Thermaltake Toughpower DPS G RGB 850W PSU Review

In addition to its flagship Titanium line, Thermaltake also equipped the DPS G Gold family with an RGB fan. The highest-capacity model outputting up to 850W is our test subject today.

Protection Features, Evaluated

Check out our PSUs 101 article to learn more about PSU protection features.  

Our protection features evaluation methodology is described in detail here.

Protection Features
OCP12V: - 5V: 35.5A (142%) 3.3V: 32.5A (130%) 5VSB: 5.5A (183.3%), 83.12mV ripple
OPP1041.06W (122.4%)
OTPYes (secondary heat sink @ 97.5°C )
SCP12V: Yes 5V: Yes 3.3V: Yes 5VSB: Yes -12V: Yes
PWR_OKOperates properly
SIPSurge: MOV Inrush: NTC Thermistor & Bypass Relay

Over-current protection at 5V is set quite high. However, ripple is within the specified range in every case. This isn't true for the 5VSB rail though, which fails to keep its ripple below 50mV at 5.5A load, as the ATX spec requires.

The over-power protection is configured properly, while OTP is present and works just fine. Finally, there is SCP on all rails, including the -12V one. Again, the power-good signal doesn't last as long as the ATX spec requires, but at least it's accurate, dropping before the rails go out of spec. This means fake data isn't provided to your motherboard, effectively protecting your components from receiving a very low voltage input.
