OMG what watt

[Vintage GT75]

Just a few days away from purchasing the rest of my build.  I'm hoping to get the best efficiency from my psu but the mammoth amount of advice, figures and options has made this difficult.

 

Mobo: Asus z490 Hero

CPU: 10700k between 4.9 & 5.1

Kracken X73 aio

6 x 140mm case fans

1 x ssd

1 x 2080 super - (3000 series eventually)

Case: Fractal Meshify s2 

1 x USB mic (blue yeti x)

1 x headphones AKG712 pro

 

For gaming only usage between 8 and 12 hours per day.

 

What wattage and or psu to purchase?

With a targeted best efficiency.

 

EDIT: Budget for psu £$250

Monitor: 240hz @1080p

 

Aiming for 240 fps where I can.

What's your budget for the power supply?

 

Also, are you set on a 10700K and Maximus XII Hero? You could save a good bit of money off of these without losing virtually any gaming performance whatsoever.

With that CPU, aim for a 600W unit. At those clocks, it easily pulls 200W and up. The 2080S is another 250-300W

True. If he buys a 3700X instead ,it would be cheaper, run cooler and use basically half the power as the 3700X is far more efficient than the 10700K for what is basically the same performance. He'd also save money on the cooler since even the stock cooler is plenty for AMD

Disappointingly I was actually going to suggest a 10600K haha. 

That being said, if OP plans on gaming at 1440p or higher, I agree that it'd probably make more sense to go with AMD instead.

I personally can't recommend the 10600K. In games it's only 2-3% ahead of the 3700X at 1080 (even less at 1440) and the lost performance and higher power/heat are just hard to swallow.

The difference between the max efficiency and the min efficiency is gonna be like 2%, at most, once you're above 10% load on the PSU. You would not be able to notice the difference on your power bill.

Incase this makes a difference, I suspect it will.

 

Monitor 240hz @ 1080p

Will this depend on the psu performance?

Not really, once you're in the ranges of the 80+ rating the efficiency is very consistent.

For the power supply, I'd recommend either a Corsair RM550x/650x or a Straight Power 11 550W/650W, or if you plan on upgrading to a 10900K and hammering it, a Straight Power 11 750W.

 

Also, for the CPU and motherboard, I'd instead get a 10600K and either a Z490 Unify (unless you need the iGPU) or Strix Z490-E, or even a Z490 Gaming Edge WIFI which is cheaper and still gets the job done, even with a 10900K.

Since that dude said 600W(not 550 or 650), there arent many choices out there. Corsair SF600 or Pure Power 11 CM 600W are in your budget.

I like the features the Hero brings to the table also the overall performance benchmarks as per Kitguru including temps.  The Hero appears to have the "can't go wrong" reputation which from a sub par experienced person makes me feel better.

I originally had my sights on the 10900k but yeah overpriced and constant pre order.  After researching countless benchmarks, and yes I'm one of those FPS snobs unfortunately, the 10700k seems like the way to go.

Wait for Zen 3 then if you're an FPS snob. You'll be hating yourself in two months otherwise. I can't reveal much but the money will feel wasted if you but now and want the best for gaming.

Is he limited to 600w? No.

The wattage being suggested and recommended appears to be significantly lower than I anticipated.

So should I really just aim for approximately 200watts higher than the total of my individual parts and ignore the efficiency maths?  I feel I may have either read into psu purchasing too much or I'm falling for inaccurate information.

Thank you for the advice.

This is playing a huge roll in my decision making and after many months of waiting and using my current rig ( really bad) I can't wait any longer.

Well, a system with a 10600K and 2080 Super will pull around 425W max at full 100% load. While gaming, that number will be lower.

A good 550W PSU will be more than enough for pretty much any single-GPU gaming setup today. The actual quality of the power supply's components though is a lot more important than the advertised wattage after a certain point, and on that note, the 80+ rating doesn't necessarily correlate directly with a PSU's quality (as in not all 80+ Gold rated units for example are super high quality).

 

The 10900K on the other hand is the odd one out when it comes to current-gen CPUs, since it just pulls so much current when overclocked. It's pretty much the only consumer CPU where I'd actually recommend a 650/750W unit, when paired with a high-end GPU like the 2080 Super which will pull around 250W by itself.

 

If you're stuck on what actual model power supply to get or if the Corsair RMx or be quiet! Straight Power 11 are out of stock locally for you, the forum's PSU tier list gives you a decent general idea of what to buy and what to avoid:

For a Z490 build with a 2080 Super, I'd personally only consider Tier A units that aren't written in grey.

Fabulous.

Well, that's your call. But the 4700X will be about ~15-21% faster than the 10700K in everything, including single-threaded applications. So keep in mind that after 2 months the i7 10700K sill be slower than the lower midrange Ryzen 5 models

I really can't divulge my sources but it's not looking good at all for Intel in September. If you can't wait, get a 3300X and X570 board and upgrade to Zen 3 in two months.
