Right PSU?

[muttsang]

Hi guys,

 

I am building my first Game Dev Workstation and here are the specs of what i am going to build.

Pc part picker shows it will use 434w in total (keyboard, mouse and monitor not included). But when I calculate with https://outervision.com/power-supply-calculator this website. It shows around 461 w required (keyboard, mouse and monitor included).

 

I have already bought 550w psu link => https://www.ebuyer.com/782056-corsair-tx550m-550w-80-plus-gold-power-supply-cp-9020133-uk .

I think it is just "okay" but i don't want to run my psu around at 90% . I saw some videos that said that heavy load on the psu decreases it's lifetime sometimes damaging the parts.
Should i return the 550w psu and get a new 650w or 700w psu? or is 550w enough?

 

Thanks,

muttsang

A 1080 Ti and 2700X would be fine on a 550W unit. You're totally fine, don't worry about it.

550/650 watt PSU that is Gold rated.

 

Something like the seasonic Focus Gold 550/650 watt

 

It is not often the PC will run at full combined load. Even then the Rated wattage is a bit on the safe side of things

I have got a 550w 80+ gold corsair . So i guess that should be enough right? 

Thanks for clarifying that the rated wattage is a bit exaggerated by the website itself.

PSU calculators are useless and overestimate by a ton. With a Ryzen and a 1070 Ti, you're looking at closer to 300W under full load. 

PSUs are rated to run at a 100% load 24/7 at their max rated temperature for the entirety of their warranty. "Degrading" over time isn't really an issue. Whoever said you should avoid running a PSU at close to 100% load should really be avoided, as you don't know what other crap they can drag up from their rear end.

It is a bit exagurated, but i would not go below it in terms of PSU selection.

Anything 550+ and Gold rated is good for most things today

Sorry for the late reply. 
And thanks for clarifying that! I posted the same thing in reddit and the people were commenting about not to use the psu at around 80-90% so I was terrified about that.

Can you also tell me if the psu was to somehow stop working, will it harm my components?

Reddit users are idiots.

 

If a PSU is rated at continuous output, not peak, at 50°C, such as the TX-M, then you can run it at ONE HUNDRED PERCENT LOAD ONE HUNDRED PERCENT OF THE TIME.

 

You're fine.

Of course there's no 100% guaranteed safe dying of PSU.

But properly designed and built PSUs mostly fail harmlessly.

 

Anyway that PSU certainly won't be dying from too much load.

With 1070 Ti's power consumption and what 2700X draws under full load max power draw would be around 350W.

But games don't cause full 8C/16T load, so actual gaming power draw will be around that 300W.

No.  I will.  I can't go there without feeling the deep depression that I coexist on the same planet as some (probably most) of the people that post there.

I see rather often some people pretty much claiming "PSU is going to explode soon if loaded over 50%" also in forums where people should know better.

Well, if it's a Linkworld, Deer, Codegen, etc.... That may very well be true!!!

They just say same even about known top quality thoroughly reviewed PSUs.

And use that as justification to buy totally oversized PSUs usually with lower quality components. (to keep price affordable)

Like 1kW PSU in PC having pretty absolutely highest possible load barely 350W.

The Problem with PSU is that people still parrot the Fairy Tales from 20 Years ago, when the PSU Quality really wasn't that great, the Efficiency was in the Toilet and usually something in the 60s with 72% Peak...

 

And because that wasn't wrong 20 Years ago, it has to apply today, 20 years later, when most active components have nothing to do with what was common then.

A MOSFET is something totally different from a Power Tranny or a Diode but that's what PSU use today...

 

And the Efficiency "curve" is way flatter than it was in the olden days.

Today we usually have something like 2% Difference between peak point and 80% and that is close to the worst case you can find these days. In 230VAC Countrys its usually a bit less and the Efficiency  a bit higher...

 

And that's the red thread through everything.

Beliefs over facts....

 

Well, if it's a Linkworld, Deer, Codegen, etc.... That may very well be true!!! 

 

And that shit might be what got this fairy tale startet...
