Couple stupid PC build questions.

[Peekae]

Hey looking to upgrade some stuff in the PC this year.

Running a decent but not overly pricy 500w psu and looking to uprgade my vid card / ram.



Im not looking to overclock the cpu or anything crazy but should i be worried when doing these upgrades. Just want to make sure i dont fry anything because the PSU wasn't up to par.




tldr: do i need to upgrade my PSU aswell when upgrading my video card / adding some higher ram sticks?

edit: This is the power supply I used in my budget build a few years back http://www.newegg.com/Product/Produc...D=rp3p89e0tuhp

editx2: Probably just going to upgrade the PSU aswell
