Smart RGB 700 Watt is a power supply crafted for a guy who is looking to squeeze in a good PSU in his tight budget.

Previously We have reviewed Thermaltake Versa n26 way back, which is a fantastic chassis worthy of housing a beautiful PSU like this. Also, we reviewed Thermaltake TteSPORTS Level 10 M Advanced Gaming Mouse

This is a pocket-friendly PSU with 700 Watts which is fairly reasonable for one or two GPUs in running in the system. Let’s not overlook the important factor that PSU should never be taken lightly and one should always look for a good PSU unit despite its cost instead of avoiding the budget loss with cheap PSUs in your local market. A cheap PSU will surely bite you back with possible damage to your system components or, in the worst case scenario, end up burning your pc or even the house, well that is an endeavor you should be willing to face for a wooden house. So we should always give some respect to the “heart” of your CPU and tread wisely when choosing an appropriate PSU for your system.


Thermaltake Smart 700W 80+

Smart RGB 700 has an impressive efficiency with 80 Plus ratings and the wattage is pretty high, as most systems with one or two graphics cards take up 500 to 600 watts which may go further up depending on your components. Nonetheless, it provides a reasonable breathing space for your CPU. In the aesthetics department, they brought us a beautiful spectrum of RGB lights on the fans which you can toggle around with a button, the only downside is the absence of a connector to synch them with your CPU lighting system but it will definitely give you a mesmeric appearance with a well-shrouded casing.

Now, let’s have a look at the neat boxing and uncover its interiors. Thankfully the boxing is pretty neat and informative.

Thermaltake Smart 700W 80+

The front of the box displays a nice image of the Smart RGB 700W with its major specifications, it boasts a 120 mm Ultra quiet fan with RGB PSU fan with 256 colors as mentioned above. A promising warranty spanning over 5 years but unfortunately you can only enjoy a 2-year warranty in Pakistan.

On the sides of the box, they have elaborated the diverse pattern of RGB lights with a feature of different RGB options provided through a button.

Thermaltake Smart 700W 80+

The back side of the box is teeming with useful information regarding the Smart RGB 700W. We can observe its sublime features on the top left corner: Continuous 700 Watts output at 40C. It has High amperage with rail design. The efficiency description as 80 PLUS  230 V EU Internal certified. And the presence of 10 LED light bulbs for an aesthetic lighting experience. Further down we can see the Output specifications and an efficiency graph and on the right side they also provided connector specifications, there is a lot to gather from the boxing. Lastly, here we can observe the basic information regarding voltage support and efficiency specifications.

Now let’s get on with the unboxing, shall we? Inside the box, we have the main body neatly wrapped in bubble wrapping with the protruding bundle of cables, an instruction manual, booklet for warranty policy, four screws, and a power cord.

Closer Look:

Once we put the unwrapped body on the table, we can now closely observe the outer aspects of the body. In the first image, we can see the obvious model name clearly, “Smart RGB 700W”. Second image displays the socket for power plug and we have an on and off button just below that. They have covered this side with a shrouded mesh to carry out proper ventilation.Lastly the fun part, the button for toggling through different shades and modes of RGB lights. Top of the body is covered by the 12 mm RGB fan, quiet like the saint in a medidation.


Now, let’s take a closer look at the cluster of cables with the body. They have provided us with all the cables needed for a Smart RGB 700W PSU comprising of one 24 pin cable, one 4+4 pin for your motherboard, six SATA connectors, two PCI 6 plus 2 pin connectors, 5 Molex connectors, then we have one DD 4 pin cable. All of the cables have a nice mesh covering. This is a non-modular PSU with cables braided in a manner which is not easy to manage, the beginners will have a hard time with managing this mind-boggling network cables. But we can’t complain about that keeping view the fair price demand of this unit, you can learn some organizational skills to keep up with the management of these cables.

Next up is the RGB button on the side through which you can toggle around the lighting colors. This feature is a fine addition to the aesthetics as it can emit a wide range of colors which will pulsate while shifting to the next color. Or you can just fix it to one color with your RGB color button and have it pulsate, in a nutshell, it is a feast for your eyes, even better once you turn your lights off.  A power on/off button for the power supply. Moving on to the RGB fan which is a 120 nm Ultra-quiet fan. Keep that in mind, due to cost saving measures, that it is not a smart fan, which means it doesn’t turn off when the load is zero, nonetheless you won’t hear its sound at all.

The most highlighting feature of this PSU is it’s RGB Lighting, although it can be hideous because of the fan facing downwards in all of the modern cases, in some cases that expose the PSU fan, this PSU can be quite aesthetic for it. Also during my testing, I noticed that when the ambient lighting is low we can see the glow of the RGB Fan below the case, which looks really great IMO. However, the need of an RGB fan is kind of absurd in a PSU but still in this era of “RGB Everything”, Why not RGB your PSU as well?


