Razer Blade 14 late 2016 power supply

[Gahu]

Hey Guys, 

I think that my power supply is dying (Razer blade 165W) cause my laptop is discharging quite quickly under load when the charger is plugged in (3 hours of BFV, never happened before)

A replacement charger is 150 € here in europe (So ... a total rip-off basically) and I'm looking into "3rd party" alternative. 

 

There is one charger from Delta Electronics (Used for MSI and Clevo Laptop) that was adviced by people online.
However, the output Voltage is slightly different (19.5 instead of 19.8 V) and the wattage is also different (180 W instead of 165 W) 

As far as I know, the wattage should not affect the laptop (correct me if I'm wrong) as it should only draw as much power as it needs. it might even help as the 165W power supply is quite weak for the configuration. 
But would the slight difference in voltage be an issue?

Well, wattage is voltage times amperage, so you'd be putting more amps into your laptop. It may be fine, it may not be.
