The COUGAR GR 1000W retains a compact 150mm chassis, making it suitable for a wide range of ATX-compatible cases. Compared to the GLE 1000, the GR 1000 adopts a simpler, more conventional fan grille design, although the addition of the COUGAR badge at the centre gives the unit a more refined appearance.


One side of the PSU features the specifications label containing the unit's electrical ratings and certifications. Like the GLE series, this label is positioned on the side that typically faces inside in cases with a bottom-mounted PSU, keeping it out of sight and helping maintain a cleaner, more minimalist system aesthetic.


The COUGAR GR 1000W features a fully modular cable design for easier cable management and cleaner system builds. Compared to the GLE 1000, COUGAR has also improved the orientation of the modular connectors. The upper row retains the locking tabs on the top, while the lower row places them underneath, making the release clips much easier to access when disconnecting cables. It's a small but thoughtful refinement that improves usability during installation and maintenance.


The rear of the GR 1000 features a conventional ventilation grille alongside the AC power socket and power switch. There is no dedicated switch for enabling an intelligent or semi-passive fan mode, meaning the cooling fan operates using a fixed active profile.
