The W1 series is the same junk don't buy a low quality power supply.

No, most likely not. It would run but you're pushing it to the max, which isn't ideal at all and could cause system instability. I would recommend a 550-650w power supply for a rig like that. 500W minimum.
65 Watt processor, 150. to 170 watt video card, might get 60 watts for everything else, with the overclock about a 300 Watt PC.
That power supply is low quality (420 watts on the 12 volt rail rated at a very low 30C) so about 75% of its rated output.
I would not use it if it was a high quality 450 watt power supply I would say yes but not with the low quality,
