Тест и обзор: Corsair RM Series (2019) — обновленные блоки питания 80 PLUS Gold для массового рынка

Страница 1: Тест и обзор: Corsair RM Series (2019) — обновленные блоки питания 80 PLUS Gold для массового рынка

Corsair на выставке Computex 2019 представила обновленные версии популярной линейки RM для массового рынка. Линейка Corsair RM Series имеет сертификацию 80 PLUS Gold, предлагает полностью модульное подключение кабелей и полупассивный контроллер вентиляторов. Так что покупатель получает доступную, но в то же время весьма функциональную альтернативу high-end блокам питания Corsair. В нашу тестовую лабораторию поступили три блока питания на 650 Вт (CP-9020194-EU), 750 Вт (CP-9020194-EU) и 850 Вт (CP-9020196-EU). Посмотрим, как они покажут себя на практике.

Линейка RM Series от Corsair была представлена в 2013 году, она получила сертификацию 80 PLUS Gold и хорошее соотношение цена/качество. Но за последние три года они исчезли из розничной продажи, так что настало подходящее время для восстановления позиций линейки RM Series на рынке. Corsair как раз выпустила обновленные модели после прошлогоднего обновления RMx Series.

В общей сложности, в ассортименте Corsair вновь присутствуют три линейки для массового рынка с обозначением «RM» в названии. Все они предлагают сертификацию 80 PLUS Gold и полностью модульное подключение кабелей. Линейка RMi Series располагается выше остальных, она оснащена самыми высококачественными компонентами и цифровым интерфейсом Corsair Link. В случае RMx Series цифрового интерфейса уже нет, зато конденсаторы тоже используются «японских производителей». Наконец, третьей по счету идет обычная линейка RM Series тоже с качественными конденсаторами, но уже не японских брендов.

Линейка RM Series состоит из трех моделей мощностью 650, 750 и 850 Вт. За исключением разной мощности и набора интерфейсов питания, все три БП дают одинаковый набор функций. Отметим полностью модульное подключение кабелей, полупассивный контроллер вентилятора и гарантию производителя в 10 лет.

Кроме улучшения в некоторых деталях, Corsair повысила эффективность при малых нагрузках. Еще одна инновация в том, что новые блоки питания RM поддерживают режим «Modern Standby» под Windows 10, который пока используется только в ультрабуках, но с грядущими платформами Intel он распространится и на настольные ПК. Corsair не стала поднимать эффективность новых блоков питания RM Series, ограничившись вполне приличным уровнем 80 Plus Gold.

На российском рынке новые блоки питания еще не появились, в Европе Corsair выставила вполне разумные цены. RM750 (2019) можно приобрести за €105 (7.500 ₽), в России RM750x обойдется от 7.800 ₽, а RM750i — от 8.800 ₽. Разница в рекомендованной цене между моделями RM Series с разной мощностью составляет €10. Опять же, до появления БП в российской рознице какие-либо выводы о цене в рублях сделать сложно.

Конкурентами RM750 можно назвать Seasonic Focus Plus Gold 750W (от 9.100 ₽) и be quiet! Straight Power 11 750W (от 8.600 ₽), хотя в России они стоят заметно дороже, сравнимо со старшим RM750i. В ассортименте Corsair есть и менее дорогая альтернатива Vengeance V650M (от 6.500 ₽), если японские конденсаторы вам важнее полностью модульного подключения кабелей и официальной сертификации 80 PLUS Gold.

Legendary Performance and Reliability

Quiet operation at low loads, modular cabling and 80 PLUS® Gold efficiency makes HX Series PSUs a great choice for high-performance PCs.

Quiet operation at low loads

Basic PC power supplies have fans that spin whenever your PC is on – whether you’re pushing your graphics card to the limit or just surfing the web. HX Series power supplies are smarter than that: they generate less heat, so they require less cooling, and the thermally controlled fan only spins when it’s needed.

Slay the cable kraken

The modular cable set allows you to use only the cables you need for your particular set of components. There’s no more unwieldy mythical tentacled monstrosity of unused cables to clutter up the inside of your case.

High efficiency for lower energy consumption and less heat generation

Efficiency is the measurement of how well a power supply converts the AC power from your outlet to the DC power used by your PC’s components. If your power supply isn’t efficient, it will generate more heat, which requires more cooling and more fan noise. And, it might even affect your power bill.

HX Series PSUs are among the most efficient on the market. They help keep your PC cool and quiet, and your power bill down.

Understanding the Corsair AXi Series Digital Power Supplies

Replacing commonly used ICs with a digital signal processor in the Corsair AXi Series PSUs has many benefits. Today, I’m going to explain the functions of the components that are replaced within the Corsair Digital power supplies and how these changes benefit the end user.

Understanding the Corsair AXi Series Digital Power Supplies

The parts of the Corsair AXi Digital Power Supply that makes them unique when compared to other desktop power supplies is the absence of a PFC/PWM controller IC (integrated circuit) on the power supply’s primary side and a supervisor IC on the power supply’s secondary side. Both of these parts have been replaced with DSP, which stands for «Digital Signal Processor».

