Thermaltake Toughpower Grand expanded the range with three new models, the design of which is based on the previously submitted blocks Toughpower DPS-G RGB power with fans equipped with RGB-backlit. New PSU Thermaltake Toughpower Grand RGB 750W Gold working with efficiency 80PLUS Gold, a fully modular cabling, there is a toggle, switching the fan controller in an active or semi-passive modes. In our test lab model received an average power of 750 W from the line Toughpower Grand RGB Gold.
Toughpower Grand line has long been topom Thermaltake, although submitted late blocks Toughpower DPS G RGB power shifted focus on themselves because of the excellent efficacy and software interface. However, the last point of interest is far from all users. Therefore Thermaltake unveiled blocks Toughpower Grand RGB power – the new Classic models without programming interface, which promise to improve quality and productivity. For the new line Toughpower Grand RGB claimed high-quality components, a 10-year manufacturer’s warranty, clean output voltage, 140-mm fan with integrated lighting and switched-mode. Note efficiency 80PLUS Gold, a fully modular cabling and four PCI Express connector – for the model with 750 Watts is quite a decent level.
The new lineup Toughpower Grand RGB certification 80PLUS Gold went three models ranging from 650 to 850 watts. In retail, they have not yet appeared, but the manufacturer indicates the recommended price of $ 89.99 (650 W), $ 99.99 (750 W) and $ 119.99 (850 W), so Toughpower Grand RGB surely attract the attention of buyers.
Thermaltake Toughpower Grand RGB 750W Gold comes in a cardboard box on which is printed the basic information about power supply, and the power supply is securely packed in a foam.
Supply Thermaltake Toughpower Grand RGB 750W Gold is quite expected. Also detachable power cables you get the power cord, mounting screws and cable tightening, as well as a quick start guide.
Thermaltake Toughpower Grand RGB 750W Gold is based on the “new” design that Thermaltake has implemented together with models of DPS G RGB. The basis was the body of sheet steel with coal-black color. Gilded ventilation grille characteristic of the Toughpower models remained in the past – it has replaced the perforated cap with a black oblong holes.
The new cap apparently stands out not so much, but let’s not forget that during the operation it is beautifully illuminated RGB-fan. On the other hand, a new grille with a standard body certainly allow manufacturers to reduce costs.
On the inside wall you can see the connectors for the modular cable connection.
Besides the two connectors 24P ATX cable, which is divided by the power supply, you can see the four 6-pin sockets for peripheral and SATA, as well as three 8-pin socket for the cable 12 V. The two red jacks are designed for cables PCI Express, as black – 8-pin CPU cable.
On the outer wall of the power supply on and besides the toggle socket mains cable can be noted two additional elements. The switch on the power jack allows you to switch the fan controller in an active or semi-passive mode. Under the power jack located button turns on / off the backlight.
Thermaltake Toughpower Grand RGB 750W Gold uses a line 12, which is available on almost all of the power supply unit. In Thermaltake Toughpower Grand RGB 750W Gold rated current of 62.5 A, corresponding to a power of 750 watts. In the secondary voltage, which also provides a line 12 through converters DC-DC, declared the current up to 22 A, the total capacity of up to 120 watts. Overall, performance for 750 watt quite decent.
Inside Thermaltake Toughpower Grand RGB 750W Gold set fairly compact printed circuit board, so the body could be made less. Thermaltake in this case to use the platform, different from the Toughpower DPS G RGB. We get a modern conversion topology with resonant LLC and DC-DC for the secondary voltages. Thermaltake is not saved on the components, electrolytic capacitors Nippon Chemicon used for secondary circuits. a capacitor with a capacity of 680 uF and 400 V is set in the main chain in the Japanese manufacturer Rubycon. Also, it can be seen, and solid capacitors for the secondary circuit.
Of course, a good power supply, all protection schemes should be implemented, as there has to risk all “iron”, established in the system. And Thermaltake Toughpower Grand RGB 750W Gold did not disappoint. The power supply has a protection against excessively high voltage (OVP), over current (OCP), overload (OPP), and short-circuit (SCP). Thermaltake indicates the security data in the manual, although the OCP is a not quite clear range, for example, “between 24.2 and 35.2 A” to the secondary voltages.
In our tests, we confirmed the presence of protection circuits against overload. In the secondary voltage 3.3V and 5V power supply is turned off when the current is increased to 28 or 30 A. On line 12 off threshold was 80 A, that fits into the range of 75 to 100 A, said Thermaltake. Here Thermaltake Toughpower Grand RGB 750W Gold showed their best side.
We proceed to estimate the noise level and equipment.
Thermaltake Toughpower Grand RGB 750W Gold uses a 140-mm fan, a special feature is the LED RGB ring in the fan housing. These fans Thermaltake releases yourself with the model TT-1425 number. According to Thermaltake, the fans are technically identical retail model “Riing RGB” and are based on hydrodynamic bearing (HDB).
