[SOLVED] Is 750w psu enough headroom for 550w system?

[RCguitarist]

Putting together a new pc (been 8 years since i built my current one lol) and im doing a 12600k +3060ti setup. Pc parts picker estimates 450w of power needed for the entire pc setup. Is a Seasonic Focus plus gold 750w psu enough headroom (i wont be overclocking)? Or should i jump to the 850w version?

Also, is there going to be enough of a difference in my electric bill to justify the $20 extra of going to the platinum rated version of this psu?

Depends on whether you plan on upgrading that 3060ti in the next couple of years. With higher power 30 series cards, I'd probably swerve the Seasonics at 850w and go for a Corsair RM or RMX series at that wattage.

But like I say, if you do plan on jumping to a higher power card, buy enough wattage and quality now.

I've seen some Focus Plus Gold trip with a 3060 Ti. There must be something better available for a comparable price than Seasonic. Any be quiet! Straight Power 11, Corsair RMx, Bitfenix Whisper, Enermax Revolution D.F., EVGA Supernova G6, Fractal Design ION+, Super Flower Leadex III Gold, Thermaltake GF1 PE or XPG Core Reactor available?

Are the corsiar rmx psu's that much better than the seasonics? My lean toward seasonic is that my current build has ran flawlessly on the seasonic it has in it for 8+ years. But brands can change over time, so im open.

Yes. All the above listed PSUs are better than any Seasonic branded PSU. The EVGA G6 is a Seasonic inside which is the best Seasonic OEM PSU. It has an improved Seasonic Focus platform.

I primarily use Seasonic and I think you’d be OK with Focus Gold 750. As others have noted, a focus gold 850 would leave upgrade capacity.

I’m currently using a Focus Gold 850 on my 5950x which draws over 200 watts with OC and 3080 ti at stock drawing 350 watts.

Some Seasonic Prime/Platinum units have had issues with 3080/3090 card spike power demands - I’d stay with Gold.

Why spend 150 bucks when https://pcpartpicker.com/product/CQ...fied-fully-modular-atx-power-supply-erf850ewt is 33% cheaper?
Or https://pcpartpicker.com/product/dn...-fully-modular-atx-power-supply-cp-9020188-na with braided cables. They're a lot easier to handle than the cables with incable caps of the black RMx.
https://pcpartpicker.com/product/Kq...fully-modular-atx-power-supply-220-g6-0850-x1 is also amazingly priced at Amazon.
