hello,
so I have been wanting to buy an hp z420 workstation for gaming and productivity and i wanted to put in such specs
xeon e5 1620 vs (it is a bit old but it is great for my budget)
ram 16gb
1tb hard drive
128gb ssd (for the os)
and a radeon rx 580 nitro+ 8gb
problem is i have seen many people upgrade their power supplies to fit their graphic card needs so my graphic card requires 300 watts of power and the system i want to buy has 600w power supply but no 8 pin connector so do i need another power supply for it or can i make it all work, also keeping it in perspective that the rx 580 needs an 8 pin gpu power connector so can I come by all these problems by using a 2x sata to 8 pin connector and have it all work fine or do i need another power supply for it, and if i do what is the one which will fit and also give suffiecient power since i do plan on upgrading it to a gtx 1080
