Thermaltake Toughpower GF1 1000W TT Premium Edition PSU Review

A Closer Look

Thermaltake’s packaging is pretty consistent and covers everything you need to know. Features and specifications are listed as expected, but Thermaltake goes the extra mile and shows the number of each connector, as well as efficiency and fan curve information.

Inside, the PSU is well protected in a block of foam with everything else in a bag next to it.

Inside, you get the usual paperwork and a nice bag that contains all of your cables. It’s handy as it gives you a nice place to keep all of your unused modular cables for the next built. With a 10 year warranty, it’s a safe bet you’ll be using the GF1 through a few builds.

Thermaltake keeps with the same slotted grill pattern it has used on most of its Toughpower PSU’s the last handful of years. A Large TT badge sits centered over the fan hub.

The underside has a large label that lists all of the electrical specs.

The sides of the Toughpower GF1 have the same label with the top quarter or so of the side vented for maximum cooling.

The rear keeps the same slotted design that covers the entire rear panel. You have the usual C14 power inlet, a mains power switch, and a smaller switch that enables or disables the Smart Zero Fan mode. With this switch off, the cooling fan always runs, with Smart Zero Fan on, the fan will stop entirely at low loads where there is little need for cooling. Personally, I really like when this is a user-configurable option as I prefer a small amount of cooling since the fan is pretty much inaudible anyway. If you live in an anechoic chamber, maybe you prefer the dead silence.

The business end of the ToughPower GF1 is entirely modular with five sockets for CPU or PCIe power, and four connections for peripheral cables.

Cables include the main 24 pin, two eight-pin EPS (one of which is configured 4+4), three PCIe power cables, each with two 6+2 pins in a daisy chain, three SATA only chains, and a single legacy Molex 4-pin chain. You also get a berg adapter, some zip ties, and mounting screws. The ToughPower GF1 also comes with a regionally appropriate mains power cable as well.
