    Good value for the wattage and 80 plus gold rating. Large fan for good cooling and quieter operation. Lots of connections for CPU/PCI-E and peripherals. Downside is it comes with 3 CPU cables and 3 PCI-E (2x 6+8pin). Ideally it should have 4 PCI-E cables for running up to 2 high end GPUs. I know SLI/Crossfire is generally not a thing anymore and not recommended. However, I don't think I've seen a motherboard that needs 3 8pin CPU connections. Maybe an extreme overclocking board. Other thing to note is the cables have an extremely stiff heat shrink tubing at the ends of the cables. This can make them very difficult to bend, such as for the CPU 8pin cables.

    Once I discovered modular power sources it became the only kind that I will buy. Couple that with the high quality of Corsair products; you can't miss with this PSU. So easy to set up and never wavers in power production.

    Good modular power supply. Do note that you will need to check compatibility of your current cables or use the included cables when replacing another modular PSU. So be prepared for possibly some rerouting of cables.
