Thermaltake Toughpower DPS G RGB 750W Gold Review and test power supply

Toughpower series has long been headed by a production line Thermaltake PSUs. Of course, it is updated periodically, but often the old and new models have very similar marketing name, so when you buy a particular device to be careful not to rely only on the marketing name or the photo image on the page of the product in the store. It is necessary to compare the part number of the acquired product and the required modifications PSU (part number can be found on the manufacturer’s website), as sales are simultaneously present the new and the old product line. For example, a precursor Thermaltake Toughpower DPS G RGB 750W Gold / Titanium products are power supplies Toughpower DPS-G, which still can be found on sale, that makes some confusion, especially if the person is not aware of these features of Thermaltake products.

It is worth noting that the model 850 W groups present in both the new product – and Thermaltake Toughpower DPS G RGB 750W Gold, and Toughpower DPS-G RGB Titanium, which also adds to the convenience in a series of navigation.

Toughpower DPS G RGB 850W Titanium – the world’s first such power supply unit with patented annular illumination of the fan, which is able to use the 256-color palette. Like all other PSU in this series, it is equipped with the PC-Off remote control, which is available after you install the software on a Windows computer, and use a smartphone or cloud service as a remote control.

What we will now meet with the power supply 750 Watt – Thermaltake Toughpower DPS G RGB 750W Gold, which occupies a central position in the group between the aforementioned Toughpower DPS-G RGB Gold 850, and the youngest at any given time model Toughpower DPS-G RGB Gold 650 .

Thermaltake Toughpower DPS G RGB 750W Gold: Packing

Thermaltake Toughpower DPS G RGB 750W Gold is a cardboard box with sufficient strength matte printing industry.They are decorated in shades of black and yellow colors.

body length is about 160 mm, additionally you will need at least 15 mm for the supply wires to the power supply, so the installation should not rely on the installation size of the order of 180 mm.

In the external design of the power supply draws attention stamped grille above the fan. Not very clear what guided developers setting grating with such a high flow resistance, as it is clear at a glance that the effective working surface in such a lattice is less than half of its total area. Perhaps the technical parameters were simply born for the sake of design.

Important feature is the availability of power supplies series Toughpower DPS G RGB Gold / Titanium hardware and software for monitoring and management of complex SPM 2.0, which allows you to control the voltage, current and power of the channels 3,3, 5, and 12 volts, track separately for power supply lines CPU and the video subsystem and monitor certain parameters of other subsystems, including temperature, due to the software component SPM 2.0.

If power units using the first version of the software and hardware the SPM, used a proprietary four-pin connector to connect the control unit and monitor to the computer, then the second version has been used for a standard connector Micro-USB, and the kit includes a cable for connecting to the inner block system board with 10 (9) pin connector, which is much more versatile and convenient.

Modes PSU cooling systems are switched solely by a software shell, t. E. Hybrid mode can only be enabled by installing proprietary utility for Windows. Also, only through the software available backlight control system, which has two main modes: manual and automatic. In manual mode, the desired hue can be selected using the interface, and the system automatically implements dynamic backlight control algorithm.

Mobile version of the utility company to remotely reboot or turn it off if necessary.

Thermaltake Toughpower DPS G RGB 750W Gold: Characteristics

All necessary parameters are indicated on the power supply enclosure in full, for the + 12VDC bus power stated value of 744 watts. power ratio of the bus + 12VDC and full capacity is 0,992, which is a great indicator.

Thermaltake Toughpower DPS G RGB 750W Gold: length of the wires and the number of connectors

Without exception, all the wires are modular, that is, they can be removed, leaving only those that are needed for a particular system.

The number of connectors is quite sufficient for the average level of the system unit, but given the declared capacity and positioning of this model we would like to see more connectors SATA Power – about 9-12 pieces 3-4 cords, as is done, for example, the power supply unit Thermaltake Ural 650W . But the number of peripheral connectors is clearly redundant: two complete cable with four connectors of this type in each. Why do they need today in such numbers – remains a mystery. Instead of one of these strings would be to add a third SATA Power cord with connectors, which would make a set of connectors is much more balanced and relevant product capacity.

The cable length is sufficient for comfortable use in buildings full tower size and more overall overhead power supply. In buildings up to 55 cm with nizhneraspolozhennym power supply wiring length should also be sufficient:. To CPU power connector – about 60 cm Thus, with the majority of modern buildings should be no problems. But in the case of very dimensional enclosure size full tower (or more) wire length CPU power connector may be insufficient.

