Well if you haven’t ever seen an SFX power supply, they are considerably smaller than your standard ATX power supply. It’s hard to tell with a normal picture, but the SFX PSU is about 5 inches wide and 4 inches long. A normal power supply is about 6 inches square. There are two SFX form factors SFX that Thermaltake went with and the SFX-L platform that is square.
The side profile of the Toughpower 450W that you will normally see through a side panel window is simple, just like the packaging for the power supply. Up top is a grey strip with the Thermaltake logo and the Toughpower branding. Then down on the bottom is a small 80 Plus Gold logo and then the Toughpower SFX 450W branding with the wattage highlighted in large white letters.
Like Silverstone and Corsair, Thermaltake went full modular with the Toughpower SFX 450W. Each of the connections has a label printed on the side of the power supply and to make sure you can tell the difference between the 8-pin CPU connection and the PCI-e connection the PCI-e plug is bright red. Each of the connections does stick out slightly from the power supply and the panel is knocked for each of the retention clips as well.
Up on top of the Toughpower SFX 450W is a large sticker. Here they have a full output specifications breakdown. There is a whole section filled with all of the different certifications and standards including the 80 Plus Gold certification. They also slipped in a logo for the 7-year warranty as well.
On the back of the Toughpower SFX 450W, the entire back is covered in hex grid venting. The power plug is up in the top left corner but it comes covered by a warning sticker reminding you that the fan turns off under low load. We have been seeing this on video cards as well, I guess a lot of people have been freaking out and calling support when they look in and don’t see their fans turning on when they turn their PC on.
Speaking of fans, the bottom of the Toughpower SFX 450W has an 80mm intake fan. It’s a little weird seeing a fan not taking up the entire bottom of a power supply these days, but the SFX form factor is a rectangle and there isn’t room for a large 120mm fan. Corsair, however, was able to pack a 92mm fan into their SFX power supplies. The 80 does match what Silverstone has on their SFX power supplies, though.
For cables, you really only get a few thing, one for each of the modular connections on the power supply. You get a 24-pin motherboard power cable and an 8-pin CPU power. The cable with red ends on it is the PCIe power cable, it has two 6+2 connections on it. This covers any variation of video card you will run into but will of course only handle one card. Being an SFX power supply I doubt many people will be trying to pack two cards into them. Then for accessories, you have one Molex cable with two connections as well as a floppy connection, who knows why we need that floppy connection anymore, though. Then the last cable is a SATA power cable with three connections on them. Each of the cables is shorter than they would be with a normal power supply, especially the 24-pin motherboard power that is 13 inches long. Being for SFF cases, there is no room to hide a bunch of extra cable so that that is a good thing.
All of the cables including the 24-pin all come in all black flat cabling. I wouldn’t use a power supply these days that didn’t have flat cabling, its always clean looking and you can fit the thin cables into tight spots. They are also very flexible so if you do have any extra cable length you can fold them up and hide them really well.
