Thermaltake Toughpower SFX 1000 Watt Fully Modular 80+ Platinum Power Supply Review

A Closer Look

The latest Toughpower is an SFX power supply, so it’s a very small form factor, which I think is incredible, as getting a 1000W in this form factor is pretty exceptional. I’ve been doing PSU reviews long enough to remember when 500W 80 Plus Gold was impressive in an SFX PSU, and 1000W Platinum PSUs would have been massive. This means you can now power the latest graphics cards such as the RTX 4090 and any flagship processor from this tiny power supply, meaning you can have smaller and slimmer PC cases.

It looks stunning, with that huge perforation on the fan grill and a 90mm hybrid fan on the inside to keep things cool, but it can operate at 0 RPM under 30% load so it’s completely silent when you’re just doing your day to day work or watching YouTube.

Down the side, there’s a simple branding sticker.

There’s a good amount of ventilation at the rear of the power supply, and an AC line-in and power switch, so all pretty straight forward stuff really.

There’s a sticker on the base, showing all the main specifications, and as you can see, it can deliver 83.3A/1000W on the +12v rail.

Then onto the business end, you’ll find a fully-modular design, with the ATX 24-pin split into two headers, four CPU/PCIe 6+2 connectors, three peripheral connectors, and then a full 600W capable 12VHPWR (12V-2X6).
