Native PCIe 5.0 is more secure!Cooler Extreme GX1250 GOLD Power Supply Review: Full Load Voltage Deviation

1. Preface: 1250W high power, native support for PCIe 5.0

Six years ago, a high-end computer with i7-7700K + GTX 1080 Ti had a dual-baking power consumption of no more than 45W, which was more than enough with a 700W power supply.

Today, the power consumption of the i9-13900KS baking machine easily exceeds 330W, and the TGP of NVIDIA’s next-generation flagship RTX 4090 public version is as high as 450W, and various non-public 500W models abound. If you want to install a high-end computer, a 1000W rated power supply is the most basic requirement.

Of course, if you have other needs, such as a large number of RGB fans, high-end water cooling, enterprise-level SSD, etc., the 1000W power supply is also somewhat stretched.

Recently, Cooler has updated its GX Gold product line. In addition to having higher power, it also supports PCIe 5.0 power supply.

This is the GX1250 GOLD power supply we received. It adopts a full module design and has passed the 80PLUS gold certification. Under typical load conditions, the conversion efficiency can reach 92~93%, which is close to the standard of 80PLUS platinum power supply.

In terms of workmanship, GX1250 GOLD adopts full-bridge LLC technology, with Japanese capacitors inside and a 140mm FDB fan. The noise at full load is less than 30 decibels. When the load is lower than 40% (500W), it will stop intelligently.

Of course, the biggest feature of this power supply is that it supports PCIe 5.0 power supply natively.Provides +12VHPWR interface and power supply line, no need for adapter cables, and +12VHPWR output power up to 600W, don’t worry about RTX 4090, even the future RTX 6090.
