Corsair VS 550 (2019) teardown and review. (Honest Review)
Here are my Personal Favorite Powersupplies for Computer
Antec VP450P (for Low Budget Users)
CoolerMaster MWE 550 V2 80+ White (Value for Money)
Corsair CX550 80+ Bronze (Cool dude users..)
Coolermaster MWE 750 Gold (Multiple GPU Users + Overclockers on tight Budget)
Deepcool DQ750 80+ Gold (My Personal Favorite all rounder)
here are additional information about this PSU...
1. Capacitors
Corsair VS 550 (2019) is using all Capacitors from Taiwan brand, Teapo specifically SC series rated at 105 degrees Celsius (SC series have average life of 3000 Hours at max rated temperature) while main Primary capacitor is from TC series by Teapo (expected life is 2500 hours at 85C).. they are not that great but still will do the job just fine....
2. Inductors
Corsair VS 550 (2019) is using Toroidal Iron powder core Inductors.. while PFC Inductor was on Ferrite Core Toroidal core Inductor.. I suspected VS550 PFC coil to produce Electromagnetic Interference because PFC coil gonna have to handle lots and lots of current.. as my experience and my experiments says.. that Inductor gonna emit Electromagnetic Noise..
3. Forward Topology
Corsair VS550 is using Dual forward Switch Topology.. which is good for efficiency, but due to high current switching.. MOSFets are prone to die and short out high current path and can result in blown up PSU.. so Proper Mosfets are required in this Topology.. but it is efficient only switching loss cause power loss..
4. Low Side Topology
Corsair VS550 is using BSDP(Barrier Shottky Diodes Packages) to Rectify DC and using Group Regulated 12V and 5V tied together and 3.3v Independent regulated Output Regulation.. which is very poor in maintaining Ripple-free stable voltage output...
That PSU have already Dead Diode package so, I cannot load test this PSU.. so sorry for that.
