Choose the right wattage
| Model | 12 V current | Best suited to |
|---|---|---|
| CORE BC-650 | 54 A (648 W) | Mainstream gaming, e.g. RTX 4060/4070 class |
| CORE BC-750 | 62 A (744 W) | Balanced choice for a more powerful GPU and future-proofing |
| CORE BC-850 | 70 A (840 W) | High-end GPUs and demanding systems |
Important information about the product variants
All three wattages have 24-pin ATX, 8-pin CPU (EPS12V), SATA and Molex connectors. The difference is in the PCIe connection: the 750 W and 850 W models have a native 12V-2x6 cable (ATX 3.1/PCIe 5.1) for direct connection to modern graphics cards, while the 850 W model also adds an extra traditional PCIe cable (6+2 pin). The 650 W model is ATX 3.1 compatible but uses traditional PCIe connectors (6+2 pin) only, without a native 12V-2x6 cable.

PC & HiFi Örebro recommends
Seasonic CORE BC is a dependable and sensible choice for serious PC builds where stable operation and compatibility with modern graphics cards are priorities. Choose 650 W for mainstream gaming systems, 750 W for a balanced and future-ready build, and 850 W for high-end GPUs with higher power requirements. If you need modular cabling for easier cable management in a compact case, we recommend looking at Seasonic's modular series instead.
