UNIVERSAL ATX COMPATIBILITY
Your RTX 3000 series GPU is universal. It will work with any standard ATX system as long as there's enough room in the case and the wattage to support it. Cooler Master believes your PSU should work the same way. One new part shouldn't force you to have to change your power supply unit, and with the 12-Pin to 2x8-Pin VGA Adapter you won't have to. You can use this adapter to power your RTX 3000 GPU, or any future 12-pin connector GPU, regardless of what brand your PSU comes from.
