(Graphics: Integrated in processor, AMD Radeon Vega 8 graphics)
(Storage: 1tb)

(Power Supply:Model l08261-002 180w 80 gold+)

        I intend to game on this computer, it runs lighter games but id really like to play heavier ones such as modern warfare. I attempted to do so already but my fps was only around 35. Is it possible to upgrade my power supply and do I need to do so for a stronger CPU with better integrated graphics / a decent enough external graphics card to run heavier games. Ive heard it was possible and not possible to upgrade my psu, i just need to figure out if i can, or if my current one can support some upgrades. Thanks!
