Asus ROG G700 (2025) (Ultra 9 285K / RTX 5090 / 128GB RAM / 2TB SSD)

Manufacturer: Asus

The Asus ROG G700 (2025) is a high-specification ATX desktop gaming PC built around Intel's Ultra 9 285K processor and NVIDIA's RTX 5090 graphics card. With 128GB of DDR5 RAM and a 2TB NVMe SSD, the system is configured for workloads that demand substantial memory headroom alongside fast storage access. Its ATX form factor gives it a footprint suited to a full-size tower build, measuring 510 mm in height and 185 mm in width.

On the graphics side, the RTX 5090 carries 32GB of GDDR7 VRAM across a 512-bit memory bus, delivering a maximum memory bandwidth of 1792 GB/s and a floating-point throughput of 104.9 TFLOPS. The GPU operates on a Blackwell architecture built at 5 nm, supports DirectX 12 Ultimate, PCIe 5, ray tracing, and DLSS, and can drive up to four displays simultaneously via four DisplayPort outputs and two HDMI 2.1b ports. The Intel Ultra 9 285K CPU runs across 24 threads using a big.LITTLE configuration, with P-cores at 3.7 GHz and E-cores at 3.2 GHz, a turbo ceiling of 5.7 GHz, and a 575W TDP rating. Connectivity includes Wi-Fi 6E, Bluetooth, a single RJ45 port, and a varied USB layout spanning USB 2.0, USB 3.2 Gen 1, and USB 3.2 Gen 2 ports in both Type-A and Type-C configurations.

Pros
  • The graphics card carries 32GB of GDDR7 VRAM across a 512-bit bus, supporting up to four simultaneous display outputs via four DisplayPort and two HDMI 2.1b ports
  • 128GB of DDR5 RAM running at up to 6,400 MHz represents the maximum supported capacity for this platform, leaving no room for future memory upgrades
  • Wi-Fi 6E support alongside Bluetooth and a wired RJ45 port gives the system a full set of networking options without relying on a single connection method
  • The CPU uses a big.LITTLE hybrid core layout with an unlocked multiplier, allowing clock speeds to be adjusted beyond factory settings
  • ECC memory support adds a layer of data integrity checking that is uncommon in standard desktop gaming configurations
  • The 2TB NVMe SSD provides a substantial amount of fast storage accessible directly through the primary storage interface
Cons
  • A 575W CPU TDP rating places significant demands on power delivery and cooling infrastructure
  • The system has no USB 3.2 Gen 2 Type-A ports, no USB 4 ports, and no Thunderbolt 3 or Thunderbolt 4 connectivity, limiting high-bandwidth peripheral options
  • 128GB is both the installed and maximum supported RAM capacity, meaning there is no headroom for memory expansion
  • The ATX form factor with a volume of nearly 39,721 cm³ makes this a large and space-demanding build
  • Air-water cooling is not included, so thermal management depends entirely on whatever cooling solution is separately provided
  • The overclocked PassMark result of 67,872 shows only a marginal improvement over the stock result of 67,565, suggesting limited gains from overclocking the CPU
Who is this for?

This desktop gaming PC is well-suited to users who require sustained heavy workloads across multiple demanding applications simultaneously, given its 128GB of DDR5 RAM and 24-thread CPU with a hybrid core layout. The RTX 5090 with 32GB of GDDR7 VRAM and support for ray tracing, DLSS, and up to four simultaneous display outputs makes it a strong fit for users running multi-monitor setups or GPU-intensive rendering tasks. The 2TB NVMe SSD and ECC memory support also make this configuration relevant to workstation-adjacent users who need both fast storage throughput and data integrity alongside gaming use.

Who is this NOT for?

Users with limited physical space will find the ATX form factor and nearly 39,721 cm³ volume impractical, as the chassis demands a dedicated large-footprint environment. The absence of Thunderbolt 3 or Thunderbolt 4 ports and the lack of any USB 4 connectivity make this a poor fit for users who depend on high-bandwidth external devices such as fast external storage arrays or professional audio and video interfaces. Additionally, since 128GB is both the installed and the maximum supported memory capacity, anyone anticipating future memory expansion beyond this ceiling will find the platform offers no upgrade path in that regard.

Final Verdict

The Asus ROG G700 (2025) with the Ultra 9 285K and RTX 5090 is a purpose-built desktop configuration that leaves little ambiguity about its intended workload. Its most defining characteristic is the 32GB of GDDR7 VRAM paired with 104.9 TFLOPS of floating-point throughput, which positions it firmly within a tier of systems designed for sustained GPU-intensive use rather than casual computing. The 128GB DDR5 RAM ceiling, while generous at current standards, also marks the platform's hard memory limit, and the absence of Thunderbolt and USB 4 connectivity narrows its appeal for users with demanding external peripheral ecosystems. That said, for users whose workflows genuinely stress high VRAM capacity, multi-display output, fast NVMe storage, and a high-thread-count CPU with an unlocked multiplier, this configuration addresses those needs in a single cohesive build — making it a compelling option for those whose requirements align precisely with what it offers.
