NVIDIA RTX 50 SERIES - Technical/General Discussion

Can't believe people are trying to dodge buyers remorse via telling themselves the price is not too bad because if you look at the bigger picture, the healthcare is better/cheaper overall in the UK than in the USA. ****** hilarious! First post in this thread but certainly not my first bag of popcorn reading it. Carry on, what a read!

And yes I will also be buying one on launch day...

"The thing people don't realize about an ecosystem is that it's a system. A system maintains a certain fluid stability that can be destroyed by a misstep in just one niche." - Frank Herbert

It's important (and more interesting!) to carefully look at all variables and cause and effect when considering buying a computer game toy. These variables can be directly-impactful like price/performance and availability, or indirect like the alignment of Venus to the Moon or Jensen's preferred pot noodle flavour.

5080 + 5700X3D with a 650w power supply? Possible? PC Part Picker is coming up at 651Watts. That's everything at Max though and I've read 5700x3d usually is like 70 watts when gaming.

I don't want to change my PSU but also don't want to wait for 5070 TI or 9070 XT

You might get away with it, I had a 9900K + 3080 10GB on a 650W PSU and they're similar power consumption to your setup. Just don't go overclocking and maybe limit the framerate or something!

Estimated Wattage
AMD Ryzen 7 5700X3D 3 GHz 8-Core Processor 13W - 142W
Thermalright Phantom Spirit SE 66.17 CFM CPU Cooler5W - 10W
Gigabyte GA-AB350-GAMING 3 ATX AM4 Motherboard 17W - 70W
Corsair Vengeance LPX 32 GB (2 x 16 GB) DDR4-3200 CL16 Memory29W
Toshiba DT01ACA300 3 TB 3.5" 7200 RPM Internal Hard Drive 4W - 20W
Samsung 850 Evo 500 GB 2.5" Solid State Drive 2W - 10W
Samsung 980 Pro 2 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive 2W - 10W
Asus PRIME GeForce RTX 5070 Ti 16 GB Video Card 75W - 300W
Total:591W

So even this is a bad idea?

Some of the watt numbers for parts are comedically wrong. That motherboard is never using 70W. Memory ain't using 29W. A HDD is never using 20W.

A 650W PSU will easily be enough.

To give you an idea, I used to run a 5800X3D (142W) and a 7900XTX (355W) absolutely fine on an EVGA 550W PSU.

I even forcibly loaded the CPU and GPU at the same time just to see what the PSU would do as a test for an hour. A 550W PSU was unsurprisingly able to handle the load it was rated for.

I'd recommend in reality a bit more overhead, but it just goes to show how unrealistic people have become because in the past PSU manufacturers would lie about their wattage (when looking at 12v only).

A beefy PSU is THE most future proofing you can ever do with a PC. Go 1300W or go home or man up for 1600W it's all good.

The PSU you have (EVGA 1600W G2) can only deliver it's full wattage through 9 x PCI-E 8 pin power cables. Where do you think you would ever do that outside of mining on numerous GPUs? The biggest adapters I've seen convert 4 x 8 pin (4x150W) to 16 pin (600W).

What I want to know is: why are the 3 fans so small in diameter. Awful awful thermal design. Also worth noting is one of the smaller 5090s in length at around 330mm. Most are 340-360mm.

Smaller fans generally spin faster and should generate more static pressure meaning they should be able to brute force air through the heatsink. Could be noisy though.
 
Bad news, all. Trump has just announced a $500bn investment in AI. No TSMC capacity left for the 6090. Just been informed the 60 series is cancelled. Such a shame. Buy the 5090 whilst you can!

Edit: forgot the /s. Got to be safe these days.
