Using 4-pin molex to 6-pin connector on a psu with no 6-pin connectors

[CaramelApples]

So I have this cheap 600w power supply that doesnt have any 6 pin connectors. Is it safe to use 4-pin to 6-pin connectors to power a HD 7850? I know that i should probably get a better power supply but Im kinda low on funds (college student). Heres a picture of the side of the said power supply. Thank you in advance!

No, it is not safe. You can't push 75 watts through one of those without severe risks.
