Hello there dear tankers, and tanks for peeking into this article :D i would like to know if my PSU is ok or shall i change it....
According to my Bios, the +12V rail is around 11.332V, and that is Below the minimum suggested for it (11.400v), Also the +3.3 is around 2.818V and the minimum is 3.135V, but i dont notice my computer were going to explode : | the only thing i noticed its that my HD5850 is a bit more Hot than usual, just a few more cº than usual.
What do you think Tankers, shall i replace it?
resume:
Normal: +3.3V  Mine:  2.818V
Normal: +12V   Mine: 11.332V
http://forum.worldof.../Smile_ohmy.gif
PC Configuration:
Phenom II 1090T
8gb ddr3 1600mhz corsair
2x1Tb WD Caviar Black
PSU: CoolerMaster extreme power 600W
MB: Asus M4A87TD/USB3
6x 120mm Fans
and one dvd rw.


EDIT:

i have this psu at full power most of the gaming time, its actually round 85% Gpu in wot, so i can imagine the psu worned out with the time, it is around two years now...so i think its time for it to be replaced ;(


However, i have few choices due to my $$, i can  buy another CM EP 600W, or a ThermalTake TR2 600W or another thermaltake Toughpower 600W, and if i sell my actual PSU, and give up my limber, i could get a COOLER MASTER SILENT 600.


Which one do you advise to me?

In the second Pic it says your System temp is 49°C..is that the Temp of the PC or just the CPU?
If it's the PC, the you should do something about that.
Maybe that will help a little  bit, because the more power the fans need, the less you have for the rest

Naaa, as long as it runs stable it should be fine. Maybe your bios just shows low values. Have you tried checking with a prog in windows?

Well, it is usually the Watts that matter I think, and 600W seems to be OK. The Voltage is only 20% or less below stated too, which is normal due to inbuilt PSU resistance (you never get 9V out of a 9V battery either!).
Don't worry and continue using it unless your system encounters frequent crashes (BSOD or full system shutdown with no warning), and in frequent I mean more than 1x a week.

CPU temp is around 40-42 with wot, so i think its perfectly fine, no? that one is like MOBO temp....

Please stop posting bullshit like that - if you have next to no knowledge of psu just keep quiet. If a psu fails, often the other parts of the pc get damaged. a good starting point to gain some knowledge regarding psu would be jonnyguru.com or tomshardware.com - many reviews and some explanations how psus (should) work and what to consider when buying a new one.

how much money is availble on your side? (you dont need a 600W psu - a good 500W psu is more than enough) and where do you come from - so I can give you some links. no use if I post links to german sites/stuff if you come from GB for example.

im from south america .___. and they all cost 100USD here, but the CM silent 600W cost 145USD.....
CM EP 500W = 66USD
CM EP 600W = 102.5 USD
CM Silent 500W= 102 USD
CM Silent 600W= 143USD
or rather a Oxxon 500w= 16.5USD xD http://forum.worldof...mile_blinky.gif

What about a Seasonic M12II 520-Bronze 520W???

Antec High Current Gamer  HCG-520 ????


The PSUs you listet are propably all better than the current one (exept the last one) - problem for me  is the naming scheme, its seems different than the one in europa. could you please give me link to a price comparison site where those psus are listet you are speaking of?

Personally I like the ThermalTake series of PSU, my last one ran constantly 24/7 for 5 years straight, just got a new one about 3 months ago, and it's even better than the previous one. But despite Folterknechts info, well, in all honesty most PC do not hit max load unless they have a hell of a lot of equipment plugged in. Nonetheless, the coolermaster is showing some weakness, so before you sit in front of a PC that doesn't start it wouldn't hurt to replace that PSU.

I have the Toughpower XT 775W, my PC stays on 24/7, and I am happy with its noise level (or lack of noise!) and it provides plenty of power for my system, which has 2 NV560GTX and 3 DVD drives and 4 hard drives plus all kinds of stuff plugged in.

I have a Seasonic X Series 560W semi passiv. It is absolut quiet with my i7 + GTX580. The whole system take 365W with Watercooling, so the PowerSupplys fan nearly never runs.

