Hello, i need some help here, i wish someone could give me a little hand i would really appreciate it.... Im looking further to purchase a gtx 1660, but the gpu has a 8pin adapter, and my 500wat powersupply has only 6pin adapter. Now i have a little cable here that connects the 6pin to 8pin, https://www.amazon.com/JacobsParts-6-pin-8-pin-Express-Converter/dp/B00JLTCMFC , will i be able to use this cable to connect my psu with gpu without an issue because when i spoke to my computer mechanic he said that it will work just fine, not perfectly, but you wont have any problems, feel free to use it. Now you guys what do you think?
