More power ?

[espr3ss0]

I went by what pcpartpicker.com suggested but think it's wrong. https://pcpartpicker.com/list/n8yRQZ looking at Estimated Wattage says 524w but looking at the box of the Sapphire Radeon RX Vega 64 Nitro+'s https://www.amazon.co.uk/gp/product/B079QFF6CC/ref=ppx_yo_dt_b_asin_title_o03_s02?ie=UTF8&psc=1 says 850 or more. I've already got the PRIME Titanium Fanless 600w PSU, should I get more power ?

Would you overclock the GPU&CPU? Or stock on CPU& undervolt the GPU? Because, in latter case, 600w will be, though borderline, enough. Would rather opt for 650-750w if you'd happen to OC your hardware.

 

Btw, 99.999% of people recommend undervolting Vega& all AMD cards..

PCPP power estimator isn't that reliable, especially for high end parts like this. It will just show the TDP values as the power consumption and for parts like the i9 9900k there can be a big discrepancy between the TDP and actual power consumption.

You can find some power consumption figures for the Sapphire Radeon RX Vega 64 Nitro+ here at Tom's Hardware: https://www.tomshardware.com/reviews/sapphire-rx-vega-64-nitro,5388-6.html

Along with some power consumption tests for the i9 9900k https://www.tomshardware.com/reviews/intel-core-i9-9900k-9th-gen-cpu,5847-11.html

 

Looking at that I wouldn't recommend running Furmark and Prime95 at the same time

Gaming probably fine though as long as you aren't silly with the overclocks. I second @Vejnemojnen with undervolting the Vega64 if possible.

 

Do you already own the CPU & GPU or are you looking to buy them? I don't want to get too bogged down in recommending alternate build options - especially if you already own the parts - however there are some new CPUs and GPUs coming out this month that might be worth considering, and may be less of a concern with power consumption.

Not looking to over-clock the GPU but maybe the CPU to 4.2. I have all the parts already, btw what is Furmark ?

[espr3ss0]

After looking on https://seasonic.com/wattage-calculator I should go above 700w and found Corsair's AX860Wi. There is a vid by Linus for this product in 2012 so question is, is it outdated by now or still good ?

EVGA tech support recommends never running Furmark.  They claim it can damage cards.  Take that for what you will.

What is Furmark ?

 

So the newer but older analog design AX850 Titanium is more efficient but not able to monitor it ? Is there anything to consider if getting this ?
