XPG tries hard to deliver good and reliable PSU products. This brand has "proper" PSU PMs who try to improve the designs they use and not just take a platform from the shelf and put their badges on. The new Cybercore series has one of the best fans we have ever encountered in PSUs, a double-ball bearing Nidec with increased cost.
The build quality of the Cybercore 1000 is excellent since XPG and CWT paid extra attention to all details. The platform is based on CWT's CST design with some improvements here and there to keep up with the modern requirements. The only thing missing is a 12+4 pin connector. Still, XPG informed me that they are already working on an updated version with this connector included and the other specifications that the new ATX12V v3.0 spec requires.
The XPG Cybercore 1000 might lose overall performance to the EVGA SuperNOVA 1000 P6 and the Asus Rog Thor 1000, but its build quality is even higher, and it uses a more modern platform than both of these units. Moreover, its Nidec fan sets the bar too high. The only thing missing is the 12+4 pin connector, so you should probably wait a bit for the upcoming version that will have it since it is a shame to buy a PSU now that won't be compatible with the upcoming GPUs.
This is not a problem only for the XPG Cybercore 1000 but for most current-generation PSUs. Thankfully Nvidia provided an adapter with its 3090 Ti, which uses three 6+2 PCIe connectors to power a single 12+4 pin connector, but this is not what the ATX spec v3.0 has in mind since the extra 4 pin connectors will be utilized in upcoming GPUs.
