While no one at home should be opening their PSU, Thermaltake have placed a red accented strip completely around the chassis which has to be destroyed to open it. This should not affect customers, but we were saddened to have to ruin the looks of the PSU to get inside it.
The TT 1425 Fan is a Brushless DC 12V model designed by Yen Sun Technology (or YSTech as most people will know them by). I have fond memories of using YSTech fans on my CPU coolers many years ago and it is great to see Thermaltake adopting their products. The fan is rated at 120,000 hours minimum life and spins at a maximum of 1,900 rpm.
Internally we can see high quality Japanese made electrolytic capacitors and solid state capacitors to handle the DC-DC converter module and 3.3V and 5V ripple. Solid state capacitors offer longer life time with increased stability and reliability.
Above close ups of the DC-DC Converter module inside the ToughPower Grand. This delivers synchronous rectification of +12V & DC to DC conversion of +3.3V and + 5V circuitry. This helps to maintain tight DC output to reduce compatibility issues while enhancing the stability of the voltage output. Additionally this gives high levels of dynamic response and increases efficiency levels.
The new Active PFC circuit in the GRAND is a double forward switching circuitry design which gives lower power loss and higher reliability and is able to reach high efficiency rates at various load levels, right up to full load. We will obviously test this out later.
The ToughPower Grand 750W unit can deliver up to 60A on the 12V rail, it was a deliberate design decision from Thermaltake to create a single, powerful 12V rail to ensure maximum compatibility and performance. The 650W model can deliver 52A on the 12V rail. The PFC coil is on the left on the image above with the main transformer in the middle.
The Toughpower Grand series are also able to maintain an ultra tight DC regulation to support C6 state CPU mode by the Zero Load (0W) design.
Above left we can see the EMI Filter and X and Y Capacitors with surge protection. Above right is a close up of the heatsinks which populate and seperate various sections of the design.
The cabling is braided completely into the chassis to ensure protection against the fraying of any wires. Everything is well shielded inside to keep crossover and potential issues negated.
While I don’t think its important to have a ‘pretty’ PSU, this is quite stunning visually. technical data certainly shows its going to do well.
Looks like its going to be just under 200 bucks in the US. very good pricing.
Very nice product, i like it, great appearance.
This is great thank you, I have been waiting on a review of this for a few weeks. very nicely done. the strip idea is weird, but I suppose it wouldnt be an issue for people at home as they shouldnt be opening the PSU anyway.
That is a very nice looking power supply. i love the shaped edges. Technically it seems the muts nutts too.
Wanted to mention I like the thermal testing idea of 35c. I know some sites build hot boxes to 50c which is a good idea too, but it never seems very realistic to me.
Very well designed and I liked the video. no offense to the bloke but it looked like something out of a war film. ‘this is a bomb, and it will blow up if I push ze button”.
I like the internal structure, its a modern design which is proved to work well, especially with variable load changes.
Any ideas when this might be released?
Very good product, but to be fair their last range of toughpowers were pretty good too.
Thats an excellent review, this seems like a killer PSU, but one question. Why did they make the red stripe like that? surely that would have been better built into the chassis itself.
Very good product