Fan Controller Thermaltake Toughpower Grand RGB 750W Gold supports two modes which can be switched on a small toggle switch socket power supply from the mains. If support for a semi-Smart-Zero Fan mode turned off, the fan runs always active, the power supply is similar to the standard models. Smart-Zero Fan activation leads to a semi-operating mode in which the fan is not spinning at a load of up to 20%. When the load increases the fan starts to rotate. Interestingly, the threshold is determined by the rotation is loaded, rather than temperature. In our tests the threshold was even higher fan shifted to the active mode under a load of 200 W, that is, in the system idle PSU will operate passively.
Characteristics of the two modes are identical except that in a semi-fan does not rotate until a load of 20% (200 W in our tests). At low load the fan starts spinning at 570 rev / min, this speed it can withstand loads up to 60%. Fan Toughpower Grand RGB while running pleasantly quiet except in the immediate vicinity could hear the noise of the stream and the bearing. When the load to 80% increases the fan speed to 1000 rev / min, while it is relatively quiet, the noise level perceived weak. Under full load we get speeds of up to 1,250 rev / min, the noise of the fan becomes clearly noticeable.
The fan housing around the impeller installed RGB LED ring, the color of which can be arbitrarily choose from 256 colors. Location of the ring around the impeller, that is for the grille, gives an interesting volumetric effect. In general, the idea can be called a successful producer.
Since Toughpower Grand RGB no programming interface, unlike DPS G RGB, fan modes can be switched using the button under the power socket. User six modes available: red, green, blue, white, RGB changing colors and backlight off. Of course, in this case, the freedom of choice of 256 colors not unlike DPS G RGB model, but can be easily switched with the button.
Cables Toughpower Grand RGB 750W made with black plumes, as well as the main ATX cable. manufacture and quality of cable length can be called good. Four PCI Express power connector is quite sufficient for a 750-watt power supply, are available nine SATA power connectors and eight 4-pin Molex connectors for peripherals.
On interfaces Toughpower Grand RGB 750W Gold showed himself well pleased with the fan low noise and beautiful lighting.
After the announcement of the program 80 PLUS, the last 8 years at PSU market efficiency began to play an increasingly important role. The buyer got a pretty simple criterion to select – 80 PLUS, and the manufacturers have appeared convenient opportunity to differentiate their products through the certification level of efficiency. It’s nice to PSU efficiency that customers now receive several reasons justifying the purchase of a very good power supply. Let’s start with energy saving, which is reflected in the account of electricity, and if you are worried about the environment, you can slightly reduce the amount of combustion of fossil fuels and carbon dioxide emitted into the atmosphere. Also, smaller energy conversion loss leads to less heating power supply components. Finally, a more efficient power supply means more quality components and the latest technology. In any case, we performed quality control of the output voltage as a good power supply should not only work efficiently, but also stable.
Thanks to our test station we can fix the power consumed by the power supply from the wall outlet and power load (imaginary) of the computer that allows you to calculate the efficiency of power supplies. First we look at the effectiveness of different loads, and then move on to assess the effectiveness of a fixed load at three levels.
We measure the effectiveness of starting with a very small load-five per cent, which corresponds to more than 35 watts of power. However, this level is very small, power units under it are not optimized, so the efficiency is low. In Toughpower Grand RGB 750W we got a relatively good result of 81%. When you load ten percent efficiency increases to a decent 89.5%.
At 20% load test power supply left on the calculated efficiency. It was a good 92.4%. In the load range between 40 and 60% power supplies typically achieve maximum efficiency, in the case of 750-watt Thermaltake Toughpower Grand RGB we have a maximum of 93.5% at a load of 40%. The power supply could Thermaltake maintain efficiency under load of 30 to 60% at a level above 93%. After peaking at 40% load efficiency decreased slowly with the load of 60% and amounted to a decent 90.8% at full load. For PSU 80PLUS Gold results are very good.
For power supplies, we also had three dimensions, corresponding to the three 80 PLUS certification level (20%, 50%, 100% load) with mains supply 115 V / 60 Hz. The distribution of our test station load does not quite match that of 80PLUS in laboratories, but to use it for an exemplary comparison. In Thermaltake Toughpower Grand RGB 750W Gold we got the level of efficiency of 87% / 90% / 87%, which is above the minimum 91.3% / 91.7% / 88.1% required for 80PLUS Gold.
