    [Employee of bestbuy] The 12v GPU single cable is a life savor for new 40 and 50 series GPUs. Its also shorter than my 850 giving more cable managment space. fully sleeved cables. I Highly recommend.

  • Great PSU -- Unlisted 12VHPWR power rating.

    Everything about it works great, however the included 12VHPWR was only rated for 300W. The specifications make no mention of the power rating of the 12VHPWR cable. When running the cable on a RTX 4080, it caps the power draw at 290W when the card is capable of 330+W and has more to give. If buying this PSU, check what your cable is rated for as there are multiple cable versions available like the 450W and 600W that your GPU may need.
