Hello

I build new PC and I want your advice. I want to ask Corsair RM850x is enough and good for my gaming computer ? And can you give my some alternative source ? Can you also advise on which components I should replace.

My components:

GPU: AORUS GeForce® GTX 1080 Ti Xtreme Edition 11G
CPU: Intel Core i7-7700K
RAM: Kingston 32GB KIT 2400MHz DDR4 SDRAM CL12 HyperX Predator
Motherboard: ASUS STRIX Z270G GAMING
SSD: Samsung 850 Pro 256 GB
HDD: WD Black 2TB
CPU Fan: NZXT Kraken X62
Case: Be quiet! DARK BASE PRO 900

Thank you.

Here are some thoughts:

For the PSU: Since you got the Asus Z270G (an mATX-sized motherboard) and the Gigabyte Aorus GTX 1080 Ti Xtreme, you won't be able to SLI anyway as the GPU occupies 2.5 slots while the mATX mobo's 2x PCIe x16 slots are only spaced 2 slots (i.e., the GPU will overlap over that 2nd PCIe x16 slot). This leads you to select a PSU of ample wattage only (eliminating the need for a 850W which is meant for an SLI setup since you can't do that anyway). A good-quality ~550W PSU should be enough (with a ~650W PSU offering better headroom/efficiency when OC'ing). The Corsair RMx series are very good quality PSUs, so, just get the RM550x or RM650x versions to save on costs.

For the case: The case you also...

get the 650w model, 850w is grossly overkill

Even with a high OC, the RMx 650w is plenty for a 1080ti. The only bonus to the 850w model would be if it was the same price as the 650w, if not, then no point in spending extra cash for power that'll never get used. Ever. Unless you plan on sli, in which case the 850w will be perfect for the job.

If you aren't going to do a lot of rendering or other high ram usage app, even 16Gb can be considered more than enough. You are hard pressed to get any app to use more than @12Gb of system ram. 32Gb is way more expense than warranted for a gaming pc.

Rest looks good.

For the case: The case you also selected is a huge full tower case. With an mATX motherboard and an AIO cooler, you'd have a hard time filling up the "void"/blank spaces inside. Consider selecting a much smaller case, to both save on costs and increase aesthetic appeal.

For the RAM: The 32GB kit is overkill, and you won't be able to use more than half of that this gaming PC. 16GB (2 x 8GB) is the recommended/sweet spot for RAM in this day (and will probably continue for years to come). Consider getting a faster RAM speed of ~3000MHz and up (instead of the 2400MHz) as your motherboard and CPU are meant to be overclocked.

For the SSD: The SSD will have no significant performance increase during gameplay compared to an HDD. What the SSD dramatically offers is very fast loading times (esp. in open-world games) and boot times (OS startup). Consider getting the 250GB EVO version instead of the 256GB PRO for better price/performance.