PSU Toughpower Grand RGB 750W demonstrates that 80PLUS rating does not reveal the whole picture of performance, because it refers only to the minimum efficiency. On the first point of load (20%) Toughpower Grand walked minimum bar 80PLUS Platinum by an impressive 1.3%. In the other two points of the PSU load did not reach Platinum strips 0.3 and 0.9 percent, respectively. As a result, we got 80PLUS Gold certification, which guarantees the customer a minimum efficiency. If under moderate to high load power supply unit Thermaltake Toughpower Grand RGB 750W Gold rating meets 80PLUS Gold, then at small loads it is not worse Platinum models. Therefore, when evaluating the power supplies necessary to look not only for certification, but also on the effectiveness of different loads.
Equally interesting it is to compare the efficacy in three fixed loads, because it allows to evaluate the efficiency of power units in terms as if they are set to the same configuration. The first load of 90 W corresponds to the old office PC or a modern computer average in idle mode. Thermaltake Toughpower Grand RGB 750W showed excellent efficiency of 90.9% among the 80PLUS Gold models, while he even walked some PSU 80PLUS Platinum, like Seasonic Snow Silent 750W or with In the Classic the Win the Series 750W . Interestingly, the Toughpower Grand RGB by two percentage points bypassed previously tested PSU Toughpower DPS G RGB 650W with Gold certification.
When the load increases up to 250 W power supply Toughpower Grand RGB 750W has shown good results. He walked visibly competitors with certification of 80PLUS Gold, coming up with two models of Platinum. At 500 watts the efficiency Toughpower Grand RGB 750W was also quite decent, although here he was rolled up to the level of other 80PLUS Gold models.
Equally interesting it is to compare the efficacy in three fixed loads, because it allows to evaluate the efficiency of power units in terms as if they are set to the same configuration. The first load of 90 W corresponds to the old office PC or a modern computer average in idle mode.
The quality of the output voltage is one of the most important criteria for the power supply, no less important than efficiency. The power supply must work stably, the voltage must not “jump”, otherwise it may affect your computer. So we checked the voltage levels at different loads, and evaluated whether they are within acceptable ranges ATX specifications. Recall that according to ATX specifications permitted deviation of plus / minus 5 percent of rated voltage, we just set the data threshold values on the charts as the boundary.
In addition, we evaluated the quality of the output voltage using oscilloscope. In particular, we evaluated the high frequency noise and ripple voltages that occur on the output lines of the DC. They are associated with the principle of pulse power supplies, and depending on the design and quality of power supply filters may be smoothed with varying degrees of success. ATX standard provides for a line of 12 allowable ripple 120 mV (peak to peak), and the lines for 3.3 V and 5 V – 50 mV (peak to peak).
Thermaltake Toughpower Grand RGB 750W Gold shows good results of stress stability for its class. In the secondary voltage drop was only 1.6% and 1.1%, respectively, throughout the load range. On line 12 the fall was slightly smaller – only 1.2% of the load of 10% to the total. In general, good results can be called, they are much lower than the permissible level.
We also got good results in ripple / noise. Thermaltake indicated that ripple / noise are less than 30 mV, but we got even lower level. Toughpower Grand RGB ripple showed up to 10 or 13 mV on lines 3,5 and 5, and only 13 mV line 12 B.
The power supply unit Thermaltake Toughpower Grand 750W well proved itself on the quality of the output voltages. We got a fairly stable level of stress, the pulsations and noise complaints either.
Thermaltake Toughpower Grand RGB 750W Gold – an interesting power supply. In our test lab has already visited a representative range Toughpower DPS G, but Toughpower Grand RGB 750W was even better. Of course, he does not have the USB interface, but you also get a fan from the RGB-backlit display and switch between semi-passive and active fan operation modes.
Thermaltake Toughpower Grand 750W Gold in our tests showed a very good efficacy at low loads it can compete with the Platinum models. Since the power supply is perfect for those users whose computer most of the time idle or under office / 2D-loads. But even at medium to high loads, we have good efficiency 80PLUS Gold Level. Under load, the voltage is reduced moderately, ripple / noise are well below limits. Thermaltake has used high-quality Japanese capacitors, knowingly manufacturer gives ten years warranty
In terms Thermaltake Toughpower Grand RGB 750W Gold noise does not set new records, but it works nicely quiet. At low load up to 20% in a semi-fan does not spin mode, the power supply works silently. By equipping Thermaltake also showed its best side: a fully modular cabling, and we liked the variety of interfaces, and the quality of cable manufacturing. The buyer will have four PCI Express connector and nine SATA, that the power of 750 watts is enough. In addition to adjusting the fan toggle mode on the external panel present the mode button Fan RGB-illumination. Of course, the lights – a matter of taste. If you do not like, then you can turn off the backlight.
If you are willing to part with the support of the program, the Toughpower Grand 750W Gold is preferable Toughpower DPS G RGB 750W. Yet Grand power supplies are cheaper, but at the same time provide a higher level of performance on key parameters, including higher efficiency and better output voltage.
Thermaltake Toughpower Grand RGB 750W Gold provides a balanced set of features, and the fan from the RGB-backlit many like it.
