PSU

[Gorge]

Hey guys had a quick question...

is it better to keep my PSU in its more efficient  range? I dont care about power bill. just PC componets. in the long run. My pc parts are...

GTX 1060 6GB OC 

i7-7700k

16GB RAM

hard drives and leds and lots of case fans 

(im plannning to get a GTX 1070TI in future) 

My PSU is a EVGA 850 WATT G3

Thanks!!

It shouldn't have any effect on your components other than the PSU itself. The PSU will likely last longer though.

last longer? this is if its at about 45%@ full load? (thats about what it would be at) but its way too low at idel something like 10% no jokes. is this bad? will the power be less stable t this load? of cn it damage PSU of pc cmponets?

A good PSU will not see a noticeable difference in life span, as long as you are not running it at 100% 24/7, which you're not. So get whatever PSU suits your system, and call it a day. A 650W unit is probably cheaper and will be better suited for those parts listed. PSUs operate at maximum efficiency at around 50-80%, and a 650W would be right in that range for either GPU.

@Cereal5 is correct. The increased lifespan will be due to lower temperatures in the psu. Practically negligible though. Its only 100+% that can damage them.

Power supplies are designed to a specification. They have to be within the acceptable voltage levels at all loads. Low idle load has the main problem of efficiency which doesn't really matter since its also not drawing much power.

oh ok thanks! does it hurt the componets over time with it being less stabl;e?

ok makes sence. also my pc will not be in its effecent range at idel. is this ok? like bad for anything?

Bro, no lol stop worrying so much. Every PC idles

Nope, you can run them however you like. They have had like 20 years to perfect the design as the specification was first implemented by Intel in 1995. They are designed knowing the computer will idle and use a lot of power at different times. 

The biggest reason for running the PSU in the 50-80% range really comes down to noise. At around 50% and below many power supplies can cool themselves without turning the fan on.

As long as you have a good brand (you do) you won't have any issues.

This is my PSU right now, at idle.

 

Its drawing around 140Watts and supplying around 124Watts

 

It's an 860Watt power supply. 

 

I've never seen it put out more that 450Watts
