650w suitable enough?

[Laughingman91]

Ho folks, about to purchase a i9 9900k and a 2080ti build with a h150i AIO, an an elgato capture card.
BeQuiet Dark Base RGB 700 case.

The build configurator provides options for lower power PSU's - and I figured even with modern low powered tech, a 550w won't cut the mustard.

650w would seem like a smart choice to my uninformed ignorance, but is an 850w overkill?

 

I'm thinking to take the 4 HDD's from my current build (2009) and have them in an external enclosure which I expect would have it's own power brick.

But would the system take the extra 4 if I chose to fit them inside the case? Plus a blu ray drive?
Never investigated the power side of things, hoping some brainbox can clue me in. Cheers!

Hello, a 650w power supply is the bare minimum for this spec system, you may wish to consider upgrading to an 850w power supply due to the power consumption of the i9-9900k and the 2080Ti being much greater than that of previous generation processors and graphics cards, however, a 650w should be able to pull the weight of both of these.

If your going to spend all that money why not get a nice power supply too?  I'd go for 850W or more.  And 80+ Gold at least (preferably platinum)

650w is plenty.  850w isn't necessarily overkill, because it doesn't adversly affect you if you have a 850w psu, but you should be fine with 650w.

more wattage =/= "nicer" psu.  Also a better efficiency doesn't always mean better. @Laughingman91 an evga g3 or seasonic focus gold + (or a corsair rm650x if you want to spend more money) are all great.

This.

 

Just because it says "650W" doesn't mean it won't kill your PC in a year's time.. or that it can even put out 650W (not like there's any "PSU governing body" to make sure labels are honest.)

 

So just be careful what 650W you get.  Because a GOOD QUALITY 650W is more than enough.

Seeing as you're buying overclocking parts one can presume you will be overclocking? In that case I would suggest a bigger 850w, but if you're not (don't know why you wouldn't with that hardware) you could try undervolting the CPU to save some power and get a half decent 650w, or even just split the difference and get something like my Corsair rm750?

Even under synthetic load with peak turbo on every core his system would only draw around 420w... that leaves him 200w to play with under synthetic load which doesn't actually happen in any real world scenario. While gaming for example, even in an intensive game, he'd be more around 350w max. That leaves him with 300w of headroom, there is no way he's going to double his power consumption overclocking, especially with his cooling setup.

650w is plenty, just make sure you pick a high quality PSU:

Oh okay, id have thought it would've drawn more, but I'm aware I don't know everything so

I really don't think he needs 850W

 

doing the math the 9900K is a 250W CPU and the 1080 ti is a 350W GPU, so you are looking at 600W for those two components (when overclocked and maxed out) the other stuff doesn't draw that much, keep in mind that I am talking about a 100% cpu/gpu scenario.

 

And 80+ gold/platinum is very ambiguous, 80+ isn't a standard for quality

People go mad with wattage, 650-750W is fine

 

Focus on quality not wattage
