How much can a 550 watt 80+ Gold PSU handle?

[Sinister80s]

i got a Corsair RM550x and i was wondering if it could handle an upgrade to a GTX 1070. My CPU is a Ryzen 5 1600 btw.

On your average system the card requires you to have a 350~400 Watts power supply unit.

My opinion not enough. I run a 850w Corsair. More than covers every possible device internally including any USB external attached devices as well.
My GPU is a Nvidia GTX 1060 with 3 gig
System Power Supply
Minimum 400 W or greater system power supply with one 6-pin PCI Express

My aim is that the PSU will never go higher than 75% of max capacity.

it should be fine, brand/model are better to determine than its labeled wattage

psu calcs are pointless, always recommending something overkill

ryzen 5 1600 is about 65w
1070 is about 150w
<100w for the rest
+100w for overhead

a quality 450w is more than enough

It depends on all your other system components too, couldn't really say.

I doubt your system even pulls 350w under a heavy load, so you aren't even in the sweet spot for efficency as your draw is to low.

To the Op, your more than covered, I'd suggest you and everyone buys themselves a power meter, they cost about a tenner and will show just how little power you actually use.

As reference my 2 systems, custom loop sli 1080ti with i9 7900x all heavily overclocked pulls between 750 and 850w from the wall, so at 90% efficency it actually uses 675-765w.

My other rig a 2080ti with a 9900k with mild overclocks pulls around 440w from the wall so uses around 400w.

Needless to say, low and mid range kit doesn't pull nearly as much power.
