INTRODUCTION

   After several months in the market ATX 3.0 & PCIe 5.0 compliant power supply units seem to have pretty much replaced their predecessors and even though the PCIe 6.0 standard is already a thing the simple truth is that these are more than enough to cover the needs of the market for many years to come. Yes, not every single company out there has updated their PSU lines to include ATX 3.0 & PCIe 5.0 compliant models but most as expected already have (so it's a safe bet that your favourite company already has at least one). DeepCool is one of the latest manufacturers to have one such product line and so today with me i have their PX1000G model.

   Established in 1996, DeepCool is a global brand in designing and manufacturing high-performance computer components for enthusiasts worldwide that includes CPU coolers, PC cases, Power Supplies, Peripherals, and more. With a strong background in independent research and development, DeepCool continues to provide high-quality products, premium customer service, and incredible value to our dedicated customers.

   The new PX line of fully modular ATX 3.0 & PCIe 5.0 power supply units is not only available in three capacities (850/1000/1200W) but also in two colors (black and white) thus allowing DeepCool to cover a larger segment of the global market compared to their competition. The entire line is 80 PLUS Gold certified (up to 90% electrical efficiency) and features active PFC and half bridge SRC LLC topology (DC to DC design), single strong +12V rail (83.3A) capable of outputting roughly 99.9% of the units’ total power output (999.6W) and a peak power output of 1238W (up to 2000W for 100ms according to ATX 3.0 specs – typically this is not something I can test however), secondary minor rails with a total output of 138.6W, 600W 12VHPWR PCIe cable, low profile (flat) cables, 3 PCIe 6+2 pin connectors, 135mm FDB (fluid dynamic bearing) fan with hybrid mode (zero RPM), 100% Japanese capacitors and an array of electrical protections including over-current (OCP), over-voltage (OVP), over-power (OPP), over-temperature (OTP), short-circuit (SCP) and under-voltage (UVP). Last but not least DeepCool covers the entire PX line of ATX 3.0 & PCIe 5.0 compliant power supply units with a very generous 10-year limited warranty.

SPECIFICATIONS AND FEATURES

PACKAGING AND CONTENTS

A product picture is placed at the front of the box along with the DeepCool and 80 PLUS Gold logos.

Two graphs showcasing efficiency and fan curves are placed at the rear along with the product specifications and the electrical table.

The PX1000G is wrapped inside a plastic bag and between two foam spacers while the modular cables are placed inside another cardboard box.

Along with the PX1000G and its power cable inside the box you'll also find the modular flat cables, 4 cable straps, 4 mounting screws, information paper, product manual and the user guide.

THE PX1000G EXTERIOR

Even the 12VHPWR modular cable that comes with the PX1000G is flat (low-profile).

Measuring 150mm in width, 160mm in length and 86mm in height the PX1000G is a medium sized unit.

The 135mm FDB fan has the company logo at its center and is placed beneath a large grille.

Just a small company logo is placed on both sides of the PX1000G.

As expected, the electrical table is placed on a sticker located at the belly of the unit.

The 11 modular connectors are located at the front (the 12VHPWR connector is different in color).

Turning the unit around we find the power port, on/off power switch (same color as the 12VHPWR connector), fan hybrid mode button and the usual honeycomb perforation.

THE PX1000G INTERIOR

The 135mm FDB fan is manufactured by Hong Hua and can reach speeds up to 2300RPM.

As with many other ATX 3.0 & PCIe 5.0 units the OEM manufacturer behind the PX1000G is no other than CWT (Channel Well Technologies).

For the two primary capacitors CWT has used nichicon ones rated for use up to 105 degrees Celsius.

Secondary capacitors are manufactured by both nichicon and Nippon Chemi-Con and are also certified for use up to 105 degrees.

TEST BED

TESTING METHODOLOGY

     Using a dedicated measurement instrument such as a Chroma or a SunMoon to test power supply units is without doubt the most ideal and accurate way (not to mention the fastest) to do that currently. However, it's certainly not the only way there is and so pretty much anyone can test a power supply unit just by using a test rig. Certainly, limitations do apply and so you can't really push a 1000W power supply to its limits if your system only uses 500W at peak loads and that's why over the years we saved certain hardware components for the purpose of building a dedicated PSU test rig. True it may not be as accurate as the above mentioned solutions but it comes really close and is in fact much closer to real world usage. So as always, we ran several games with maximum graphic options enabled at a resolution of 2560x1600 in order to stress every hardware component and increase the overall power demands of the system. The Passmark BurnIn Test was also used to overstress the components in an effort to provide the most accurate results possible. As a final test we also used the latest OCCT 4.4 software and its dedicated PSU testing suite since it can really bring a power supply to its knees after inside a few minutes.

   Rail stability was checked/measured with the CPUID Hardware monitor and a Metex multimeter which also recorded the system load in idle and in load. As always try to remember that the power consumption numbers listed in the graph are the highest (Peak) ones recorded during the entire duration of the tests and not the average ones. Noise levels coming from the fan were recorded using the high precision HD600 ExTech Sound dBA Meter from the rear of the unit and at a range of no more than 5-10cm. Readings under load are recorded the exact moment we manually switch the fans of all graphics cards from full speed to almost zero, that way the fan of the power supply does not have enough time to slow its RPM and so by doing this we get very accurate noise level readings. Needless to say, in order to get 100% accurate readings, you need to have a noise isolated room for that exact purpose, something which is quite impossible unless you are working inside a real lab (some people use very small noise insulated boxes but due to their size both heat and noise exceed normal levels and so the results can't really be considered to be 100% accurate, nor realistic for that matter). Also do take into account that since all noise measurements take place from just 5-10cm away the final noise levels to reach your ears will be considerably less.

* After well over 10 years of testing PSUs the Intel Core i7-920 CPU of this rig failed and so we replaced it with a Xeon X5660 (we also swapped the GA-X58A-UD7 for the G1. Assassin).

TEST RESULTS

CONCLUSION

   It’s been a very long time since I last had an PSU by DeepCool in the lab so the PX1000G was actually a very nice surprise. Of course, this is CWT and their units are renowned for their performance (well ok, not all of them) but still it’s nice to see more companies invest in their product lines by using well-established manufacturers. So, during all my tests performance was very good across the board and even though noise levels did get slightly high at maximum load (the fan didn’t however hit 2300RPM just like with other power supply units that use the same model – needless to say in hotter and cooler environments I do expect different results) once again do keep in mind two things, first that you shouldn’t get a power supply unit to use it at maximum output and second that all my noise level tests are recorded by just 5-10cm away.

   Currently retailing for just USD178.95 inside the USA (Amazon.com) and for 182.34Euros inside the EU (Amazon.de) the PX1000G ATX 3.0 & PCIe 5.0 compliant power supply unit by DeepCool is obviously priced relatively well. Overall, there’s nothing wrong with the PX1000G by DeepCool, yes, it might exceed noise levels a bit when maxed out but that shouldn’t mean much for people (far from easy to draw 1000W from any PSU) especially not when in terms of build quality and performance (not to mention availability in 2 colors) this is a very good unit and that’s also why it gets the Golden Award.
