A fake power-good signal in a high-end PSU? This is unacceptable! We simply cannot understand why CWT didn't tune its power-good signal properly.
Inrush Current
For details on our inrush current testing, please click here.
The inrush current we measured is pretty low, given this PSU's capacity.
Load Regulation And Efficiency Measurements
The first set of tests reveals the stability of the voltage rails and the TPI-1200F2FDP's efficiency. The applied load equals (approximately) 10 to 110 percent of the PSU's maximum load in increments of 10 percentage points.

We conducted two additional tests. During the first, we stressed the two minor rails (5V and 3.3V) with a high load, while the load at +12V was only 0.1A. This test reveals whether a PSU is compatible with Intel's C6/C7 sleep states or not. In the second test, we determined the maximum load the +12V rail could handle with minimal load on the minor rails.

Load regulation is very good on all of the rails, although Thermaltake cannot beat the amazing performance levels of Seasonic's Prime Platinum, which is based on a pure analog design. As mentioned, digital platforms might be the future. However, more work must be done before they're able to consistently beat their analog adversaries.
As far as efficiency goes, the TPI-1200F2FDP clears the 80 PLUS Platinum requirement with 20% load, comes close to its target with 50% load, and falls well short of 89% under full load. Obviously, the high temperature we use for testing plays a huge role in the efficiency levels our equipment measures (compare that to 80 PLUS' results, recorded at an unrealistic 23°C, +/-5°C).
Thermaltake's fan profile is fairly conservative. It's only when we push the TPI-1200F2FDP hard that its fan spins up and gets noisy. Up to 70% of its maximum-rated capacity and with an ambient temperature of 43°C, the PSU generates ~26 dB(A) of noise. That's amazing for a 1.2kW PSU. CWT has proven many times that it's able to build high-wattage platforms that don't get loud. The TPI-1200F2FDP is another example of this.

pjmelect Your videos don't work I get the error "cannot load m3u8 crossdomain access denied (2048)"Reply -
Co BIY Everyone reviews heavily on capacitor quality but how is cap quality determined ? Is it published specs or just reputation / country of origin ?Reply
The bad cap crisis was over ten years ago are all those makers
still putting out bad or inconsistent products ? -
Aris_Mp The videos work fine for me.Reply
Caps: Mostly based on experience and the RMA data that I have access to. The quality of the electrolyte is what matters the most. -
Mike Adams CapXon & Su'scon caps? more chinese junk for a premium price. I would never buy anything from ThermalsewerReply
