Question PSU power cord issue

[aadhiz]

Hi, Recently bought psu MAG 850GL from MSI and it comes with a power cord of 16A/250v. But I don't have a provision to plug the pin as it is very large. So plugged my older PSU cable i.e. mvme 650 from cooler master comes with 6A/240v.

Is it ok to use this for a longer time?
