Correction: that appears to be a full sized ATX psu, which has a 3.4 inch height which would mean total available GPU length would be an additional .9 inches brining it to at least 10.2 inches in available GPU room, still shy of what your 1070 requires... but that's my best guesstimation based upon what i'm seeing.

Well, an ITX motherboard is 6.7 inches by 6.7 inches

A SFX psu is 2.5 inches tall

it appears that your total available length in that case is about 9.2- 9.5 inches

That card is 11.73 inches long
1: My gut says that card will not likely fit in that case just going by length measurement alone.

2: there are many available cards that tend to carry ITX classifications, this tends to mean that they're single or double fan versions that are shorter in length and  often of semi standard PCIE height a 3060 may be a decent card that would offer mildly improved performance.

3: It is likely cheaper to buy a new ITX case. I would recommend the Coolermaster NR200P or the Raijinteck Ophion or Ophion Evo
4: the case swap will likely be vastly cheaper, but if you really want the smaller case that comes with it the 3060 swap may be more to your liking.

A lot of this has to do with your own personal preferences on these questions.

Good Luck!

Alternatively if you've got another 100 pounds to spend, a step up to either a 6700xt or a 3060Ti could also be options.

Down another path could also be the USED GPU market, which is also beginning to come down from some insanity. If you can find a used GTX 1080Ti, RTX 2070, 2070 Super, or RX 5700XT could be potentially cheaper options depending on the sanity of your Used GPU market.

Assuming that you're looking for a new GPU your main options are the AMD 6600xt and the RTX 3060.

the 6600xt seems to have a bit of a performance advantage over the 3060, BUT either would be a fine piece of machinery. Cost, Looks, availability or Your own personal preference for either AMD or Nvidia could be the primary deciding factor.

If you're looking at Ryzen their 7 series would be a pretty great upgrade, the 3700x was very cheap at the end of it's life($200 ish if I recall correctly) if you can find some old stock New or good condition used that may be a good inexpensive upgrade with a cheap compatable Motherboard and some DDR4.

this would also allow another BIG upgrade via NVME storage for pretty cheap.

I assume your primary usage will be for Gaming? If it's editing or modeling then I'm of less help than usual.

Real world gaming usage, you'll see on average 2080Ti performance across the board with the 3070.

If you have options get the 3070, most of us are just taking what ever is available in our price range.

If you have a specific question regarding a non-gaming setting with specific software that would be best to specify as clearly as possible.

Grats on getting the card, Their PSU fiasco was certainly bad. However unless you have concerns that are beyond simple feelings I wouldn't recommend worrying yourself too much... or at all. You've got a new card from a company with a warranty, I assume you've got your previous card on hand as a backup. Don't worry, enjoy the card, be thankful and if crap hits the fan with a new card then start the RMA process.

oh, and nice PC, grats on having gotten a 3070!

Nvidia recommends 650w as minimum. Calculators seem ok with it. It'll be about the most your psu can handle but it should work. If the PSU doesnt like it it's supposed to trip OCP (over current protection) and shut off. You're likely seeing 750w psu's because IMO they're more common and will cover the greatest majority of HPC enthusiasts needs, Hence the 3080/3080ti/3090 requires a 750w.

That case does appear to be a bit of a hotbox with low airflow so your temps may be more normal for your circumstances.

New case for your next upgrade? Just upgraded to a Meshify 2 compact Light TGlass(which I highly recommend) and my temps with 2x 240 AIO are quite good.

GPU Temps under 80deg C are 100% acceptable and NORMAL. Lower temperatures are always desirable if possible but 80C and under will cause zero problems and no damage and is 100% normal. If the card were over 90-95C efforts to reduce the temps would be functionally worthwhile. The Only benefits from even lower temperatures are greater headroom for GPU boost to clock the Chip higher and for enthusiasts to enjoy/worry about/OCD work to lower(myself included).

Unlike past cards the RTX 3090 is so powerful that it will likely be the pinnacle of GPU processing technology for the foreseeable future(or the next 5 minutes, whichever comes first)

reseat the card

reseat the power cables

insert the card into a different PCIexpress slot

Have you tried both HDMI and Displayport cables?
Are you getting any post codes? (you may need a speaker connected to the front panel headers to retrieve the codes)
Have you tried the card in another known good system?

pretty sure they put me off the list when i returned my unoverclockable 1070ti FTW"2" to amazon...  well i havent heard of them once since... so yeah, also 1 year waiting list, isnt that kinda embarrassing,  especially when there cards are *available* at regular online stores... 

