INTRODUCTION

    Modern high‑performance systems place unprecedented demands on their power supplies, especially as GPUs and CPUs continue to push higher transient loads and sharper power excursions. This has shifted the PSU from a background component to a critical part of system stability, where electrical behavior under dynamic conditions matters just as much as raw wattage. ATX 3.1 and PCIe 5.1 have become the new baseline for next‑generation builds, defining stricter transient‑response requirements and introducing the 12V‑2x6 connector for safer, higher‑capacity GPU power delivery. The FV‑1200PM represents Formula V Line’s entry into the Platinum‑class ATX 3.1 and PCIe 5.1 space and that's obviously also what today's review is all about.

    Formula V Line is a Taiwanese company founded by a group of professionals in 2012. Our main product lines include various computer cases, power supplies and air-cooling systems for computers. Our research and development team can bring your best ideas to life. Formula V Line's mission is to create reliable products with the best price-quality ratio.

    The FV PM line of power supply units currently includes three output variants (850/1000/1200W) available in both black and white colors. The 1200W output model which I have here with me today is ATX 3.1 & PCIe 5.1 compliant and 80 PLUS Platinum certified (up to 92% efficiency) and features a single 12V-2x6 power connector, four 6+2 pin PCIe power connectors, single +12V rail (100A) capable of delivering 100% of the units’ power output (1200W) and has a total power output of no less than 1348W (peak should be up to 2700W for up to 100ms - once again however this is not something I can test). The FV-1200PM also features a half-bridge & LLC Resonant Converter with DC to DC design, active PFC, zero fan mode for its 120mm fan (starts spinning after 40% load), high-quality Japanese capacitors certified for use up to 105 degrees Celsius and a full array of electrical protections including over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP), surge and in-rush (SIP), no-load operation (NLO) and over-power (OPP). As for warranty Formula V Line covers the entire FV PM line of PSUs with a 10-year limited one.

SPECIFICATIONS AND FEATURES

PACKAGING AND CONTENTS

A partial product picture is placed at the front of the box along with the company logo and the main product features.

The electrical tables of all three available models are printed at the rear.

Typically, the unit is wrapped inside a synthetic cover and placed between two pieces of foam.

Along with the FV-1200PM, its power cord and modular cables inside the box you'll also find 4 zip ties, 4 mounting screws and the user manual.

THE FV-1200PM EXTERIOR

All modular cables feature individually sleeved cables, including the 12V-2x6 cable.

Measuring just 140mm in width, 150mm in length and 86mm in height the FV-1200PM is a compact model.

Formula V Line has chosen to use an 120mm fan with this model.

The company logo is printed on both sides.

As usual the electrical table is printed on a sticker located at the base of the enclosure.

All 12 modular power ports are tagged.

At the rear of the unit, we find the on/off and hybrid fan switches and the power port.

THE FV-1200PM INTERIOR

Formula V Line has removed the name of the fan manufacturer so I don't know its specifications.

The OEM behind the FV-1200PM is Dongguan Sanren (SANR).

Primary capacitors are manufactured by Rubycon and are certified for use up to 105 degrees Celsius.

Secondary capacitors are manufactured by Nippon Chemi-Con and Rubycon and are again certified for use up to 105 degrees Celsius.

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

    As the review comes to a close, the Formula V Line FV‑1200PM proves itself to be a well‑rounded Platinum‑class option with clear strengths. It delivers very good rail stability, relatively low noise levels, and a compact footprint that makes installation easier than many competing 1200W units. Its 80 PLUS Platinum efficiency keeps thermals and power waste low, reinforcing the PSU’s overall refinement. The drawbacks are modest but worth noting, SANR isn’t the most established OEM (somewhat popular lately however), the single 12V‑2x6 connector limits flexibility for future GPU configurations, and the model’s very low availability makes it harder to source. Even so, the FV‑1200PM stands as a capable, efficient, and quiet ATX 3.1 & PCIe 5.1 unit.

    Even though like many other models by Formula V Line the FV-1200PM 80 PLUS Platinum power supply unit is not widely available it does retail around the world for around USD160/160Euros and so it’s priced well, more or less. Availability and cost aside the FV-1200PM performs very well, does so without its 120mm fan becoming annoying and is covered by a 10-year limited warranty so the Golden Award is in order.
