Thermaltake has introduced its first SFX power supplies designed for gaming PCs. The new Toughpower SFX series of PSUs will have two models, both of which are 80 Plus Gold rated and feature a modular design. Thermaltake, which is primarily known for its PC cases and high-power PSUs for high-end PCs, will become the fourth major PSU maker to introduce gaming-grade SFX power supplies after Corsair, FSP and SilverStone.

The Thermaltake Toughpower SFX lineup will have two SKUs rated for 450 W (STP-0450F-G) and 600 W (STP-0600F-G, STP-600AH1FEG) maximum load. Both power suppliers are compliant with SFX12V V3.3 and ATX12V V2.4 specifications as well as carry the 80 Plus Gold certification. Thermaltake advertises three key features: the 80 mm fan that does not operate at low loads, a modular design with flat-type cables to ensure easy cable management, and a seven-year warranty. Thermaltake also includes an SFX to ATX adapter bracket into the package to make its SFX PSUs compatible with Mini-ATX builds as well, which is logical since the power supplies were developed with general gaming PCs in mind and can be used for a variety of PC cases, not just for tiny ones.

The Toughpower SFX PSUs will have a similar internal design (but not exactly the same, see images below) as well as an identical set of connectors. Both power supplies feature EPS12V power connectors (one 24-pin and a 4+4-pin connector), a single PCIe 6+2-pin power connector, one SATA power connector as well as one connector for peripherals.

Connector type Hardwired Modular
ATX 24 Pin - 1
EPS 4+4 Pin - 1
PCI-E 6+2 Pin - 1
SATA - 1
Peripherals - 1

Since both PSUs have only one PCIe 6+2-pin power connector, they are compatible with modern graphic cards that use only one 8-pin PCIe auxiliary power input. Some users may feel that 600W with only one PCIe connector is very limited, and will cut out some of the most powerful small form factor GPUs.

Thermaltake’s Toughpower SFX PSUs should hit the market shortly, but we do not have the prices at this time.

    Please please please please don't be $90+ for a basic 500w 80+ gold, like the other price gouging SFX power supply manufacturers. Reply

    I thought that couldn't possibly be correct, but you're right. The cheapest "premium" SFX PSU that anyone would actually want to put in a build (modular, 80+ Gold, etc) is $87.99.

    i dunno, $90 is dirt cheap imo especially for fully modular Reply

    I wouldn't buy a Thermaltake Power Supply unless it was dirt cheap. Reply

    Not really.

    As of the time of this post, a fully modular 80+ Gold "Rosewill PHOTON-550" retails for $59.99, while a "Corsair RM550x" retails for $69.99.

    Relatively speaking, SFX is costing ~1.33x as much for the same crap. And honestly, I wouldn't care if it was modular, so long as the cables were short enough for a SFX case build.

    That corsair you listed retails for $119.99, show me where you can buy it for $70. and the Rosewell is $69.99 with a $10 rebate lol...

    F rebates on power supplies. i hate them

    Unfortunately the Corsair jumped in price since I last posted about it.

    Still, my point stands that SFX power supplies are much more expensive than ATX power supplies, of the same class and features, and there's very little reason for it.

    Miniaturization isn't free. Or to put it the other way around, full ATX PSUs can use bigger and cheaper components because they have more space to play with. Economies of scale also come into play on the side of full ATX units. Reply

    On the other hand, I am paying more money for less mass in materials, many of which are precious materials used in capacitor, transistor, and other circuitry, a smaller whinier fan, etc. I hardly doubt the slightly smaller components have a huge factor between ~500w ATX and SFX PSUs. SFX PSUs just get an absurd markup which adds to the already uncomfortable cost of going with a small form factor build.

    Seeing as Thermaltake was manufacturing it, and Thermaltake does provide lower price competition, my hope is that they help push prices down on these PSUs to more reasonable levels.

    "Since both PSUs have only one PCIe 6+2-pin power connector, they are compatible with modern graphic cards that use only one 8-pin PCIe auxiliary power input. "

    According to TT's web site both models include a cable with *two* 6+2 connectors on it, so you could run two 225W or one 300W GPUs to fully utilize the output from the 600W model.

    The 450 includes the same cable; although using it to try powering a pair of GPUs that each need an 8 pin connector runs the risk of overloading the PSU and causing it to shut down.
