Mmhh, on YouTube Australia it is stated that only the 1350W and 1650W GF3 comes with an 600W 12VHPWR cable. And the 1200W and 1000W GF3 with an 450W 12VHPWR cable. Is that really true? I'm asking because I ordered the 1200W GF3 with the strong belief it can deliver 600W for PCIe 5.0 graphics cards - as stated on the product page.
