Good evening, I am in a dilemma between 2 seasonic the core gm 650 and the focus gx 550, they cost around 90-100 € each. My system has an athlon ii x4 640, 12gb ram and an rx 550 4gb, I will do within the year upgrade to ryzen and later to a new gpu (~ 150-200 €). The current power supply is about 8-10 years old no name brand, that's why I will change this first.

I know at this time 550w it's overkill, but both cost the same. The biggest plus in gx for me is the hybrid fan mode (less dust), on the other hand with the core gm I'm getting 100w more, the only negative thing in this is that the fan has only 25,000 hours of life and within 5 years i will reach this number. Is there any case for this fan (sleeve bearing) to hold longer without acting like an airplane or not ??

The truth is i don't even know if I will need 650w in the next 2-4 years but on the other hand you never know

i have a focus gx750 and gx850 thay are very good PSUs quiet with a 10 warrenty as for wattage its better to have more and dont need it than need it and dont have it so id go with the one with the most.

What about the core gm's fan ?? You think I will need to replace it after 25,000 hours or this number that gave seasonic is lower than the real ??

i carnt tell the future but i dont think seasonic would fit it with a poor fan but the core 650w dont have a quiet button i dont think which is handy to have, why not pay a bit more for a focus gx650.

Considering you plan to upgrade to a 200€ gpu, it will most likely not pull much power. Up to 150W. Therefore a 550w is more than enough. The only issue arises if you decide to upgrade to a higher tier gpu at a certain point.

I would personally pick the focus 550.

The biggest plus in gx for me is the hybrid fan mode (less dust)
First, both have fan control. The fact the GM does not support fanless mode is really of very little significance - unless this computer will be used in a high-end HTPC (home theater PC) and in a home theater environment (that is, a room designed to dampen and suppress ambient and outside noises).

If being used for other than HTPC tasks, with a good case (I like Fractal Design cases), you won't hear the fan anyway. And with a good case, even if the GM fan is spinning at its "silent mode" (slowest) speed, the amount of dust it pulls in will be negligible compared to the normal case cooling fans. If you set up your case cooling properly and have a good case, dusty incoming air will be pulled through the air filters - a good thing. So, unless you live next to a dusty rock quarry, you always keep your windows open, you have several dogs and cats shedding pillows worth of hair and dander every day, and you have a couple rugrats running around keeping all that stuff stirred up, I would not place much value on the fact one has hybrid mode and the other does not. In other words, it is good you are concerned about dust control, but in this case, those concerns are unnecessary - or at least should not be that big of a concern to be "the" deciding factor. Dust control is the responsibility of the case, not the PSU.

And please note, this is from a guy who really hates fan noise!
the fan has only 25,000 hours of life and within 5 years i will reach this number.
How did you determine that? First, the 25,000 hour rating does not mean in 25,001 hours it is going to die. Also, that is at 40°C which means that PSU would be running at "very very warm" temps the entire time. Unless folding or mining, that is not likely. Also, verify your math. To reach 25,000 hours in 5 years, that computer would have to be up and running running fairly demanding tasks (not just at idle) almost continuously 14 hours each day, 365 days per year for 5 years straight (13.7h x 365d x 5y = 25,002.5 hours). Finally, the supply has a 7 year warranty. If the fan wears out in 5 years, get a new supply for free under warranty.

That said, the Focus has a 10 year warranty.

Most people buy way more power supply than they need. 550W is probably plenty but you have not listed your total specs. So you really need to sit down and figure out, as best as possible, what your needs will be in 2 or 3 years. Don't guess. You can research each and every component to determine their maximum demands, add them up, add a little for inevitable aging to get your needed size. Then pick your supply.

Or use a good PSU calculator to do all that for you. I only use and recommend the eXtreme OuterVision PSU Calculator. This will calculate your minimum needs and recommend a suitable size for those needs.