AXi PSUs still use what’s called a «resonant mode» topology like a lot of modern day super-efficient power supplies, but typically in other resonant mode PSUs a PWM controller IC changes the power supply’s switching frequency based on an analog signal derived from the load measured at the transformer. This makes the power supply more efficient at a wider range of loads compared to other power supply topologies, but doing this alone can affect ripple and noise and voltage regulation.

Understanding the Corsair AXi Series Digital Power Supplies

The resonant mode controller, shown above, is just about the only IC you’ll find in an AXi power supply that you may also see in other high end power supplies.

The supervisor IC is the heart of the power supply’s safety functions. Functions like OCP (over current protection, which is protection from any one output drawing too much current), OPP (over-power protection, which prevents overloading), OVP (over-voltage protection, which measures if voltage goes too high), UVP (under-voltage protection), and SCP (short circuit protection). Temperatures are also measured within the power supply and this is reported to the IC’s OTP (over-temperature protection). If any value programmed into the IC is exceeded, the IC is instructed to shut down the power supply.

Understanding the Corsair AXi Series Digital Power Supplies
Above is a supervisor IC found in a Corsair GS800 power supply.

In an effort to improve voltage regulation (drops in voltage as loads increase), the information concerning the power supply’s output voltage is sent back to the PWM controller via an analog signal. This information moves relatively slow when compared to the ever-varying loads of your typical PC, so voltage regulation is still not as good as it can be.

Understanding the Corsair AXi Series Digital Power Supplies

Above is the PWM/PFC controller from a Corsair GS800 power supply.

AXi power supplies improve on this analog system by using the DSP. Like a supervisor IC, the DSP measures all of the pertinent information on the secondary side, as well as taking the same measurements on the primary side as your typical PFC/PWM controller IC. This information is also analyzed by the DSP’s microprocessor and adjustments are made to the different components of the power supply in an effort to improve efficiency while maintaining very tight voltage regulation and minimizing ripple and noise. Because the signals are digital instead of analog and an inherently homogeneous DSP system is used to analyze the information as opposed to multiple ICs, adjustments can be made much faster than can be made with the typical set of ICs found in other desktop power supplies. And since the DSP is analyzing all of the same outputs (and then some!), the DSP still has the ability to act as a supervisor IC and shut down the power supply if any values exceed what is considered «safe» for the power supply or your computer.

Understanding the Corsair AXi Series Digital Power Supplies
Here is an AX860i removed from the housing. This one PCB has all of the chips that are part of the DSP system.

Let’s zoom in on some of the chips on this PCB. Shall we?

Understanding the Corsair AXi Series Digital Power Supplies

Above is a picture of the Freescale Digital Signal Controller found in the AXi series of power supplies. This chip handles what goes on on the primary side of the power supply.

This guy is responsible for the PFC (power factor correction) control, the PMW (pulse width modulation) control, monitoring of the AC input’s voltage, current and wattage and logical on/off control, like shutting down for inrush, brownouts, etc.

Understanding the Corsair AXi Series Digital Power Supplies

Above we see two more ICs found inside an AXi series power supply. The chip on the bottom is the main MCU, or «MCU I». The chip on the top is a USB MCU, or «MCU II». These guys handle what goes on on the secondary side of the power supply.

The MCU I does what we call «housekeeping». It has a lot of the same functions as a supervisor IC in an analog controlled PSU. Things like OCP, OPP, OVP, etc. are all monitored by this chip. This chip also handles the PMBus (power management bus) and thermal monitoring and fan control. The MCU I also monitors the power on (soft on/off) and power good signals coming from the motherboard. On top of all of this, the MCU I also monitors the DC output for voltage drop, ripple and noise and communicates back to the DSP to address any issues that may come up.

The MCU II is the chip that allows the user to turn on/off the single/multiple +12V rail capability of an AXi PSU via the Corsair Link software. The self test function is also controlled by this chip.

Since the DSP accumulates all of this information about the power supply, and does so in real time, we can deliver it to the end user via our Corsair Link software. Power supplies have attempted to deliver similar information about the power supply to the end user in the past; either via software or displayed on a 5.25″ bay LCD. But since the information about the power supply in these older units was accumulated via the PFC/PWM controller and supervisor IC, the information had to be converted to a digital signal before being displayed. This adds a good deal of cost and prevents the information from being delivered as close to real time as possible.

Understanding the Corsair AXi Series Digital Power Supplies

Using Corsair Link, we can monitor everything from AC input voltage, output wattage. even the current being delivered to each graphics card’s PCIe controller! Above you can see I’ve enabled OCP on each modular connector (essentially making the AXi a multiple +12V rail power supply) and turned all of the limits down to 20A.

We can also keep track of the temperature inside the power supply and how fast the fan is spinning:

Understanding the Corsair AXi Series Digital Power Supplies

All in all, AXi Digital Power Supplies are so much more than your average desktop PSU on so many levels. By utilizing a DSP, Corsair offers improved efficiency while maintaining stable voltage output and minimizing unwanted ripple and noise. And because all of this information is maintained in a digital format, and output to the Corsair Link software interface is practically seamless!

