It's 126A , that's current
So assuming it's 126A x 1.3V = 163.8W (call it 163W) without a heatsink , no safety allowances adjusting for RDS(on) vs voltage and such

(A real PCB isn't going to be giving 1 sq in per mosfet)

The Fairchild parts are 35A with 100°C T_Case not T_ambient, it's not the same



Granted the K6 is likely more able to keep under those temperatures due to the added heatpipe.

There's a ~ 4% difference in efficiency (~88% vs ~92%) ; while the Gigabyte Gaming 7's Intersil Powerstage parts are over 92% efficient

I am kind of an Asus maximus fanboy and will take into consideration the aesthetics too in this decision (I am ashamed to say this, but its true that I want to build something beautiful to see through my tempered glass window of the Phanteks enthoo pro M).

However I am also a realist and there are 2 things that make me want to get a cheaper/v4m board :
1) Pairing a 8600k with an expensive board is stupid, as you will end up in a worse setup than pairing an 8700k with a cheap board, despite the possibly a little higher OC.
2) This platform is already dead within less than a year when Z390 comes and I will upgrade to an 9600k, so the term "investment" does not apply for the Z370 motherboards.

So I am looking at what to get that will not limit my OC (I want 5ghz 24/7 at least, and hopefully 5.2 if sillicon god allows me to), remains sensibly priced (over 200 euros is a no-go for the above reasons) and satisfies me in the looks department.

So, having read some stuff here, its obvious that the Asrocks Extreme4 and Fatality K6 are the bargain boards. Unfortunately, besides my Asus fanboyism, Asrock has changed local warranty to 2 years (down from 3) something which annoys me.
MSI also seems decent with the Pro carbon and M5, but I got very bad experiences with the brand in the past (have sweared to only buy GPUs from them )

So going to the Asus parts I want your help.
1) The TUF are crap as is obvious
2) The Prime and Strix E/F seem to have the same 10 VRM setup, is that right?
3) I really like the looks of the Strix F board and gives you a taste of the Maximus flavour that I cant afford for the above reasons. Its price however is higher locally than it should be (about 225 euros when the Fatality is 188 and Extreme4 is 165). Assuming it goes down to a sensible 195-200 euros, is there something that this board lacks in OC capability from the Asrocks?
4) If I cant get the Strix cheaper, the Prime is at ~180 euros currently. Forgetting the ROG branding and looks, is there anything this misses in OC capability/VRM from the Strix and the Asrocks?
I believe you'll be fine with the STRIX-E/F , Z370-A, or Asrock boards higher than the Extreme4. The i5-8600k isn't going to consume the extra wattage from hyperthreading.

The STRIX-E/F and Z370-A don't use the exact same parts. Similar in efficiency and layout, but not the same.

We're collectively not sure on the MSI boards. The MSI Z370 M5 boards have the potential to be on par with the STRIX-F (depends on doubling scheme) but I think the plastic over the Pro Carbon is going to hold it back. I can't recommend either due to uncertainty and also because I hate Killer LAN as the only LAN.

I've seen at least one report of a user on a "do not buy board" ( Gigabyte Z370 HD3P) hitting 80ºC Prime95 blend at mere 1.21V with i5-8600k @4.8GHz, so it reinforces the idea that board belongs there in the do not buy section.

Given the pricing there, what would you take?

P.s. I will be using a D14 SE2011 for the moment, then a EK Waterblock (Not Mono)

In that event I'd go with either the hero or save the money and pick up the Taichi.

Besides, both the Hero and the Taichi are very good boards. Asus rog uefi is more polished and especially on the Apex is state of the art and allows a quicker and smoother overclock process (on z270 it was really the best).
Gigabyte is quite reliable but there is some vrm issue on SOME gaming 7 boards - poor contact from the heatsinks it seems and that put me off, until is proven that tgey can just be tightened with a screwdriver.
On Asrock boards lesser than the Taichi instead has been reported the use of two different vrm parts, which is unethical.

I tell you what, I think I'm just going to wait until the Z390 chipset is released. I'll just replace my i5 6600K with a i7 7700K, since the Gigabyte Z170 Gaming 6 does support it from a BIOS update a few months ago. That'll hold me over until the Z390.

On the right is the Z390 features

After faffing about with the Gigabyte Gaming 7 for the weekend, I've come to the conclusions that:
  1. The UEFI could use more work, and the dual BIOS works until it swaps between the two every time there's a hard lock and you have to remember what settings the other BIOS had.
  2. VRM cooling is ok as long as there's some air flow around the area and the heatsink is firmly screwed in. See photo below for my setup.
  3. The IT8686E sensor reading is unreliable at all times and goes completely nuts when the system is under load.
  4. The IT8792E Vcore seems to match VID + DVID, this one doesn't provide all the readings.
  5. Voltage under load (according to IT8792E) is very stable within 20mV of VID + DVID with Turbo LLC.
  6. My 8700K needs 1.375-1.4V for 5GHz AVX



This board has about 3mm of clearance between the VRM heatsink and the 140mm fan in a Define S when using a radiator

Seems fine. What abour your VRM temps with that setup and if You remember without the fan ? How did You remove i/o plastic case near the vrm ?
I can replace my aorus or buy taichi/fatal1ity/hero. Stil lwaiting for prices from supplier but don't know what exactly to buy now...
