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 | |
---|---|
OCP | 12V: - 5V: 35.5A (142%) 3.3V: 32.5A (130%) 5VSB: 5.5A (183.3%), 83.12mV ripple |
OPP | 1041.06W (122.4%) |
OTP | Yes (secondary heat sink @ 97.5°C ) |
SCP | 12V: Yes 5V: Yes 3.3V: Yes 5VSB: Yes -12V: Yes |
PWR_OK | Operates properly |
NLO | Yes |
SIP | Surge: 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.

powernod -It's not exactly a PSU-related question but more likely a general one.Reply
From the pictures from the monitoring software, i can notice that this software is able to measure CPU and GPU temperature. Do you have any idea if such monitoring is (relatively) accurate?
-Excellent review Aris !! -
Aris_Mp it takes readings from the system's (actually the individual components') sensors. If those are accurate then the software's readings will be accurate as well. Normally they are accurate.Reply -
Nuckles_56 That 12V transient response was certainly interesting, I don't think I've seen one do anything like that beforeReply -

Go and plummet back down to almost 0V during the test -

I don't think you're reading the transient response graph properly. It's not a measure of voltage but a measure of ripple (well, technically that is a measure of voltage but it's more a measure of instantaneous offsets of an average, or a highly zoomed in sector).
That or I am just missing something. I probably am. Not sure what I'm missing though. Forgive my ignorance. -
Nuckles_56 For this graph http://media.bestofmicro.com/ext/aHR0cDovL21lZGlhLmJlc3RvZm1pY3JvLmNvbS9TLzYvNjIxNzk4L29yaWdpbmFsLzEydl9vZmYuanBn/r_600x450.jpg I hope that I'm not reading it that badly wrongReply -
sparkyman215 Fantastic review Aris! I absolutely love reading in depth articles about anything. Terrible PSU for the price, but it's an awesome review. Congrats!Reply