Now, Let us dig a little deeper into this bad boy and open its casing. The interior view is pretty neat with tightly placed capacitors and other components. We can see a plastic glass covering the RGB fan.

Despite the tangle-prone bundle of cables protruding out of the Smart RGB power supply, they have neatly secured their exit through the body with cable bands inside as well as outside the hole. Furthermore, they ensured the safety of cables from damage resulting from constriction at the opening by inserting plastic plates lining the circumference of the opening.

Thermaltake Smart 700W 80+

They have meticulously put together the essentials of a running PSU i.e, the coils, heat sinks, capacitors, transistors, etc.

We can appreciate the well put heat sinks and the sandwiched transformers.

Heavy coiling is seen with the ventilating mesh.

The blatant craftsmanship is displayed when you look into all the neatly placed capacitors with the heavy wire coiling and an array of heat sinks to conduct the heat out of the PSU. The wiring may look a bit messy at first glance but it is in place with the build-up of the body.


We performed several stress tests under different conditions and load to the power supply with the careful measuring of voltages. The tool employed for this feat is a UNI-T UT203 Digital Clamp Multimeter Ampere Meter. Before I go on about the detailed performance analysis through meticulous readings, I shall shed some onto the noteworthy specifications and features this PSU encompasses.

First off, this PSU can render the limitations imposed by voltage distributions idle, as it is equipped with a single +12V rail keeping up with the constant provision of power to your system components according to their demands. Its efficiency is the next noteworthy perk it brings with itself, embodying 80 Plus rating efficiency, even though it is only on the standard 80 Plus version, it still has a satisfying competence promising the minimum power losses. Smart RGB is designed to work efficiently with Intel’s latest seventh generation Kayblake processor, achieving the maximum energy saving.

Last but definitely not the least, it provides a constant power of 700w all the time at 40 C which is one of the most important aspects you should never miss while buying a good PSU.

Complete in-depth review of a PSU easy no easy feat, it required the reviewer to be all set with the proprietary equipment in his arsenal, which is extremely costly, so, in our review, we will only be looking at the voltage stability of the PSU which can easily be done by a multimeter, as mentioned above. The multi-meter we used in our test was UNI-T UT203. We ran the Aida64 Extreme Stability test on all components to apply the experimental load to see how far can this PSU holed its own under these circumstances. Readings were then taken a few minutes into the stress test. These readings are for 3.3v, 5v, and 12v lines. Minimum and maximum readings were noted.

We also noted down the readings via Hwinfo to get a better idea grasp of the readings. However, we can’t ever be too sure of the reading from a software in lieu of Multimeter testing.

Our CPU was overclocked to a safe 3.8GHz to put maximum load that this system could without a GPU. We were applying 125Watts on CPU only with the Aida64 Extreme stress test, which is less than 20% power consumption than the total wattage the PSU can handle. So the values are expected to change in different settings.


Thermaltake Smart 700W 80+So according to our multimeter, we are off by 0.06v at best on the 3.3volt rail. That’s about 1.8% off. When it comes to 5v rail, we have a margin of 0.12 volts. That’s 2.37 in percentage. And our most stable line was the 12volt one. It mostly stayed at 12v however there was a dip of 0.02 volts here and there. So the readings here are very promising. Power Supplies have a tolerance rating and anything under 5% on the three rails mentioned above are acceptable. And it’s good to see that we haven’t even crossed half the limit here. So performance-wise, this seems like a good PSU.

Thermaltake Smart 700W 80+

And here’s our readings from the Hwinfo64 software. The 3.3v rail seems to be sitting idle on 3.3xx volts. There’s a difference of 1.74% in the 5v rail while the difference is even lower at the 12v rail. So once again, this seems like a solid performer. Staying away from the tolerance limits.


The Thermaltake Smart RGB 700W 80+ power supply is available for $67.99 on Amazon as of now. In Pakistan, it is available at a cheaper price at 6500 PKR on ShingPoint. Huge shoutout to Thermaltake for sending us the review sample.

In a nutshell, hopefully, the reader must have gotten a general grasp, if not tight, over our topic at hand, whether to buy Thermaltake Smart RGB 700w or not. Those enthusiastic gamers who are looking to turn it up a notch in their overall visual appeal of CPU along with a competent PSU upgrade under a stringent budget plan are, certainly, in luck. This is one of the best possible choice laid out in the market for them.  It is eco-friendly, cost-saving and competent enough to help your system elude any type of damage from overloading. And as all the pros mention about the Wattage of a PSU resting more on the consistent supply of wattage rather than the peak wattages which can be reached god knows when. This PSU provides a constant output of 700W at 40 C.

I am going to award the Thermaltake Smart RGB 700W Power supply with our Bang for the buck Badge because it did a great job in terms of performance and functions. The build quality also felt good, in comparison with the price tag of just $67 (USD) I must say its one of the best in this kind of budget.
