Nvidia's RTX 4090 is a behemoth of a GPU that can do much more than just max out modern games. It has uses that can vary across the board, which makes it a challenging addition to most PCs. After all, the RTX 4090 requires a beefy PSU, plenty of airflow, and a capable CPU to eke out its potential performance at full throttle.

Update, June 22nd, 2024, by Rahim Amir: The builds below have been updated to reflect a recent drop in RTX 4090 and current-generation motherboard and CPU prices even as the 14900KS is now in play for Intel users. This has allowed the team to reallocate some of the budget towards newer or higher-end PCI-E 5.0 SSD storage options, as well as better PSUs and cases where possible, even as the PC build market leverages better availability of the RTX 4090's various AIB options.

Why Should Users Consider Different RTX 4090 Builds Based On Their Needs?

The requirements for gamers, enthusiasts, and professionals can vary based on their needs. Gamers would ideally want to pair it with the highest-end gaming-centric CPU money can buy. At the same time, productivity-based users might take a more nuanced, multi-threading performance-centric approach. On the other hand, enthusiasts might want the fastest all-round PC that offers plenty of expansion, upgradability, and overclocking potential out of the box.

This means that RTX 4090-based PCs can not be a one-size-fits-all solution that performs best for gamers, creators, and professionals alike (but some builds come very close). Therefore, the team at Game ZXC has handpicked three different gaming PC builds that feature an RTX 4090 to eke out the highest possible performance from Nvidia's flagship GPU in 2024.

  • Lian Li O11 Dynamic EVO XL pc case
    Lian Li O11 Dynamic EVO XL

    The Lian Li O11 Dynamic EVO XL is a full-tower all-white PC case with a smart design. The case allows users to reverse the chassis, meaning the tempered glass will face the right way if the PC is kept on either the left or right side of the setup. There is integrated RGB lighting and a seamless tempered glass side that flows almost seamlessly into the front panel. The Lian Li O11 Dynamic EVO XL can accommodate up to a 420mm radiator next to the motherboard and the same at the top or front using the included bracket. A full-sized GPU that's up to 450mm can also be used in this case.

For gamers looking to max out the performance of Nvidia's RTX 4090 for gaming, one can't go wrong with the gaming king of the hill, AMD's 8-core, 16-thread Ryzen 7 7800X3D. The octa-core CPU offers significant performance gains in games versus both higher-end AMD and Intel counterparts, retaining its performance crown well into 2024.

This is paired with a well-priced 32GB kit of handpicked low latency G.Skill memory on offer that can leverage the sweet spot for AMD's Ryzen 7000 series CPUs at 6000 MHz. This is despite AMD's X3D CPUs being less demanding in terms of RAM speeds due to their larger L3 caches in play. Users can upgrade to 64GB of total RAM by adding 2 of the same kit or by opting for a 64GB kit of the same option with further room to upgrade down the line.

The ASRock Taichi Carrara X670E is the centerpiece of the build, as it pushes an all-white look backed by its marble-themed design and even offers excellent VRMs. It also features M2 slots with extensive PCI-E 5.0 support that extends to both the GPU and the storage options, even as it leverages a large, customizable, and airflow-friendly Lian Li O11 Dynamic EVO XL to fit it all and future add-ons with ease.

One does need to point out that the O11 Evo XL, despite being an excellent case, ships with no fans preinstalled or in the box. To remedy this, users can leverage the Carrara's bundled limited-edition 120mm fan and take inspiration from some of the best cooling fan kits available.

The build leverages a large, but fast 2TB Crucial T700 SSD that ships with a large heatsink (the Carrara has dedicated heat spreaders on all slots that could potentially be used instead, if aesthetics are a concern) to allow users to experience PCI-E 5.0 speeds out of the box. On the cooling front, the Arctic Liquid Freezer III (one of the best coolers in the business) keeps thermals in check, allowing users to eke more performance out of the 7800X3D, which often sees its stacked cache running hotter than the cores underneath it.

To power a PC this impressive, a platinum-rated ASUS ROG Thor PSU rated at 1000W is one of the easiest suggestions to make, as it offers a native 12VHPWR connector, excellent efficiency, and an OLED display (that the O11 EVO XL does sadly conceal) in a neat, but slightly expensive package.

All in all, the updated-for-mid-2024 ultimate RTX 4090 gaming PC is built around maximizing performance while looking at both balance and relative value for money, without compromising meaningfully when it comes to performance for enthusiasts looking for something that can hold its own against the best gaming PCs out there.

    It also throws in a free PSU tester and plenty of cable management options in a package that is surprisingly more affordable than the competition with a 10 year warranty in tow.

  • Hyte Y60 Case
    HYTE Y60

    There is no better mid-tower case to show off gaming rigs than the Hyte Y60. With three tempered glass panels, the Y60 case provides a nearly unobstructed view of the components. A dual chamber design enables builders to keep PSUs and cables tucked behind motherboards to avoid interfering with other components. The Y60 ships ready to vertically mount graphics cards with an included PCIe riser cable. Even with solid glass panels, the case still promotes airflow with extensive vents that wrap around the right side, top, and back of the chassis.

For the fastest Intel-based build possible, the team at Game ZXC pairs Intel's cherry-picked Core i9 14900KS with ASUS's ultimate RTX 4090 GPU variant, the ROG Strix OC. This allows it to leverage Intel's highest-end CPU for its powerful multi-core performance or newer XTU AI performance leeway, as well as its potential APO (Intel® Application Optimization) gains in titles.

The CPU's demanding thermal needs are met by the powerful ASUS Ryujin III AIO, which offers an 8th generation Asetek pump, as well as a cooling fan for on-board VRMs on the ASUS ROG Maximus Dark Hero. That GPU features a 20+1+2 stage configuration, allowing users to push Intel's highest-end desktop-grade CPU even higher.

This build leverages 48GB of Corsair's 7200 MHz Dominators with relatively low latency (CL36) along with a fast 1TB PCI-E 5.0 Teamforce T540 SSD. The T540 recently received a series of price cuts too, putting it in direct price competition with high-end PCI-E 4.0 alternatives.

This build leverages one of the most affordable PCI-E 5.0 and ATX 3.0 PSUs in the business, which is backed by a 10-year warranty by Seasonic, even as it offers a native 12VHPWR connector as part of the package. The suggested Hyte Y60 is a wildly popular option with most PC builders lately thanks to its premium build quality and modding options. Users can also opt for a DIY screen to go with the Y60, since it offers plenty of space for all the components above.

With a focus on value for money, aesthetics, and raw speed above all else, the Intel-themed build above has it all for gamers, productivity enthusiasts, and users who simply want a PC that looks great while running everything cranked up to the maximum possible in 2024.
