new power supply calculator

[AsRock]

There is already a note mentioning the upgrade thingy and PSU cooling if choosing a higher wattage PSU. Maybe it should be written more clearly...
I'll be adding more hardware in the next release. Will check those drives too then.
Good to hear the load result is in the ball park. Usually calculated load power is a bit higher than measured one since it's rare to have all the hardware working at a same time (all drives reading and writing + all cpus and gpus working etc).

Since weekend is coming, next release will be in the next week

So true and the my max while gaming is about 280w although typically 210-230w, but as seen as there is programs out there to push the hardware it's better to have it's usage.

Maybe to say max usages are appox when using some thing like OCCT and note that gaming is more likely not to hit those numbers.

This is pretty good. You're off by 20 watts on my calc compared to a popular PSU rating site. It might be that I had to choose Seagate 1tb HDD when you don't have the list with Constellation Enterprise 1tb in it.

This week my cisco router broke and it created all kinds of problems so been a little busy but managed to get a new version out with little improvements.
Added over 100 new hard drives and ssd drives and also 200mm fan. Maybe next thing is to add overclocking.

Congrats on improving an already fine program!

dang even on that one the X4 760K is not referenced ... my older PSU calc i used was http://extreme.outervision.com/psucalculatorlite.jsp who also don't have the X4 760K in the listing

Idle power: 84 W
Idle power is the power drawn by the system when booted to a desktop while the computer is doing nothing at the given moment. Please note that idle power may be lower when computer screen is turned off or system is in deep sleep. Also if you have disabled any power saving features of the system, the result may vary. Idle power does not include power losses from the PSU itself.

Load power: 278 W
Load power is the average power drawn by the system when running an intense 3D-game with all CPU-cores, drives and peripherals operating at maximum load. Load power is the maximum power the system may use in a typical real-world scenario. Please note that load power is not the absolute maximum power of the system. By running a synthetic benchmark, power consumption may increase even further. Load power does not include power losses from the PSU itself.

Recommended power supply: 371 W
This is the minumum recommended PSU wattage for the selected components. Choosing a lower wattage PSU increases the risk of system to become unstable and noise from PSU to become annoying. Choosing a higher wattage PSU decreases efficiency at lighter loads, but leaves a margin for overclocking and future upgrades and also ensures the PSU stays cool and quiet.

kinda what i got with the other one (using a A10-6800K for ref instead of the X4 760K)

 

[Kaynar]

Would love to see a "mild OC" and "heavy OC" options for CPU and GPU separately, maybe a slightly larger HDD and CPU database (my older i7 930 is not listed, hey its not ancient yet!)

 

[Shou Miko]

nice site, i will use it in the future, i hope there will be adding a overclocking feature as asked before, keep up the good work ElectroZ

 

[silentbogo]

Good job! Thanks man!!!
Even though some hardware is not on the list, it still gives a nice approximation for almost any system.

if he add the same OC template as the site i linked previously, then it would pretty much be my official PSU calculator

Good job! Thanks man!!!

yep just like i have to do my calculation with a A10 6800K instead of a Athlon X4 760K but even the others i tried don't have the Richland Athlon (tho they have the Trinity/Llano and i doubt the consumption of the highest Richland is too much different than the Trinity/Llano one)

 

[repman244]

Add the X6 Phenoms, there are many floating around

 

[ElectroZ]

Prayers has been answered yet again!

PowerSupplyCalculator now supports overclocking (or underclocking/volting) of the CPU and the results seems to correlate real world results quite well
Also over 200 older CPU's has been added including those X6 phenoms.

Enjoy

ok im right on it feedback a bit later

"Recommended power supply: 504 W
This is the minumum recommended PSU wattage for the selected components. Choosing a lower wattage PSU increases the risk of system to become unstable and noise from PSU to become annoying. Choosing a higher wattage PSU decreases efficiency at lighter loads, but leaves a margin for overclocking and future upgrades and also ensures the PSU stays cool and quiet.

