750w vs 850w psu?

[Jade]

So im building a new PC (7800x3D, 7800xt), pc part picker says that 750w version is completely fine for this build. Corsair RM750x is currently 44% off on Amazon Ger. Is it worth to spend more for the 850w version or it wont make a huge difference in case of any future upgrades?
And the 2nd question is Asus TUF Gaming psu any good compared to Corsair? Its cheaper than Corsair RM.
Thanks everyone

750w but 650w will be enough

When I build a PC 12 year ago I used a 1000 watts, still using it today. Don’t go small, don’t go cheap. One less thing to question if you’re PC ever crashes. I like over kill psu, so I would be 1000w minimum. 650w lmao

750W is fine for this build but may not be enough in the future if you want to upgrade the graphics card.

Brand new top-of-the-line I would go with a 1000w Gold/Platinum, mid-tier shelf a 850w, and bottom teir new PC 650/750w and the reason is that the larger capacity ones are just built better and go with a good brand, Corsair - EVGA are to name a couple and warranty length can be a tell-tale sign of quality with PSU's - higher the warranty length (in years) the more plausible the PSU will out last the warranty and vice-versa my best EVGA came with a 10-year warranty while the main one I use daily came with an 8-year warranty (one year to go w/o issues) so my choice is EVGA just because of present/past experiences.

A 1000 watt PSU is not needed....but going with a 850 means you have head room.....as for corsair i would never buy them again.....i have (2) CX650M sitting on the shelf dead.....super flower or seasonic or bequiet! are better power supplies.....

real A tier PSU's are going to be closer to 200 dollars for 850 watt......like this Bequiet dark power 13

check out the list of PSU's by tier and pick one in the A group if the budget allows it......

I got my 1000w EVGA for $85 because during December they have deep discounts to get all the years models off the line for the newer models but to go with a larger PSU with like a 10-year+ warranty @ 1000w, the PSU could be used in not one but TWO new systems within those 10-15 years dependent on the current/future wattage climate.

But do not listen to me, Captain OP, because I only have one of the most reliable and long-lasting OC PC systems out there today yet people treat me like second-class here.

Corsair CX is their cheap series. RM and RMx are usually fine.

and i bet money its not a A tier PSU.....my EVGA G3 750watt was 140 bucks on sale and is a A tier PSU......it was down from 180.....and FYI i have a 650 watt PSU that is over 12 years old now....did not need a 1000 watt PSU to use a PSU for over a decade.....

my current PSU has seen 3 motherboards and 4 GPU's......on a 750watt......850 for this guy will be fine......

[_I_]

using a higher wattage psu is fine
as long as its more than what the system needs

over by 100% is good, since the psu will have lot of overhead, and it will also be in a much more efficient range

a psu being stressed at 90+% is not good for it, it will make more heat and be less efficient
