Yeah, I understand. If I were in that situation, I would go ahead with a UPS, as it will protect the PC components & give me time to save if I am doing something. Just make sure to not exceed your breakers limits as I am already sure you know.

Well, the BEST available protection would be to hire electrician to improve the overall usefulness of your electrical system... That said, that UPS should help with your PC (will also keep it running for a few minutes if your breaker does flip), especially with power spikes, but the UPS will also have a high power draw to maintain itself, think power out means power must also flow in. It could turn out interestingly to say the least. Good luck with your setup.

Given you can actually obtain a GPU, it seems like a fairly good build. The only thing that stands out to me is the ram. If possible, go for 16 GB of ram (2x8). Some applications, specifically video editing can gobble up ram depending on the program, and complexity of edit. 8 GB could be frustrating to deal with. Also, it will help the system last for longer in general without upgrades.

Shed purposeful tears while scrolling through eBay, and then find a used low end card. Something workable for desktop use, but not valuable or powerful. EDIT: Probably some AMD HD 8xxx or HD 7xxx card. It seems possible to snag one for $40 ish, depending on the card.

It sounds like either your pump from the AIO is dead or not plugged in / setup in bios, or there isn't near adequate contact between the CPU and heatsink. EDIT: Also when installing the AIO, did you remove any plastic cover / film from the heatsink?

For CPU's, probably the R9 3900x (12 core), or 3950x (16 core, high price jump), or the 5th gen counterparts. For motherboard, you will have to lookup which ones have proper ECC support. It seems for the x570 platform, ASUS, and ASRock are most likely to support it.

I hate to say it, but if you want stable, SolidWorks isn't for you. Those build ideas are fairly good, but so you know, AMD does offer ECC support on their consumer CPU's. You just need to make sure your motherboard supports it properly.

In most situations, USB adapters for SD cards work the same way as general USB storage drives. You will likely not have any issue doing so.

Depending on the speaker, and how it is controlled, yes, it is possible they are not going to be as loud as they may have been otherwise. Is there anything wrong doing what you have done? Nope.

V-sync is a GPU feature, that limits the amount of frames to a certain level, usually 60 FPS. You must be thinking FreeSync, or G-Sync which are monitor features that sync the frames to the GPU frame pacing. Many games have V-Sync on by default (annoying in my opinion). If you are hard limited to 60FPS, this would be my suspect feature to dissable.

Have you tried lowering the clocks on the card? The card could possibly struggling maintaining the clocks for whatever reason, and you specifically mention it is an "OC" model. Try bumping down the clocks by 50MHz or so.

What drive are you using? Is it a SATA PCIe drive? Those are not supported by the adaptor, though they will physically fit into the slot. Can you send a link to the specific drive you are using?

I use this one from Amazon, and have absolutely no issues with it. There is also a much cheaper USB 2.0 version available. https://www.amazon.com/UGREEN-Selector-Computers-Peripheral-Switcher/dp/B01N6GD9JO/ref=sr_1_3?dchild=1&keywords=usb+switch+ugreen+usb+3&qid=1614591482&sr=8-3 I have never heard of the brand of the one you listed, but that may be a more well known supplier where you live. I am just wary of the lack of any reviews. If you think it is a reputable brand, I see no issues with it. As for power, I don't have to supply supplemental power (5V), as the devices I use don't draw much energy (RGB keyboard, mouse, etc), but the solution of a micro USB cable is the same for me if I were to need to.

What is the workload? If it is gaming, the bottleneck is almost definitely the GPU, as it is an aging low-mid range card. The CPU will have strong performance still, being high end for last generation. In this case, the GPU will be the first thing to replace if better gaming performance is what you are after. Sadly, however, GPU's are hard to come by at a reasonable price right now, so good luck.

Those must be selling for higher than MSRP right now anyways right? More seriously, the 3600 should be perfectly fine, especially since you already have access to one. Later down the line, if you notice your CPU usage is maxing out (per core, or overall), and performance is not where you want it to be, then an upgrade would be advisable, when parts have hopefully dropped in price.
