Bringing my PC to the modern era

Hello @myLord95 and thanks for posting on the Microcenter Community Forum. First thing we see is you have a AM4 CPU cooler and a Intel CPU. That Noctua won't fit on the I5-11600K processor.

Try going with a Cooler Master Hyper 212 Universal cooler sku# 864199.

We're assuming you are wanting to use your old HDD to boot to windows with the new build pc. You may have some issues with that.

There are ways to get your new build pc to boot from the HDD (ex., Legacy/UEFI mode), but those steps do not work all the time and PC builders have to re-install Windows sometimes.

We recommend to purchase a copy of Windows, just in-case your new build won't allow windows to boot from the Hard Drive. If it boots, then you can always return Windows 10 if you like.

Now lets answer your questions.

Question #1: 600w PSU should be enough.

Question #2: Looking at the requirements for Star Citizen, the integrated graphic isn't enough for this game. Go with a entry level GPU like the Radeon RX 580 or a GTX 1080 GPU. The  i5-3570k has 4 cores for processing. The I5-11600K has 6 cores, so you're only going up 2 cores. Star Citizen and normal usage of the game doesn't look to require a 6 core processor. But the I5-3570 is out of date. It would be hard to find a new motherboard to go with the old 3570. So if you are wanting to upgrade, you're going to need both the CPU and GPU, especially for Star Citizen.

Question #3: As far as the Intel CPU and Gigabyte Z590 motherboard combo, we have no answers on how long your PC components will last. We have no way of determining that.

PC parts last as long as how the PC user uses them. So if a PC user is abusing the PC by overclocking, downloading and installing unfamiliar software or doing windows configuration that they may not be fully understanding, things like this over time can deteriorate a pc and its parts.

How long did your current pc last? Just curious.

Question #4: PC building tips. Hmmm, definitely watch some "How To Build a PC" videos on You tube. Below I've including a link on your wiring. Your motherboard should come with instructions with a layout, but that may be a little confusing if you have never built a pc from scratch.

No worries you can always google what certain ports are labeled as, what they are for, and what should go into its port.

And of course you can always post a question here, or send us a chat or text on help with your build.

Good luck

@myLord95 Sorry for the confusion. Yes your SSD will work, but you may still have an issue of booting to windows on the new pc with the 128gb SSD. Again steps can be taken to try a different boot modes such as Legacy or UEFI to see if the motherboard will boot the 128 SSD to windows. It may work, it may not.

You're good with the GTX 1060 as your GPU.

For the PSU extension kit, not sure what is driving for this to be part of your selection.

Is your current PSU missing some cables? What PSU do you currently have (manufacturer and model)? I can google it and see if you'll need the extension kit.

An area to look at to cut back on costs is your case fans. Looks like the NZXT H510 case should come with 2 case fans (intake & outtake). That should be efficient enough for what you have described as how you'll be using the pc build. Now if you plan to overclock, then I'd say stick with the case fans you've chosen.

Everything else you've chosen looks good. Only thing really was the cooler; overall a good selection of parts.

@myLord95 no problem, glad we could give some insight to you off the Microcenter Forum.

Good luck on the build.

Post again if need our assistance.
