The Antec TruePower Classic is a very good unit.

Awesome, ordering now, thanks for the help guys.

Hi, I own a CX500M, and I bought it when I was newer to the world of PC building. I've had it since September 2015, and it's currently running on:
4790K @ 4.0GHz
GTX 960 4GB.

Do I need to throw it away as soon as possible and screw trying to save for a second PC, or is it okay where it is for the time being, maybe until September?

No one forces anybody to do anything. It's your decision what you want to do with your power supply. We cannot really know what will happen when it fails because there are so many things in a power supply that can fail. So, it's your own free will.

Its fine as long as you arent trying to overclock.
You are not using enough electricity with that setup to stress your power supply.

Its certainly good enough to last for the rest of the year and then some more.

 

[tiny voices]

I wouldn't really worry about it. It is not that bad of a unit and will be fine in that PC.

It should be able to handle an overclock. Overclock any hardware, and the PSU will have more stress on it, and its lifepsan will be decreased. That's a drawback of overclocking anything, better performance for less long-term stability. Overclock a GPU, a Seasonic Platinum's life will decrease. The only time I'd recommend not overclocking seriously is if the PSU is one that blows up and does not have working protections. Or if the stress + heat results in bad voltage regulation from derating, but that's why we have over-temperature protection, is it not.

Also, I think you mean "energy" not "electricity" 😉

One of the definitions of electricity is a type of energy. Please quit with trying to re-assign accepted terms; you will cause *far* more confusion than you'll solve.

I think the EVGA G2 series should be demoted to Tier 2 for it's cheating mechanism on old hold-up time tests, where it drops the PWR_OK signal at 10.8V.

Nope. Can't do it. Sorry. Ain't happening. Ingen. Nein. Non. ʻAʻole. Nihil. Nie. Hakuna. 沒有. And no sireebob.

Hi all...I am new to the forums...i didnt know where to write so if this is not a place for my comment then the admin may feel free to move it elsewhere....

TO my question...

i have this rig:

i5 760 10% oc (auto oc from mb)
gigabyte 5850 oc
Asus p7p55d-e
2 stacks of 2gb 1600 kingston fury
1 stack of 4 gb 1600 kingston fury
1 hdd WD 500
1 fan 14 and and the cpu cooler
and last the reason i am writing....Thermaltake toughpower 700 w cable managment 4X12v rails 56 A combined(i bought this back in 2010 with all the above)

Now all this run till this moment great.,,,but as the time draws late i need to upgrade ....

i am thinking of starting with a r9 390 or a r9 490 if the price is good in a couple of months...and continue later in autum with the rest..
i write also what i plan to buy next..

it l be a i7 6700k or 5850k
Asus Z170-A or a X99-A
16 gb of ddr4
i ll keep the hdd and buy a ssd samsung 850 pro 128 gb...

so....can my old psu handle the new gpu i plan getting...or should i buy an Evga 750 g2(keep in mind that i am for now at a budjet which barely can buy an r9 390 or 490 in june)...thats why i am buying piece by piece...and if it can handle it, can it handle the rest system i plan in the near future? Thank u all in advance...

You'll want a higher quality power supply. I don't recommend the G2 series anymore (read).

First and foremost, you'll want to upgrade your CPU if you're getting a GPU that good. It's too old. As for the PSU FSP Hydro G 650W would be a good choice.

Also, do you have a link to your exact current PSU? There are a gazillion different Toughpowers.

There is nothing wrong with the G2 series , they are some of the best on the planet , would me a great choice.

I own G2's and P2's they are fantastic.

Dropping the PWR_OK signal at 10.8V is what's wrong. I own G2s also, and I'm quite upset since this information was revealed. To quote Aris:

The hold-up time tests don't go well. Not only is the measured hold-up less than 16ms (the ATX spec's minimum), but the Power_OK signal drops after, and not before, the PSU's rails go out of spec. This means that your motherboard gets a false power-good signal from the PSU. Indeed, we measured the +12V rail floating at around 10.8V when Power_OK dropped to zero. This is a very low voltage level that applies lots of stress to the voltage regulators of components fed by +12V.

In a high-end PSU like this one, we didn't expect such nasty behavior. We have to admit that we're very disappointed by Super Flower's decision to drop the power-good signal so late, which is probably done to give the false impression that the hold-up time lasts longer. By the end of our review, this is going to cost to this PSU a lot of performance points. Whereas it might have received an award for performance, there's no way it will now.

I have an 850 G2 and a 550 G2; the 550 G2 we know for sure has this problem, and it also seems the P2 series has it (so likely the rest of the G2 series, too).

If you want to discuss full system upgrades, start a thread. This thread is for power supply discussions. I've never had an issue with any G2 unit, regardless of what the hold up time results may be on his test bench. I for one would like to see this tested across multiple units to ensure this isn't something that was only a problem on that particular unit, because I haven't seen this indicated on any other review.

Hi, I'm seeking for a power supply with 500-600w, I've seen good reviews on S12-II Seasonic 520w but they're from 2010, is it still trustworthy to invest on it?
Also interested in XF TS 550w(80+ Bronze), which one do you suggest?
This is my current build http://pcpartpicker.com/p/YQGh6h
Appreciate your time

 

[Darkbreeze]

The XFX TS unit is Haswell/Intel low power state compatible, the S12II 520 and 620 are not. They can still be used if you turn off the C6/C7 states in the bios but the XFX unit is probably a better choice since you won't need to do that.

A bunch of companies are doing this to cheat. Look at this Zalman unit which drops the PWR_OK signal at 10.24V! That's extremely dangerous.

The PWR_OK signal is a value defined in a circuit, it wouldn't mistakenly just happen to be 10.8V. Hardware fault won't change the value. Sirfa primarily does this, and I guess now Superflower.

Not sure if any other G2 units do it besides the 550.

Sorry, didn't understand you well can you explain it in another way?I'm using a skylake cpu

Group regulated power supplies like the Seasonic S12ii cannot maintain stable voltages when crossloading. The sleep states make the CPU use virtually no energy, so you're looking at about 1W on that 12V rail (which powers things like the GPU and GPU) being utilized, while the 3.3V is still working because of RAM, and the 5V rail... not sure.

But anyway it's this really low 12V load that causes the 12V to go whopping high or the 3.3V and 5V rails to go whopping low. Units that do not have a group regulated design don't have this problem, and are compatible with those super low power sleep states Haswell and Skylake CPUs have.

 

[turkey3_scratch]

I think I'm going to go to Microcenter today and buy two power supplies:

Diablotek EL 400W
Solid Gear SDGR-400BX 400W

Both are $11.96. These will be my next review units.

Get the XFX TS 550w over the S12II 520/620

Also i didnt started to talk about new rigs....i just want u to tell me if my current psu can handle firsty an r9 390 or 490 and secondly when i proceed buying the rest parts for a new rig if the one i already have can handle them....and if not , i want to know if evga g2 750 is good and , what other units do u recommend...(not much money ...100-130 euros...evga here in Hellas has 125)
