1000W Platinum in Vermilion Red for Flagship GPU Hardware: Seasonic Unveils the FOCUS PX-1000 ROSSO and XTIA Chassis Bundle

For decades, PC power supplies have been treated as purely utilitarian boxes meant to be tucked away beneath a steel shroud. Seasonic is flipping that script for open-frame and SFF showcase builders with the launch of the FOCUS PX-1000 ATX 3.1 ROSSO: a limited-edition 1000W Platinum power supply finished in metallic vermilion red, offered both standalone and in a matching bundle with chassis specialist XTIA.
Automotive-Inspired Vermilion Red Finish and Custom Braided Cabling
Named ROSSO in a clear nod to classic Italian racing liveries, this special edition trades the standard matte black or white powder coat for a multi-layer metallic vermilion paint job. Embedded pearlescent flakes allow the red tone to shift subtly depending on ambient studio lighting, complemented by racing checkerboard accents along the edges of its compact 140 mm deep enclosure.
Because every wire stays fully visible on an open test bench or vertical showcase rig, Seasonic includes a complete set of custom red-and-black PET individual braided modular cables straight out of the box. Matching Seasonic-branded cable combs and color-accented connector terminals keep runs razor-straight, including the native 12V-2x6 (PCIe 5.1) cable engineered to deliver up to 600W directly to upcoming 415W GeForce RTX 5080 24GB graphics cards and flagship GPUs without clunky adapters.
OptiSink Internal Layout, Dual Platinum Efficiency, and Cybenetics A+ Acoustics
Beneath the automotive finish lies Seasonic's latest FOCUS v4 ATX 3.1 electrical architecture. Built around an APFC, Full-Bridge LLC resonant converter, synchronous rectification, and DC-DC topology, the unit relies exclusively on 105°C-rated Japanese electrolytic capacitors. Its single +12V rail outputs up to 83A (996W), providing rock-solid voltage regulation during transient power spikes or heavy tuning sessions such as extreme 3.9 GHz overclocking on the Radeon RX 9070 GRE.
Thermal management benefits from Seasonic's redesigned OptiSink PCB architecture. By replacing bulky traditional heatsinks with surface-mount (SMD) MOSFETs and components soldered directly onto a thermally enhanced board, heat dissipation improves by up to eight times while freeing roughly 48% more internal airflow space. Combined with a 135 mm Fluid Dynamic Bearing (FDB) fan governed by digital OptiSilent hybrid control, the PSU secures both 80 PLUS Platinum and Cybenetics Platinum efficiency badges alongside a whisper-quiet Cybenetics A+ acoustic certification.
The Coordinated XTIA Xproto-Z Open-Frame Chassis Bundle
To give this colorway the stage it deserves, Seasonic partnered with boutique case maker XTIA to create a matching edition of the XTIA Xproto-Z vertical open-frame chassis. CNC-machined from thick aluminum with a 4 mm perforated main spine and VESA mount compatibility, the Xproto-Z wears the exact same metallic vermilion red finish, turning the PSU and its braided cables into the visual centerpiece of the build.

Initially rolling out in Asian retail channels, the standalone Seasonic FOCUS PX-1000 ATX 3.1 ROSSO carries a list price of 1,699 RMB (roughly $240 USD before tax), while the matching XTIA Xproto-Z ROSSO chassis bundle (capped at an initial run of 100 sets) is priced at 2,399 RMB (around $335 USD), backed by Seasonic's full 10-year warranty.
My Take on This Spec Sheet
We have not yet had a physical unit on our desk, but pairing a compact 140 mm Platinum power supply directly with a CNC-machined XTIA Xproto-Z open-frame chassis makes complete sense on paper. Enthusiasts building on open airframes routinely spend an extra $80 to $120 on third-party custom sleeved cables just to make their wiring look presentable. By bundling pre-combed red-and-black PET braided 12V-2x6 cables with a proven OptiSink ATX 3.1 platform and a matching aluminum frame, Seasonic and XTIA turn a component most builders hide into an authentic desk centerpiece. If the team at Seasonic wants to send a ROSSO unit over to our lab to stress-test its 12V rail stability on an open bench, our doors are wide open.
