This article covers ASUS TUF Gaming NVIDIA GeForce RTX 3080 OCエディション グラフィックカード (PCIe 4.0 10GB GDDR6X HDMI 2.1 DisplayPort 1.4a デュアルボールファンベアリング ミリタリーグレード認証 GPU Tweak II).

Overview

The ASUS TUF Gaming NVIDIA GeForce RTX 3080 OC Edition is a graphics card built for those who value reliability as much as raw performance. Based on NVIDIA's Ampere architecture, this card packs 8704 CUDA cores, 10GB of GDDR6X memory, and a factory-overclocked boost clock that pushes it beyond the standard Founders Edition specs. It's designed to handle 4K gaming, high-refresh-rate 1440p, and demanding creative workloads with ease. What sets the TUF Gaming series apart is its focus on durability. Military-grade capacitors, an all-metal shroud, and dual-ball bearing fans are standard here. The card also features ASUS's Axial-Tech fan design with a reversed center fan to reduce turbulence, making it one of the more thermally efficient RTX 3080 variants on the market. In the GPU hierarchy, the RTX 3080 sits comfortably in the high-end segment, just below the RTX 3090 and 3080 Ti. The OC Edition adds a modest performance bump out of the box, making it a strong choice for enthusiasts who want premium build quality without the premium price tag of a flagship.

Compatibility Guide

Interface: PCI Express 4.0 x16 (backward compatible with PCIe 3.0) Power: Requires two 8-pin PCIe power connectors. A 750W power supply is recommended, though 850W is safer for systems with a high-end CPU. Physical size: Approximately 299.9 x 126.9 x 51.6 mm (2.7-slot design). Measure your case's maximum GPU clearance before purchasing. Outputs: 2x HDMI 2.1, 3x DisplayPort 1.4a. HDMI 2.1 supports 4K at 120Hz on compatible TVs. * Motherboard compatibility: Works with any motherboard that has a PCIe x16 slot. No special chipset requirements.

Product Info

Released in late 2020, the ASUS TUF Gaming RTX 3080 OC Edition originally carried an MSRP around $700-750 USD, though market pricing has fluctuated significantly since launch. It comes with a standard 3-year manufacturer warranty (check regional terms). Market positioning: This is a high-end card with a focus on durability and quiet operation. It's not the flashiest RTX 3080 (minimal RGB), but it's one of the most robust. The TDP is rated at 320W, and the triple-fan Axial-Tech cooler handles that heat load effectively in most well-ventilated cases.

Best Use Cases

4K Gaming Enthusiasts The RTX 3080 delivers 60+ fps in most modern titles at 4K Ultra settings, especially with DLSS enabled. If you're building a rig around a 4K 120Hz display, this card is an excellent match. However, if you primarily play esports titles at 1080p, a lower-tier card like the RTX 3060 would be more cost-effective. Content Creators (Video Editing / 3D Rendering) With 8704 CUDA cores and 10GB of VRAM, this card accelerates Premiere Pro, DaVinci Resolve, and Blender workflows significantly. The 10GB frame buffer is sufficient for 4K timelines and moderate 3D scenes. For 8K projects or heavy 3D simulations, consider the RTX 3090's 24GB. * Long-Term Builders Seeking Reliability The TUF Gaming series is built to last. Military-grade capacitors, dual-ball bearing fans (rated for 2x the lifespan of sleeve bearings), and a reinforced metal backplate make this a card you can trust for years. If you plan to keep your build unchanged for 4-5 years, this is a solid investment.

Things to Consider

First, the size: at nearly 300mm long, this card will not fit in many small-form-factor or budget mid-tower cases. Always check your case's maximum GPU length before buying. The 2.7-slot thickness also means it will block adjacent PCIe slots on most motherboards. Second, power consumption. 320W TDP is substantial. In a case with poor airflow, or during summer months, the card may run hotter and noisier than expected. Pair it with a case that has good intake and exhaust fan configuration. Third, competition. Other RTX 3080 cards like the MSI Gaming X Trio or GIGABYTE GAMING OC offer similar performance with different cooling solutions. The TUF Gaming excels in build quality and noise levels, but its boost clock may be slightly lower than some factory-overclocked rivals. If you want the absolute highest clock speeds, the ASUS ROG STRIX variant is worth a look. ## FAQ
Q: Can I use this card with a PCIe 3.0 motherboard? A: Yes, it is fully backward compatible. In gaming, the performance difference between PCIe 3.0 and 4.0 is negligible (1-3% at most). Only in specific bandwidth-intensive compute tasks might you see a small gap. Q: Is 10GB of VRAM enough for future games? A: As of 2026, 10GB is still sufficient for 4K gaming in most titles, but some newer games with ultra-high texture packs recommend 12GB or more. If you plan to keep the card for 3+ years and always play at maximum settings, consider a 12GB+ model. Q: Does this card have RGB lighting? A: Very minimal. The TUF Gaming series focuses on a subdued aesthetic. There is a small illumin
