INTRODUCTION

    Every PC build eventually comes down to trust, you can pair the fastest CPU with the most ambitious GPU, but none of it means anything if the power delivery behind them falters. The PSU is the one component that never gets to rest, it has to respond instantly to shifting loads, absorb the chaos of wall power, and keep every rail within safe margins no matter what the system throws at it. It’s here that build quality, component selection, and electrical design quietly determine whether your hardware enjoys a long, uneventful life or ends up dealing with instability, noise, or premature wear. As the market fills with units that promise high wattage but deliver mixed real‑world behavior, the importance of a PSU that prioritizes consistency over theatrics becomes even more apparent. Into that landscape steps the CPS PcCooler YT1200.

    Shenzhen Fluence Technology PLC, established in 2005, is mainly engaged in lithium battery cathode materials, new cooling devices for electronic products and LED industry chain-related businesses, which is recognized as a national high-tech enterprise.

    The YT line of power supply units but CPS PcCooler currently includes 850/1000/12000W output variants all of which are ATX 3.1 & PCIe 5.1 compliant and Cybenetics Platinum certified (up to 93%+ efficiency). Τhe YT1200 model features a single 12V-2x6 power connector, three 6+2 pin PCIe power connectors, single +12V rail (100A) capable of delivering 100% of the units’ power output and has a total power output of no less than 1319W (220% peak for this model which should place it up to 2.9KW for up to 16ms - once again however this is not something I can test). Other features and specifications include Full-Bridge & LLC Resonant Converter paired with synchronous rectification and DC‑to‑DC regulation (thus allowing the unit to sustain stable voltage output even under rapid load shifts), active PFC, Smart ECO fan mode for the 135mm fan (starts spinning after a specific load), flat embossed Cables and a full array of electrical protections including over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP), surge protection (SPD) and over-power (OPP). As for warranty CPS PcCooler covers their YT line of power supply units with a 10-year limited one.

SPECIFICATIONS AND FEATURES

PACKAGING AND CONTENTS

At the front of the box once again we find the company logo, product picture and available certifications.

Moving at the rear we find the unit’s electrical table, available power cables and the specifications table.

Typically, the unit is placed between two pieces of foam.

Along with the YT1200 power supply unit and its power cord inside the box you’ll also find 5 cable ties, 4 mounting screws, power tester, service & safety manual and the user manual.

THE YT1200 EXTERIOR

CPS PcCooler chose to go with low-profile (flat) embossed power cables.

Measuring 150mm in length, 150mm in width and 86mm in height the YT1200 is a compact high-output model.

The 135mm fluid dynamic bearing fan is placed underneath a nice-looking grille.

Just the company logo is placed on both sides.

Once again, the electrical table can be found on a large sticker located at the base of the unit.

All 11 power ports at the front of the YT1200 are tagged (12V-2x6 is also different in color).

At the rear we find the on/off power switch, ECO fan switch and the power port.

THE YT1200 INTERIOR

The YT1200 uses a 135mm FDM fan by Hong Hua rated for up to 2300RPM.

The OEM behind the CPS PCCooler YT1200 is the Taiwanese Andyson International.

Primary capacitors are manufactured by the Japanese nichicon and are certified for use up to 105 degrees Celsius.

Secondary capacitors are manufactured by Rubycon and Teapo (Taiwanese) 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 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

    What defines the CPS PcCooler YT1200 is its sense of electrical composure. The rails remain rock solid even when the system throws sudden, high‑demand spikes at it, and the internal build quality suggests a platform designed with longevity in mind. The capacitor mix (Japanese nichicon and Rubycon supplemented by Taiwanese Teapo units) is respectable, though not the all‑Japanese configuration some buyers might expect at this wattage. Under heavier workloads, the acoustic profile shifts noticeably, the fan curve climbs quickly once you pass the 700–800W threshold, making the PSU far more audible than it is at moderate draw. PcCooler’s choice to lean exclusively on Cybenetics certification, without the more familiar 80 PLUS badge alongside it, may also feel like an odd omission for buyers who value conventional validation. Still, the YT1200 delivers dependable power and solid engineering, with the main compromises being its assertive cooling strategy and a certification approach that won’t resonate with everyone.

    Availability is pretty much the single most important downside of the YT1200 by CPS PcCooler since I wasn’t able to find it anywhere, at least not in the USA or the EU. It’s recommended retail price however is set at USD159.99/159.99Euros and so if it does reach store shelves with that attached it will become the favorite of many. Cost aside the YT1200 delivers as advertised and even though its aggressive fan curves, Teapo capacitors and lack of 80 PLUS may be of concern for some people the Golden Award is still in order.
