DeepCool PX1200G ATX 3.0 Gold Power Supply Review

There are a lot of great PSUs hitting the market recently, what with the recent-ish switch up to the latest PCI Gen 5.0 and ATX 3.0 standards, and with newer CPUs and GPUs using a huge amount of power, we’re seeing 1000W+ PSU become the norm again. The latest unit from DeepCool ticks all of these boxes, with the latest standards, and a plentiful 1200W output, making it well-suited for any high-end gaming PC or workstation.

Silverstone DA1200R Gold

There’s no silly RGB here or anything like that, it’s just designed to be a powerful power supply that isn’t going to break the bank. It’s built to handle big power spikes, with an increased hold-up time, and also features the latest PCIe Gen 5 12VHPWR connector to support the latest Nvidia GPUs, and likely many future models, without the need for those awful PSU adaptors. There’s also 80 Plus Gold Efficiency, and a switchable hybrid and active fan mode.


  • ATX 3.0 Power Supply: The DeepCool PX1200G is a newly designed power supply that meets the latest ATX 3.0 standard. With a dedicated 12VHPWR, 2 EPS, and 3 PCI-e ports, the PX1200G provides stable power for a wide range of components.
  • The Past, Present, and Future: With the ability to provide three times the total GPU and twice the total system power for 0.1 ms, power spikes will never be an issue. The PX1200G will provide stable and consistent power to traditional and next-generation PCs.
  • Reliable Stability: Through the use of a dual main capacitor topology, the PX1200G can keep the hold-up time to ≥ 16ms under full load.
  • PCI-E 5.0 Power Supply Perfected: Equipped with the new PCI-e Gen 5.0 12VHPWR cable, the PX-G provides up to 600W for power-hungry GPUS.
  • Static to dynamic: The PX1200G comes equipped with the option to switch into semi-fanless operation. In hybrid mode, the 135mm FDB fan will dynamically adjust out of its zero RPM state once the system load hits a certain threshold.
  • The glory of gold: 80 Plus Gold certified to ensure 90% efficiency under typical load conditions.

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
