Thermaltake Toughpower GF1 1000W Power Supply Review

How Much Does it Cost?

Currently available for a price in the region of £139.99, I think it would be fair to say that the Thermaltake Toughpower GF1 1000W isn’t an inexpensive power supply. You do, however, have to consider exactly what you’re getting here. – Not only is this a 1000 watt power supply rated to an efficiency level of 80-Plus Gold, but this also comes with a comparatively huge 10-year warranty.

This power supply shouldn’t just be considered for use as a one-off purchase. There is absolutely no reason why this shouldn’t outlive the vast majority of your components making it not only suitable but entirely ready for future builds and upgrades as you progress as a PC owner (and particularly so as components such as processors and graphics cards get even more power-hungry!).


As seen throughout our testing, the Thermaltake Toughpower GF1 1000W is undoubtedly an absolutely fantastic power supply. Both inside and out, there is practically nothing to fault here and particularly so in its efficiency which performed much higher than its official 80-Plus Gold rating would suggest. In many respects, this is actually closer to Platinum which, while not quite making that level, if it did, you could easily expect to see another £30-£40 thrown onto the price tag!

Admittedly, not everyone is going to need a power supply with 1000 watts of output. Given that this GF1 range is available from 650w all the way up to 1200w, however, based on the components you have in your system, there is something for everyone here that will not only do the job but do it exceptionally well!

Practicality & Functionality

Offering high levels of efficiency (that could save you a not unnotable amount on your electricity bill), a fully modular cable design, an easy to work with cable interface, and plenty of functionality for system management and overall airflow, the Thermaltake Toughpower GF1 1000W is about as practical as things (currently) get. – This isn’t, of course, going to be suitable for a lot of MITX system cases, but I daresay that if you’ve gotten to this point of the review you probably know this already.

A key factor to consider though is that while 1000 watts of power might seem like a lot, it’s hard to deny that as system components get faster, they are often now requiring substantially more power to do so. For a top-spec gaming system, 1000 watts is about where you need to be now and particularly so if you’re considering a PSU purchase as a long-term investment. As such, the Thermaltake Toughpower GF1 1000W does appear to present even more practicality when that factor is brought into the mix.

Should I Buy One?

Although other power wattage outputs are available in the range, the Thermaltake Toughpower GF1 1000W does seem to tick all the right boxes for high-end gaming PCs and enthusiast-level users. A particular factor of note is the power output which clearly offers more than a little for the overclocking community. – No, this isn’t a cheap power supply, but that’s because this isn’t a cheap power supply!

The quality both inside and out of the Thermaltake Toughpower GF1 1000W is unquestionable, and although this already comes with a huge 10-year warranty, we’ve seen nothing to suggest that this couldn’t still happily keep your system running for 20 years and perhaps even longer. – Put simply, the Thermaltake Toughpower GF1 1000W is a quality product, and for those who know their power supplies, this is undoubtedly one of the best options currently available on the market!
