PSU Wattage and reccomendations

[Entropy.]

Hello- I have been planning to do a 3950x and 2080ti watercooled excessive RGB build... Somewhat like linus's Ultimate watercooled RGB build, and I'm unsure what PSU and wattage I should get for it, because I Don't have any previous experience with anything like this. My main componets will be listed below:

 

-3950x

-2080ti

-360mm rad x2, (6 120mm rgb fans)

-MSI MEG ACE X570

- Lian Li pc o11 dynamnic 

- Lian Li pc o11 RGB side and front Distro plate with integrated pwm pumps

-Trident Z NEO 8*4 3600 mhz RAM 

-RGB watercooling fittings

-RGB waterblocks for 3950x and 2080ti

 

Any advice for a good PSU? I've been eyeing the ROG THOR 1200W, but do I need it? Or could I go 850W? Please don't point me towards the teir list, I've already checked it out, and I found it helpful but I still am looking for people that can give me advice based on my circumstances

You're talking about what, a 140W CPU and a 280W GPU. Even if we add 50% for OC and 50W for the rest of the system, you wouldn't even be drawing 700W. So basically a 750W power supply would be fine.

RGB Bling my man. And excessive fans/cooling

more RGB and Fans wont consume that much power

6 fans, 2 pwm pumps, ~150 indivudal rgb lights.  Maybe not a ton (of power draw), but I'd think a bit over 50W, perhaps with 2 nvme's and a sata ssd It's more than 50W, maybe with all the IO I'm going to use for my peripherals tops 50W. Maybe I'm wrong

Asus ROG Thor PSUs are very solid power supplies - they are just ridiculously overpriced. And you won't even be able to see it in your O11-Dynamic. I agree with other commenters, go with a 750W PSU, that'll be plenty. If you need to get rid of your money and you just want a beefier one, then go with 850W, but everything beyond that is just.. unnecessary to put it mildly.

NVME <1Watt

SSD   ~1Watt
Fans ~2Watts
PWM pump up to 25Watts (usualy at startup)
150 RGB leds ~10 Watt

It might, but not by that much.
Specialy since most numbers are from MAX power draw and most dont even reach that max most of the time.

And there are more then just 750Watt PSU's in Tier A+

Thanks. I'm thinking the HX 850 platnium now... 

One of the Main selling points on the PSU was the OLED screen, and yes, I know I won't be able to see the rest of the PSU, but still the OLED screen. I'm here somewaht for functionality, and beauty

My 2080 ti with only a 5.1ghz 6 core CPU can use close to 600 watts in a game or app that uses all the CPU and GPU. That is with my benching setup. With my 24/7 overclock it is at 550 watts on a game like AC:O.

 

My EVGA FTW3 Ultra 2080 ti uses 387 watts max overclocked. The 6 core at 5.1ghz uses about 150 watts. I don't have RGB but I think the VRMs.

On a game like AC:O it is a 550 watts most of the time.

 

With the 860 watt PSU I have on that rig I feel very limited since I can not put another 2080 ti in it even though I own one. With my 1000 watt PSU in my other rig that is doable.

 

If I was building a rig with your specs I would use a 1200 watt PSU.

How are you measuring those wattages?

My GPU wattage through Precision X1 and GPU Z. CPU wattage is through HWiNFO64. From the wall I use a cheap Power Meter Plug from Amazon.

 

If you know a better way that does not cost a lot please let me know.

Software readings are generally inaccurate, and measuring from the wall gives you the AC input power rather than the DC output power. The latter is what PSUs are rated by, and it's always less than the AC input power.

Saying it is inaccurate is pointless since everything that measures is inaccurate. It all depends on how much.

 

 If you have a better more accurate way please let me know.

The point is your numbers are likely overestimates.

Yes, but I can only use the tools I have until someone shows me a better way.

 

In the meantime I will overestimate since it is alway better to have more than you need than not enough.

The difference in price is not worth the headaches if I get it wrong.

With the Lian Li O11 Dynamic the PSU is mounted in the rear compartment so as you mentioned you won't be able to see the OLED screen on the Asus PSU. Aside from the OLED screen it's basically just a Seasonic Prime Platinum underneath, which is about $30 cheaper than the Asus Thor. May as well save the money and buy the Prime instead since you can't see the screen.

If you are interested in monitoring your systems power usage the HXi series includes Corsair's link feature which allows you to monitor the power usage in software with Corsair's iCue program. All of the i series PSUs from Corsair (RMi, HXi, AXi) include the software monitoring of power usage. Price wise the HXi should be roughly about the same as the Asus units. If you don't care about the power monitoring then the HX is a little cheaper than the HXi.

There's a cutout for the PSU, I will be able to see the oled screen :d. I'm also interested in veiwing it in hardware, insted of through a software that I'd literally only use for that purpose (I'm doing a razer chroma build)

I can understand not wanting to add any more bloat to the system, all the RGB apps and stuff get a bit much. The iCue app is the same that's used for all of Corsairs stuff so if you had any fans, mice, keyboards, headsets, etc from them it'd be all in the one app.

 

You're using the Lian Li o11 Dynamic, correct? Once the side panel is closed you won't be able to see the screen on the PSU.

I've highlighted roughly the size and location of the OLED screen for the Asus Thor units (the numbers on the screen will be upside down when viewed from the side with the side panel off btw). The only way you'd see it is if you leave the side panel off or if you remove the HDD cage, remove the rear panel that covers the HDD/2nd PSU bracket, and turn your PC around to look at it through the back.

Unless you have a custom side panel with a cut out for the PSU or there's something else that I'm missing?

Oh wait. . . I'm so stupid. I thought the power output and the OLED screen were on the same surface. Sorry Bout' that.  Unfourtunatley for Corsair, I'm a huge Razer fanboy, for just about everything, so no dice there

There is the Enermax MaxTytan which has a display on the back of the PSU which shows its power use, but that's quite a bit more expensive than the units you were looking at and not as fancy looking as the Asus Thor.

Aside from the "Oh, that's interesting..." factor it's not really that important knowing how much power the system is using. You can just buy a wall meter for $10 that will tell you how much it's drawing from the mains and they will track your total power draw and average usage and some of them you can put in the price you pay for electricity and it will track how much it's costing you and all that sort of stuff. Practically speaking that's probably more useful, and it's cheaper.

 

So if you don't care about monitoring the power usage that opens up a whole bunch of possibilities for power supplies. Corsair HX/HXi, Be Quiet Straight Power Platinum/Dark Power Pro, Seasonic Prime Platinum, EVGA P2...

You can still just use the Asus Thor but you just won't be able to see the OLED screen, though as mentioned earlier you may as well just buy the Seasonic Prime Platinum and save the $30-$50 difference. Same with the Corsair HXi you can still use it just as a normal power supply without the Corsair iCue/Link functionality, just don't plug in the USB cable or install the software. Though you may as well save the money and buy the cheaper HX instead.

My system is similar to yours in a lot of ways, including the 2080 Ti, and I highly recommend the Corsair RM850x. It’s 80+ Gold, fully modular which is a godsend for cable management and, even though it’s a bit more power than necessary, it’s nice to have a little bit of wiggle room.
