Thermaltake Toughpower SFX 600W PSU Review

The highest-end member of Thermaltake's Toughpower SFX Gold line is on our test bench today. It offers Gold efficiency, modular cabling, and a semi-passive fan mode. Thanks to its 600 W capacity, you can easily build a powerful system with it.

Cross-Load Tests And Infrared Images

Our cross-load tests are described in detail here.

To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 25,000 possible load combinations with the +12V, 5V and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12 V, 5 V and 3.3 V) as point zero.

Efficiency Chart

Although this isn't one of the most efficient SFX platforms we've tested, for a large swath of its operational range, efficiency does register between 90 to 92 percent.

Infrared Images

Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

The single PCIe cable with its two corresponding connectors is the hottest of all cables, since it delivers a significant part of the PSU's max power. With two of those cables and four PCIe connectors in total, the load would be divided in two, so the cables wouldn't get as hot and the PSU's functionality would increase.

Inside the STP-0600F-G, temperatures appear normal. Apparently, the small fan does a good job, and the large heat sinks help as well.

    Hard to compete with the SF Corsairs.

    Based on this review, I wouldn't buy the thing for half its listed price. How the devil did it get a Gold rating, anyway?

    You would only need 2 pcie cables since these psu are designed for sff builds, with only 1 gpu since you also use a m-itx board.

    This power supply is a disaster. It does not have working protection circuitry and should be a 450W unit, not a 600W unit.

    This thing sucks.

    This unit is a 450W power supply IMO. Basically, Thermaltake probably took their 450W power supply, slapped 600W on it, kept the same amount of PCIe cables, and called it a 600W power supply. This power supply is stupid, I don't know who would buy it. That's just my opinion of course, but safety should be the most important thing of a power supply, and even thought it didn't blow up, if it had 510mv of ripple at 110% load, imagine what it had at 140% load before it shut off? Probably 2000mv of ripple. There goes the GPU. There goes the CPU. There goes everything!

    But Thermaltake knows that not a single person who purchases this thing will have done their PSU research, and therefore not a single person buying this thing will probably have a system that demands more than 250-300W. Thermaltake preys on the vulnerabilities of the uneducated, it's a disgrace, it's disgusting.

    You wouldn't need a 600W power supply with an SFF build period. It razzes my berries that the mere fruit of the existence of this thing is an example of an unethically engineered product that nobody needs but is designed for those who don't know what they don't need.

    Not until the Corsair SF Series was released while I was sitting behind a desk at Corsair did I realize just how many people use SFX power supplies in full size cases. Absolutely AMAZES me. So.. yeah...

    Dont know if a 300mm 24-pin cable could reach the board in a full sized case.

    As much as I give Tomshardware a lot of pain for many of their articles This one is a very solid test.
    The PSU is one of the most important parts of the PC (Id say its THE most important), so a good review of a PSU is always welcome.

    Well done toms.

    I commend Thermaltake for releasing into the SFX market , more competition is good for the industry. With very little to choose from , it's still a huge plus to have more SFX units out there on the retail market.

    Yeah but this is not what I'd call competition... Nobody needs to compete against Thermaltake's product since it stinks.

    GOOD QUALITY as usual on Enhance but seems they need smart enginiers to up level to the designs. wireless etc
