8700K & Zotac 1080 Ti - boosted performance
Hi Guys,
I haven’t really needed to check power supplies before since I’ve never used a high-end rig. Here are my current specs:
Gigabyte Gamer 5 Z370
Intel 8700K - 5.0ghz
Cooler Master - Master Air (2x140mm)
Zotac Amp Extreme 1080 TI 2027mhz
Memory 3200mhz
1x M.2 drive
2x SSD drive
3x 120 fans
2x 140 fan
My power supply is a Cooler Master -650W RS650-AMAAB1-UK G650M.
The computer runs and games work fine, but I sometimes notice odd behavior like FPS drops or crashes. I’m not sure if it’s related to the power supply, but I think it might be. Could you confirm? Thanks!

Check the tier list first before making any purchase.
Visit the provided link to review the PSU tiers.
Generally, buying a higher tier is better, regardless of efficiency grade—bronze, gold, or silver works fine. (I believe there should be a bronze PSU in the Tier 1 range)
The PSU itself is quite good, especially if it appears on the Tier 1 list.
If budget concerns arise, consider Tier 2, but avoid going below Tier 2 for reliability.
650W should allow some headroom for overclocking on both the CPU and GPU. The motherboard's power supply is decent, though not top-tier. The amount of space available isn't clear. If you experience frequent crashes, consider trying an OC first before changing settings. Let everything operate with default configurations. Persistent crashes suggest the OC might be unstable. Game crashes aren't always your fault—they could just be a glitch. FPS drops? Have you switched to performance mode instead of power-saving? Check via NVIDIA control panels and Windows energy settings. FPS reductions can also stem from poorly optimized games.
Thanks for the response, Guanyu. That's a concern about the powersupply... I'm someone who notices when something isn't working properly—it really bothers me. I just tend to spend my time elsewhere. I bought the card a few days ago and was testing Rise of the Tomb Raider on my 4K TV. It wasn't performing well at high resolutions, which is why I mentioned this because I've seen similar cards with lower-end parts achieving better frame rates. On mine, it feels much slower.
I've been in the computer industry for about 15 years and have checked all the basic settings, like the power on NVIDIA options. Maybe I was expecting more from the Ti and thought something was not up to par.
4k? hmmm....some frame drops should be normal here. 4k is not yet the best thing for gaming, GTX1080Ti is considered as minimum, yet, it is already at the top.
I dunno about 4k for Tomb Raider tho'.
The crashes should take more of your attention.
About the PSU,
According to my rough calculation, your PC should need about 550-600W on full load. This leaves only about around max 100W for spare room e.g. for OC.
It depends on how high your OC is and how the power consumption from the OC is...perhaps it is tight or not enough...
Yes, there is also a possibility that your PSU is not enough.
The thing..is..again...you just simply have to turn off the OC.
I think you probably already know this.
You might wanna monitor the temps on proc and gpu too.
I completely understand about the crashes; I think the main issue is more about FPS drops across several games instead of crashes (though those still occur).
Your calculation seems to consider these GPU settings—power limit at 100% and core voltage at its maximum.
Check the link below for my GPU overclock details—maybe it's not the overclocking I'm doing correctly... I wouldn't expect bottlenecks.
Also, this could assist with some of the other settings I haven't mentioned.
Thanks for your time, Guan
GTX1080Ti is not running on 2027mhz by default. The Oc is quite high there.
btw, that Zotac is factory OCed.
It should consumes more power than normal GTX1080Ti, which I used for rough estimation.
The card consumes even more, especially if you OCed it yourself higher.
There is no wrong OC, since every graphic chip is unique. Some can go high and stable some can not....same for cpu, as always...
ah...your 3dmark score is quite good...but if it is not stable, it is useless.
Yea sorry, idle its roughly 1607 then kicks up to 2020 when on load same with the memory at 6100.
I did just use a power supply calculator but got stumped at the "overvoltage" part on the calculator is that meaning the core voltage on msi afterburner? if so that is at like 100% along with powerlimit ... and the PSU calculator said i am using about 900+watts? this is a new area too me so tell me shut up whenever lol.

thanks

650W bro i suggest going for 750w EVGA G2 if you're doing an overclock
that is poor PSU for that system overclocked you need tier 1 at least tier 2 PSU with more power so go for the EVGA 750 G2 definitely
