Buzzing sound & spark when I plug in power cable

post #1 of 35
Thread Starter 
Hello everyone.
So today I noticed that whenever I moved the computer table the PC would turn off. After checking it out, it seemed like whenever I would move the power cable in the PSU ( like trying to plug it in to secure it ) I'd hear this electric "ZZZZZZZZZ" sound and I'm pretty sure I'd see a small spark inside the PSU or around it ( I could see it just by looking at the PC from the back ) and the PC would turn off.
So I decided to take a look at the inside of the case, nothing looked suspicious. But now the PC won't even turn on. I plug the cable, the zzzzzz and spark thing happen and I got slightly electric shocked when I touched the PC near the PSU. If the PC even responds, the power button turns on for less than a second turns off. Most of the time it won't even turn on tho.
Does this mean that the PSU is dead? I tried with another power cable and another plug in the wall to no avail. If that's the case, is Seasonic M12II EVO edition 620W or XFX Pro edition 650W good alternatives? You can also check egprices.com if you wanna recommend something else since I'll be buying locally.
The rig is in my sig.
Thanks in advance.

Your PSU was not very good anyway so thats not a huge loss.
And you dont need more then 450 watts for the system you have under your sig.

So that's a definite sign that my PSU is done for? No way to fix it?
And can u recommend any certain PSU? I'm a noob when it comes to PSU's and I know you can't just go by the wattage written on the box.
Something that's enlisted on egprices.com would be greatly appreciated.
Thanks for the help.

Your old HEC unit is not worth spending as much as a second of your time on, throw it away and replace it even if it still works its terrible.
And why does egprices.com dont have as much as single unit below 650 watts???

The thing is I live in a small city in Egypt where there's not many PC parts available and shipping from some place like amazon to here would cost a good amount of money it's not worth it. So that HEC unit, while it's not good enough by the standards of someone who can get his hands on the best Corsair, Antec, Seasonic etc units easily, it's one of the best ones I could find.
As for the below 650W thingy, I have no idea. But if you have another recommendation other than what's available there you can tell me here and I'll try to look for it.
But do you think that the PSU is fixable?
P.S : There are PSU's as low as 300W listed. Here : http://www.egprices.com/en/category/computers/power-supplies?cat=1&sub=18&sortby=price_asc
P.S.2 : Seasonic S12II 520W. I think that one is decent but I hope I can find it locally. What do you think?

No i dont think the PSU can be fixed and you should not even try if it was worth wasting time on which its not.

This is the cheapest unit on that site that is not a major turd
http://www.egprices.com/en/product/seasonic-s12ii-bronze-520w-80-plus-certified-psu-maximum-hardware

There is also the XFX version of the same S12II platform
http://www.egprices.com/en/product/xfx-proseries-core-edition-550w-full-wired-psu-80-plus-bronze-compu-trade

If you want something a little bit better and not mind the high fan noise there is this
http://www.egprices.com/en/product/seasonic-m12ii-620w-evo-edition-620-watt-80-plus-bronze-full-modular-psu-el-nekhely-technology

This one is a little bit better still
http://www.egprices.com/en/product/evga-supernova-750-b2-bronze-psu-el-badr-group

If you want something really good there is this

High noise would be an issue so I would stay away from that.
Do I really need to go 600W+ on this rig? I think the Seasonic 525W or XFX 550W will be good enough. It's worth mentioning tho that the seasonic has pretty good reviews while the XFX is reported to have some regulation problems on the 12V rail when the PSU is taxed. I'm kinda leaning towards the seasonic because of that. Which one of the 2 would u recommend?

Excuse my noobishness, how are they the same unit if they have different power output? And if they're the same should I just go for the cheaper ( the seasonic in this case )?

XFX dont make anything they buy their units from Seasonic and the Core Edition aka TS is the Seasonic S12IIB in another box but its the same platform used in both.

The Seasonic S12II 520 watt is not even a 520 watts unit its a 480 watt unit as thats the amount the 12v rail can do.
The 550 watt XFX is a 528 watt unit as thats the amount the 12v rail can do.
