Deepcool PX1200G 1200W ATX 3.0 PSU Review

 Deepcool PX1200G - Is it indeed the best value for money ATX 3.0 PSU out there?

With the Nvidia RTX 4000 cards storming the market and the PCIe 5.0 aka the 12VHPWR connector becoming a mandate with the RTX 4070Ti and above atleast at the the writing, the new ATX 3.0 PSU standard is becoming more and more mainstream with each passing day. Obviously there is no harm in using the older generation PSUs paired with the 16-pin to three or four 8-pin PCIe connector adapter that these cards come with but the plethora of benefits the new ATX 3.0 standard offers makes it a lucrative choice if the units are available at great prices.

Talking about prices, Deepcool has been a major player in the PSU market lately with its constantly high value for money PSUs coming in the market one after another. It was about time that they jumped into the ATX 3.0 mix and the latest Deepcool PX1200G that we have on the table today is a result of the same.

The Deepcool PX1200G is a 1200W 80+ Gold certified PSU meeting the stringent ATX 3.0 certification norms hence delivering high efficiency at less than 20% loads and obviously comes equipped with the 16-pin connector right out of the box.

What's in the Box?

The Deepcool PX1200G is manufactured by Channel Well Technology (CWT) and is a 80+ Gold unit delivering 1200W of pure power. It is ATX 3.0 certifies hence delivers 60% efficiency even at as low as 10W or 2% of the total wattage so no matter if you buy the 1200W model or the lower wattage variants like the 1000W or 850W lower load efficiency is guaranteed due to its ATX 3.0 certification.

The unit has compact dimensions, and the fan grille is not restricted, allowing for high airflow. On the front side, square ones are used instead of the typical honeycomb-style perforations. On the same side, besides the colored power switch, we also find a button for toggling on/off the PSU’s semi-passive mode.
Two EPS connectors on dedicated cables, three PCIe 6+2 pin on the same amount of cables, a single 12VHPWR set at 600W, eight SATA, and four 4-pin Molex connectors. Usually, 1200W PSUs have more than ten SATA connectors, but I find this extreme since most use NVMe drives nowadays, so eight SATA will be enough. The amount of 4-pin Molex connectors is adequate, and the distance between all peripheral connectors is ideal at 150mm.

What's Under the Hood?

Like mentioned earlier the unit is CWT made and is equipped with Nippo Chemi Con and Rubycon electrolytic capacitors both on the primary and secondary side and since these are rated at 105C so we do expect reliability and decent filtration capacity here.

This is the popular CSZ platform CWT provides, used in many high-capacity ATX v3.0 PSUs. The design uses analog controllers for all circuits. A half-bridge topology and an LLC resonant converter are on the primary side. The secondary side utilizes a synchronous rectification scheme with ten Infineon FETs generating the 12V rail and two VRMs for the minor rails.

The cooling fan is by Hong Hua and uses a fluid dynamic bearing for lower noise output and increased reliability. Lastly, the build quality is high; the same goes for the soldering quality. At the solder side of the PCB, CWT also enhanced some PCB traces with copper plates, for better conductivity and lower power losses, at high loads.

My Verdict

With the current scenario of ATX 3.0 PSU in the market, the Deepcool PX1200G is certainly offering a very solid package at a very lucrative price point of around ₹18.5K which is a not the cheapest one out there but considering the reputation of the CWT platform it employs here along with a thoughtful feature set like the hybrid fan system and a shorter over all design makes the Deepool PX1200G one of the best options in the market today if one is after a ATX 3.0 unit to power their shiny new RTX 4000 series card.

Cable connectors are ample in number with a very decent length that can cover the length and breadth of even the tallest cases out there. The hybrid fan might scare a few at first but the feature can always be switches off making it a great option for most people out there.

"The Deepcool PX1200G is a highly recommended unit offering reliable performance and cutting edge modern day features of an analogue PSU and should be on the shopping list of everyone looking to buy a 1200W PSU" 

Pro - 

  • Reliable OEM