Using Link with a Corsair AXi Digital Power Supply

The Corsair AXi Series PSUs have a lot of premium features. They use a digital signal processor for better performance, they’re fully modular, and have a zero RPM fan mode at low loads. But one of the coolest things about the AXi power supplies, is their compatibility with the new Corsair Link software. Today, we take a look at the Corsair Link 2 software, or just «Link» for short, and more specifically how it gives you the ability to monitor AC input, DC output, the temperature and the fan speed of an AXi power supply.

The first thing I want to do is open up the «Graph» tab and set what I want to monitor in the «Config Panel» of this tab.

Using Link with a Corsair AXi Digital Power Supply

Above, you can see that I’ve checked boxes asking to have my two graphics cards’ temperatures and fans graphed, as well as my CPU’s temperature, the temperature of my AX860i power supply, as well as the AX860i’s fan speed. I’m also monitoring the temperature of the coolant in the Hydro Series H100 that is cooling the CPU and the RPMs of the two fans cooling the H100’s radiator.

Using Link with a Corsair AXi Digital Power Supply

While the system is idle, we can see that temperatures are relatively low. The AX860i is just barely over room temperature and therefore, the fan is not spinning.

Over on the «Power» tab, we see that the AX860i is only producing 107.3W as I sit here watching the Link software. It’s pulling 117.8W from the wall, so our efficiency is 91%.

On this tab, we can also monitor our voltages, including the voltage of our AC mains, as well as current for each of our +12V outputs.

There are also check boxes that allow you to turn OCP on for the 8-pin +12V outputs (labeled «PCIe») on the power supply. OCP stands for «over current protection» and will shut down the power supply if too much current is delivered on any of these outputs.

Finally, we see the AX860i’s temperature and the fan RPM on this tab. This is the same information we saw on the «Graph» tab, but in a different format. The fan is still not spinning because the temperatures are still low, but if we wanted to increase the airflow within our chassis just a bit, we can manually turn the fan speed up.

We start on the «System» tab.

On this tab, we can see everything that Corsair Link 2 monitors, but if we click on the «AX860i Fan» icon on the left, a configuration panel opens up on the right. By default, we can see the fan mode is set to «quiet» which means the fan isn’t going to spin at low loads. Changing this is easy.

Using Link with a Corsair AXi Digital Power Supply

The lowest setting is 40%, which equates to about 784 RPM. I can keep it like this and still not hear the fan. And the fan will still ramp up even faster automatically if needed. Let’s turn it up even more to find out where I can start hearing the fan.

At 76%, the fan is spinning 1508 RPM. I can definitely hear that now. Well, that’s enough of that. Let’s put the PSU fan back into «quiet» mode, fire up Prime95 and Furmark and see what kind of power we produce and let the fan spin up all on its own.

Using Link with a Corsair AXi Digital Power Supply

Almost immediately, the temperatures of the CPU and graphics cards increase. Under this load, we start to see the power supply fan ramp up as well.

Using Link with a Corsair AXi Digital Power Supply

After some time under load, we see our temperatures level out, an increase in the graphics cards’ fan’s RPMs and the PSU’s fan leveling off just over 500 RPM.

Using Link with a Corsair AXi Digital Power Supply

When we switch back over to the «Power» tab, we can see that our load has increased to 473.4W. We’re now pulling 502.9W from the wall and our efficiency is increased to 94%. We can see that the amperage delivered on all of our +12V connectors has increased, the AX860i’s temperature has increased very slightly, from 26.5 to 28.8°C, and the fan is now spinning at 556 RPM.

Of course, when you’re gaming you’re probably not going to be able to watch your load, temperatures and fan speeds while you’re playing. For this reason, Corsair Link allows you to log whatever information you’d like to keep track of in a CSV file. Simply check the boxes of the components you want to monitor, browse to where you want to save the file and give the file a name and click «start logging».

Corsair Professional Series HX1050 Review

Introduction

We would like to thank Corsair for supplying the review sample.

The Professional HX series used to be Corsair’s flagship of PSU products, until the AX series was launched. The main differences between HX and AX series are the different OEMs, the first are built by CWT while the second by Flextronics (AX1200) and Seasonic (AX850, AX750), the efficiency rating (HX:Silver, AX:Gold) and the used cabling design, the HX models utilize a semi-modular cable design while all three AX PSUs are fully modular.

Only recently, at Computex 2011, Corsair introduced the new HX1050. We suspect that the main reason behind the release of this model was that Corsair had a gap in this wattage range. To be more exact, the AX series does not include a 1000W PSU, the HX1000W counted many years in production and the competition was getting very rough. So a new PSU at this wattage range was urgently needed to enrich Corsair’s arsenal.

The HX1050 shares the same OEM with the older HX1000W although the used platform is completely different. The capacity of the successor is increased by 50W and efficiency remained at the same level, 80 Plus Silver. The single +12V rail is able to deliver up to 87.5A at 50 °C, there are six PCIe connectors and two EPS ones, the warranty is the same with all Corsair’s high-end PSUs, seven years. If the price ends up being competitive then HX1050 is going to be very popular among enthusiasts that cannot afford the high price of AX1200.
