Thermaltake Toughpower DPS G RGB 1250W PSU Review

Thermaltake recently released a new flagship Titanium-class PSU, the Toughpower DPS G RGB with 1250W max. power. Besides an RGB LED fan, this unit also features high performance, modular cabling, and compatibility with the SPM cloud platform.

Our protection features evaluation methodology is described in detail here.

Protection Features
OCP12V: - 5V: 34.08A (170.4%) 3.3V: 34.75A (173.75%) 5VSB: 5.4A (180%), 59.05mV Ripple
OPP1444.72W (115.6%)
OTPYes (+12V FETs @ 105°C)
SCP12V: Yes 5V: Yes 3.3V: Yes 5VSB: Yes -12V: Yes
PWR_OKOperates properly
NLOYes
SIPSurge: MOV Inrush: NTC & Bypass Relay

OCP on the minor rails is set too high, especially 5VSB. With 5.4A current output, it registers over 50mV ripple. On the other hand, the OPP triggering point is normal. Also, we had to raise the temperature to 105 °C on the bus-bars that cool the +12V FETs to trigger OTP, which shut the PSU down.

There is short-circuit protection on all rails, and the power-good signal drops before the rails go out of spec, per the ATX requirements. Finally, the PSU operates normally with no load on its outputs and is equipped with the necessary components that protect against power surges and large inrush currents.
