Im buying a PC without gpu, and then gpu seperately. The PSU is 320W HP cfh0320ewwa, and it doesn't have 6 pin connector for gpu that I'm gonna buy, and that's Gigabyte Windforce GTX 1050 2gb GDDR5 OC. They said they'll include SATA Molex to 6pin, but I googled it and it sais it's very dangerous, but having 2 of those isn't. So should I get 2 molex to 6pin or I'll be fine with just that one? (gpu is using 75w)
