    I take my reviews very seriously, so with that being said it will be an understatement to say how good quality this product is. I did research so much about this that I end up learning a lot more that I expected. Be aware!!! Lower watt products with a high end computer will not push the best out of your PC components regardless of the minimum requirements. This product is just AMAZING! I saw a huge difference from an older and generic version of this PSU.

    While ppl claim you should never need this large of a PSU. I have a 3080ti oc, i9 10th Gen OC, 6 led strips, 11led fans , LCD aio cooler, a long with 6 SATA drives and 2 nvme drives, 64gb rgb ram. I felt I rather have as much power as a washing machine. Only issue I have is the PSU does not come with cable mod cords and for the price it should l.

    Bought this to replace an aging RM750 that I had used for my previous build for nearly 4 years. That PSU never had any hiccups or problems, I just replaced it because I had bought a beefier GPU that needed 3 PCIe connectors. This one is a little bit bigger, but still works just as well. Is very quiet, have not had any issues with my new setup. In hindsight might have spent a little more for a higher efficiency version (80Plus Titanium).

    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.

    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.
