Random reboot/Corrupted CMOS.. Leaky Capacitor in HIPER PSU

post #1 of 7
Thread Starter 
Yesterday my computer cut off (sig rig), and when I went to boot back up it was apparent that my CMOS was corrupted. I cleared it and everything worked, but, I got a very faint whiff of something from the PSU... So, thinking something is wrong with a capacitor, I opened up the PSU. Sure enough, one of the big 200V caps had a tiny bit of shiny brown crap just below it.

I should note that I've been using this PSU for almost 4 years, and I have always overclocked the E4300 to around 3GHz. Although, recently I got a Hyper 212+ and I've been pushing it a lot harder, up to 3.4Ghz. The PSU is a 580W Hiper, but only has 18A+20A 12V rails, and I can recall Phaedrus stating that these Hiper PSUs used low-quality caps.


So.. is it safe to assume that the caps in the PSU are what has been causing these problems? (Random reboot /corrupted CMOS). Maybe it's a silly question, but I've never experienced this before and I was very surprised when it happened. It does seem to make sense since I stressed the PSU harder than ever recently. The amount of electrolyte that came out below the capacitor is very, very small.. but I am assuming it's enough to cause big trouble.

Would it be worth it to replace the 200V caps? I am the sort of person who likes fixing things if I can save some cash, and I've done a bit of soldering before, but I have never worked on a PSU. I looked it over pretty good, and all of the other caps seem fine (to me)... but I figure I should ask the experts and post a pic since this isn't exactly my area of expertise!

Anyway, I would appreciate any help.. thanks!

If it's 4 years old, and it has low quality anything, I wouldn't risk replacing the capacitor, or turn the computer on again with that power supply. You need to get a high quality power supply from a known brand (like corsair, seasonic, or antec). If a psu fails, it can fry your whole entire system. Don't risk it.

Hiper Type M 580W. It's a 450W by today's standards, but aside from low efficiency it's decent enough.

The primary capacitors can be replaced, but I can't guarantee that there isn't other damage. What's the uF rating of the capacitors? You can get Rubycon replacements for a reasonable price. And by the way, those are 400V capacitors.

That is definitely smart advice, but, this system really isn't so important anymore. I have a new P8P67 PRO/i5-2500k system that will be up in 2 days, and I have a laptop, which I am typing this on. So, I think I won't mind too much savings some cash and taking a chance with it right now. That is, unless you saw something else that could be wrong... I sure didn't, but I wanted to see if anyone else did.

Oh, I know that. I guess I just wanted to know if anyone else could spot something that was obviously wrong with the PSU. This little guy has always served me well, so my thinking was that if I replaced the big caps I could get some more life out of it. I'm always up for saving $75+ if I can.

I do have to say, the leakage really is very very small... but, even this is enough to cause big issues, right? I haven't seen anything that looks bad on my mobo.

1000uF. And it seems to me that it says 200V. Is this unusual? I don't know too much about PSU internals.

Sorry, there was a hair or something in the original pics that made it look like a 4 there.

Nothing unusual about 200V caps, usually either 200-250V or 400-450V caps, depending on the design used.

Yeah, there was, I removed it in the second pic.

Anyway, thanks for the info. I think I'll temporarily use a Corsair HX650 in here until my other parts arrive, and then I might see if I have any luck fixing this thing.

One interesting thing to note is that the M 580W has an uncommon topology. 90% of ATX power supplies use either a double forward or half bridge topology, with a smaller number using single forward, full bridge, and other topologies. This Hiper 580W is the only ATX PSU I know of this decade that uses a push-pull topology, which is derived from the flyback topology (sometimes seen in laptop chargers; rarely in ATX PSUs).

It generally has a lot less switching noise than flyback converters, and is more efficient, but is still less efficient than most double forward units, which make up the bulk of enthusiast power supplies (though LLC resonant half bridge converters are becoming more popular).