Plug in all the hardware you think you might have in 2 or 3 years, to include extra drives, bigger or second video card, more RAM, etc.

I recommend setting CPU utilization to 100% and Computer Utilization Time to 16 hours per day. These settings will help compensate for component aging, and add a little extra padding to the results. This will also result in a little cooler and quieter operation.

Note that no calculator wants to recommend a PSU that is underpowered so they all pad the results, some more than others. The eXtreme OuterVision calculator is and can be the most conservative (my reason for using it) for 2 main reasons. (1) They have a team of researchers on staff constantly researching components for us to keep their extensive databases accurate and current. And (2), it is the most flexible and has the most extensive databases of available options you can enter. This allows it to factor in all possible components to accurately calculate our needs rather than guess.

the life expectancy of the GM fan is 25,000 hours at 40 °C, 15 % - 65 % RH (as a worst case scenario) so unless you plan on mining and/or playing video games without sleep I don't think you have anything to worry about. Considering Season places a seven year warranty on the PSU, they don't think you anything to worry about as well.

Thank you all of you for the answers and most the @Bill-Bright for that detailed post !!
1st. The pc runs on ~14 hours per day with 8-10 hours in use.
2nd. In the eXtreme OuterVision PSU Calculator shows that I need 469 watt with ryzen 2600x (95w) and rx 5700 xt (225w) and all the other components and peripherals I need and I use. I don't think I'm gonna need more powerful gpu in the future as for the watts.

Considering Season places a seven year warranty on the PSU, they don't think you anything to worry about as well.
The 40°C is the room temperature or the inside psu temperature ?? My room temp is 28-30°C in summer and 20-25°C in winter

Not sure where you're buying from, but it generally tends to be better to own non-Seasonic branded Focus units. Phanteks Amp, Antec Gold units or the Asus Strix, just to name a few. Look for one of those and you should have zero troubles with that setup. 650W should keep you accounted for a good 5 years at the very least - as long as the unit is well taken care of.

Right now the mobo temp is 33°C and in the summer maybe 36-37°C ? Something like that. I assume the mobo temp is the case temp, right ??
not sure what program you are using or mobo you have as different OEMs place the sensor in different locations. Its not exactly case temp but rather temp by the sensor as hotter parts will have slightly hotter temp by them.

Make no mistake the Sleeve Bearing fan is a cost cutting measurement by seasonic. Those stats I posted above come from the fan OEM (yate loon most likely) not seasonic so they would use worst case scenario. Seasonic themselves have tested the fan and feel comfortable with a seven year warranty on it which is why the fan specs and warranty don't match up. It would not prevent me from buying the unit but I also have no issue replacing a dead(or noisy) fan on a PSU.

That's just nuts(it's way too high). That being said, GPUs are taking more and more power. A GTX 970 peaked at 192 watts. A RTX 3070 peaks at 256 watts. I think this trend will continue, and is why I have moved my standard recommendation for a PSU from 500-550 up to 650-750, but I'd still take a good 550 unit over a mediocre 650 one.

You don't need those calculators in the first place if you can do your own math and use software such as AIDA64. A solid Seasonic 650W unit should have no troubles dealing with an RX 5700 and a 2600X. With those two, you're barely looking at pulling even a consistent 450W in the first place - granted you use a frame sync capable monitor.

They both are quality psu i would recommend the 650W it's always better to have a little bit more for future upgrades and the only real difference between them is that 650W has 54A and 7 years of warranty and the 550W has 10 years and 45A.

I agree. Sleeve bearing fans may cost less, but not all are created equal. A quality sleeve bearing fan can, and likely will easily outlast a cheap ball bearing fan. Seasonic is a reputable company. I think it safe to assume its sleeve bearing fans are well made, of much better quality than the sleeve bearing fans used in a no-name, generic budget PSU.
In the eXtreme OuterVision PSU Calculator shows that I need 469 watt with ryzen 2600x (95w) and rx 5700 xt (225w) and all the other components and peripherals
It would have been good if you included a link to the calculator's results so we could see what components were entered to get to that value.

