The Toughpower series of power supplies from Thermaltake is one of the most renowned series of power supplies around and for good reason. The units refuse to compromise on quality anywhere and can handle abuse, day after day after day. The Toughpower Grand units take things a little further and add in beauty to the lineup for those that are seeking both performance and aesthetics.

Today we have the new Toughpower Grand Platinum 700W power supply on the test bench. Thermaltake has upped the efficiency of the unit to provide 80 PLUS Platinum efficiency and delivered and all white unit, including cabling. It will take a lot more than some good looks and high efficiency to make this unit live up to the Toughpower Grand name, so let's see what it is made of as far as specifications go.

Specifications, Availability and Pricing

Thermaltake Toughpower Grand Platinum 700-Watt 80 PLUS Platinum Power Supply Review 02 | TweakTown.com

The Toughpower Grand Platinum 700W utilizes a single 12V rail to deliver most of the power and it is rated for 58A or 99% of the total output of the power supply. Both the 3.3V and 5V rails are rated for 22A with a combined output of 120W. The 5VSB rail is rated for the average 3A or 15W. Maximum combined output for the TPG-700M is 700W.

Just as you'd expect from something bearing the Toughpower Grand name, the TPG-700M's feature list is filled full of checkmarks. All protections are present including SCP, OVP, OCP, OPP and OTP. The power supply features both native and modular cabling. All cables are white and fully sleeved or of the flat ribbon variety. It is rated for 80 PLUS Platinum efficiency and 100% continuous output at 50C.

Thermaltake has an MSRP of $179.99 for the Toughpower Grand Platinum 700W power supply. You'll find it with a $10 premium on Newegg, but you'll also have to cough up some shipping to bring the total up to $201.29. This easily makes it the most expensive Platinum rated power supply in the 700W range available. Thermaltake backs the Toughpower Grand Platinum 700W with a seven year warranty.

As far as accessories go, there is quite a bit going on there. There are two rubber vibration isolation mounts designed for the corners of the power supply. To accommodate these, four long mounting screws are also included. Cable management is provided in the form of some zip ties as well as two plastic cable locks.

Cabling Arrangement and A Look Inside

Cabling Arrangement

The cable selection and connector availability for the Thermaltake Toughpower Grand Platinum 700W is about as perfect as you can get. There are dual EPS12V connectors for systems that need it as well as four PCI-E connectors over three cables to provide enough power for two high-end video cards. There are also eight SATA and six Molex connectors available for peripheral devices. The only thing that would be nice to see is the second EPS12V connector made modular as few will need it in a mid-range power supply and it will just provide clutter on the inside of a case.

Rail distribution is as simple as it gets with a single 12V rail. There is no need to worry about load balancing here.

A Look Inside

Inside we have a very open unit with two large heat sinks running the length of the power supply. The PCB is also somewhat compact and Thermaltake could have used a shorter enclosure if they had wanted.

A single Panasonic capacitor sits on the primary side of the Toughpower Grand Platinum 700W power supply.

The secondary side is packed full of Nippon Chemi-Con caps.

Thermaltake uses their own TT-1425 140mm fan to provide the active cooling for the TPG-700M. This fan is simply a rebrand from Yen Sun Technology.

Test Results and Final Thoughts

Test Results

Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.

The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits are higher than to that of the Thermaltake Toughpower Grand Platinum 700W power supply, we can test it to the maximum.

The above tests represent typical loads that we have measured from various systems and are meant to give a rough idea of where your computer might fall in line with our tests. Please keep in mind that each system is different and actual loads can vary greatly even with similar hardware.

Let's start by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V rail, we see 1% regulation from start to finish with a total drop of .10V. The 5V rail managed to stay within 2% of specification with a total drop of .05V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 1% of specification with a total voltage drop of .04V.

DC Output quality for the Toughpower Grand Platinum 700W was okay, but well within specification. During Test 1, we saw 22mV of noise on our scope. When we increased the loads in Test 1, the ripple climbed to 33mV at a little under half load. During Test 4 under a load of 700W, the oscilloscope showed a maximum of 52mv on noise on the 12V rail.

The Thermaltake Toughpower Grand Platinum 700W is rated for 80 PLUS Platinum efficiency. This means that the power supply must perform at 90%/92%/89% efficiency at 20%/50%/100% loads respectively. As you can see, the Toughpower Grand Platinum 700W passed on our bench, and wasn't close to failing at any point.

Final Thoughts

As we stated from the start, the Toughpower Grand series is known not only for its performance, but also the aesthetic design. As far as aesthetics go, the TPG-700M does an amazing job. It looks fantastic in white with some high-contrast black to accentuate it and provides yet another option for those seeking something other than a black power supply. It should match very well with white cases such as Thermaltake's own Level 10 white cases.

The performance of the Toughpower Grand Platinum 700W is almost just what we expected, too. Voltage regulation is superb, coming in at 1% on the 12V and 3.3V rails and 2% on the 5V rail. Efficiency is superb as well, giving us just what is advertised. Where we are a little surprised is in the DC output quality department. We expected a bit better noise suppression, especially considering the reputation of the unit and the build quality we saw. Regardless, 52mV of noise on the 12V rail is far from being bad, but there are many units on the market that do it better... including other Thermaltake units.

The sad thing is that all of this comes with a somewhat high price premium that is made worse by a bit of gouging done by Newegg. At least Thermaltake sweetens it up a bit with a solid seven year warranty, ensuring that your investment is going to be around for a while, even if there happens to be an issue with the unit down the track.
