Best GeForce RTX 3090 Prebuilt PCs in 2023

Getting your hands on a new Nvidia GeForce RTX 3090 ranges from difficult, to almost impossible; seeing as how quickly this GPU sold out and how little initial stock Nvidia offered.

Of course, this issue is only exacerbated by the number of scalpers that purchased both Nvidia and AMD’s newly released GPUs, in order to resell them at higher prices and make a quick profit.

An alternative to making these scalpers gleeful, by purchasing their vastly overpriced GPUs, is finding a solid pre-built PC that you can use, and later customize as you see fit.

Currently, there are two such options that include the Nvidia GeForce RTX 3090 at a reasonable price for the peripheral hardware components they include.

In this article, we will analyze both PC builds, and see whether or not they are worth their asking price.

Best NVIDIA RTX 3090 Prebuilt Gaming PCs

CUK Continuum

Nvidia Geforce RTX 3090 + Intel Core i9-10900KF

Brand	Computer Upgrade King
Graphics Coprocessor	NVIDIA GeForce RTX 3090
Operating System	Windows 10 Home
CPU Model	Core i9
Hardware Interface	USB

Though a bit costly, Computer Upgrade King (CUK) has two pre-built PCs that feature the Nvidia GeForce RTX 3090 GPU and the Intel i9-10900 Series CPU. In fact, this CPU is the i9-10900KF series, which is almost identical to the i9-10900K variant but does not come with an integrated Intel UHD Graphics 630 graphical processor – making it cost slightly less. The i9-10900K(F) includes 10 cores, 20 threads, a base clock speed of 3.7 GHz, and a boost clock speed of 5.3 GHz.

The difference between the two CUK pre-built PCs is that one has 64 GB of RAM, 1 TB NVMe SSD, and a 2 TB HDD, while the other has a total of 2 TB of NVMe SSD storage, 4 TB of HDD storage, and 128 GB of RAM.

The model of the GeForce RTX 3090 and the Z490 motherboard is not disclosed, as they will vary depending on availability. The PC does come with an 850 Watt 80 PLUS Gold certified PSU, a gaming keyboard and mouse, five ARGB cooling case-fans (three front, two top, and one rear), and a liquid AIO CPU cooler – the radiator size of which is unknown.

One major downside to this pre-built computer is the RAM. Both the 64 GB and the 128 GB versions of this PC use 2,933 MHz RAM, which will certainly throttle the capabilities of the Intel i9-10900KF. In fact, Gamer’s Nexus has proven that without the proper RAM, the Intel i9-10900K(F) can be outperformed even by the much cheaper i5-10600K. The RAM is a component that will definitely need to be replaced, at least in the long run.

The case has a stylish ARGB display in the front and a tempered-glass side panel that swings open for easy access to the interior.

Though most components within the CUK Continuum are unknown, the fact that it has a solid case, CPU, and GPU, means that it can always be further customized down the line. Of course, these components do come at a hefty price of $4,049.99 (for the 64 GB of RAM and 3 TB of storage) and $4,399.99 (for the 128 GB of RAM and 6 TB of storage) – but, once again, we would recommend the cheaper option, as the RAM will need to be replaced.

Skytech Omega Gaming

Nvidia Geforce RTX 3090 + Intel Core-i9 10900K

Brand	Skytech Gaming
Graphics Coprocessor	GeForce RTX 3090 24G GDDR6X
Operating System	Windows 10
CPU Model	Core i9
Hardware Interface	USB, DisplayPort, HDMI, USB 2.0

For gaming enthusiasts that want their PC to have both performance and extravagant looks, Skytech’s Omega Gaming prebuilt PC has plenty to offer. Firstly, of course, it features an Nvidia GeForce RTX 3090 GPU – though the brand of the aftermarket model may vary, depending on what they have in stock – some buyers mention receiving an MSI Trio X model of the GPU, while others a PNY XLR8 variant. This is to be expected with a pre-built PC, as stock for the GeForce RTX 3090 is still scarce.

In terms of its CPU, this desktop features an Intel Core i9-10900K, so its gaming and single-core performance will be in the upper echelon of what the current generation of hardware can process.

Next, for RAM, we have 32 GB of G.Skill’s TidentZ RGB model, in four ranks of 8 GB. This RAM will have a base frequency of 3,600 MHz, but it is unclear what Column Access Strobe (CAS) latency these units will have. At 3,600 MHz, the most optimal latency would be 16 cycles, which hopefully it includes. 32 GB of RAM is plenty for most gaming builds, but additional RAM storage may be needed for those looking to use the PC for streaming or content creation.

The motherboard included will, most likely, be the ASRock Z490 Phantom Gaming Velocita. This motherboard has a 10+2+1 (13-phase) VRM solution that uses SIC654A/SIC632A 50-amp MOSFETs and 60-amp power chokes – and all MOSFETs are heatsinked. It has four DDR4 DIMM slots, a standard, yet solid, Realtek ALC1220 audio codec, which includes a 120 dB differential amplifier, two armored M.2 slots (1 TB NVMe drive included), and a ton of connectivity (including a Thunderbolt AIC connector). Overall, a solid option for a motherboard – not high-end, but it works for this build.

The power supply is one component that may need replacing, as it is 850 Watts (on the lower end for an Intel i9-10900K and a GeForce RTX 3090 GPU, both of which are power demanding), and it appears to have only an 80 PLUS White certification, meaning a power efficiency of just the baseline 80 PLUS value (80%). This is common in pre-built PCs, as the power supply is often overlooked. We would recommend a 1,000 Watt PSU with a Platinum (or at least Gold) 80 PLUS certification to replace this piece.

Another set of components that are often overlooked comprises the PC’s cooling solution. For this case, we have a 360 mm AIO liquid cooler for the CPU, four Jupiter AJ 120 mm fans, and one 80 mm rear fan. Because the fans are not of the best quality, and the case itself has a tempered glass side panel – so it is not optimized for quiet operation – the PC can get loud, with one user reporting 59 decibels of noise emissions emanating from the case.

All in all, for those looking to purchase a gaming PC that is visually appealing and includes the Nvidia GeForce RTX 3090 GPU, the Skytech Omega Gaming PC desktop is a solid option and is currently priced at $3,549.99.

Final Thoughts

Both of these PC builds are great choices for those who are looking for a top-of-the-line gaming experience with the Nvidia GeForce RTX 3090 can offer. While it is true that both will cost you a pretty penny, they will fulfill your gaming dreams as long as you’re willing to invest in them.
