Unboxing, product images and scope of delivery
The packaging follows the typical design of the brand. It provides adequate protection, and the package is rich, including Velcro, cable ties, and mounting screws for mounting the PSU to the case. There is also an OC bracket with a switch and an OC jumper, both of which have the same function: they combine all 12-volt rails into one. This will help you prevent the system from rebooting under overclocked conditions.
The exterior design is beautiful, at least in my eyes, and the build quality is top notch. It would be nice if the fan’s protective grille was less restrictive, though. The same applies to the exhaust air grille. The dimensions of the device are large by today’s standards. Nevertheless, it easily fits into any ATX-compatible case.
The number of EPS, PCIe and SATA connectors is reasonable, but I can’t say the same for the 4-pin Molex connectors. There are only two, while most power supplies have four ports, especially in this power range. However, the question of whether you need them at all is difficult to answer. The cable length is satisfactory and the distance between the ports of the peripherals is good at 150 mm. Finally, the 12VHPWR cable is rated for 600W output power.
In tabular form, it reads like this:
| Modular Cables | ||||
| Description | Cable Count | Connector Count (Total) | Gauge | In Cable Capacitors |
|---|---|---|---|---|
| ATX connector 20+4 pin (600mm) | 1 | 1 | 18-22AWG | No |
| 4+4 pin EPS12V (700mm) | 1 | 1 | 16AWG | No |
| 8-pin EPS12V (700mm) | 1 | 1 | 16AWG | No |
| 2x 6+2 pin PCIe (600mm) | 2 | 4 | 16AWG | No |
| 12+4 pin PCIe (600mm) (600W) | 1 | 1 | 16-28AWG | No |
| SATA (600mm+150mm+150mm) | 2 | 6 | 18AWG | No |
| SATA (600mm+150mm+150mm) | 1 | 4 | 18AWG | No |
| SATA (600mm+150mm) / 4-pin Molex (+150mm+150mm) | 1 | 2 / 2 | 18AWG | No |
| AC Power Cord (1330mm) – C13 coupler | 1 | 1 | 18AWG | – |
Protection circuits
The PSU did not shut down in any of the OCP tests I ran, so I’m skeptical about the official claims. I also measured low voltages at 12V3 and 12V4, so I can assume that this rail would drop below 11.4 V at higher loads. Nevertheless, this is allowed according to the ATX 3.0 specification, which allows up to 11.2 V. Also, the OCP on the slave rails is set high, especially at 3.3 V. On the contrary, the overvoltage protection is set conservatively, but I would like to see a lower limit at higher temperatures.