That's just nuts(it's way too high).
"Way" too high? No its not. When I plug in values (some provided by the OP, others where I just guessed), as seen here, I get 467W. But note that includes 2 x 8GB DDR4, one SSD, one HD and one optical drive, 3 x 140mm fans, and I pushed CPU utilization to 100%.

When determining the proper PSU size, whether manually or with a calculator, you MUST assume each component will demand maximum power, all at the same time - regardless how remote a possibility that simultaneous demand might be. If it could happen (and it could), the PSU must be able to support it.

So a 500W minimum supply would be appropriate. If me, would go with a quality 550W. If I had planned to upgrade my hardware in the next year or two, I would go with 600 - 650W. But not more.

You don't need those calculators in the first place if you can do your own math and use software such as AIDA64.
:( How is AIDA64 going to help you if you have not bought and installed the hardware yet? You are right, no one absolutely needs a PSU calculator, but it is not just being able to do the math and adding up the numbers. You have to individually research the CPU, GPU, RAM, drives, fans, and more to determine what numbers to add. Sure, that is not that hard. But if you are going to do it right, and not guess, it sure can be time consuming and inconvenient. So a good calculator, like the one from OuterVision has a team of researchers doing that research for us, so we don't have to do all that time consuming research. And more importantly so we don't have to guess.

There are many other ways of calculating these things. Frankly, I'd take the wall power meter I bought from Bauhaus for what I recall to be a mere $10-20 equivalent over that eXtreme stuff. That calculator used to overestimate big time that it even became a meme between people like JonnyGuru.

The best method is a precision power meter, however most people have no need or own such device.

There are other methods as well, such as digital power supplies and even power supplies with watt meters on their back physically. All these tests are done on the Internet, a very good Seasonic should, again, have zero trouble with the aforementioned setup / setups. Just look what they consume and go from there. It really doesn't take a genius to do that.

My method of calulating psu wattage is quick math, two main things that draw the most power in your pc are gpu and cpu so take my pc for an example oc gpu at least 200w and and intel so called rated 95w cpu so quick math says my pc at max power draw uses about 350w just for fun right now i used psu calc and it showed 342W.

It's useless to use any power meter to see how many watts consums my pc at this time. I will buy the psu in 1-3 moths from now and maybe at the end of the year I will upgrade the rest. The 5700xt is just an example, maybe I will go for 5600 xt or something like that, I can't know at this time what exactly i will buy in the future. My current setup uses less than maybe 200w.

How many watts needs 1 hdd/ssd, 4 fans, 5 usb devices, 2 ram sticks and mobo itself ? More than 50 ?

There are many other ways of calculating these things. Frankly, I'd take the wall power meter...
So what? Why are you arguing this point? Does the OP have a kill-o-watt meter? And how does a kill-o-watt meter help if you have not purchased the hardware, or even selected it yet? What is the OP going to plug into that wall meter?

The best method is a precision power meter, however most people have no need or own such device.
Bullfeathers! Come on dude! You are not thinking. You have the cart in front of the horse. Again, how is a power meter going help you determine your power needs if you don't even have the computer to plug into it?

power supplies with watt meters on their back physically.
:eek:


All these tests are done on the Internet
:roll: :kookoo:

First, please show us a computer power supply that has a watt meter on its back. Then please demonstrate how to connect that power supply with a watt meter on its back to the Internet.

:( So you totally ignore the RAM, drives, and fans? No. That would be a mistake. And how is someone who doesn't already know how much a given GPU or CPU need supposed to know what values to use?

It always amazes me how some just assume everyone has the same level of experience, capability, or specific facts in their heads as they do. :rolleyes:

Well you are assuming and not reading i wrote that my pc at max draw uses 350W , of course i include in all parts of the pc in my quick math i just pointed out two most heavy one ;)
