Neither PSU are good really. What is your pc setup? normally a XFX 550W should be ok.

I'll be honest, I've never seen either of those power supplies o.O . My guess would be that your computer's combined wattage (cpu, ram, board, hard drives, and video card) is above 400w at load (in game for example). The 400w rating is typically for computers that do not have a dedicated graphics card or a low power one. What graphics card are you running?

The R9 270x is a mid-range card capable of drawing an average of 200-220w. According to spec sheets from AMD (for their reference card) the R9 270 and 270x require a minimum of 500w for a single card or 600w for dual cards. My guess would be when playing games on ultra you are pulling the referenced limit of 200w which is just too much for a 400w unit to handle. I'd upgrade ASAP :)  I am not sure about EU vendor availability but I'd try to go for a Corsair, EVGA, Seasonic, or Cooler Master unit with a minimum of 600w (just to be safe and allow for room to grow).

Corsair CX series aren't particularly good with the quality of their caps. You should choose a better quality like EVGA 600B or XFX 550W Core edition.