@sgt_bones:

Seasonic and FSP are 2 of the few firms that actually build the PSUs themselfs. Corsair, Thermaltake, Antec ... let their PSUs build by other companies. Thats why I m always sceptical with those "brands" until I find info who really is behind a specific psu and what quality its made of. The Antec I suggested is made by Seasonic and received good critics.

If you rate a psu 600W and it can only deliver 450 W its scum - nothing less. Also keep in mind that the review samples are sometimes "cherry picked" meaning those you actually buy in a store sometimes perform even worse. Add aging and insuffiecent protection against failures to mix and you have a recipe for disaster

@riechochs:

The X-Series is very good  - but out of reach for him budget wise I think. Personaly I m not a big fan of those (semi) passiv psus. Technically there is nothing wrong with them in most cases. The problem for me is that I wont recommend it to any user I personally dont know and cant instruct/help. The problem is dust, which can lead to overheating, if the psu isnt controlled/serviced properly.

I know a thing and two about PSUs from experience and school (computer technician).
First of all - the volts will never be perfectly at 3.3, 5 or 12. It depends on the demands of the system and the way electricity works. It's hard to explain, and the fact that I don't remember what exactly the professor said, but it's normal and has been taken into account by the manufacturers.
But I can see that your voltage is a little under, in my opinion. But don't fix what doesn't need fixing - the PSU has built-in safety features - if the voltage will get too low or too high, it will automatically shut down.
Don't want to buy a new PSU, but don't want to take the risk - buy a PSU tester. If all of the lights on the tester will be green, your PSU will be fine.

Did you actually read what a linked:

"The Cooler Master eXtreme Power Plus 600 W, like the 550 W model from the same series, can’t deliver its labeled wattage. The power supply immediately burned when we tried to run our 600 W load pattern"


That alone is proof enough that there arnt safety features in this psu or the dont work as they should. So please  stfu ...
and those psu testers (for home use not professional ones like from croma)  ...  :facepalmic:

Those prices comes from my Hardware Provider, call them, "the Dealers". They are importers like anyone else, and in my country those two companies (CoolerMaster and ThermalTake) are the only ones available, because my country "imports" what its "cool" and "cheap" not what is expensive and good, or at least Good. there are specialized hardware importers, who sell whatever you want, but adding around 50% more to the real price.
if you want a site to view prices, there is a fake cheap copy of Ebay here, called Mercadolibre, a beautiful Ghost Town. MA as we call it.
The place is filled with PSU saying to be 80 plus, but they are fucking cheap china copies http://forum.worldof...y.gif,  Sentey? Codegen? Gigabyte? FFS, they are all toys! how can they sell a 80 plus PSU for 80usd? that is bullshit .____. i know for you its ok, but you must remember than they add 50% to the real price... you can check a more precise search here: conditions: near center of country, over 100USD "New". The currency conversion is simple: 1 USD = 4.55 ARS(my money)

If you have enough money for that coolermaster silent 600W (good psu a little "outdated") go for it  ... I have the 500W model here at home as a spare part (like to tinker with PCs), they are good and nearly silent.

here are some reviews:

http://www.hardwares...ly-Review/929/7

http://www.jonnyguru...Story4&reid=134

you realy seem to have not many choices or they are too expensive and even the price for that CM silent 600W is high ....

Thanks for your time into researching all this Dude! Its a regret that we have PSU from the 2009 here, and i tell you, we would always be 2 years behind....http://cdn-frm-eu.wa..._sceptic.gifAnd well, its normal for us, i mean, we are no third world country for anything! *sepuku*

Some general stuff I noticed. The numbers shown in bios about Voltage are nearly always wrong. There is always an offset in it, so the real Voltage could still be ok.
To really test your PSU you have to take it out and measure it yourself with a multimeter.

Another thing is, you dont need 600W for your system. 500W is more than enough for you.(Google PSU calc and you can do the math yourself)
Next thing, Thermaltake is considered a rather bad brand for PSU´s... do the research yourself on this one.
