Can my LC Power LC420H-12 power a rx 580 wit a single 8 pin input

[benchmarkacc12]

I want to to buy a rx 580 but i dont know if my psu has the needed 8pin connector. 450 watt should be enough so iam not woried about that part i just dont know if mh psu has the right psu connector and if it doesnt have it what can i do to solve the problem. I will buy a new psu in the future and iam not gona overclock the rx 580.

If the PSU doe not have the needed connector then it may not actually have the power distributed where you need it. ie - 12v lines.
Link us a picture of your PSU's label where it shows the breakdown of the power distribution please.

Version 1.3 or Version 2.31?

I would say a big NO, to either. If you had a decent single-rail PSU that could output anywhere near 420W on the 12V line, we might be able to banter back and forth, but since V1.3 only does 180W on the single 12V rail and V2.31 is a dual rail 132W/96W I'd be surprised if anyone tells you you don't have to get a new PSU.

What country are you in?

The netherlands. i was thinking about buying a cx550 gray. A lot of people reccomend that psu and it has the right connector.

Not sure what the "grey" part entails (maybe opposed to the older green models I suppose), but yes, the Corsair CX550 would be a good low cost choice.

Do NOT use your current PSU with new graphics card.
You are just asking for a lot of trouble.
Either buy them together, or get the PSU first and wait for the GPU. They will be cheaper again as more and more come out this year.
