Build Compatibility Help

I have been looking to upgrade from a laptop with a GTX 1060, I have been going through multiple different builds only to recently realize that I need to check the compatibility of Power connectors and clearances, etc. Now that I have taken that into account as a noob to the building I got overwhelmed very quickly at all the different properties of certain parts.
Heres what I have so far:
NZXT H710 (CA-H710B-W1)
AMD Ryzen 7 5800X
MSi X470 Gaming Plus MAX
KLEVV BOL:T 32gb DDR4 3200Mhz
H150i RGB PRO XT liquid CPU cooler
Gigabyte Geforce RTX 3080 GAMING OC LHR Edition 10G
SabrentRocket 1TB NVMe SSD
Antec VP 700Wp

please help with some advice on how to pick compatible parts (PCpartpicker is useless) and if these parts are compatible.
Thanks in advance
 
Go for a motherboard with B550 or X570 chipset.
 
Grab a case with better airflow like a Phanteks P500A.
 
Your power supply is less than the 750W recommended by Gigabyte for the RTX 3080:


Personally, I would be more inclined to put an 800W or 850W PSU in this build.
Alright thank you, I thought I might be able to get away with 700 since I assumed 750 was recommended

PSUs are more efficient when they are NOT pushed to their limits. There is nothing new about this, it has been this way for decades.

Countless system building guides/tutorials have admonished not to cheap out on the PSU and you blatantly ignored this.

For your power supply, round up, not down.
 
Your system will average out at 350W of consumption for the vast majority of usage cases anyways. You really do not need a 1,000W one, but you do need at least a known good 750W because otherwise transients may trip some protection features and shutdown your system.

Average might not be the right thing to go by here. RTX 3080 has a 320W power limit which it will hit unless something is done to limit the GPU usage (for example low resolution or vsync). 5800X has power limit at 142W. It will not likely hit quite that at gaming but some games that have higher CPU usage will get it past 100W. That is 420W from only these two components. What the rest of the computer uses under load depends on motherboard, peripherals etc but a sustained consumption for this type of computer is likely ~500W. With the current generation of thirsty GPUs there is also the transient spikes well past the limit at 40% or so (for RTX 3080 those were measured at almost 500W for <1ms) that may become a problem depending on specific PSU.

Long story short - for a computer like this I would definitely go for a PSU closer to 1000W just to be on a safe side.
 
Yeah my 3080Ti and 5800X in warzone sit around 550w I wouldn't expect a 3080 to be much lower.... I personally wouldn't pair a 3080 or above with anything less than a quality 850w unit min.


With my 5950X pbo enabled and 3080 ti power limits maxed it can hit 600w at the wall anyways.

Titanium rated psu

I tried using a corsair RM750 2018 model with it out of curiousity but it trips ocp on it. Handles a 2080 ti strix no problem. Haven't had a chance to test it with a Seasonic GX750 yet.

I assume that your card isn't undervolted

No I typically run all my cards stock out of the box but do some testings with power limits maxed out. Undervolting is technically overclocking and while I recommend people at least try to do it ymmv and you could end up with a card that doesn't run well undervolted.... Also it really isn't the actual average power usage that is the problem with upper end 3000 series it's the transient spikes for a couple ms into the 500w range I'm not sure how much undervolting will help with that. My 3080 ti actually only averages about 40w more than my 2080 ti but my guess is the transient spikes are substantially higher.
I'm sure a better quality unit than my RM750 psu would likely be fine.

The cost difference between a quality 750w and an 850w is usually 20-30usd no reason to skimp on a build that will likely cost 2k+

My 3080 + 10700K in CW power usage is 350w/53w, just the 3080 undervolted to 0.862v 1890MHz uses no more than 200w.
i Know that my MaxTytan 1250W 80+Titan is way too much for my System but i don't mind prices when buying a PSU.

My main system only averages around 400-450w in Warzone less in CW but it does have brief large spikes into the 550-650 range. Both quite a bit under 750w but it still triggers ocp on the RM psu. You definitely have what I would call an overkill psu but that's better than having a psu that barely cuts it

MSi X470 Gaming Plus MAX
Replace that with a MSi B550 Tomahack
KLEVV BOL:T 32gb DDR4 3200Mhz
Replace that with a 3600MHz kit, ( dual channel for guaranteed stability )
SabrentRocket 1TB NVMe SSD
Make sure its a PCIe 4 drive
Antec VP 700Wp
Replace that with a 850w GOLD PSU, something like a Seasonic GX 850, Corsair RMx 850 (2021), Phanteks AMP 850, NZXT C 850, EVGA G3 850 ( dont buy the G5! ), MSI A850GF,
Thermaltake Toughpower GF1 850, Fractal Design ION+ Platinum 860w.

All the power supplies i listed above are top performance unites for a good price, pick whichever is cheaper where you live and you'll chug along fine

I've joined TPU 7 years ago and in those years i have seen people recommending all types of power supplies except Enermax :shadedshu:
 
That is your current psu, study the max 12V output (Watts) and your Rails (Amps)

Go here for psu reviews.


 
nzxt over phanteks anyday, lol...:kookoo:

While they do have excellent build quality airflow performance is abysmal.

Much better off with something like the Corsair 5000D if you want a square white/black box.

Otherwise might need high static pressure fans up front lol

Yeah, some of those new Phantek fans would probably fix the problem.....


But spending more on fans than what the case cost to get good airflow is kinda dumb lol.
