Re: Best pc for the sims 4 with the highest settings A LOT OF MODS & expansi

@Maisha7197  No worries about the links; I just didn't want to show you what I thought you should get, instead of finding out what you wanted.

You're right that people tend to make some critical mistakes when trying to save money on a custom build.  One common bad shortcut to take is with the power supply—you want to make sure it will comfortably run all your hardware.  I picked a 650W Corsair, which is a PSU with more than enough power and made by one of the best in that category.

Another important detail is the motherboard, and there are a few decent options on the list.  If you want to talk specs, let me know, but the short answer is that the Asus selected and the cheapest MSI (the Z390-A Pro) both have minor drawbacks, but not necessarily anything you'd notice if you weren't planning to upgrade yourself.  The next one up (MSI MPG Gaming Plus) doesn't have those drawbacks.  Still, any Z390 board from a reputable company is going to be at least good enough for what you want to do with it.

Also, be sure not to get a case with a top-mounted power supply.  It looks like most of them mount the PSU at the bottom, with the exception of the In-Win models.  But sorting through cases gives me a headache, so list a couple that you like and that aren't too expensive, and I'll look them over.  (Otherwise, the list is very long.)

I went with 16 GB RAM, so you can always multitask, and I upgraded to 3200 MHz because who doesn't love fast RAM?  (It's certainly a great way to spend £7.)  I also added a wifi adapter, since I have no idea what your setup is going to be.  And I chose a good air cooler because your processor doesn't need liquid cooling.  If you want it though, go with the Corsair H60 for £10 more.

With the other parts, they're all fine for your purposes, but the next upgrade up may or may not be worth it to you.

• The Intel i5-9400F processor is more than strong enough for Sims 4.  The next two upgrades up cost £50 and £91 before VAT for a small and medium-sized improvement, respectively.  I don't think they're necessarily worth it.
• For the graphics card, an AMD Radeon RX 590 is only £18 more than a 580, which is a good investment.  The next card up would be the Nvidia 1660, for £15 more, but the performance benchmarks for the two are equal overall.  (Which is the better card depends on the game; both are more than fine for Sims 4.)  I don't think you need this "upgrade" unless you really want an Nvidia card.
• I didn't change the default hard drives, which are a very fast 500 GB solid state drive and a very large (and somewhat slow) 2 TB mechanical drive.  That's more storage than you'd probably ever need; you could switch the second to a 1 TB HDD and not miss the space.  If you want an even faster SSD, an upgrade to a better 500 GB model would be £12.  You would probably never notice the difference, but some people like to have the fastest option out there.
• Also, if you'd rather just go with SSDs, that's a viable option, if more expensive.  The first thing to figure out though is how much storage you want.

That covers all the internal components.  Windows 10 is also included.  As for accessories, don't bother unless you already know that you want something and it's cheaper on this site than the other places you were looking.  It's probably not though; one way sites like this make their money is by marking up the add-ons.

And of course, feel free to keep asking questions.
