Did you use the same, or any, power strip, with it set up in the kitchen as what you were using when it was connected in the other room?
Your PSU should be directly plugged into the wall. It should not EVER be plugged into a "power strip" or "surge protector" unless it is a high quality industrial type unit rated for 15-20 amps. Monster, Belkin, Amazon basics, Walmart, Lowe's and other cheap branded units are not recommended to be used AT ALL. Ever. Not if you value what is plugged into them unless it is something like your monitor or a lamp, but even then do not plug into them thinking they offer any actual protections. All they offer is convenience, that's it. The "protections" on most power strips, labeled as "surge protectors" is literally almost non-existent.
If you want to use a power strip/surge protector, you need to spend the money on a reliable, high quality unit.
APC, Tripp-Lite, Leviton, Eaton, Leviton, General Electric, Polyphaser, Ditek, Siemens, ABB, Square D, Intermatic, Cutler-Hammer (Eaton), and Syscom, these are the brands you can trust to have high quality internal electronics if you MUST use a power strip. Do not however use a power strip thinking that it offers significant protection, because even the best of them does not, not really. Whole house protection is the only real protection from surges.
Monster and Belkin, and a few others that are commonly used, almost unilaterally use the same protections in their 45 dollar surge protector strips as what you would find in an 8 dollar Amazon or Walmart branded model. And if you ever take one of these, or any cheap box store, dollar store (Even worse than these others usually BUT occasionally about the same) or Harbor Freight power strip apart you are likely to find frayed wires, poorly soldered connections with blobs of solder nearly touching crucial and potential short circuit points, super low quality MOVs, and a ton of other indicators that no real integrity was involved in the design or manufacturer of these units.
Another factor to keep in mind is that even with some of these high quality units, any protection that MIGHT be afforded, is usually the end of that product after one shot. This, directly from the Tripp-Lite manual for the #1 selling surge protection power strip in the world.
All models feature an internal protection that will disconnect the surge-protective component at the end of its useful life but will maintain power to the load now unprotected.
I believe many models from APC and a couple of the others I listed have now incorporated designs that permanently disengage any ability of the device to deliver power once a surge or short of significant enough caliber to incur the protection has occured. That basically means once there has been a surge or short, throw the device away. Even for high end models. Only whole house protection and properly earthed circuits offer any true protection from a serious surge or direct strike from lightning somewhere close enough to affect your segment of the grid.
And whatever you do, don't EVER buy any kind of extension cord, power strip or other electronic device with slip rings.
A few weeks ago I needed a power strip in my home office. The outlet in question is located behind a filing cabinet so it would need a low profile plug. I jumped on Amazon to buy a surge suppressor…

If the problem is NOT related to a power strip, because you are still getting the same smell without using one, then the FIRST thing I'd do is pull the motherboard and make sure that there is not a standoff located in a spot under the motherboard where there is no matching standoff hole in the motherboard. This is actually something we see fairly often even if it isn't particularly common, it happens. Especially if the standoffs come preinstalled and you don't specifically check to ensure there are none installed for locations that your board doesn't require.
After that, I'd pull every connection to the motherboard or power supply and make absolutely sure none of them are 180° backwards or off by one pin. For fan connections, that can be easy to do and not even know it. Connectors that are not QUITE fully seated can sometimes heat up or arc as well, and when warm the plastic insulators can let off a little magic smoke or stink.
Next I'd check for any leaking or bulging caps on the motherboard, or any visible signs of heat damage anywhere on it or on anything else and if you come up with nothing I'd return that power supply and buy something worth having as that unit, really isn't, and there's a good chance it could be the source of your problems since it's not actually built by Super Flower and is farmed out to an outside manufacturer.
