Is my 750W-Seasonic Tx enough for Rtx 3090 without OC?

[das3erawsdas]

Hello. I ordered Palit Gaming Pro Rtx 3090. My psu is: Seasonic 750-TX PRIME ULTRA TITANIUM.

https://proline.pl/zasilacz-seasonic-prime-tx-750-80plus-titanium-750w-p1403120



It will be ok?


cpu is 9700K,32 gb ram,1 sdd,1hdd

Somebody on G3d forum said:"So I have this issue with my 3090 FE and it's when I play with power limit and set it to 114% my card power peaks around 390-395W of power but after playing a game at that power limit my pc will just shut down. Do you think I am hitting my psu power limit and it just shuts down? I am on Seasonic Prime TX-850 Titanium (not even a year old). It's only when I play with power limit

Here's one game where it will play for a bit and just randomly shut off my pc. Temps are good all around so the only thing I can think of is 850W is not enough power for this card."

So without oc and raising power limit i will be not have shutdowns like him?
Also he is using 1x12 pin adapter because its FE card.
My card will be have standard 2x8 pin. + i dont mind to overclock.


So should be fine?

Problem is these cards dont peak 400w. These card peak way higher then this. They showed this in many test. Its only for a few ms but it could be long enough to make your psu shut down. Hw monitor doesnt show this corectly of you look for power draw.

If i remember corectly igorslab showed 450w for few ms on non oced 3080FE. 3090 should be much higher.

750w is not enough. You need at least 850w or more to ensure system stability, especially overclocking.

[das3erawsdas]

Many peoples using 750W with that cards and they told its fine.

[Kobs]

It has good reviews everywhere, fully modular which is what I look for in a PSU and 750 is on the high end future proof wise

[Monk]

I'd keep it, try it out, worse case it shuts down under very heavy load and you then buy a new psu.

I am still waiting on my 3090, but under normal use I don't see it actually using more than 750w.

Since it's a Tier 1 PSU with 80 PLUS Titanium power effectiveness, it might actually be fine.

Your PSU has a +12 Volt rail with 62 Amps and max 744 Wattage towards it. So it's isolation just a little part of the wattage for smaller components such as the motherboard, which will be enough for it to still boot. If you have random booting problems or a black screen sometimes, when first starting up, you will know it's a shortage on the PSU end.

You won't get to the point of crashing out during gaming, loading the operating system, etc.

It will depend what brand/model of RTX 3090, but one without overclocking should have no issues. The flagship founders model of the RTX 3090 has a 350 wattage pull. It would be the overclocked and custom triple fan setups which would use more.

Factor in your monitor usage, motherboard, cpu (AMD tends to use more juice than Intel), solid state and hard drives, and the other components usage for a total wattage ideal, then make sure when everything upon that is maxing out, it's still has some room to flex below the 80 PLUS rating of efficiency.

You have the highest, 80+ Titanium. 96% efficiency at 50% load and 90% efficiency at 100% load. So try just keep that running at a max load of 90% for 100% stability. It then had 10% more headroom to flex, but could become randomly sometimes unstable then or just waste power, while increasing it's fan noise and heat usage.

Will a platinum rated corsair 750w be enough for all the variants of the 3080 with a high end cpu like 10700k?

Yes as test ive seen say they pull around 320w tdp to 360w tested (without OC), will be ok. Need 3 8 pin powers tho.

This is a lot easiler to calculate with all the specs.

You need to know motherboard + cpu, ram, graphics card brand/model, monitor, drives, etc. There's a power draw from each component in your PC, but the graphic card takes the most.

The Intel 10700k can draw up to 300 watts, even if overclocked.

Then the standard RTX 3080 draws additional 320 watts.

So that's 620 watts, plus some smaller components with more draw.

Add another 20-40 watts for an LCD monitor (depending on it's resolution and screen size).

Your motherboard probably uses 50 to 150 watts (depending on brand/model/series), and each stick of memory requires about 15 watts.

A drive draws wattage slowly over time, so it's probably 2 watts each. 5 drives could be 10 watts.

Do you also have a DVD player or anything else?

Now it might be getting up to 770 watts at max load times, which is where it becomes risky and unstable, if that's the case. Or it just refuses to boot correctly at random times, because a device will drain the power from another and prevent it from starting. Newer and higher-end PSUs will however isolate these rails, specially low power from high power, and again with the PCI-e power connectors (going to the graphics card). So you won't get that drop out as bad like you use to in the past.

The other thing is the amps over those rails. Some PSUs will offer much higher amp ratings, while cheaper ones will tend to share both wattage and amps between the rails (meaning one could drain the other easier).

It's why I dropped this URL to help out:

You can use the "BASIC" version, unless you have a complex build with a water cooling pump, etc.

I'm not to much of an expert with pc building, do any psu come with 3 8pin power connectors? Im looking at my pc build and its one connector that splits from one cable into 2 8pin

Sounds like 850w should be the minimum, I dont have a optical drive and will be using an AIO cooler system with standard amount of case fans. Other than XMP and if the 3080 bought is already an OC card, i wont be overclocking. Do you think I should sell my brand new 750 corsair for an 850 one?

Every good modular psu will come with multible 8 pin and in most cases way more then 3. You are right about 850w for safty. I have an i9-9900k which is basically the same cpu and while playing games i peak 700w. This is not max load if cpu and gpu get used at same time.

It is borderline, you maybe able to get away with it

If it's brand new with a receipt, can you return it?

Just claim the PC doesn't boot sometimes and ends up with a blank monitor. Then you saw that the graphic cards used in it recommends 850W or higher. So is it possible to replace it with a higher watt model.

They should happily trade you with an up sale. You then just pay a little extra for the difference. The company should be fine with it too, specially if it's the same brand PSU. Everything is still there, box, manual, bags, cables and all.

A bit annoying removing all the cables out, so ask a head of time on the phone or website contact us.

I know for the Nvidia GeForce RTX 3090 PSU requirements, you'll want a 750W power supply if you pair the card with a mainstream Core i5/i7 processor or Ryzen 5/7 CPU. That requirement jumps to 850W for Intel Core i9 and Ryzen i9 chips, with a peak of 1000W for Intel HEDT and AMD Threadripper platforms. The RTX 3080 should be similar or less than that.

The Intel 10700k CPU is a 10th Gen, but i7 right? So the 750W should still work. If it's not that easy to replace, I wouldn't worry about it to much. Just stress test it a bit and ensure it remains stable.

Strong and efficient 70A power stages on the main rails ensure the cleanest and most reliable power delivery. So check the +12V rail of your PSU and check is that 70 amps and higher? If so, then your 750W should be okay, thanks to it being a high-end one. It should also have 3 or more PCI-e power connectors, if it doesn't have that, you will need to replace it.

i have a very similar system to you (i7 8700k, 32gb of ram and 3 ssd's) i highly suggest you get a 850 watt psu for the 3090 as i just upgraded to it and with its power draw spikes i can somewhat barely get away with an 850 watt gold psu

You will get away with it if you undervolt (which will make you lose no performance if you won the silicon lottery). You can shave off 50 to 100W power consumption that way.
