Need guidance on purchasing a new system
Need guidance on purchasing a new system
Hello
I’ve finally secured enough savings to purchase a new system.
Could you let me know if this setup is reliable enough to last several years?
The components include:
CASE – Corsair 5000D Airflow RGB QX Edt. | schwarz
CPU – Intel Core i9-14900K, 8x 3.20GHz + 16x 2.20GHz, 36MB L3-Cache, water cooler
Mainboard – MSI MPG Z790 Carbon WIFI DDR5 | Intel Z790
GPU – MSI 4090 Trio RTX
RAM – 64GB DDR5-6000 Corsair Vengeance RGB, 2x 32GB
Thank you
A solid high-end construction. Choose the cheapest RAM possible, ideally over 6400. Your power supply will play a significant role in this configuration. What units were you considering?
For gaming purposes, consider models like the 7800x3D, 9800x3D, or 9700X to see how the 14900K consumes a lot of heat. Remember that the RTX 5090 and 5080 will be available in January.
Is this a ready-made setup or a collection of components you need to put together?
What is the model number of the PSU?
No matter, these parts offer the top gaming performance available right now.
Don’t worry about 13/14gen fud problems—those are outdated issues that have already been resolved.
Make sure the motherboard BIOS is up to date.
I would prefer the 7800x3d rather than the 9800x3d. The reasoning is that if you're using a 4090, you won't be in 1080p, and most benchmarks show that once you go beyond 1440p and 4k, the improvements are minimal—often just a few frames per second gains or barely noticeable at all in higher resolutions.
Avoid Intel; AMD AM5 sockets are believed to still support ZEN 6, which means compatibility with the 7000 series, 9000 series, and possibly the 10000 series (though I’m not sure what that name is). This should significantly extend the lifespan of your system.
A 2x16GB RAM CL 30 6000 is ideal—it's a perfect balance and more than sufficient for gaming. (Skill RAM is among the best, and I’ve used it extensively.)
Consider getting the X670e to save money compared to the 870 boards, while still offering a few extra features that aren’t game-changing.
Asus ROG boards have worked well for me, and I have a preference for the MSI Tomahawk series boards. My MAG X570 Tomahawk Wi-Fi board performed exceptionally well!
PSU is something I’m particularly interested in now, as I’ve rebuilt many PCs before (just updated my main and photos in a members thread). A 1000W PSU is fine for the 4090; I usually overkill with 1000W Platinum models. My current setup uses a 1000W PSU, but next year I plan to switch to an AMD board, which will make me think about the right wattage.
I’ve been using 1000W PSUs for several years without any issues.
My reasoning (even if it seems odd to some) is that the Seasonic Prime 2200 (around $1000) is way too much—its 12-year warranty and 80 Plus Platinum rating make it a long-term investment. It will likely be the last PSU I need for a long time!
However, with the 5090, you might want to upgrade or wait. I’d recommend something over 1000W Platinum, 1300W, or even 1500W at the very least.
I’ve tried both Corsair and Asus PSUs, and both have performed well—especially my Corsair models, which I highly recommend.
The Arctic Freezer II or III still offer the best value for performance, and with the Arctic Freezer III it looks even better. It’s not a fancy LCD setup, but it delivers solid performance and looks great.
I’m not 100% certain about all Corsairs models, but the most common RM750W to the HX 1000 watt PSUs with 80 gold to 80 platinum options are reliable!
Having used them repeatedly in various builds without any problems has been my experience.
Many (not all) issues linked to PSU problems begin with the fact that I’m constructing a 14900k with a 4090 and I need a budget-friendly PSU just enough wattage since I’ve already spent most of my budget on components, not the PC’s core.
Or simply not grasping power spikes or other factors that can lead to issues when using a low wattage PSU.
Lemons are part of any company—I’m not claiming all Corsair PSUs (expensive or not) are perfect—but based on my experience, a decent PSU is less likely to fail!
I definitely don’t recommend buying a 2200W PSU for a low-end PC, but just be sensible!
most problems with power supplies stem from low-quality manufacturing that causes the rated wattage to fall short of actual performance, faulty protections, and premature failure due to early wear. this issue is especially common when people purchase units with insufficient wattage. indeed, nearly every company offers lower-tier models that are unsuitable for gaming or other demanding systems. it's not just isolated failures; entire batches often share the same defects and risks. the exact model and production year significantly influence these problems.
