Thermaltake Toughpower GF2 ARGB 650W Review

Thermaltake Toughpower GF2

Another Thermaltake product has found its way into the lab for review today. This time we’ll be taking a look at the Thermaltake Toughpower GF2 ARGB 650W PSU.

This fully-modular PSU sits at a premium position and comes with the price tag to prove it. Just what all do you get for your money, and is it worth a purchase? Read on to find out.


The front of the Toughpower GF2 PSU box isn’t shy about listing specs and features. At the top left, RGB support is noted via the Ring Duo fan that keeps the components cool. The PSU also sports support for a fan that shuts off completely during low-power scenarios, saving marginal watts and noise. The box promises low ripple noise, an important inclusion for overclockers, and quality Japanese capacitors. Most importantly, the product sports a 10-year warranty, commensurate with the price and positioning. Finally, modular cables are a must, and Thermaltake hasn’t left that off in this premium power supply.

On the back of the box, Thermaltake goes into additional details regarding a few of the claims made on the front. The charts show what Thermaltake means by low ripple, comparing it to the acceptable standards published by Intel for PSUs and what this PSU is capable of. No surprise, the PSU is claimed to exceed the standards. A chart showing efficiency is also included. As you can see, efficiency peaks around 50% load, and you should generally aim to have your system running at that load to save the most on your power bill. This means if you’re typically gaming on your system and drawing large amounts of power, you may want to go for a larger PSU. Conversely, if your system is middle of the road drawing 300-400 watts while under use, you’ll see peak efficiency with this 650W PSU. Several logos of RGB sync are also included to show compatibility.

Contents of the box are simple, with the Thermaltake Toughpower GF2 being protected by foam and the cables contained in a nice branded velcro bag. The bag is a nice inclusion as you are unlikely to use the plethora of cables included on this, but you don’t want to get rid of them as you’ll likely need them down the road.

Inside the black branded bag, a collection of cables nicely bound individually are stashed. Thermaltake has also included screws for mounting and some zip ties to help with cable management.

On the front of the PSU, all of the various connectors for the previously seen cables are laid out and labeled clearly. There is also a port to connect the PSU to the motherboard to sync the RGB LEDs included in the PSU and its fan.

The back of the PSU has RGB controls, which allow selection of RGB mode and the color. You can also elect to disable the smart zero fan function. Of course, there is a power switch and a place to plug in the main power cord behind the smart zero fan information. 

We loaded it into our Divider 300 case and powered up some serious hardware to test this PSU to the max. We maxed out the power draw of a 6900XT using Furmark and maxed out the power draw of the Intel Core i9-9900 with prime95. AMD recommends an 850W PSU for the 6900XT, but it’s been running just great on this premier 650W PSU. Of course, since I am loading the PSU closer to 100%, the efficiency will not be as good as a larger PSU.

With both the CPU and GPU power draw maxed, I recorded a power draw of 535W at the wall. Software reported the GPU as using 255W and the CPU as using 150W of power. This PSU has no issues powering the latest and greatest power-hungry gaming hardware–nor should it. The fan, of course, cannot be heard over the rest of the system’s fans, which is great.

Pictured above installed inside the Divider 300, the Thermaltake Toughpower GF2 ARGB features excellent self-branding, with the logo and hardware name being nicely highlighted by the RGB. We appreciate the inclusion of the ability to shut off the RGB to the PSU separately when a stealthy appearance is desired.


Bottom line, Thermaltake is asking for a premium price for a premium product. At $179.99 MSRP, it is a bit steep for what ultimately amounts to a 650W PSU, but the included features and specs–and the 10-year warranty!–would give me comfort at night running a slightly undersized PSU than I would normally run. Is it worth the price differential from other PSUs in this wattage rating? Ultimately, only you and your budget can make that decision.
