I have a Seasonic 460w fanless psu that has a 80 plus platinum rating and currently have a i7-6700k and a gtx 1060 6gb. I was wondering if since i have a higher grade 460w power supply with a better efficiency rating could my psu handle an upgrade to a 1070 without upgrading my psu. I would upgrade it but it would cost an arm and a leg to get a 500w fanless psu. Also, just fyi, the reason i need a fanless is because every power supply i have ever gotten with a fan has nearly driven me crazy with the noise, i have extremely sensitive hearing you see, i even added a near silent after market cooler to my 1060 because the stock cooler it had sounded like i was sitting next to a jet engine. Thanks in advance for anyone who can help me.
