[SOLVED] ZOTAC GeForce RTX 3070 Ti 8GB AMP Extreme Holo

Im looking into buying the above GPU. I have a Seasonic Focus GX-750 PSU and think I might have a problem. The GPU needs 2x8 pin and 1x6 pin to power it but the PSU only comes with 2x8 (6+2) PCIe pin cables. Where can I buy the extra cable for this PSU? (im in the UK)
