So here goes nothing. Last week monday I left for vacation so I have unplugged my computer from the electric socket so I won't have any surprises when I get back after 6 days .... BUT I still have ..... One big surprise ... My power supply is Cooler Master real power M850 ... I think it is a good one , as when I acquired it I did some research . Problem is that when I put the cord back ...nothing happens ... nothing , the led on the back is not turning up , power in the pc is not coming . I now it has power as I almost electrocuted myself . Also I know that it has some power failure options on the PSU , but if I have to wait 6 days for it to start back on ... I will set it on fire. So. .... does anybody went THROUGT a situation like this. If not .... can you recommend me a better PSU . Seasonic ? Super Flower ? Sirtec , Antec ????
First of all, check if its under warranty. Once its PSU fault, you should be able to exchange PSU with Master Cooler with working one. I hope you didn't open screws to void warranty.
Unplug the PSU from the PC entirely and on the large connector that goes to the motherboard, short the green wire to black. This should make the PSU power up. If it doesnt then there is either a problem with power or the PSU has a problem. If it does power up then plug it back into your motherboard and graphics card only. See if it powers up. If it does then add other hardware to it one by one. Hopefully you will locate what is stopping it power up. If it fails to power up try and get a less powerful graphics card and see if that works. If it does then there may be a fault on your gfx card or your PSU may no longer produce enough power to support your hardware. This is how most PSUs end their lives. Its possible there is nothing wrong with anything and its just a bad connection somewhere. If so, re fitting it should get everything working again. If problems continue try stripping the whole machine down, give it a good clean and re-assemble. tbh I would do this first but it depends how deep you are ok digging into a PC.
Already tried cleaning the pc ... now I have left to another city for work . I will be back on friday .... will try to short the pins when i get home.
No one else has a better idea ? Or experience with cm power supply ? I tried to e-mail CM ... but no one is answering
Considering that PSU was introduced to the market in 2006, i think its time to replace it. It's an over 10 year old design, not really supporting latest atx spec for new systems. What kind of budget are you wanting to spend on a new one?
I know it's an old design ... but it has ATX standard 2.3 and the latest it's 2.4. Also , I have bought it I think in 2009 .. to bad ( out of warranty ) .... About budget .... I think also around 150 euro ... But't I don't think I need that much power anymore .... thing is I don't know what to buy anymore ...
https://www.amazon.de/Netzteil-EVGA...=UTF8&qid=1504635658&sr=8-4&keywords=evga+650 That is one of the best gold rated PSUs you can get. 650w evga for 109 Euro 750w for 119 euro https://www.amazon.de/SuperNOVA-220...=UTF8&qid=1504635772&sr=1-3&keywords=evga+750
If your warranty is expired, I am not sure what you can achieve by contacting them. Make sure it's PSU that faulty and replace it.
I don't need a replacement ! All I need is an explanation why it acted this way ! You have to admit it's a strange behavior. I will buy another one if the short won't work.
I don't think they can come with accurate explanation without examining it. And since its out of warranty, they are not required to look into it. Cool down, if you sure it's PSU, get a replacement. Things are not build to last forever. Not related, but I had weird PC shutdowns month ago. Took whole rig apart, cleaned PSU as far I as could reach without voiding warranty and its back to normal. I don't know if dust caused overheating or affected capacitors. But it's stable so far. If you don't clean your PSU, lifespan might get shorter.
Honestly I hope he didn't open it period, never mind the warranty. Opening a PSU is not exactly the wisest idea.
If you want to keep the PC in optimum condition you should open the PSU to remove dust . No compressed air spray can clean in-depth ... just my two cent's. Thank for all the help guys. Will try to repair the PSU or get a new one. Let's see how the finances are rolling . P.s. It's EVGA supernova G2 750 or 850 any good ? I have been locking on a lot of PSU but none come close to the quality of this CM 800 that I own. Cables today all look like crap . I own a lot of cm products but I think I will skip them on the PSU front . So ... EVGA , Seasonic or Corsair ? NOW I need the real GURU's
One should never need to open up the PSU just in order to keep it in optimum condition, yyyyeah maybe after 8 years but in general, no. A good bash of canned air is fine and if it isn't use a compressor with care. Be very cautious towards opening up a PSU. You could end up in a hospital or worse if you don't know what you're doing (not saying that you don't but in case...) As you said you bought the PSU back in '09 - that would be about 8 years ago, I'd bet it's about served it's own purpose and you'd be better of just getting a new one and be done with it. Heck, 8 years of life out of a PSU in gaming usage or similar, that's rather impressive to me. I would just go with EVGA Supernova 750 G3 or 850 G3. Both are very reliable fully modular PSUs with plenty of output for future updates and whatnot. Plus both got good looking cables to go with them and a 10 year EVGA warranty, yes, TEN years. Seems to me like both of these are better in every aspect compared to your current one which you seem to believe to be a lot better than it actually is.
Already sent you the best PSU you can get for the money on gold rated PSUs. Read reviews at jonnyguru, you'll see it gets a near perfect score. CM800 is a mediocre PSU, don't think that it has any comparison in quality to new ones like evga G3
Supernova IT is then. P.s. it's not that I belive that the CM was the Best PSU , but it was a good one. Let me give you one exemple : my SATA conector has 4 outpots so for my hdd'S I use only one cable. In know things have changed since 2009 so I really want a good PSU but I am not willing to go above 150 euros. Edit : in Romania In can't find the G3 version. As far as I serched the only difference would ne that the G3 ia shorter . anything else ? Think I would go with the 750 w supernova. Should be enough for my phenom and the 970 . Is this power enough for a ryzen ? Maybe will upgrade next year?
4 sata on one connector is very common, that has no bearing on quality of PSU though. Don't get any regular supernova. The original ones aren't near as good as g2/g3 G2 evga is also a good option, g3 is a newer platform with better efficiency. Do you have a website i can look around at for recommendations?
The evga P2 650 supernova is 584 lei, i take it thats too much? But i did find the G3 550w, which honestly is plenty for ryzen + 970. http://www.cel.ro/surse/sursa-modulara-evga-supernova-550-g3-550w-80-pluss-gold-pNSYxNj0v-l/ If you want 650w, the seaonic focus PSU is also an excellent option. http://www.cel.ro/surse/sursa-modulara-seasonic-focusplus_-650-650w-80-pluss-gold-pNSYyPD0n-l/ Both PSUs are practically as good as it gets
Thanks for helping me ! Sorry If I was a Little stuborn but I like to make an informed decision when I buy Something. Max I will go ia 650 Ron - so 150 euro . Thanks again
