Protection Features, Evaluated

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

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
NLOYes
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.

    -It's not exactly a PSU-related question but more likely a general one.
    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 !!

    in corsair link software atleast both cpu and gpu temperatures are accurate.

    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.

    That 12V transient response was certainly interesting, I don't think I've seen one do anything like that before

    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.

    For this graph http://media.bestofmicro.com/ext/aHR0cDovL21lZGlhLmJlc3RvZm1pY3JvLmNvbS9TLzYvNjIxNzk4L29yaWdpbmFsLzEydl9vZmYuanBn/r_600x450.jpg I hope that I'm not reading it that badly wrong

    yes this is something really weird indeed.

    Fantastic review Aris! I absolutely love reading in depth articles about anything. Terrible PSU for the price, but it's an awesome review. Congrats!
