Alright so I have to upgrade my PSU first. Oh, and one more thing from what I read people also where saying that my motherboard wasn't compatible with UEFI or something like that. Are both these GPU's okay if that is the case?
UEFI is just a new version of BIOS and GPU doesn't care at all if you have Win 7 installed in MBR mode (Legacy) or GPT mode (UEFI). It doesn't even care if you have MacOS X running in APM mode (EFI-CSM).
Also, as readable from gamerproject1998 reply, which he has now conveniently deleted, a claim of "GUI interface bios, smart fan control and other things" are not part of the UEFI. They are readily available on any modern MoBo, regardless if BIOS is older (Legacy) or newer (UEFI). E.g my MSI Z170A Gaming M5 MoBo, running Legacy BIOS has GUI BIOS and SMART fan control, among other things.
For a new PSU, i suggest getting any Seasonic unit, in 500W range. E.g: Focus 550, Focus+ 550, PRIME Ultra 550 Gold or PRIME Ultra 550 Platinum,

Warranty wise:
Focus: 7 years
Focus+: 10 years
PRIME: 12 years (includes all PRIME models: regular, Fanless, AirTouch, SnowSilent, Ultra)
All 3 of my PCs: Skylake, Haswell and AMD are also powered by Seasonic. Full specs with pics in my sig.
He has a good point almost missed that,
this is perfect. Not a 550w but 600w for future proofing. It is pretty cheap too and high quality.
So, you went on amazon, put into search bar "500w power supply" and gave the very 1st PSU link here, really?
😱 Not only that but you also messed up in claims of it being 600W unit while the link you gave clearly links to a 500W unit.
Also, you don't know nothing about PSUs if you're suggesting that Tt Smart series PSU as "high quality" unit. Do you even know who the OEM of that PSU is? Ever read any reputable PSU reviews?
That PSU which you're suggesting is low quality unit and while it may be perfect for you, it is in no way perfect for anybody else.