They certainly have contractual product order obligations to retailers that they have to fulfill first, so I don't expect them to abandon those agreements they made in good faith. But, they're the only GPU party to make an effort to help their enthusiast audience. They've not only set up a queue to get you in line, they've purposely prioritized customers who haven't received a card from them yet. So they've made what seem like good faith efforts that no-one else that I've seen has even attempted to make.

After 14 months got my email for the EVGA Queue:

1: EVGA RTX3080 FTW3 (Replacing my Frankenstein Founders 1080Ti with hybrid 240 AIO cooler, now stock cooler)

2: EVGA Hybrid cooler

3: Fractal Design Meshify 2 Compact (my old Meshify C wouldn't fit this card with a front Rad)

So to all the poor souls out there still waiting for the graphics card you would like to purchase... And specifically those waiting in line for a RTX 3080 ftw3 from EVGA.

I inserted myself into EVGA the waiting list on 10/25/20 at 1:50pm EST.

12/14/2021 at 2:01 pm EST I received my email from EVGA and forming me that my time to purchase had arrived.

If you're still in line for that card on EVGAs waiting list, hopefully by comparing when you got on the list to when I got on the list this information could give you some relative idea as to when your spot in line might come up. Hopefully a little bit of encouragement to hang in there.

The op is here for advice on a pc. Maybe he doesn't know what parts are best suited for his needs. It is easy to go on pcpartpicker and select the most expensive part. Anyone can do that. The fact is we should be giving advice on what is best for the op's needs. If he wants to ignore it and buy a 5950X then that is up to him, but I stand by my comment that it is stupid to spend nearly £900 on a cpu if you are just gaming.

 

We don't even know what the op is using the system for, so not sure anyone can suggest a build yet.

 

@IAmJuice What is the pc being used for ? 

Fact is we should be giving the OP advice based upon his needs and wants. Yes he is free to do as he pleases, but calling his decision to go with a 16 core Stupid because it is your opinion is that having a PC that is more powerful than necessary is wrong.

Stand by your comment... but recognize that it is your opinion and nothing else. So it is your Opinion that that choice is "Stupid". The same "stupid" logic the OP is applying here is applied everyday by you and me and billions of others to a multitude of other life decisions and is not called stupid. Next time you buy anything other than a used compact car, a used low end smartphone, a house with any more space than absolutely necessary, a hamburger that costs more than a Mcdonalds cheeseburger, a beer pricier than a keystone light, a pair of shoes other than from walmart,... think about how "stupid" your decision is.

He could also get 128GB Ram, but that doesn't mean he should do it. Spending nearly £900 on a cpu for gaming is just stupid. Of course if he is doing something that can make use of it then that is a different matter. At 1440p there will be no difference between an R5 5600X and R9 5950X in gaming when paired with an RTX 3090. So you are basically paying out an extra £450+ for no gain.

you can also get to work or anywhere you need in a yugo, why anyone would buy something other than a yugo for work is completely stupid.

the fact that he wants something with more power and luxury than he plans to use at the moment is completely normal and perfectly fine. please don't call someone's desire stupid if they have worked hard and have the money and desire to get it, he's willing and able to do this because he wants it.

Go for it dude! you worked hard, it's your money, it's your PC, don't let anyone convince you a 1000$ processor is stupid while most people drive a car and live in a house that has more power and luxury than anyone Needs.

hopefully someone else more intelligent and with more experience than I will chime in with something we're missing... sorry man, i'm out of ideas atm.

i'm not picking up on any immediate easily diagnosed problems here...

My personal next step would be swapping out CPU cooler... maybe there's a problem with the cooler... heat pipes were never filled, mounting surface is defective, ect.

if another cooler performs better, we may have an answer.

Core voltage?

does applying gentle but firm pressure to the top of the cooler while testing offer any reduction in Temps? i'm trying to discern if we have a mounting pressure problem... i experienced this with my h100i several years ago.

also, what kind of core voltage is it using?

Some tests and trials need to be run.

I have to ask, and i'm not trying to offend but keeping it simple is a good place to start: have you removed the clear protective adhesive sticker from the bottom of the cooler?

Looks like this: 

I like that you've tried reseating the cooler, How does the Thermal paste spread look? after removing the cooler, should look something like this. Nice, thin, well distributed, not overflowing.

What voltages is it applying to the CPU?

Have you tried something that isn't prime 95 to stress test? prime 95 small ffts is not always considered a real world test because it is crazy intense and usually much more intense than any use you'll have.

Samsung Odyssey G7 27.0" 2560x1440 240 Hz Monitor

great monitor, response to the need for a 5950X: if the 5950X is what you want, in your budget, and doesn't cause you to give up other more beneficial gaming upgrades because of the price, then go for it.

the fans that came with my meshify c... i would call them above average for included fans, i also have a few HP-12's and IMO they are below noctua but better than average.
