Power Supply Power 3070ti from one pcie 8-pin and dual sata to 8pin

[zain]

I am using a 3070ti with a single 8-pin split to dual 8-pins cable , so in total it's getting 225W , including the 75W from the pcie slot, but under heavy load it needs around 280W , so I was thinking that instead of splitting one 8-pin (150W) cable to dual 8-pin I should use maybe a dual SATA to 8-pin adapter to fullfil the need of extra ~70W. Can someone guide me if that will be ok ? Currently I have limit of 225W on my GPU , I'm using a 685W psu dell proprietary comes in t5810.
