Will This Build Function?

[JoelTeegs]

I'm building a PC as cheap as possible for a friend, and I figure the cheapest way to go is to buy a used pc off ebay and add a cheap GPU such as an RX 460. I've found a PC for $100 with an i5-4570 and 8gb RAM, which is perfect, but it only has a 255W PSU. Thee RX 460 has a TDP of 75W and the CPU is 65W. Am I cutting it too close on the power supply, do I need a higher Watt supply, or should it be completely fine? Any input is appreciated!

Most power supplies of that low wattage aren't made to power dedicated graphics cards (even if they don't need additional power connectors). If you cannot supply a make and model number for me to look up, I can't guarantee that trying to power an RX 460 won't just be a fire hazard.

The GPU I'd add would be the
POWERCOLOR Red Dragon Radeon RX 460

Oh thank Gerd. When I saw PowerColor Red I thought you were looking at the Red Devil which is easily the worst card they've ever made. The Red Dragon is a good entry level card for medium-high at 1080p or high-ultra at 900p.

I still don't know what the make and model of your power supply is.

It's the PSU from the Dell optiplex 3020. It's sff

Now I must rant. Not that monstrosity again. Why do people buy slim towers? Okay I'm done.

You do realize that you'll need a slim graphics card, right? The one you've picked out does not come in a slim variant. I don't think any RX 4xx series graphics cards come in a slim variant because of how large the power delivery systems are.

Does it also take a slim power supply? If so, you're kinda screwed in terms of getting an affordable one that can handle high powered graphics cards without starting a fire.

Yeah that's kinda what I figured, the reason so many people get slim towers is because they're super cheap on eBay. It is a slim PSU as well, guess I'll just keep looking.
Also I've never gamed on anything less than 8 cores... So the question is, should I even consider building him a dual core machine, or should I stick with my gut instinct of quad core minimum?

PS. Do you have any suggestions for a PC I could get for $200 or less and add a GPU to? I want to keep the total cost as low as possible, so if need be I can throw my old 650 into one temporarily till he can buy a better card

If you're referring to FX 8xxx series and/or 9xxx series as "8-core CPUs", you're one of many that are terribly misinformed. https://www.youtube.com/watch?v=PgejkSWzvNs

Two Hyperthreaded cores (seen on i3's) are enough for all but the newest games, and four physical cores (seen on i5's) are good for just about all games. Intel stated in their 2012 architecture overview that each thread in a Hyperthreaded CPU can make independent forward progress. The key word is independent. This means that having two cores and four threads is somewhere between having two cores and having four cores. It's about the equivalent of four slightly weaker cores. I don't usually recommend i7's for gaming because there's no real need for eight threads unless you're going to be multitasking while gaming.

What's your budget for the machine as a whole?
