Hello

i am looking to build my first PC

the components i have currently looked into; please let me know if these should work or what i should change; thanks in advance

CPU - i9 12900K

MB - ASUS ROG Strix Z690-A Gaming WiFi D4 LGA 1700

RAM - Kingston Fury Beast (Black) 64GB (2x32GB) DDR4 3200Mhz CL18 Dual Channel Memory Kit x2 - or is 3600Mhz more desirable?

GPU - not going to game - will want to run at least 2 displays or the samsung 49" DQHD display - will the CPU and MB suffice or should i get a GPU, and if so which one?

PSU - Corsair modular - min 850W is okay or shoild i opt for more?

CPU cooler - Corsair 360mm AIO

Case - Corsair 200T or XTIA Xproto ATX - looking into small footprint ATX cases - any and all suggestions are highly appreciated

Storage - i have SSD from current PC

so everyone, please let me know if this build is okay or if i should change any component or add any.. thanks in advance!!

What is your usage that you think you need a 12900k? The 12700k is a more sensible choice. If you never intend to install a GPU, then 850w is overkill, but at least it should allow for quiet operation. Since you are doing corsair case, and AIO, I would stick with Corsair for the ram too, so you can easily control the RGB with icue.

haha last time i needed a computer (2013), i wanted a mac, but money was tight so my dad built me a 3770K for less than half the price including a monitor, its still blazing fast with an SSD, but ive pawned it off to my sibling.

long story short, i want to invest in something that will take me another 10 years ish. currently using a lenovo i5-4570.
i dont intend to use RGB at all. i am in the medical profession so i might use some medical related software down the road (hence multi display or just rather an ultra wide screen) but other than that i just dont want it to get old quickly.

i was thinking about the NZXT h1 but idk how a 140 AIO would handle the 12900K.. or if going for 2 ram slots would be cost effective since i'd have to dish out more for 64gb single sticks.

would not having a GPU still run the 49" ??

If you want it to be as quiet as possible, consider adding Noctua case fans.



AMD Radeon Pro WX 3200 is the cheapest card to get loads of displays.

Has a TDP of 65w, will run fine on this PSU listed.

YOu don't need 64 GB of RAM....

Save your money. Get 32 GB (16 GB x 2)...it's still plenty of RAM!
i was thinking about 128gb actually, just maxing it out and not worry for another 4-5 years at least. im not that tech savvy when it comes to PC, my 3770K was running perfectly fine. if i cant make a decision or if my end budget is not upto my liking, ill take back the 3770K from my sibling LOL

It's taken the pc world 40+ years to go from @ 5k of ram to an OS that runs just fine on 8Gb. For non production, non gaming, non content creation and non VM use, you'll have no need of anything more than 16Gb for the foreseeable future. In 10 years your pc then will be not too much different than your 3770k is now.

High ram amounts like 64/128Gb are actually a detriment to pcs as they must by nature slow the memory controller or it overheats from the speeds and voltages required by higher speed ram. You'll generally find server class mobo's and cpus running 2133/2666MHz ddr4, not 3200MHz + when running 128Gb of ram.

In layman's terms, what you are asking to build is a Lamborghini to get the mail at the end of your driveway. There's nothing saying you can't, or shouldn't, it just seems pointless to run a 12900k with 128Gb of high speed ram for websurfing, just in case.

You'd be far better off spending half the price for something decent, and in 5 years spending the other half on a replacement. At 10 years from now you'd still have a faster pc than overspending on future proofing today.

what would half the price get me anyway?

For non production, non gaming, non content creation and non VM use, i might as well keep the 3770K and just overclock it with a better cooler.. i could get that done within 100 bucks

I'd think something along this line would suffice. Uses less power and creates far less heat.

I played video games on 16GB RAM for over 5 years. Only game that ever gave me trouble was Anno 1800 with all DLCs enabled. I doubt there are many use cases even gor you to need excessive amounts of RAM like this.

