The Ultra Products X4 500W PSU is a solid piece of kit in a nice tidy package. This PSU comes with a 32A +12v rail and only provides 2x PCIe connectors. It is completely modular and features a nice large fan that provides very good cooling to this unit under normal circumstances. When pulling 550W through this unit some components hit 50°C as measured with an IR Thermal probe, but we experienced no stability issues. . .
