My maid flipped the red switch on the back of the cabinet (on the PSU), where it says 115/230. It was 230 previously and she switched it to 115 while cleaning by mistake. Ok, let me stop with the lies, I did it :rolleyes:. As soon as I pressed the power button, I heard 3 pops and some burning smell. I know it's the PSU as I have got it checked from the repair guy. The PSU is 6 years old and the burnt components are not available anymore. Here is my configuration:

PSU: CoolerMaster RS-400-PSA-I3 (ATX) :(
CPU: Inter Core i3-3210 (LGA1155)
Motherboard: msi ZH77A-G41
GPU: Nvidia GeForce GT 620 2 GB
HDD: 500GB SATA WD-Blue
RAM: Corsair 4GB 1600Mhz
Cabinet: CM Elite 371

All I know right now is I need a 450W or above PSU with ATX form factor.
Why above? I want to upgrade to i5/i7, another 4 GB graphics card (so I would have 2+4 = 6 GB) and 8GB DDR3 memory (so I'd have 4+8 = 12GB), in near future. I was using this desktop for normal gaming such as CS:GO, LOL, other FPS games, movies, some very basic video editing. This was bought as a gaming PC 6 years back, but LIFE (early 20's :censored:) got in the way. I know I can find the exact wattage of these components via an online calculator (which I did and it came out to be around 600) but I wanted a veteran opinion because brands do not perform sometimes and this PSU burning incident, is my time to get it fixed and start gaming again as my life is pretty sorted now. Good folks, please assist and add your credit score for heaven 😇. I have Assassins creed, Dead by Daylight, Witcher on my wishlist to play next.

Good. You should have never been using that PSU in the first place. Just the fact that it had a 115/230V selector switch should have been a warning sign.

As @vapour asked: What's your country and budget?

Ok. Also I can spend some extra money for CX550 but only if it is worth to support i7 and dual gpu. On the other hand, my motherboard can only support upto 3rd gen Intel Processors. Is it worth to upgrade to i7 and dual gpu. I feel I'll still be far behind from today's generation of builds and my system would be slow

Not for THIS graphics card. But if you were planning on upgrading significantly in the next couple years.....

Ok. What I have estimated this:
  1. i5 3rd gen: 5000 INR
  2. PSU CX550: 5000 INR
  3. 10000 INR GPU
  4. 8 GB Ram DDR3: 4000 INR
Total cost 24000 INR.

In 2019, Is it worth to spend 24000 INR to upgrade to 3rd gen processor and old gpu?