Thermaltake Toughpower DPS G RGB 750W Gold: Cooling system

Semiconductor components of high-voltage circuits are placed on a compact radiator. Synchronous rectifier elements are arranged on a daughter board installed vertically. Switching power converters based on power constant voltage DC + 3.3VDC and + 5VDC located on another daughter board and additional heatsink does not have that active cooling is quite typical for the PSU. It is obvious that the developers have tried to design a device based on a convection cooling radiators and elements and their deprived.

The power supply capacitors are installed mainly brand Nippon Chemi-Con, as well as a large number of polymer capacitors.

Fan installed in Thermaltake Toughpower DPS G RGB 750W Gold, is branded by the Thermaltake, however, it is available and labeling of the manufacturer. In this case we have a product of Hong Sheng – A1425L12S. Find the model for the label on the manufacturer’s website we could not, but we can add that the company Thermaltake claims the use of hydrodynamic bearings in the fan of the power supply. Presumably this nominal speed of the fan is 1000 rpm.

Thermaltake Toughpower DPS G RGB 750W Gold: Testing power supply

The first step is to test operation at maximum power supply unit for a long time.This test allows you to confidently ensure PSU efficiency.

The power supply unit without any problems coped with the long-term work at maximum capacity. The disadvantage is the low loading capacity of only channel + 3.3VDC and as a consequence, a significant deviation of the voltage on the channel at a relatively high power load.

The next step is to build a tool krossnagruzochnoy test characteristics (tures)and presenting it on chetvertploskosti limited maximum power bus 3,3 & 5 on one side (on the ordinate) and the maximum capacity of the bus 12 on the other side – on the horizontal axis. At each point of the measured voltage is indicated by a color marker, depending on the deviation from the nominal value.

It is necessary to clarify that in the presence of abnormalities within three percent of the power supply parameters can be considered to be at a good level.

Tures allows us to determine what level of load can be considered acceptable, especially on the channel + 12VDC, for the test specimen. However, the deviation of the current value of the nominal voltage on the channel + 12VDC not exceed three percent of the entire power range, which is a very good result.

In a typical power distribution through channels, typical modern home computer systems, deviations from the nominal channel + 5VDC not exceed two per cent and + 3.3VDC – four percent. This is quite a decent result.

The next test is intended to determine the maximum power that can be fed through the appropriate connectors at the specified deviation voltage of 3 or 5 per cent of the nominal value.

In the case of a single graphics card power connector maximum power channel + 12VDC is not less than 150 W at a deviation of 3%.

Thermaltake Toughpower DPS G RGB 750W Gold Review and test power supply

In the case of graphics cards with two power connectors for maximum power channel + 12VDC is not less than 250 W at a deviation within 3%, which allows the use of powerful enough graphics card of GeForce GTX 980 Ti.

In the case of all four video card power connectors for maximum power channel + 12VDC is not less than 500 W at a deviation within 3%, which allows the use of a system with two powerful graphics card of GeForce GTX 980 Ti.

If the motherboard maximum power channel + 12VDC is not less than 150 W at a deviation of 3%. Since the board itself consumes within the channel 10 W, the high power may be required to supply expansion cards – for example, for cards without the additional power connector, which typically have a consumption within 75 watts. So that there will be enough power value obtained with a decent margin.

In the case of the maximum power of the processor on the channel + 12VDC is not less than 150 W at a deviation within 3%, which allows the use of almost any desktop processor socket Socket LGA1150 / 51 or even Socket LGA2011-3, including overclocking, as there is a practical high load capacity tires + 12VDC.

During the next stage of testing, we measure the parameters of the AC power supply, which is connected to the monitoring unit power at the latest at a constant power. Based on these data calculated parameters determining the efficiency and effectiveness of power supply.

At maximum power the power supply dissipates approximately 126 watts, 100 watts, he scatters at a power of about 620 watts, and 60 watts – to the power of about 380 watts, high efficiency is difficult to call, but it is quite good.

Regarding work lightly loaded and unloaded conditions, the inactive mode power supply itself consumes less than 0.5 watts, and in an active mode – about 5.2 watts. This is a good result.

PSU Efficiency is at a fairly average level. According to our measurements, the efficiency of the power supply reaches a value exceeding 85% in the power range from 200 to 750 watts, the maximum recorded value was about 86.6% at a power of 500 watts. At the same time, the efficiency at a power of 50 W was about 71.7%.

