I have the pre-built Dell Inspiron 3656. It had an AMD Radeon R9 360 which I replaced with a Geforce GTX 1050 OC 2gb Windforce by Gigabyte. Only issue is that my PSU is 100 or200w. Amazon said GPU needs at least 300. But I dont know much about my pre-built pc so I dont know what PSU would fit and if I need adapters. Im looking for 3656 adapters if any are necessary because all there is I could find was 3650. Any help is appreciated.
