Question RTX 4000/RX 7000 price speculation thread

[moonbogg]

My prediction: The entire generation will be 2-3X msrp on ebay and at retailers. RTX 3000 series will be sold along side the 4000 series because only a few will be buying RTX 4000 series who are willing to pay $1500 for what should be a $300 RTX 4060. Not enough supply to meet demand by a long shot, pricing will be through the Oort cloud. PC gaming is dead. Your thoughts?

- And here I am on my 6600K, rounding out 6 years of service come June...

Going through some old photos and I guess I took a picture back when I got my GTX 1080 in 2016.

I was expecting a picture of a crib with you in it and a 1080.

You got the 850W version of my power supply...

I should really upgrade that PSU soon.

 

[Aapje]

I would hold off on upgrading PSU's if possible, until the PCIe 5 ones arrive.

Wow, rocking a Zalman CPU cooler, eh? I haven't seen one of those in ages, although I thought it was the shiznit back in the day.

What are the odds were going to need to upgrade? I have a corsair ax860 so I'm hoping itll hold up to 7800/4080 but not sure...

Yup, but I had to purchase a Socket 1366 bracket to mount it.

Still using the power supply for my current PC and the RAM is being used in an i9 9900k system. The Sandisk SSDs found new life in my son's PC as well.

That's up to 10 years old, but Corsair rates their power supplies as having a MBTF of 100,000 hours, which is 11 years of continuous running. So the odds are quite good that it will last another 6-12 months.

Failures tend to be high early and late in the life of a product, so once you've survived that early period, you can expect an average MTBF that is longer than the rated MTBF.

Bought this back in 2016 and it obviously hasnt run 24/7, but toying with the idea of replacing it.

This one's inexpensive and got good reviews.

Friends don't let friends buy "Apevia" PSUs...

They used to have a bad reputation. They are trying their best to fix it now. Their current models are not horrible. Or maybe you have some recent horror story?

There are no in depth reviews I can find. Amazon user reviews are completely worthless.

Corsair, Seasonic and Silverstone sell very good units. Sometimes, you get what you pay for.

 

[GodisanAtheist]

My worry with my HX650 unit is given modern cards tend to have really bad load spikes, combined with the age of the unit as well as its relatively "low" power rating, is that I'll finally get my hands on a reasonably priced GPU that ends up drawing too much power for my relic of a PSU and everything burns out.

 

[igor_kavinski]

To be on the safe side, I wouldn't pair anything more than a 3060 12GB or a 6700 XT with a 650W PSU and that's with a 65W CPU.

A 3070 is max 250w even overclocked. You could pair that with most CPUs on the market and still have 100-200w headroom. Any AMD CPU will pull 140w max, as that's the limit of the socket.

It's the transient spikes that are worrisome.

I think thats similar to an issue i had, my previous setup (i7-6700k) with same gpu (5700xt) and PSU would hard crash about a year after i bought the gpu. Id be gaming and everything would instantly just go dark. The stock cooler on the gpu wasnt up to snuff, was consistently hitting the 110 deg C thermal limit for junction temp and it would throttle. Undervolting the GPU and installing an accelero fixed it for the most part.

With new setup (5800x with 32Gb RAM, same everything else) i dont seem to have any of those issues...throttles occasionally but not nearly as often, typically runs in mid 80s-90s. Wonder if power spikes at higher temps couldve contributed?

How do these 2 posts begin to be compatible.

3070 NOT 3060 = say 400 W max with transients.
65 W CPU = say 100 W

PSU = 650 W

I'm not comfortable running a PSU close to its limits. 650W at 80% efficiency is around 520W. I got my $300 Z77 mobo's PCIe lanes (all of them) fried because I was dumb enough to run an RX 580 on it with a 400W PSU. Never again.

You have the efficiency wrong.

A 650 W PSU of 80 % efficiency outputs 650 W and draws (650/0.8) W or 812 Watts.

Wow. Thanks! Serves me right for trusting what a shopkeeper told me.

 

[Golgatha]

Wow. Thanks! Serves me right for trusting what a shopkeeper told me.

It's actually an efficiency curve, with minimum efficiency being at the low end (less than 20% power). Anywhere between 20-100%, you'll have better than 80%+ efficiency, with the maximum efficiency being around 50% of maximum power. As maddie said, the power drawn at the wall is power delivered divided by the efficiency percentage as a decimal.

e.g. 1176.5w (1000w/0.85) at the wall for a system using 1000w of DC power for the 1000w power supply going by the chart below.
