Can my Seasonic Prime Titanium 650 handle my futur RTX3080?

[tachikoma01]

Hello,

I managed to order an MSI Geforce RTX3080 Suprim X but I'm starting to have doubts if my PSU, a Seasonic Prime Titanium 650 will be able handle it.

My configuration is a  i7-8700K@4,6Ghz with 1.29v

2x8 sticks of RAM

2 Nvme + 2.5" SSD

4 fans total (including the one on my Noctua NH-D15)

No RGB

Other than that only small things like USB for xbox controller and 1usb bluetooth controller for my logitech K400 keyboard.

I'm thinking it's a Seasonic, it shows 648 watts for the 12V, it's a Titanium so of course it will be ok. Then after I managed to order I saw it's probably one of the RTX3080 that draws the more power, I saw somewhere, it can climb to 400 watts. So I'm lost...

I plan on using the quiet mode.

Anyone with a similar configuration can confirm my PSU will be ok?

 

PS : I have a HTC Vive VR headset but I don't think it draws power from the computer PSU.

no it wont. effiencu is not quality.

To answer your question you should get better psu since 3080 has high power and transient spikes.

I've had a RMx 650W running with a 3700X / 3080 combo. It really was running at it's limit, which i noticed because it was loud af. (Both coil whine and the fan)

I switched it out to a RMx 850W and my noise problems were gone. That being said other than noise, i did not have any stability issues with the 650W PSU, but the RMx are very good PSUs to begin with and set the bar very high.

Yeah but it's at minimum 200 euros more and a lot of 850 watts PSU are out of stock, so if there is no stability issue, I rather stay with my current PSU.

There is a good chance that the GPU will trip over current protection of your PSU and cause the system to shut off. But since you dont have that powerhungry of a cpu you could try and upgrade the PSU incase there is instability.

given Prime PSUs are one of the few units that are transient sensetive, its entirely possible that the unit will trip. in fact is pretty likely unless Seasonic changed something, and its a very new batch

It's definitely not a new batch, I bought it in December 2017.

Thats exactly the year when they had the problems. Contact them and see if you at least get the new cables for gpu. I dont know if you can call it faulty for tripping when a gpu draws 800W:s but with those prices you should be able to trust the psu to out-perform models priced -50%.

yeah thats far too old for focus gx changes to have made it into Prime units. and afaik we dont know if they actually made any changes at all.

yeah its a byproduct of the horrid boosting algorithms used for the high TBP GPUs this year. we saw this with Vega and the pre-fix focus fx units (pre-January 2018) to a lesser extent. Ampere is just much worse.

Minimum would be a 750w.

So, a little follow up for people wondering, it's been 2 weeks now since I've received the card and so far I have no problem.

I have not tried intense work load like OCCT PSU test or furmark + blender. But in games, like Red Dead Redemption 2, Resident Evil 3, Yakuza like a dragon and Dragon quest XI, I have no problem at all so I'm thinking I won't even replace my PSU unless problem starts appearing.
