Modern high efficiency PSUs should have no problem with this, because their active PFC limits input current. NTCs also reduce efficiency and don't work when toggling power, unless you add a relay to short it out. They're a hack.

if you're gonna short it out, you can just use a resistor though

You need to use an NTC that'll stay within power limit under load to avoid a fire hazard when the relay doesn't work; if you try to do the same with a normal resistor you need large and expensive power resistors.