Thermaltake Toughpower DPS G RGB 750W Gold: Noise measurement

In preparing this material, we used the noise level measurement technique of power supply, which is still has the status of experimental. The power supply unit is located on a flat surface of the fan up on it at a distance of 0.35 meters placed measuring the sound level meter microphone Octave 110A-Eco, which is measured, and the noise level. The load power supply is carried out using a special stand, which has a silent mode.During the noise measurement is carried out at a constant current power supply operation for 20 minutes, after which the produced noise measurement.

A similar distance to the measurement object is closest to the table placing the system unit with installed power supply. This method allows to assess the level of power supply noise in harsh conditions in terms of the short distance from the noise source to the user. By increasing the distance to the noise source and the appearance of additional obstacles, having a good sound-reflecting ability, the noise level at the control point will also decrease, leading to improvement in the overall acoustic ergonomics.

When working in a range of up to 350 W power supply unit inclusive of noise is very low – in the range of 25 dBA at a distance of 0.35 meters. Spotting a source with noise at night it is possible unless with a small (less than a meter) range, and only if, especially listening, and turning off all other appliances and close the windows.

When operating at a power level of 500 watts this model noise approaching srednetipichnomu value in PD location in the near field. At greater distances the power supply unit and placing it under the table in the body with bottom location of PD such noise can be interpreted as being below average. During daylight hours, in a residential area with a similar source of noise will not be too noticeable, especially from a distance of a meter or more, and the more it will be barely noticeable in the office building as background noise in offices are usually higher than in a residential area. At night, a source with the noise level will be clearly visible, close it will be difficult to sleep. Such noise can be considered comfortable when working at the computer.

When operating at a power of 750 W noise level exceeds 40 dB, that is, is very high.

Thus, from the viewpoint of ergonomics, this acoustic model provides the relative comfort of the output power in the range of 500 W, and when load power of 350 W and less noise can be assumed very low.

We also commend the electronics noise power supply, because in some cases it is the source of unwanted overtones. This phase of testing is carried out by determining the difference between the noise level in our laboratory with the power on and off the unit. If the value obtained is within 5 dB, no abnormalities in the acoustic properties of BP no. With a difference of more than 10 dBA, as a rule, there are some defects that can be heard from a distance of about half a meter.

At this stage, measuring the sound level meter microphone is located at a distance of about 40 mm from the upper plane of the PSU, as at large distances electronics noise measurement is very difficult. The measurement is performed in two modes: the standby mode (STB, or Stand by) during operation load on the BS, but with the fan forcibly stopped.

In this case, electronic noise is minimal, the main contribution to the overall noise level of the power supply makes working fan.

Thermaltake Toughpower DPS G RGB 750W Gold: Thermal conditions

At 750 watts power capacitors temperature operation can be considered unsatisfactory, as the temperature exceeds the design value of 75 degrees. In the range from 350 to 500 watts are thermally loaded capacitors at a satisfactory level, and in the range up to 350 watts can be thermally loaded conventionally considered low.

Thermaltake Toughpower DPS G RGB 750W Gold: Operation at elevated temperature

At the final stage of tests, we decided to check the power operation at elevated ambient temperature, which was 40 degrees Celsius. During this testing phase, the heating is room for about 8 cubic meters in volume, and then the measurement of the temperature of the capacitors and the power supply noise in two denominations: the maximum power on the PSU and power of 125 watts.

Thermaltake Toughpower DPS G RGB 750W Gold demonstrated stable operation at maximum power and at elevated to 40 degrees ambient temperature. At ambient temperature increase power supply reacted minimal increase in the noise level and the marked increase in the temperature of the capacitors, which indicates the absence of cooling system performance reserve (or it is too “soft” mode).

Thermaltake Toughpower DPS G RGB 750W Gold: Evaluation of consumer qualities

Consumer quality Thermaltake Toughpower DPS G RGB 750W Gold are at a high enough level. This is facilitated by the low level of noise over a wide power range, low voltage deviation from the nominal value for a typical power distribution through channels, typical modern home computer systems, as well as high load capacity practical Canal + 12VDC. The disadvantages are not too high and the economy is not the most convenient set of connectors. BP also advantages include the availability of hardware and software for monitoring the power supply status.

Thermaltake Toughpower DPS G RGB 750W Gold: Conclusion

As with any product, this model is not without its flaws – small and not very much. We begin with a relatively high thermally loaded at the maximum, and it is close to capacity, but also in modes with high ambient temperatures. The noise level at maximum power is too high for home use. Also, do not overlook the low load capacity channel + 3.3VDC. But serious problems have Thermaltake Toughpower DPS G RGB 750W Gold is not, so for home use in the non-extreme systems, this model is well suited. Of course, a top representative of the series main issue is the durability of the pow.
