With support for up to 600 W of power delivery (see below), this cable ensures safe and stable performance for NVIDIA RTX 40 and 50 Series and future high-end GPUs. Enjoy a clean, efficient setup that’s fully compliant with ATX 3.1 and PCIe 5.1 standards.
W pełni zgodny z PCIe 5.1 i ATX 3.1 standardy
12V-2x6 Cable: Up to 450 W power delivery for the 750 W.
12V-2x6 Cable: Up to 600 W power delivery for the 850 W.
The CORE BC-650 complies with ATX 3.1 specifications but is supplied with traditional PCIe connectors instead of a 12V-2x6 cable.
Pełne wsparcie dla starszych procesorów graficznych
To ensure compatibility with older GPUs, the CORE BC ATX 3.1 includes a 2× 8-pin PCIe cable. It delivers reliable power up and works seamlessly with graphics cards from previous generations. This cable makes it easy to upgrade your PSU without changing your GPU—perfect for users who want next-gen power with legacy support.
Dual 8-pin PCIe connectors for broad compatibility
Idealny do kart graficznych z poprzednich generacji
Łatwa instalacja dla użytkowników dokonujących aktualizacji ze starszych systemów
Reliable support for legacy GPU power requirements
S 2 FC – inteligentna technologia sterowania wentylatorem
System Smart and Silent Fan Control (S 2 FC) inteligentnie reguluje prędkość obrotową wentylatora zasilacza, aby zapewnić idealną równowagę między wydajnością chłodzenia a cichą pracą . Dynamicznie dostosowując krzywą wentylatora do temperatury, system zapewnia cichą pracę systemu przy niskim i średnim obciążeniu oraz efektywne chłodzenie, gdy zapotrzebowanie na moc wzrasta.

Często zadawane pytania
CORE BC is the more straightforward entry point in the current CORE family. It combines ATX 3.1 support, fixed cabling and 650 W, 750 W or 850 W output options with an 80 PLUS Bronze efficiency rating. It is aimed at everyday gaming and general-purpose builds where the extra features of the higher series are not required.
Both are efficiency certifications, but Gold requires higher conversion efficiency at the defined certification load points than Bronze. This mainly affects how much input power is lost as heat; it does not by itself describe every other aspect of PSU performance. For a closer look at the efficiency tiers, see our guide to 80 PLUS certification.
No. This is one of the important differences within the range. CORE BC-850 includes a 12V-2×6 connection rated for up to 600 W, while BC-750 provides up to 450 W through its 12V-2×6 cable. CORE BC-650 remains ATX 3.1 compliant but uses traditional PCIe 8-pin connectors instead.
Not necessarily. If the included cables match your system, fixed cabling keeps the PSU simple and avoids having to select modular cables. The trade-off is that unused cables cannot be removed. If full modularity is important for cable management, CORE GX is the better fit.
Start with the hardware rather than the PSU number. A 650 W system does not automatically need 750 W just because a larger model exists, while a more demanding GPU may require both additional wattage and a particular connector configuration. Check the complete build before choosing between 650 W, 750 W and 850 W. For more information on what PSU you should get, use our Wattage Calculator.
