -not going to OC it. To don't go deep into details about the rest of the hardware, my question is if this PSU is enough for what I'm intending even if it isn't certified for SLI or Crossfire (bottom section, look for the right model) but has 2 PCIe 6-pin cables; I live in Mexico so my buying options may differ a bit and the price point. I find this PSU decently priced but if you consider it is not enough I have room for a CoolerMaster 700W PSU that costs the equivalent of USD $15 more; I would prefer to save that money, but if there's no true use for the 600W option I'll go for it. It would be preferred if you have arguments based on personal experience.
