Epilogue
The Sharkoon Rebel P20 1200W is a decently performing PSU that will not empty your wallet. Given its specifications and build quality, it is sold at a fair price. It is ATX v3.1 compliant and Cybenetics Platinum rated in efficiency at both voltage inputs. It also has a Cybenetics Standard ++ noise rating, meaning you won’t bother the neighbors if you push it to the max. In fact, up to 690W loads, the PSU operates quietly, keeping its noise output below 25 dBA, and with a lower than 65W combined load on the minor rails, noise is below 10 dBA at up to 690W at 12V. Despite its compact dimensions, the fan speed profile is not aggressive, and these help the large heat sinks that Andyson used to handle the thermal loads. In most modern PSUs, the heat sinks are pretty small, requiring aggressive fan speed profiles at high loads.
The load regulation is tight at 12V, ripple suppression is also good, and the 12V rail’s transient response in ATX v3.1 test scenarios is pretty good. The 3.3V rail mostly needs tuning for tighter load regulation and better transient response, but this rail is not heavily used. The average efficiency is high enough; Andyson should push it above 70% thought, at a 2% load, to meet the ATX spec’s relevant recommendation. The APFC converter also needs tuning for higher PF readings, especially at 230V. Moreover, the power consumption on standby at the same voltage input should be below 0.1W.
Overall, the Rebel P20 1200W has a fair price, offering decent performance. Some of you might frown upon the 2-year warranty that Sharkoon offers, but I won’t since I am sick and tired of other brands’ totally unrealistic warranty periods. This is why I no longer list the warranty period in my pros or cons lists. Long warranties offer more problems than solutions; ultimately, they do not benefit consumers and the brands that offer them. You buy a new car, get a 5-6 years warranty, the best, and buy a new PSU and ask for ten or more! A PC part whose life is mainly dependent on the electricity network’s quality, so it is super easy for a brand to reject your RMA, and for a good reason! It is way better to have normal and not marketing-oriented warranty periods and be treated better, and the product prices won’t also be affected.

You help me a lot by using my affiliate links, which don’t increase the product’s price. I get a commission from Amazon every time you do it, which can make a difference for me, especially now that I am on my own, working exclusively for my media and not for someone else.

It is worth adding to the disadvantages only a 2-year warranty. That’s funny.
Nope, I won’t fall in the warranty pit ever again. Only if it is one year I will mention it.
