How accurate are PSU calculators?

Recommended Posts

Posted · Original PosterOP

Hi everyone, I currently have a Sapphire Pulse 5700xt shipping my way, but I have this concern:

 

MOBO: Gaming Plus B450

CPU: Ryzen 5 2600x

CPU Cooler: Hyper 212

GPU: Zotac GTX 1060 6GB - being replaced by 5700xt

Case: Cooles Master MasterBox Lite 5 (3 intake 1 exhuast)

RAM: Corsair Vengeance 2x8 @3000Mhz

SSD1 (OS): Samsung EVO 500GB

SSD2: Kingstone SSDnow 120GB

HDD1: WD 3TB green

PSU: Thermaltake TR2 500W

 

Used a PSU calculator and it calculated this:

My current 500W PSU has worked very well with my current specs. Should I listen to the calculator? Or what will happen if I not?

The general opinion here seems to be they suck.  It’s better to have too much power than not enough so One therefore needs to assume they’re inaccurate down rather than up.  I’ve never seen that one so perhaps it’s pre inflated.

Most PSU calculators try to sell you (their) PSU's, so I think they almost always have a conflict of interest.. And usually overestimate quite generously.

PCPartPicker's power usage is somewhat alright. But it's still best to just check reviews for GPU and CPU power usage and add some more for the rest of your system and get a good unit from that.

 

For example, a quality 550W unit will be plenty for your system.

You could consider a Corsair TX550M, Corsair RM550, Be Quiet Straight Power 11 550W, BitFenix Whisper and some more. Just depends on availability and pricing locally.

Outervision: Usually overestimates, about 2x more than you'll actually use, pulls all the numbers out of their asses.

 

PCPP: Completely random. If they don't know the power draw, it assumes it's 0W. For this random build (2600, RX 580) I have loaded, it assumes that the motherboard will draw 60W (for a 65W CPU), that each stick of RAM uses 7W, and that the SSD will use 10W. Just adding other random parts, we find that a random HDD uses 20W, that a 120mm AIO uses 15W, and that each fan uses 5W, unless it's included with the case, in which case it uses no power.

 

Random.org with min 100 and max 400: Usually way more accurate than any of these, in most cases giving you a more realistic number that's closer to the actual figure.

Lets talk about the fact you're planning to run a 5700XT off a TR2.

 

seen a few pop with just a 480 so I'd replace it if I were you.


I tend to reply with memes because I lack social skills and don't know how to express myself correctly.

Ok so, PSU calculatores are not accurate. But now I am worried that maybe the TR2 is too small for my 5700XT.

 

I really don´t want my TR2 to pop, because I could just replace it and sell it.

 

Tech prices where I live are really high, but I found a Corsair Vs650 80 Plus 650w for $65.

 

I´m guessing the bottom line on this is to change my PSU?

Please do not put a PSU as crappy as a VS on a nice gaming PC

I just "built" my pc on PcPartPicker and it displayed 454W estimates Wattage. With all my periferals included.

As mentioned my @seon123, just don't use the pcpp calc

So then there is no trustworthy PSU calculator.

 

By that you mean that corsair PSU I posted is no good? Well, I´d have to check other PSUs ay my local market price. The thing is, I don´t really want to buy a new PSU unless I really need to.

 

Is there any other way to calculate or obtain power draw? I can see it in your description that your sistem draws 400W under max load. But I would not know how to compare it to mine.

Both Corsair and Thermaltake make excellent PSUs, but the VS and the TR2 are those company's worst offerings.

 

If you can't afford a decent PSU made for a gaming level PC, you should wait until you can.

You need to. PSU quality matters just as much as having enough power.

The one true way to obtain power draw is to measure it. Tomshardware does reviews and they measure system component power draw using measurement tools on the cables, you can check your CPU and GPU and use that as the most important reference because those are the most power hungry parts

What it means is that if an overclocked i7 and a titan only draw 400 watts, what PC can you build that would draw more? The titan Xp has an 8+6 pin PCIe power connector, and since that's a standard connector that uses a standard wattage, you can sort of get an idea for the power draw comparing other cards like the 5700 XT you mentioned. 

 

Also Intel consumes more power than AMD at stock

Ok then, I´ll discard that VS from my cart. I understand now, not to cheap out on PSU. The 5700XT also has 8+6 pin, and with what you say in mind, I´m guessing my system will use 400W or maybe just a little more.

 

As a matter of fact, I just checked:

 

Ryzen 5 2600x @ 4.2GHz (mine is at 4) uses 157W peak under load.

RX 5700XT at stock uses 243.39 at peak load.

 

Using a total of 400.39W only for those 2 components at peak load. I´m guessing the rest of my hardware will take up the remaining 100W, leaving me in a safe spot?

@Pablo Molina even the OP doesn’t get notified without a link? Or is it just not reliable  or something.  I’ve been omitting the name when the reply is intended for the OP

When you quote, the person quoted is pinged no matter what, you don't also need to mention and since it says who you quoted it wouldn't make much difference. I only mention to notify people who I didn't quote, or to address the OP after I quote someone else.

Ok, but if I understand right, you are suggesting I get a new 550W PSU and discard my old 500W? If that is the case, that is what I´ll do.
