Its fully modular design and ease of installation are also frequently praised, simplifying cable management and the overall building process. While some users noted its larger size, the positive feedback overwhelmingly focuses on its reliability and value. The power supply is considered a great option for its price point.

    Why only 2 PCIE cables... goodbye 3080 upgrades.

    Um love everything about this power supply. However it should come with 3 pcie cables. That to me is kind of a big deal. Considering i have one thats an older model that came with 3. That allowed me to uprgade to a 3080ti. If you know anything about buying power supply cables for specific models of PSU. Then you know how important it is to get that very specific cable. Because you cant just mix match cables from other power supplies in rigs without taking major risks. I think they seriously need to fix this...

    No, I would not recommend this to a friend

      Posted .

      Hello Mathias,

      This unit does include 4 PCIe connectors which would be more than enough for any 1 single card.

      If you have any further questions please contact our team directly on our site.
