my pc is transported a long way to our province and when I turn on the pc no signal from gpu, but when I unplug and plug on motherboard vga it has signal. I am using a non true rated psu and 1 sata to 8 pin I suggest the 1 sata to 8 pin is broken? or graphics card? the motherboard pcie x16 is good as I say because I plugged my g210 on my pcie and installed drivers fine pls i need answers

A.should I replace sata to 8 pin with SATA Y to 8 pin?
B.should I replace power supply with true rated bronze 80+?
C.what do u suggest better?

Cheap, rubbish PSU so that's very likely causing the problem. It has no business being used on a PC which is equipped with a gaming card.

You need to replace it with a 500w recognised reliable brand like Seasonic, Corsair or EVGA.

Make sure new PSU has the required number of 8-pin and 6-pin GPU cables that your GPU needs.
Using any type of adapter cables for these is bad practice.

When a PSU doesn't have an 8-pin GPU cable it means it's not safe to use it with an 8-pin GPU.
