    Great for current gen pc builds , only complaint is the lack of individual pci cables , only pci cables included are 3 double connector cables which is the reason for only 4 stars

    One of the best power supplies out there, and runs a system with a 3090 gpu without any issues. Would recommend if you need the extra wattage!

    The power supply has modular wiring that allows you to only use the needed wires at the moment. The wires are labeled for easy use and to identify.

    Works well and the cables aren’t too stiff to move around in the case. Comes with the right amount of cables for the job!

    Great unit but misleading...

    To be clear.. it's a solid unit. Price is good.. but misleading as it doesn't include ALL the cables associated with the expansion ports. Found myself having to purchase additional cables as the unit didn't come with all the sata, PCIe, etc etc cables to actually load up the unit.

    No, I would not recommend this to a friend
