Flex ATX PSU Recommendations with PCIe connector support for dedicated GPU

Power Power Supplies (off-board)
1

Hi, I would like to have some recommendations for Flex ATX power supplies that match the following requirements:

  1. Flex ATX, 5.90" L x 3.21" W x 1.59" H (150.0mm x 81.5mm x 40.5mm)
  2. Around 500W
  3. Must have 6+2 pin PCIe connector for dedicated GPU usage.

I tried my best to search for power supplies with these requirements, but there is no listing that fulfill all of the requirements. However, I have found one power supply unit that matched exactly the requirement, FSP650-50FUB, outside of DigiKey website, which does not exists within the DigiKey website.

Is it possible to have a quotation on this product for me to make an order in Malaysia, or suggest me some alternatives that match the exact requirements?

Thank you and have a nice day.
