You're unsure about the safety features of PSU, such as SIP?
Hello, little question about PSU safety features. Choosing new PSU with bigger capacity I got a bit confused.
My choices around pretty popular mid-range+ 850W\1000 variants, few examples:
Seasonic FOCUS GX FOCUS GX-850 850W
MSI MPG PCIE5 A850G PCIE5 850W
MSI MAG PCIE5 A850GL 850W
be quiet! Pure Power 12 M 850W
All of them have protection futures like :
OVP – Over Voltage Protection
OPP – Over Power Protection
OCP – Over Current Protection
SCP – Short Circuit Protection
OTP – Over Temperature Protection
UVP – Under Voltage Protection
But when I looked for my current old budget PSU Chieftec 600W Proton, and their newer variants Chieftec 1000W Proton & Chieftec Polaris PPS-850FC(80+ Gold) , they have all of the above protection features plus
SIP – Surge and Inrush Protection
.
Why this more budget friendly PSU have all of this protection features but not Seasonic or be quiet! ?* Or this is just by default ?*
😵
Or i`m missing something and SIP not a big deal?
It could be connected to the watt rating. This function is linked to the big power surge that happens when you first turn on the power source and it charges the capacitors. It helps avoid accidentally tripping the power breaker at home. Most breakers are designed to handle a minor spike, such as from a refrigerator motor or wall AC units, which usually causes less surge. The bigger the watt rating, the bigger the capacitors become, resulting in more surge. The main purpose of this protection is to control how quickly the capacitors charge.
Watt rating - but
SIP Protection
have all line-ups of Chieftec from 500 to 1000W.
Also, I think it's MSI PSU, on the startup have 115-150W+ inrush surge, which isn't ok?* (could be wrong)
"tripping the power breaker in your house" so it's more protection of house power breakers, not pc system ? it's "180" from what I thought. 😶
