Long term no, but folks that got their units EARLY for the first day or perhaps two?

One thing to keep in mind on the Vega pricing - apples to oranges.
3 months ago the ONLY Vega cards available were reference design.
Today the only Vega cards available are 3'd party cards, with better cooling and SHOULD be higher performance.

*3* 8-pin power connectors on some of them though is crazy.

The only place in the Continental US that can argue for high rates with the WORST California rates are in the New England states.
California does see a lot of variation on rates - the large urban areas like San Diego and LA are high but not insanely so, while the rural areas like the mountainous heavy wooded far Northern part of the state tend to be VERY high rates.

It says a lot that a lot of the hydro power produced in Central Washington is sold all the way to California - and that's it's STILL cheaper despite transmission costs than they can manage locally in most of the state.

The Zotac "mini" cards are smaller than most others - ballpark 8" long where the Gigabyte "ITX" and MSI "Aero" shorty cards are less than 7" (EVGA also makes shortie cards but nothing higher than a 1060) and most cards are 10" more or less.

This limits how much heat sink CAN be put on the cards, so they don't cool quite as well as "full length" cards of the same GPU model generally do, though they DO cool better than some full-size BLOWER design cards do.

 It would appear, based on REPUTABLE quotes, that China intends to get serious about regulating exchanges in an attempt to restrict or stop "capitol flight", but they don't care about mining itself except where it is getting major breaks on pricing from areas that used to have electric shortages - they HAVE said they intend to eliminate sweetheart deals in such cases.
I suspect they LIKE Bitmain for pulling a lot of external capitol INTO the country - but dislike how much of that Bitmain is using to pay for their chips to TSMC.

 Reality check here.
 You're trusting stuff CNN publishes?

 ROFLMAOSC!!!!!!!

 It has ZERO effect on GPU mining, even when it's doing the actual drive reads for the active "mining", unless you are trying to run it on a 1 or 2 core CPU - then the effect is small and short-lived.

 SMR drives like the Seagate Archive line are pretty much PERFECT for BURST - you "plot" the drive once, and after that it's all READS from data that does not change.

 USB flash drives work, but WAY BLOODY EXPENSIVE per TB - not cost effective at all.
 The only machines I did THAT on were running small LINUX installations on "oversized" USB drives and I figured "might as well use the extra space for SOMETHING".

 HDD on a "per TB" basis STILL blow away any flash drive.

 If you manage to kill a GPU in less than 5 years of mining on it, you're doing it WRONG.

 I have quite a few cards that have been mining (or running the DNet client, which is also crypto work and JUST as intensive to the GPU) since the LITECOIN GPU mining days in 2013/2014 that are STILL mining away today.

 Do quit spreading the "mining kills cards fast" FUD lies.

 Haven't found a more efficient option yet, though all but 1 of the 1070 ti models I have to date can MATCH my EVGA SC 1070 ti cards on efficiency, and that one (ASUS blower model) was very close.

 It's the SAME GPU in the card, with a low power setting that makes cooling differences mostly a non-issue.

 2 x 750 are PLENTY for 8 1070 ti cards running at EFFICIENT settings.
 An 850 is enough for *5* of them at efficient settings with a fair bit of headroom.

 The issue is a combination of 4 VGA + 4 SATA/Perph slots on the PS, NOT just the VGA slots (which have DUAL power cables avalable).

 Should be able to run *5* rigs if they are only pulling 1050 watts each.

 Extension cords to run a miner = VERY BAD idea, even the heavy-duty ones tend to heat up a lot at the connections.

 EVGA 1080 FTW cards are somewhat higher TDP than "normal" for 1080 cards - 215 watts or some such IIRC, so at 70% they're pulling 150 watts or so per card (which would be 83% on many other 1080 models).
 Gigabyte AORUS 1080 ti is 250 watts TDP, at 65% they're pulling 163 watts or so per card.

 THAT is why the gap is so small.

 Newegg has been high priced on the AMD side at least since this summer.
 Just not *AS* high priced as some of the gougers.

 SIA's algorithm isn't supported by any of the Baikal miners.
 That "Obelisk" group announced a SIA miner, but don't think it's actually shown up yet - if it EVER does.

 The profitability train is going to run into a major wreck called "Ethereum move to Proof of Stake" at some point, currently intended for late this year IIRC.

 Gonna be a BIG shakeout when that happens, since there are more cards mining Ethereum THAN ALL OTHER COINS COMBINED and that huge hoard of GPUs is all going to be looking for new homes at the SAME time.

Every BURST calculator in existence is optimistic on earnings, due to a flaw in how the "network size" is calculated.
Figure you'll pull 60% or so of the "calculated" value as that's about what the ACTUAL returns average - if you can find a pool that stays up reliably for more than a week at a time any more.

 The most efficient settings for the 1070 ti (NOT THE 1070) put the TDP at about 104 watts (slightly under 60%), which is only 416 watts.
 My 5-card "mix of 1070/1070ti/1080" rigs run all the cards in the 104-110 watt range and only pull 700 watts AT THE WALL despite using somewhat power hungry AMD 8320e CPUs for the most part - which is going to be more like 640 watts out of the PS itself (I do run them on Seasonic X-850 PS for the most part, one on a SS-860, as those have enough CONNECTIONS that I don't need to use splitters - but from a "handle the power" standpoint the EVGA G2/P2/T2 series would be fine).

 A 750 should easily handle an entire 4 card rig if running the cards at EFFICIENT settings, much less splitting an 8-card rig between 2 of the PS.

 Don't run the SSD on a power supply seperate from the MB - power draw is too low and too likely to do ground loops.
 Fans on the second PS make perfect sense.

I haven't seen any proof of stake coin that offered 4% per year (INVESTMENT returns not included).

 But I would also consider 8% a joke, given the high inherent risk of a PoS coin inherent REQUIREMENT that you have your wallet online all the time to stake with.

You can, just don't expect big results.

If you are running the cards at efficient settings, run 4 card + risers from one PS, run MB/etc + 4 other cards from the other PS.

You have enough connections to do that easily - 5 cards per is problematical as there aren't enough ports on the PS to go around without doing SOME sort of splitter stuff.
