What Wattage Power supply do I need?

[Thiccboy]

These are the parts of my build that I bought:

 

• MSI b450 tomahawk max
• Gigabyte rx 5700 xt 8 GB
• Ryzen 5 3600
• 2x8 gb 3600 MHz RGB ram (because I'm an epic gamer, deal with it). This will probably need 1000W of power itself due to its epicness.
• wd blue 500 gb nvme ssd

 

So how much power does this system need? One build I saw uses 600W, while the manual for the gpu says 650W. A quick google search says 550W. I want to be on the safe side here, which power supply should I get? I don't want to waste any extra money buy buying more power than I need, but also don't want the bare minimum. Thanks for the help.

A good quality 550-650watt should be fine.

Like, EVGA G+, Corsair TMx.

You'd be okay with a 500W PSU. Just make sure you get a quality one. Check the tier list in my signature.

Is a Thermaltake Smart RGB 600W PSU SPR-0600NHSAW fine?

Or a Thermaltake Smart RGB 500W Power Supply SPR-0500NHSAW

I'd highly recommend going for something higher rated, shoot for 80+ Gold or better. 80+ White is the lowest possible rating on a power supply

It's not even on the list, so no.

I'd go with something better than a 80+ White. I'd much rather buy a 80+ Silver or Gold. If you can find a 80+ Platinum on sale for cheap and it fits your description needs buy it.

These are the only 2 psu's in my area. Will using these put my components at risk? Is it worth it to buy one of the psu's in your list?

Potentially use online shopping?

Lower quality PSUs have worse voltage regulation and less safety.

 

Worse voltage regulation realistically means your parts will still run fine at stock speeds, but they might be less stable when overclocking. (you will get a lower maximum clockspeed before the computer starts crashing)

Worse safety means that there is a higher chance of the PSU failing. It's still a small chance, but higher than the more reliable models. IF the PSU fails, it might take other components with it (sometimes lower-quality power supplies deliver a huge voltage spike while they're dying, which could kill your GPU, Motherboard, or even CPU/RAM). This is all IF the power supply fails. You could use it for 10 years without issue, or it could explode within the first month. You'll probably be fine though, even lower quality units don't catastrophically fail too often.

 

Another thing to consider is that 80+ White power supplies are not as efficient as higher-rated power supplies. If you're running your computer 24/7 or plan to run it at high loads often, you might actually save money in the long run by buying a more efficient PSU.

Wow, thanks for the detailed response. Damn, I wish I knew this earlier. Truth is, I'm currently living in a third world country. My brother is coming this Sunday from Canada with all the parts I listed earlier. I just figured that I could buy the psu from here, without realising it's importance. The only 2 decent psu's I could find (online) are the ones I sent you. I guess I'll just have to risk the life of my components.

 

As for efficiency, I'm not really too worried about that. How much electricity I use isn't a problem for me, it's just my shiny brand-new parts I care about.

If it's any consolation, the PSU will 99% chance be totally fine and you won't notice a difference between the thermaltake and a higher-end one. The reason people advise getting a better PSU is for the 1% chance.

I like those odds. Thanks for the help.
