Hey guys,
Let's get straight to the story...
So 2 days ago I was gaming as usual on my PC that I built about 2 years ago and at night when I finished I turned it off. No smell, no crashing, nothing extraordinary. Yesterday morning I went to turn it on and the PC powered on for about 0.5s and then off again. I didn't think much of it at first, so I tried again, but same thing... I went on to google a bit, I reseated the MB and CPU power cables, took the CMOS battery out and put it in again after a while and cleaned off any dust in there. The PC turned on as normal. I claimed victory and went on to browse the webs, but then all of a sudden the computer turned off after about 3 mins. Now when i got my head closer to the PSU there was this burning smell. I figured the PSU had died, It's a Corsair HX620W modular... (year 2006). I took it out and opened it up (the warranty is long gone anyways) and sure enough, there was a blown out capacitor.
Now I will be buying a new PSU anyways, but the shops are opening on Tuesday. So I called a friend and he let me borrow his old Spire 420W PSU just for the 2 days. Today I picked it up, installed it and the PC turned on fine, until after about 3 hours of gaming it shut down suddenly and the same burning smell started coming from HIS old PSU. I checked again if the smell is actually the PSU, but it undoubtedly is, smelled that way even when I took it off and the rest of the PC didn't. His is also out of warranty, so I looked inside, but everything there seems fine, nothing leaked, nothing melted.
Now do you guys think the smell from the first one was from it blowing and the smell from the second one was from me overloading it (it was a jump from a 620W one to a 420W one, the GPU has 500W recommended), or is it possible that something else went bad in my PC that affects the PSU, if so, what could that be? i wouldn't want to buy a new PSU just to blow it up or find out it still does this.
My specs:
Case: Cooler Master Storm Trooper Window
Motherboard: ASUS Z170 Pro Gaming
Processor: Intel Core i5-6600K
Graphics card: Sapphire Radeon R9 380 Nitro 4GB
PSU: Corsair HX620W
RAM: G.Skill RipjawsV 2x4 GB
SSD: Samsung 850 Evo 128 GB
HDD: WD Blue
+ ROG front base
Also, wasn't overclocking anything at the time this happened, didn't change anything, just a regular day. I should also mention that the temperatures of the CPU, GPU, motherboard were normal (CPU 25 - 50 °C, GPU 40 - 60 °C on idle and under load respectively).
Thanks in advance for any answers, cheers.