Also, if you never intend to game or being productive on this machine, even a 12600, 12400, or, heck, a 12100 would probably be fine unless you want to program or run something that needs loads of cores/have many, many programs running at the same time. And yes, I mean for the next couple years. I expect my own 12700k to be enough for gaming for the next 8+ years considering my track record in this regard, and know what? My old system is still active, it was brought to my parents and is running there ever since I got the new one, no issues, nothing. I5-7600k with 16GB RAM, should run until this one is getting retired (hopefully; if not, I have backups) since load is so much less there. Computers can last you a long time if you don't game. I could probs start my old 3670k system up and it would still be running fine...

With a decent cooler like NH-D15 or 280mm AIO and a little luck from the silicon lottery gods, there's no reason why you can't push a 3770k to 4.8/4.9GHz and keep it in the 1.3v range. You'd not want to be close to 1.4v vcore.

That's if using the gpu to encode the stream using Nvenc.

If using X264/OBS, then I'd say a 12400/12600k is going to get you a better picture, much higher single thread performance, and better hardware acceleration and IPC.

FYI, Epyc, and Threadripper pro, use 3200 natively. 64gb ram is ok, for longevity. I wouldn't do 128gb though. I have 128gb on my work machine, and don't think I really use much of it, on my inspection software that deals with CAD models. I do still say 12700k is the better choice. Those 4 extra E cores, of the 12900k, are not worth an extra $200+. That $200 is better spent elsewhere, like really nice/fast storage. If you absolutely want the extra E cores, then just go with a non K 12900, with a nice B660 board.

Hey! I bought an asus Tuf z690 DDR4 motherboard and I had nothing but problems. I changed it to the Asus ROG z690 Gaming F with16GBx2 =32 GB of RAM (Corsair Vengeance 5600MHz DDR5) And HERE came the actual improvements feeling wise and speed wise and general stability. I love DDR5! Just dont buy x4 of em cause they wont speed up but buy 2 sticks of RAM and the speed upgrade is just awsome compared to ddr4 (3600 MHz corsair Vengeance btw). I bought the i9-12900K but I regret that since the 12700 or even the 12600K gives 90+ ish % of the speed anyway but double the price. Use win 11 btw. Fresh install!! Everything just works after I did a fresh install on win 11! Perfectly! Even games that stuttered before just dont anymore. Elden ring doesnt even drop a single frame!! And just general use is absolutely great tbh and very very fast whatever you do. That's my recommendation having owned both the z690 DDR4 version and now a DDR5 version :D Good luck!

The biggest issue to date with DDR5 was its timings. Ram isn't a single thing, it's a whole bunch of things in one. If you think of ram timings like going through a house, you'd be in the ballpark of general idea.

You got 5 primary timings. Think of it as the time waiting on the garage door to open, go through the house, open the front door and go out. The MHz is the speed of your feet. The 40ish Secondary timings include the length of the stride, the time to open the kitchen door, time to go through that door etc. So if your feet move at 5600MHz but it takes 32 strides to cross the room, that's actually slower than ram at 3600MHz that takes 16 strides to cross the room.

Faster ram doesn't mean much if the timings are so large they negate the speed advantage, data just takes forever to get through the ram. It's why 3200MHz/14 Cas is basically the same as 3600MHz/16 Cas, one ram takes longer strides at a slower pace, the other ram is a Geisha moving fast feet in shorter strides, both taking about the same amount of time to cover the distance from in to out.

This has happened with every single DDR release, the initial period is a crying shame, in some cases the older ram being measurably faster overall than the newer. DDR3 2133 had timings of like 12-13-13-32. DDR4 2133 had 16-16-16-48. Considerably slower overall.

It's only when DDR matures, speeds increase and timings come down, that speed advantages mean performance increases.

Intel worked very closely with Microsoft to develop the scheduling necessary to take advantage of p/e cores relationships for Alder lake cpus in Win11. That same tech is available in Win10, since Win11 is just a tweaked version of Win10 code with some minor design changes. It's just not activated in Win10 on purpose, that was Microsoft's stipulation, they want to promote the new OS, not support the old OS. So to take real advantage of 12th gen, you'll want Win11, but for the most part, they are pretty much the same.
