choice between 3 psu

[magnus3142]

Hello,
I need to choose 1 of these 3 power supplies:
http://www.corsair.com/se-fi/rm-series-rm550-80-plus-gold-certified-power-supply-eu 75$
http://www.coolermaster.com/powersupply/modular-gm-series/g750m/ 75$
http://www.evga.com/Products/Product.aspx?pn=100-W1-0500-KR 55$

In my oppinion corsair is better but coolermaster has 200w more, and evga is cheaper. what u say?

It's a stupid idea to give an advice on a PSU without other parts known.
Any one of those is kind of mid-tier, nothing to choose from. If you're really, really can't buy anything better (plenty of choice for 75 bucks, mind you), I'd say Cooler Master 'cause of more power. Who knows what rig you have but I wouldn't put even Haswell + 970 on 550W Corsair, never mind EVGA one.
