The 7750 is actually very efficient. You should be fine unless you have lots of ssd, hdd, optical drives, pci-e, etc.
If you list everything hardware-wise, we can help you more.

Efficient or not using generic psu is not recommended let alone adding another 7750. 400w generic might be able to keep up with 1 7750 but idon't think it will if there is two inside. And from my personal experience my generic often break within a year. Worst case it will bring another component to the grave when it died.

@OP

if you really want to get another 7750 get at least 550-600w non generic psu
