Phanteks Eclipse P400 Air Midi Tower DRGB Case – Black
The Phanteks Eclipse P400 Air is a mid‑tower chassis that blends robust construction, versatile cooling options and striking aesthetics into a single package. Designed for gamers and enthusiasts who demand both performance and style, this case delivers an impressive array of features while maintaining a sleek black finish.
Form Factor & Dimensions
The P400 Air is built around the mid‑tower form factor, measuring 210 mm wide, 465 mm high, and 470 mm deep. Its compact footprint fits comfortably in most rooms while still offering ample room for expansion. The chassis supports a wide range of motherboard sizes: from E‑ATX down to Mini‑ITX, making it suitable for both large desktop builds and small, high‑performance systems.
Material & Build Quality
The exterior is finished in a durable powder‑coated steel shell that resists scratches and fingerprints. The front panel features a generous tempered glass side window, allowing users to showcase their internal components while providing a clear view of the case’s interior layout.
Cooling & Fan Support
The P400 Air is engineered for optimal airflow:
- Front: Supports either three 120 mm fans or two 140 mm fans. The chassis comes pre‑installed with three 120 mm D‑RGB fans, ensuring a vibrant and efficient cooling solution.
- Top: Accommodates up to two 120 mm or 140 mm fans for additional heat dissipation from the GPU area.
- Rear: Supports one 120 mm fan, completing a balanced airflow path from front to back.
The case also allows for a maximum CPU cooler height of 160 mm, giving users flexibility when selecting high‑performance air or liquid coolers.
Expansion & Drive Bays
- PCIe Slots: Seven full‑height expansion slots provide ample room for multiple GPUs, sound cards, and other expansion cards.
- Drive Bays: Two 2.5″ bays and two 3.5″ bays enable users to install SSDs, HDDs, or additional storage devices without compromising space.
- Internal Expansion Bays: Two 2.5″ slots and two 3.5″ slots are available for extra expansion cards or accessories.
Power Supply Compatibility
The chassis supports standard ATX power supplies up to 270 mm deep. This ensures compatibility with a wide range of modern PSU models, including those featuring high‑efficiency 80 PLUS certifications (even though the P400 Air itself is not rated for any specific efficiency level).
Connectivity & Front Panel Features
The front panel offers:
- Two USB 3.0 ports for high‑speed data transfer.
- A dedicated headphone jack and a microphone input, both using the standard 3.5 mm connector.
- Separate audio jacks for enhanced sound quality.
RGB & User Controls
The P400 Air includes built‑in D‑RGB fans that can be synchronized with other RGB components via Phanteks’ software. The chassis also features a D‑RGB mode button, allowing users to toggle lighting effects directly from the case without needing additional hardware.
Dust Management & Cable Routing
To maintain airflow and keep the interior clean, the case incorporates a dust filter on the front panel. Additionally, an integrated cable management system helps users route cables neatly behind the motherboard tray, improving both aesthetics and airflow efficiency.
Maximum Component Compatibility
- GPU Length: Supports graphics cards up to 420 mm in length (or 280 mm when the HDD cage is installed).
- Motherboard Size: Compatible with E‑ATX, ATX, Micro‑ATX, and Mini‑ITX boards.
- CPU Cooler Height: Up to 160 mm, accommodating most air coolers and many AIO liquid cooling solutions.
Weight & Build Footprint
The chassis weighs approximately 7 kg, a typical weight for mid‑tower cases of this size. Its dimensions make it easy to transport between workstations or gaming rigs while still providing ample internal space.
Why the Phanteks Eclipse P400 Air Stands Out
The combination of a sturdy steel frame, tempered glass side panel, and comprehensive cooling options makes this case an excellent choice for users who want a balance between performance, expandability, and visual appeal. Its RGB integration adds a modern touch without compromising functionality.
Key Takeaways
- Mid‑tower chassis with versatile motherboard support (E‑ATX to Mini‑ITX).
- Robust construction: powder‑coated steel and tempered glass side panel.
- Excellent airflow: front, top, and rear fan support with pre‑installed D‑RGB fans.
- Extensive expansion options: seven PCIe slots, multiple drive bays, and ample PSU compatibility.
- Integrated RGB controls and dust filters for a clean, customizable build environment.
The Phanteks Eclipse P400 Air is engineered to meet the demands of gamers and PC builders who require a reliable, high‑performance case that also delivers on style and expandability. Its thoughtful design ensures that every component can be installed with ease while maintaining optimal airflow and cable management for a clean, efficient build.
