i'm cooling the r7 and gpu with a custom loop, with a radiator on top to pull out hot air. not sure if that helps much with cooling the vrm though.
taichi is what i got my eye on but asrock isn't in the market yet and rep isn't sure if or when they are coming.

local prices:
Asus Prime X370 Pro $196.85
Asus ROG Crosshair 6 Hero $341.90
MSI X370 Xpower Gaming Titanium $326.56
Gigabyte Aorus AX370 Gaming 5 $237.10
Gigabyte Aorus AX370 Gaming K7 $264.99

Holy hell where do you live? All those prices seem outrageous.

I think best advice here is to wait for price gouging to subside...

south east asia.
generally, distributors and retailers got a $30-50 mark up on pretty much anything they sell here. it gets worst for premium parts like the 1080Ti reference cards, that sells for $843.37.

yeah, am not in a hurry with those prices.

Asus Ch6 Beta bios has done some amazing things.
I honestly think I could push the frequency higher

Is that fully stable? Which RAM kit are you using?

Budget boards now. they all have corner's cut to improve the bottom line and that's true for all vendors where it's buyer beware. . Notorious failures? Can't find any.
1700 at 4.3 on air? Still a happy chip at a more conservative clock. hmm, interesting. on their 'official' facebook biostar page. Didn't validate it manually. Pity, would have been nice to see up there.

Fine, I will put it simply - Biostar has not publicly released RMA statistics to date. Based on available statistics, ASUS, MSI, ASRock, and Gigabyte (in no specific order) will be more reliable.

You can find reported stats for the aforementioned 4 vendors. If you can find any contrsdictory data on BIOSTAR, then please post it.

That is a very high quality PSU. . Still overkill, but I could see a reason to buy a PSU like that a couple of years ago. Power usage trending hadn't really started to fall, so this would give efficiency and future proof you.

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story6&reid=398

(anyone looking for a *GOOD* PSU should be checking JohnnyGuru before buying)

If I was looking today, I would only really consider a PSU like this (1200w) for a server (something like a large NAS server) where it may sit idle for a while but spinning up all disks would create a surge in power need (you maintain efficiency on both ends). A PSU like this would be perfect for a build like that. But the 850W would be hard to argue against given it's efficiency and 7 year warranty.

If you're referring to the ubiquitous Hardware.fr report, it's not a case of manufacturers releasing statistics, it's a compilation prepared by a French hardware retailer. That's why, for example, EVGA doesn't show up for consistently for VGA RMA numbers.

Hardware.fr is part of LDLC, the largest seller of computer components in France.

That is only one. There are some other reports online, but they tend to be older (and sources not always clearly sited). The volume used in the Hardware.fr is too small in my opinion to be a reliable guide. A couple of hundred units is pretty insignificant. From some posts I could find, it appears there are internal industry reports available but those are restricted (NDA's).

There are also reviews on NewEgg, Amazon, etc. But again, I take those with a grain of salt because people are more likely to complain than to praise, and they can also be VERY subjective. Your MB isn't scoring that high right now on NewEgg, but when I read the specifics only a couple seemed to be real issues. Most were subjective complaints about the BIOS or compatibility and I throw those out as those can apply to ANY AM4 board right now.

I'm really not trying to be biased. There are a lot of people posting who really LOVE their Biostar boards (not AM4-specific, just from general searches), and many others who swear they are not good. I can't find any statistics that are viable one way or the other, so I suspect the truth is somewhere in-between. They probably make a lot of very good boards, and probably had issues at one time or another with some of their models.

Same can be said of MSI. Seems MSI had issues with their Z170A line of boards, but that data is from Hardware.fr, which I already gave my opinion on. Sample size is a bit small, but the numbers still jumped out. But those boards used "better" VRMs, which again begs the question as to how much of an impact just the VRMs have on reliability. All X99 boards as well as AMD 990 boards had higher than average failure rates and those aren't cheap boards. So this does beg the question as to whether there is any practical way to gauge reliability on a new MB short of waiting until they have been out a year or so...it really doesn't seem like brand, VRMs, or anything else is very suitable as a *predictor* of reliability as a number of "quality" brands/models have succumb to higher than normal failure rates.

If Ryzen had come out a few years ago, Biostar probably would have landed on my short list. It's hard to deny the value they offer. I had bought MSI and ECS boards years ago when they were up-and-coming and less well known. My criteria was just different this time around.

Problem is that citing any statistics that have 0 data about a product line and stating the ones that enjoy the luxury of available data are going to be more reliable. .. thumbsdownsmileyanim.gif continues to add to the FUD.
Internet searches will turn up yet another, unjustified!, negative hit on their reliability. From THIS thread.
