It will depend on the exact make/model of the 300W PSU. But RAM OC'ing isn't that demanding; not like a processor.
Hello, thanks for your reply. The model of PSU is from the case Antryx Xtreme Slim xs-100.
Oh, I see. It came with the pre-built system. Sorry, I was thinking it was a self-built machine. Yes, that PSU has a decent 300W
nameplate rating. If you're using the XMP to OC, you should be fine. If you are manually OC'ing the RAM, go easy on the voltage increase. The motherboard has no heat sinks on the RAM VRM components.
And no CPU OC'ing, tho.
