Do I need to upgrade my power supply?

[BillyG180]

I am looking to upgrade my graphics card from a gtx 750 4gb to a 1050 or higher. Also add a second hard drive. My computer has a 300watt power supply. Would I need a larger power supply to do my upgrades and if so where would be the best to buy the power supply?

You could count up all the poweruseage and see how much power your current PSU delivers (300 watt is probably not what it gives, but what it pulls from the powernetwork aka "the wall"

There probably are a few programms out on the internet that can make the calculation for you.

Did a Google for you, that should do the trick.
If you don't know your current specs, download speccy, its a free tool delivered by cc-cleaner.

Fill in the current items and what you want to upgrade your pc with. Let it make your calculation and you have your answer

For me it calcualted a 500 PSU, i'm using a 650 watt one, so i got a little overkil xD

Thanks for the help. Speccy really helped me fill in the calculator, i tried before but didnt know little details. If you want to know further in my build I am having to upgrade psu for graphics. Thanks again for the help!
