I took a nap with my computer left on, and when I woke up, it was off. It does not turn on or do anything at all when I depress the power button. In my mind, I went through a checklist of possible reasons for malfunction. The cause could not have been a power failure, because the power was on at the moment, and it could not have been a power surge, because it was surge protected and other computers in the house were working perfectly. So, when I reset the power strip a few times and flipped the power supply switch a couple times, I decided to open it up.
Inside, there were no busted capacitors and all power cables were connected correctly. Nothing interesting was found except for a lot of dust. Then, I decided to look into the power supply, and in that I found a certain ceramic capacitor that had cracked. Could this be what has brought my rig to its knees?
Well, if it makes it any more likely, the power supply came bundled with the case I bought for 40USD. The model, to be specific, is a Raidmax RX-420K It was cheap, but it worked. Some research was done and apparently it has failed on other people. But the thing is, it was only rated for 420 watts while I was recommended by Newegg's calculator to have a power supply that can handle 450 watts.
Overall, could the fact that the computer won't turn on spell damage to my files? Also, are there other possible solutions that I failed to take into consideration? Is it really a power supply problem, and if it is, did the power supply wreck the motherboard?
Please help, and if pictures make it easier, I'll post some.
Thank you in advance.
Yeah, while those things are undoubtedly good, they are unduly expensive IMO, especially as nothing can really guarantee reliability. It's just that some makers are more likely to be more reliable than others. And Seosonic, Antec, XFX, Corsair all fall in that category.
Dunno your specs, but Raidmax, Rosewill and especially Coolermaster are definitely vfm.
It's impossible to recommend a PSU for you without knowing your configuration (gfx card, case), because of not just available amperage ratings, but also compatibility issues with your case, and connectors required for your GPU.
