So I just bought a RX 580 MSI Armour edition after a few years of staying with a 730,and after I plugged it in the PCIe slot I noticed that I do not have an 8 pin connector but what I DO have are 2 4 pin molex connectors.After searching a bit on the internet I found that you can use an adaptor to convert 2 molex to one 8 pin but I just don't know how safe that is.Can it fry my MB or even the GPU or just the adaptor?My PSU came with the case(Spire CoolBox D201B 500W)