NOTICE: We didn't find the real SLI / CF result for the selected GPU configuration. GPU power is calculated without the link."

the last part bug me a bit (other than i still have to do my calculation with a A10-6800K)
but its 30w under my other PSU calculator

according to the other one i would be 5W above my 530W PSU in a R9 270 CFX scenario

The notice text comes every time when the database is missing the real (measured) power consumption of the selected video card in SLI/CF configuration. And that's simply because I don't have all the multigpu-results of the cards.
There are now 393 video cards in the database. Lets assume that 30% of them supports bridging up to 4 cards together. That's about 120 cards and each card holds 8 measured values (4 idle and 4 load). That's 960 results I would have to hunt down from somewhere to fix this error No time for that and all of the results can't be found anyhow.
Instead, when multigpu result is not found, the power consumption of a single card is just multiplied with the card count so it might be a bit higher than the real consumption.
Currently 108 cards have at least the dual configuration result so that's quite decent for the time being.

the cpu selector is buggy [does adapt itself to the number of cpu] and have not a lot of xeon
for 206 w you advise 266 : so psu is at 80%....while it is best between 40 and 60 % [50% and writing it]
https://www.google.fr/search?q=psu+...gIKya1AWtvYDwBg&ved=0CDEQsAQ&biw=1270&bih=385

may be , the advice for ups power in va could be added [125 % of psu ]

Can you clarify how its buggy? The CPU count is the number of physical processors on the system (so typically should remain 1 unless using a server board). It should add up to the result is it's working correctly. The recommended PSU is the minimum recommendation, not what you should actually buy. I believe most of us don't have system running at maximum power all the time so it's ok to utilize 80% of the available power at load, but that's my opinion as a PSU designer

I should probably clarify the recommended PSU text a bit next

ps. I'm referring to those PSU's that actually delivers what they promises. If you purchase a cheap-ass chinese PSU then 50% more would be recommended since they do not give out the output they are labeled for.

 

[jcgeny]

if i select two cpu , then list should shows compatible cpus like opteron 4000 or xeon 5500 but not i3 or i5 ..
80% of power is the max delivery for a psu or why they would check efficiency at this level and with first psu : being happy to loose only 20% of energy .

for myself i have bought 3 psu last year : all 80 platinium ; 4 years ago 2 80 silver...
efficiency is now very important and good psu are made , each generation better than previous

Seriously, this is not a problem... Please.

Brother you've done really well with this congrats I did a little calculating for my machine and the PSU that was recommended is smaller than what I use and max draw seems just about right

Hi there,

For the past few weeks, I've been working in a new PC wattage calculator project and the first version is finally released at powersupplycalculator.net

I know there are already half a dozen similar calculators out there but they rarely work like expected (or at all) or they just give you an rough estimate of the recommended wattage without anything really to support it.
This calculator on the other hands tells you the actual idle and the load power consumption of the selected parts so you can have a better view of the true power usage of the system.

Try it and post comments here so I can improve it. I know its still missing some vital parts like PhysX cards and water pumps but they will be added later.

I tried it out, and I like it overall, the setup is nice, but you don't have the Athlon X4 750k (Trinity), Athlon X4 760k (Richland), Athlon X2 370k (Richland), Athlon X4 740 (Trinity), or Athlon X2 340 (Trinity).

I personally run an Athlon X4 760k and I was sad to not see it in the list, so I had to use the APU variant which I do believe is the 6800k, I might be wrong. So just a heads up on more CPUs for you to add. otherwise it's all looking good

 

[Aquinus]

Not too bad on the calculation. It says my idle should be 150 watts when I actually get more like 200 even when pulling the offset negative like I am now. However loaded power is realistic when the machine is fully OC'ed (568 watts). So at least in my case it appears the idle was undershot by 50 watts and load was overshot by about 100 watts given the data I put in.

 

[kn00tcn]

really liking this one, tried it on my old desktop & recent apu, although i dont have a way to read my personal wattage, it sounds about right from what i've read

there's also the obligatory...

Idle power: 1083 W
Load power: 7008 W
Recommended power supply: 9476 W

TO THE MAXXXXXX

(well, attempted max)

 

[Fierce]

Maybe I overlooked but (my) i5-4460 is missing, and what about the 860K?
Rest looks pretty solid to me, good job.

 

[JunkBear]

Idle 75w Load 198w Recommended 256w Man that's a cheap psu demand. Basically I can fit any psu and it will work.

I have my i5 paired with a Seasonic 520 watt,i wil do an 860k build next week that has a Corsair VS450 in it.

 

[PLAfiller]

I just tried it today, pretty awesome. I am trying to figure out the PSU for my next mini ITX build. The case only accepts flex ATX and I have access to 220W and 270W. It depends a lot on which CPU I get my hands on. If I run i3- then 220W is plenty, if I save up for i5, then 270 would be the way to go. Anyway, may be you should add button "Donate" and link it to your Paypal account.
