I am considering to switch to 9900k + 2080 Ti. I think I will overclock both GPU and CPU. I have a Seasonic 650w Focus+. Can my PSU handle it?

My build will be like:

i9 9900k
RTX 2080 Ti
G.SKILL Trident Z 3200MHz C14
WD 1 TB Black + Samsung 850 Evo 1TB SSD + Samsung 850 Evo 250GB SSD
Nzxt Kraken x62
Soundblaster Z + Sennheiser GAME ZERO
2 System fans with RGB with Nzxt Hue+ (PC Lighting control device)
G502 Hero + Razer Blackwidow Keyboard

Honestly if I have the cash  I have always erred on the side of having more power than I need..

I'd rather save the money if I can. I don't want to squander money if Seasonic 650W is enough because I already have a 650W PSU and bought it 1 year ago.

I dont know if your 650W PSU can hande it maybe when you dont OC it but...u are buying high end components for god knows how much money there, and then u want to "Safe Money" on a new PSU? The only thing that could ruin your whole system of thousand of dollar's.

 

I would say dont Safe on a new PSU look for the PSU tier list here on the forum and search for the T1 PSU you can get with i would say 1000W Gold Rated maybe, i dont now much about PSU's otherwise.

I am not sure if you understood it correctly. I already have a "Seasonic 650W Focus Plus". Seasonic is a top-tier brand.

I know bad brands might ruin your whole system but this is a Seasonic PSU. Would my Seasonic PSU ruin my system if the power consumption is close to 650W or above 650W? I don't think so. It'd just shut down the system.

I have no idea how much my new system will consume. So, if it consumes less than 650W, it makes no sense to me to buy a new PSU.

well...most 3rd party RTX 2080ti pull around 250W from the wall and can go up to around 300W when fully overclocked.

9900K at stock under full load is around 200W and will jump to 250W or so once overclocked.

 

So right there and then if you overclock both you're looking at 500 to 550W for the CPU and GPU...that won't leave much headroom once you factor in memory, motherboard, SSD, leds, fans, CPu cooler (pump) etc...those things will each pull like 5W or so each...so i would say it's ''enough'' ...barely...but not quite...IMHO you'd be much better to buy a EVGA 750 or 850 G3 or G2 powersupply...those usually cost around 100$US which is very little compared to the price of the hardware that will be hooked to the unit...i wouldn't risk it personally.

Should be fine. It's a good-quality unit, with enough wattage. It's not like the computer would instantly explode if too much power was drawn anyways. It would just keep turning off under load. If that happens, then upgrade (obviously) but it shouldn't

what usually happen first when your PSU isn't quite up to the task is not that the computer will turn off it's that the unit will get hot and overheat and the fan on the unit will start to scream it's ass...i had this happen to me when i was using a 550W to power a 980ti/4770K RIG it was a good unit (XFX XTR 550W gold/ built by seasonic) everything was fine until about 10 or 15 minutes into a BF1 game and then the fan would go crazy for 30 sec, then slow down 15sec, then back to airplane mode for another 40 sec etc....so i had to upgrade it...i think this is what can and probably will happen on this rig.

This sounds like what would happen if the PSU was right at its limit. If you were to pass the limit, the computer would have no other option but to shut down.
