Ultimate White RTX 5090 Gaming PC for 4K Gaming
The CAA Phantom White RTX 5090 Gaming PC is built for customers who want flagship gaming performance without cheap supporting components, mystery OEM hardware or poor factory configuration.
Powered by the AMD Ryzen 7 9800X3D and Gigabyte GeForce RTX 5090 32GB, the Phantom is designed for extreme 4K gaming, high-refresh-rate displays, ray tracing, VR, streaming and demanding creator workloads.
This is not simply an RTX 5090 installed into the cheapest possible platform.
The Phantom combines NVIDIA’s flagship graphics card with a premium ASUS ROG STRIX motherboard, 64GB dual-channel DDR5-6000 memory, ARCTIC 360mm liquid cooling, 2TB NVMe storage and a 1000W fully modular power supply.
Every system is professionally built, BIOS optimised, drivers installed, stress tested and supplied with a 12-month CAA Computers warranty.

This is the type of system you buy when you want to stop wondering whether your gaming PC is powerful enough.
Ryzen 7 9800X3D + RTX 5090
Putting an RTX 5090 into a gaming PC is only part of building a properly balanced flagship system.
The AMD Ryzen 7 9800X3D uses AMD’s 3D V-Cache technology and is designed around high-performance gaming.
It gives the RTX 5090 a powerful gaming-focused CPU platform rather than pairing an extremely expensive graphics card with a processor chosen simply to reduce the advertised price.
For customers searching for a 9800X3D RTX 5090 gaming PC, this is exactly the combination the Phantom is built around.
64GB DDR5-6000 in Dual Channel
A specification saying 64GB RAM doesn’t tell you how that memory has been configured.
The CAA Phantom uses:
2 × 32GB DDR5-6000
That gives the system a proper dual-channel memory configuration.
CAA Computers does not use a single RAM stick simply because it makes the build cheaper.
Dual-channel memory provides greater memory bandwidth than a comparable single-channel configuration and can benefit gaming performance, frame-time consistency and 1% low FPS in CPU-sensitive situations.
For a flagship RTX 5090 gaming PC, cutting corners on memory configuration makes little sense.
Premium Retail Components Instead of Mystery OEM Parts
One of the biggest problems when buying an expensive gaming computer is that the headline specifications don’t always tell you what’s actually inside.
A listing might advertise:
RTX 5090
64GB RAM
2TB SSD
while saying very little about the motherboard, power supply, cooling or exact memory configuration.
The CAA Phantom uses named retail hardware from established PC component manufacturers:
- AMD
- Gigabyte
- ASUS ROG
- TEAMGROUP
- ARCTIC
- Crucial
- NZXT
- SilverStone
You know what you’re paying for before you buy.
There is no mystery OEM motherboard, generic power supply or proprietary hardware hidden behind vague product descriptions.
Built to Last and Built to Be Upgraded
The CAA Phantom uses AMD’s modern AM5 platform and standard retail PC components.
That means the computer is designed to remain serviceable and upgradeable rather than becoming difficult to modify later.
Future upgrades can include:
- Additional NVMe SSD storage
- Higher-capacity DDR5 memory
- Future compatible AM5 processors
- Cooling upgrades
- Graphics card upgrades
- Power supply replacement
- Additional fans
You aren’t locked into a proprietary OEM chassis or motherboard layout.
For a PC at this price level, that matters.
Gaming-Optimised BIOS
Expensive components don’t automatically mean an optimised gaming PC.
Before your Phantom leaves CAA Computers, the BIOS and system configuration are checked for the installed hardware.
Where supported, we configure and verify settings including:
- DDR5 memory profile
- Correct memory speed
- Resizable BAR
- UEFI configuration
- Fan operation
- Cooling configuration
- Boot configuration
- Hardware detection
- Gaming-focused system settings
We don’t simply assemble the PC, see that Windows starts and call the job finished.
Drivers Installed Before Delivery
Your CAA Phantom arrives with the important system drivers already installed.
This includes:
- NVIDIA GeForce graphics drivers
- AMD chipset drivers
- ASUS motherboard drivers
- Wi-Fi drivers
- Bluetooth drivers
- LAN drivers
- Relevant Windows updates
You shouldn’t need to spend the first few hours with your new RTX 5090 gaming PC searching manufacturer websites and troubleshooting missing devices.
Plug In and Play
The Phantom is supplied as a ready-to-play gaming PC.
Connect your:
Monitor
Keyboard
Mouse
Internet
Sign into Windows, install your games and start playing.
The computer has already been assembled, configured and tested.
Professionally Stress Tested
A flagship gaming computer should be tested under sustained load before it reaches the customer.
Every CAA Phantom undergoes testing that includes:
- CPU stress testing
- GPU stress testing
- Memory testing
- Temperature monitoring
- Cooling checks
- Driver checks
- Stability testing
- Hardware inspection
- Final system check
We would rather identify a problem on our workbench than have you discover it after delivery.
12-Month CAA Computers Warranty
The CAA Phantom includes a 12-month CAA Computers warranty.
If there is a covered problem with the system during the warranty period, you deal with CAA Computers rather than being left to diagnose which individual component manufacturer you need to contact.
That gives you a single point of contact for the complete PC.
Individual retail components may also carry their own manufacturer warranties beyond the CAA warranty period, subject to the relevant manufacturer’s terms.
Premium White RTX 5090 Gaming PC
The Phantom has been designed to look like a flagship system as well as perform like one.
The build combines:
- White NZXT H9 Flow RGB case
- White ASUS ROG STRIX motherboard
- White ARCTIC 360mm liquid cooler
- White RGB DDR5 memory
- RGB intake fans
- RGB rear exhaust fan
- Clean white cabling
- Panoramic tempered glass
The result is a white RTX 5090 gaming PC designed to be displayed as part of a premium gaming setup rather than hidden beneath a desk.
