RTX 5090 Waterblock Design and Power Connector Cooling

Question

Dear Bitspower Team,

I hope this message finds you well.

I am considering using your custom waterblock for the NVIDIA GeForce RTX 5090 graphics card and would like to ask a technical question regarding the design.

Given the recurring concerns in the community about the 12V-2×6 (16-pin) power connector melting on RTX 5090 cards, I am wondering if your waterblock includes any specific features—such as passive or active thermal management—designed to help cool the connector area or reduce the thermal load around the power connection.

Any information regarding this aspect of your design would be greatly appreciated, especially if your solution offers an advantage over reference designs in terms of connector safety and long-term reliability.

Thank you in advance for your time and support.

Best regards,
Derek

Dear Derek,

Thank you for contacting Bitspower.
Yes, we’re aware that the power connector gets hot.
That’s why our backplate is designed to cover the power connector and help dissipate the heat.
The water block is BPM-VG5090ASA.
Here is the link.

Does TUF waterblock also have the extended backplate for helping dissipating heat from power connector also?
