[SOLVED] Nvidia RTX 30xx / PSU considerations

[Gussv]

Hello to all the tech gurus here 😀

I would like to get into sim racing just like my nephew - however, I'm baffled regarding the recent Nvidia launch and whether I need a PSU upgrade or not.

My system specs:

i7-9700k
z390 Aorus Ultra
64gb Corsair 3200MHz

2 X SX8200 Pro 2tb
1 X Ironwolf Pro 14TB

1 X Asus Essence STX II
1 X PCIe (DVB-S tuner)
1 X USB TV tuner

8 X 15 LEDs
6 X 140mm Fans

Palit 1050 TI silent
Philips 43" 4k 60Hz

Seasonic 650W Titanium

From what I've gathered so far, 3080 is the best buy for 4k gaming, but I'm not certain my PSU can manage. I've used a calculator (https://seasonic.com/wattage-calculator) and it seems, I'm barely making it with the 650w PSU. 🙁

Alternatively, I suppose I could get a 3070 and my PSU with be comfortable with it. But is the 3070 GPU up for 4k gaming? I dunno. 😕

Really need your thoughts on this, peeps.

Cheers

How old is the PSU? Yes I'd get a higher wattage PSU if I were you to maintain headroom.

Thanks. Only a few months old. But, I could get a Seasonic 850W Titanium, I suppose.

If the same thread shows up at the Power Supplies section also, please do remove it.

The 3070 is supposed to have similar power to the 2080 Ti which was good for 4k 60 fps for most high-end games, so
a 3070 might meet with your needs depending on the sim you use. It might be worth researching how your sim of choice played at 4k with a 2080 Ti.

However, a 3080 will give you more headroom for a locked 60 fps and thus would be the better overall option. If you were to get a 3080, you should get a more powerful power supply to match. Yes, a Seasonic 850 watt Titanium model will work excellent.
