Review: Quality cables and 12vhpwr is nice - Nice psu came with all the cables I needed, heavy duty cables too. the 12vhpwr connector is nice hooked right into my 4070 super for a clean look no pigtails or split connectors needed. Mobo connector is a bit tight but just have to wiggle it.
Review: Would buy again (I did x3) - Great product, I have no complaints. I originally bought the 700w version, to run a CPU mining rig. It runs so stable that I put 2 other rigs on the same PSU. This type of use case is similar to product testing. There are a lot of both hard and soft resets, as well as drastic changes in load. I love the fully modular option for this PSU. There are plenty of cables, including sperate CPU and PCI-e cables. I purchased a second 700w not long ago to run more of my miners. I was so pleased with the product I also purchased a 850w for my own personal workstation. Good buy.

The xpg looks and feels like a higher price power supply. It stays quiet even when taxing my modern PC build. Plenty of slightly stiff good looking cables included.
