How much should i worry about the RTX 3000 power spikes?

[Lord Szechenyi]

I recently saw the 3090 SLI video from ltt, and Linus mentioned how regularly there are power "spikes" from the cards.

now after using https://outervision.com/power-supply-calculator. an i9-10900 + rtx 3070 (+ a few fans and RAM) puts me at around 500W, and i have a 550W 80+ Bronze psu, will i be fine or not?

outervision is not particularly accurate and shouldn't be trusted.

not a very good power supply for your uses, an i9-10900 can draw over 200 watts with a 3070 also being about 220. it does spike in power so if you were using a 550 watt PSU you'd want it to be a high quality unit. Have a look at the PSU tier list to get started, and if high core count CPUs with powerful GPUs are what you strive for, maybe a 650 watt or 750 watt PSU are ideal to get a decent upgrade path.

TDP is thermal, not power

An i7-7700, with only 4 cores, is a 95 watt TPD CPU

ooooooooooh ok i understand now, thanks.

How accurate is this?

there really aren't any accurate PSU calculators, they basically all use TDP to try to estimate power usage. You'll find that if you go to websites where measurements for component power draw and add them together yourself, you'll get very different results.

 

Tomshhardware is usually one of the best references for component power draw, with a lot of comprehensive analysis

i was unable to find one for the i9-10900, only for the K version, but i'm not interested in that one, only the base one.

can you help me find something reliable?

Non-K version should consume much less than 200w.

this techpowerup article seems to have a good amount of charts

max turbo without a BCLK overclock has it at 243 watts. Mind you, that is "whole system" power draw but they're running a CPU only benchmark and the additional watts would be negligible (handful of watts for ram, motherboard, SSD) so the wattage for the CPU itself would still be pretty high, in the 200 watt range.

why should it? 10 cores, 14nm inefficient power draw, the 9900K draws like 180 watts at stock

i probably won't turbo the cpu, but again this is Cinebench.

i only need the cpu for 2 or 3 games. not rendering

it's a lot better to plan for what the CPU can do, not what it might usually be doing.

 

also, disabling turbo boost? do you know how low the base clock on that CPU is? what a waste. If you're gaming, get a 6 core CPU and let it turbo, cause it'll outperform a kneecapped 10 core CPU 10 times out of 10.

well i'm not going to turbo, so should i get another 10th gen intel cpu?

maybe you can help me on that.

currently i have the i3-10100, and i'd like a cpu that won't bottleneck the Gpu (probably the rtx 3070) in the following games:

Hitman 3

Star Citizen

[-iSynthesis]

That's like a 500$ CPU + 500$ GPU, just please don't try to save extra bucks on something as important as the PSU. You have the money if you've spent that kind of money already

i5-10600 or 10600K offers top tier gaming experience at a fraction of the cost of an i9. Gives you the spare funds to upgrade the PSU to a higher quality unit.

i don't actually.

i'm going to sell my 1070, which easily goes for 250$, and that way i'll have enough for the 3070.

then i'll sell my i3-10100 for 100$ and get the i9-10900 around december january

Damn.  
But that was an AVX load though, for gaming it won't get anywhere near that.

I guess? but having hardware sitting on a PSU that can't handle it at load is bad practice

 

if you can't handle me at my worst you don't deserve me at my best

that might be a good choice.

but i also want to mention that, i'm planning on reselling my computer before the end of 2021, and i want to know how much will i lose choosing an i5 instead of the i9 (as in, the price difference from when i bought it and when i am reselling it with the complete pc)

you're spending less money and you're making less money, it'll be pretty proportional and you're not really "losing" here.

 

also a lot of people are gonna pass with an inadequate PSU in the rig so that should be priority one. If you want it to be more "gamery" you can toss an i7 in there, still more appropriate even if 8 cores 16 threads is overkill.

Depending on how good the 5600x is, you might want to consider going with it. What motherboard do you have?
