A Closer Look

The Thermaltake Toughpower branding generally tends to take a no-nonsense approach with a sleek and professional style. Although ARGB variants of this power supply are available, there is something nice and reassuring about a no-thrills and all-business style.

Where there is branding to the power supply, it is both subtle and well thought out. This doesn’t scream to get your attention, but it does (as politely as possible) remind you that this is a Thermaltake Toughpower product.

The power input bank is, in so far as these can be interesting, a little unusual. The ports available exactly match those provided with the cabling which (as we noted earlier) is somewhat different to the ‘norm’ in that there are only 3 PCI-E/CPU ports. Usually, most power supplies (even 550-650w) designs will have at least 4 of these. Even if they’re only provided with 2 cables that can fit in them.

Admittedly, additional ports are not much use without the cables, but this actually impresses us a little in a roundabout way. This panel has been specifically designed for this particular power supply. No waste, no junk, just ports for everything you have and could possibly need.

They’re also well spaced out and with the ‘back to back’ design, make removal and insertion easy.

Finally, getting to the main exhaust vent, this is a little bit more standard of what we’d expect to see. You’ll note the zero-fan switch and, in addition, the nice and large vented area which hasn’t wasted any space.

This should, at least in theory, really help temperatures and keep the fan running as minimally as possible.

The cabling to the Thermaltake Toughpower GF1 has a nice sleek and thin black design which was very easy to work with. If there is a criticism to be made of it, however, it’s the length.

Although I did not specifically measure each one, the cables were generally 50-60cm in length. This shouldn’t prove to be a problem for the vast majority of consumers, but it is something to note if your chassis is notably large or you plan to do an intricate bit of cable weaving/management. You might find yourself a little tight in places.

Internals – A Look Inside!

A cursory look at the insides of the Thermaltake Toughpower GF1 immediately impresses you with how neat and tidy it is. You’ll see no sprawling cables nor huge blobs of glue. This gives you a lot of confidence as to the build quality here.

The fan provided with the power supply is a Thermaltake own TT-1425. We have seen this fan used many times in the past and have never failed to be impressed with its performance and particularly it’s quiet operation.

If there is an interesting factor to note of it, this is the exact same fan used in the ARGB variant. We can, therefore, presume that this fan is, in theory, RGB capable. Although clearly the PCB nor the body of the PSU case has been designed to allow its operation. It’s neither a criticism nor a compliment, I just find it interesting that they do use the same fan for both variants.

A closer look at the PCB and components show just how excellently this power supply has been assembled. A particular highlight is the large areas of open space between all of the key parts and particularly the heat sinks which are located just off centre to get the most benefit from the fan’s operation.

With one of the key features of this power supply being Japanese capacitors, although we trust Thermaltake implicitly, we do have to check this to be sure. Fortunately, there’s nothing to worry about here. With both main capacitors coming from ‘Nippon Chemi-Com’ this is indeed a Japanese manufacturer and an excellent one too!

Overall Thoughts!

So, in terms of presentation and design, the Thermaltake Toughpower GF1 looks truly excellent. How does it actually perform while doing its job though? – Let’s find out! Onto the tests, but first, a little methodology!
