It’s Bronze rated but feels very high quality. Being semi-modular is a huge plus because it makes cable management much easier, and the flat black cables look very clean inside the case. It’s quiet and provides plenty of power for a mid-to-high range GPU. ## Frequently Bought Together - Thermaltake Smart BM3 650W 80Plus Bronze ATX 3.0 & PCIE 5.0 Ready Semi-Modular Power Supply; 105°C/221°F Japanese Capacitor; 5 Year Warranty; PS-SPD-0650MNFABU-3 - AMD Ryzen 5 5500 6-Core, 12-Thread Unlocked Desktop Processor with Wraith Stealth Cooler - Cooler Master MasterBox Q300L Micro-ATX Tower with Magnetic Design Dust Filter, Transparent Acrylic Side Panel, Adjustable I/O & Fully Ventilated Airflow, Black (MCB-Q300L-KANN-S00) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/554504044-smart-bm3-650w-80plus-bronze-atx-3-1-and-pcie](https://www.desertcart.co.za/products/554504044-smart-bm3-650w-80plus-bronze-atx-3-1-and-pcie) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-25*
