👍just making sure it wont exceed wattage
It will be close to the max capacity. This means extra stress on the PSU, high draw at the wall socket and possibly more noise.
But yeah, it will work. And of course, it will not draw a lot of power all the time, only under load.
It's better to have extra wattage and greater efficiency because it means the PSU works closer to optimum and you pay less for electricity.
But you didn't ask if the MAG would work closer to optimum or save electricity.

So the answer is yeah, it will work.
Don't be surprised by occassional spikes in power draw from your GPU. Power hungry cards can suddenly demand a lot of power. Happens in a split second but has been known to cause problems.
This is why beefier and higher quality PSUs are recommended.
