i'm looking to buy used and i know it's not the best option but it's the only option so if anyone knows any tips about buying used graphics card that would be incredible.

I'm thinking of buying a graphics card.And i would like to buy rx 480 but now i have some questions there is a RX 480 Sapphire NITRO + 4gb and Radeon RX 480 8GB GDDR5 256bit I would like to use it for gaming are there any major differences between the 4gb one and 8gb one,on the picture 8gb one has only one fan so i'm quite a newbe when it comes to pc graphics etc.So if anyone can tell me if it is better to get the 4gb one with 2 fans or is the 8gb one okay?

RS-460-PSAP-J3 or Combat Power 550W CP550 anything?

i found Chieftec 400-80p would that be okay?Insert other media

BQT-E5-400W or LC6450 V2.2 or Tech Solo TP-450 rev. B ATX 2.3 is any of these good enough?

would something like Rasurbo DLP-435 get work done?

The country is serbia and the budget is 20 to 30 buck but i don't have a problem with buying used power supply

So i would like to to combine an old optiplex 990 with i7 2600 with 8 gb ram and a sata hard disk and i would like to buy a gpu like rx480 or rx580 so i need help when it comes to the power needed for my pc.What power supply would be good for it and if i can say is there a power supply that will be just enough for all of that because i don't have a big budget for a power supply. Thank you everyone.
