550w PSU 80 gold enough for this config?

[cPilot]

Hello!
Im looking to upgrade my current PC, I have a i5 4440 + gtx 1070 and a 550w PSU EVGA GD 80 gold, I've been using this PSU for a year and a half.

I want to buy a i7 10700 and a 3070, but im kinda scared of the wattage of my current PSU. Will 550w be enough considering its 80 gold certified? (It has 2x 8pin(6+2) pcie connectors as well)

Im attaching pictures of the PSU box with some info, if that helps

Thanks in advance

80+ certification is not a measure of quality.

 

You might be able to get by with that PSU but I think it would be well outside its efficiency sweet spot. Nvidia recommends at least a 650W PSU for the 3070, and while usually those recommendations are very conservative to make a safe margin for people who buy crap PSU's that don't actually make their rated wattage, the Ampere cards are known to have "spiky" power draw.

 

I would get a new, well-reviewed 650W or better unit.

Thanks for the info

So considering those "spikes" in consumption, I should not take into consideration youtube videos that say the power consumption goes up to 430w max? Good PSU's are kinda rare and probably twice as expensive where I live, I really want to make sure I NEED a new PSU, you know? Can those spikes pass the +100w I have left?

you need a new psu. thats a 550w c teir unit, a 3070 has been known to take down some bteir 800+w units. 

 

DO NOT skimp on your psu. Take a cpu spec lower before getting a worse psu.

Well... I dont have a choice then, what would you recommend? +650w? My problem is still going to be getting something out of the tier list, first I have to actually find someone who sells those. It sucks.

The teir list is bassically every branded PSU at this point.

I'd look for a Corsair RM unit, 650watt or above
