I've removed it but before i go out and find another to replace it, what would happen if powered the PSU up without it? The big capacitor in the PSU was blown. Given how expensive of a PSU yours is i would be willing to bet money your components are fine. lol, i had the privelage to experience a blown PSU took out my mobo and everything that was hooked to it. Check for blown capacitors: Capacitors You got a blown capacitor and probably a couple diodes inside the PSU. Their PSU's are built tough and will last you. Identifying a blown capacitor Now, the case of the capacitor blew against the case of the device, so the cap couldn't 'explode completely'. Jul 31, 2020 #1 My PC just made a loud bang (can't tell for sure, but it did sound like a capacitor exploding) and turned off immediately after, but it managed to boot Okay, firstly I'm not 100% sure the psu capacitor exploded. It's nearly always a secondary capacitor that blows in a PSU and those are used to control ripple on the outputs. However, all signs point to that being the case. Strange Noises Or Odors: Unusual Sounds Or Burning Smells As Indicators. The top of a blown capacitor will be slightly bent outwards in a convex shape, rather than flat or slightly indented inwards like a working capacitor. This blown capacitor is a follow up to a twice blown, twice replaced bigger capacitor. But I heard once that there's acid inside the capacitor. Blown Capacitor Blown PSU capacitors Corsair CX750 Explosion Toggle sidebar Toggle sidebar. too much unknown left in there. You can actually repair it easily and cheaply if you have a solder kit and know how to de-solder and solder things (depending on Motherboard is done for. you do not know if capacitor damaged other components you do not know when next capacitor or component will blow any blown components in PSU can allow harmful voltages/currents to get to rest of computer. Its the AC part of the PSU that got blown up, not the DC part which went to your rig. 2 - Blown capacitors 3 - Capacitors lost capacitance 4 - Octocoupler is not workin 5 - Zener Diodes / Diodes broke Q2 - I Can't repair my psu, i can't find a replacement, what do i do? A2 - You can buy an external PSU with the While swapping out blown capacitors in older electronics is something of a rite of passage for the fastest way to find bad capacitors in PSU was with an hair dryer in one hand and freezer on If a capacitor is blown, you will visually see it. (see picture taken from the Net) Now check whether an electrolytic capacitor has "blown up". I used a flashlight with it on and can't see any smoke, but the small is strongest at the PSU. Depending on what the capacitor in question is actually doing, you may not see an immediate impact (as you noticed), but things will degrade, and what's worse is that the other capacitors are likely to start failing Regarding everything else being intact. you will see many capacitors with Nothing at first, then the small started again. Anyway, what do I do now? Of course, I need to replace the capacitor itself. Get 800W or 1000W so your no where near stressing the PSU and do not use the system in thunderstorms. Here is a list of known crap brands. I would look for new PSU, no offense to repair skills but. The new electrolytic capacitor must have the same capacitance and voltage. Long I experienced a catastrophic failure with my PSU where it appears a capacitor literally exploded and blew apart into the PSU fan. Commented Jul 21, 2014 at 8:25. If it is smoke, its likely an IC blown not a capacitor. There is always potential for damage but most PSU's have built in protections to prevent damage to any of your components in the event the PSU kicks the bucket. Use EVGA, Antec, SeaSonic psu and do not get their lower end stuff. . There are a number of popular fan bearing types, but three are most common to modern PSUs When your PSU won't start, most enthusiasts don't go beyond a paperclip or multimeter check. If this surface is curved upwards, the electrolytic capacitor is defective. If this were a new build I'd take it apart and look at everything, but with older builds that could be the action that kills it for good. Because the y-capacitor has blown, the It indicates that the PSU has experienced a failure, such as a blown capacitor or other electrical issue. This can occur due to a faulty fan or other mechanical issues. Check the voltage rating of both capacitors and go with higher voltage, i. Stupid. The pc was still working after the pop and I shut down my pc after a few seconds through windows you do not know if capacitor damaged other components you do not know when next capacitor or component will blow any blown components in PSU can allow harmful voltages/currents to get to rest of computer. I've removed it but before i go out and find another to replace it, A blown capacitor is a capacitor that has failed, typically due to overvoltage, excessive heat, or aging. Hardware. The connection wires and height should also be the A busted capacitor can be obviously broken (leaking brownish fluid, corroded, or with the leads severed), but sometimes it's subtle. I've seen the popular name You look at PCs from 20 or 30 years ago, and there's a good chance that you'll find some with bulging/blown capacitors. – LPChip. Hi, A capacitor on the PSU - PW808 get very hot recently, burnt out really, I was considering replacing it, but wasn't sure what the specification are, it was item C2 and it maybe affected C3 also any parts list or something specifying the capacitors required?
