a little bit out of topic but what types of bearing are the best?rifle,hydro,fluid,ball which one is best to worst? also i heard some types of bearing shouldnt be placed facing down (using as top exhaust) is that true?

Yes. More resistance, more voltage drop.

 

Shit extensions are fire hazards. Decent ones should be safe, but may cause your system to become unstable.

 

Don't use extensions. If you want funky cables, buy a full modular PSU and custom cables.

how do i know its good or bad? its a diy created by the seller and it has 18 AWG thicknes

if you have the right ones, not really afaik

and what makes one right and one isnt?

does psu sleeved extension effect anything?

btw what should i check after buying used psu?

The warranty is not transferrable. You will get no warranty. The HX Platinum is better than the RMx, but if the options are a used HX vs a new RMx, get the RMx.

how do the distributor even know im not the 1st hand anyway?

the distributor it self said the only requirement for claiming waranty is the sticker.

i can get an hx750 used for 60$ with warranty until 2027, is it worth to get used psu like this? even brand new cx550m cost 77$ here

btw corsair hx vs rmx which one better?

anyway after some debating with my friend (EA550G vs pp11)he ended up with this answer

"I still don't recommend using pp11. pp11 topology is still active clamp reset forward, which is only a modification of the single forward topology. efficiency has increased dramatically, but the transient response is still weaker than resonant-HB LLC, especially the resonant LLC-FB
so the two will be messed up. seasonic focus due to aggressive protection settings, FSP raider because of design

but the problems in seasonic can be overcome by the manufacturer with a little tweaking.
on fsp? can't do it. must replace the new platform"

What are you trying to power? the EA550G is actually worse if you use a GPU with high wattage spikes like the Vega56 and can trigger issues.

 

I'd go PP11 personally, it's quieter as well.

i showed your answer to my friend that recomended ea550g and he said this

"if you use vega56, I still don't recommend using pp11. pp11 topology is still active clamp reset forward, which is only a modification of the single forward topology. efficiency has increased dramatically, but the transient response is still weaker than resonant-HB LLC, especially the resonant LLC-FB

rx 580.

i think im going to buy pp11 anyway because its cheaper and most people in LTT recommend it

pp11 500w vs EA550G pro (seasonic).

 

which one is better? im about to buy the pp11 but my friend told me that pp11 are just tweaked pp10 which is not worth it, is it true?

pp11 500w vs EA550G pro (seasonic).

ok seems like everyone favor pp11. the non CM version are equally as good right? 

im on south east asia. corsair stuff are very expensive here.

anyway what about antec EA550G (oem from seasonic focus gold) for 82$ or whisper m 550w for 92$

my system is i5 6600k + rx 580. probably upgrade to ryzen 7 3000 series when available.

which one is most worth it?

1.used evga 850GQ for 65$

2.bequeit pure power 11 500w for 76$

3.leadex silver 550w for 71$

4.evga 450gd for 53$

5.cougar gx s 550w for 72$

i planned to get the used 850GQ but i saw amazon reviews and it has lot negative review. some people fried their fans and fan hub because of that psu. also some people had popping caps etc 

evga gq and gd whats the difference other than modularity? because i can get a used 850GQ for 10$ more than new 450GD

it's a dual forward, whines on anything 1070+ and older revisions used a sleeve bearing fan

does evga 450 gd does that too? because i never bothered by a loud fan. but im suffered when theres an old phone charger plugged in next room because i can hear the very high pitched noise while others mostly wont notice.

the fan rated at 33db, how loud is it?

If you don't care about noise (like I, and I think most people), go for the GD.

but thats didnt mean GD is noisy right?

evga 450gd cost 53$

whisper bwg550m cost 92$

is it worth to get the whisper instead of evga? what does make whisper much more expensive other than wattage and modularity?

anyway i got a question from my friend

cougar vte any thoughts? what tier is it?

https://cougargaming.com/us/products/psus/vte/

its dc-dc and has a pretty strong single rail 12v. its cost 40$ for 400w which is pretty cheap

I thought the 2700x system was paired with an RTX 2060 (around 160W)?
The i5 6600K (stock) is like 70W so if that is paired with the RX580 then yeah, still around the same as a 2700x paired with an RTX2060.
"Worst case" scenario of the 2700x + RX580 will use a little more power, but you'd still be well within the limits of a 450W PSU.
I have an i7 6700k and GTX 1080Ti and I have to go pretty heavy on the overclock to exceed 450W.

Either way you answered your own question. Also real world gaming power consumption will be a little less than the power consumption figures for synthetic power tests. Regardless, decent PSUs should have no issue outputting 100% of the power 24/7.

 

They never said anything about any efficiency curve... ?

yes i mean 2700x and rx 580 are worst case scenario.

"decent PSUs should have no issue outputting 100% of the power 24/7."

so even rtx 2080 + i9 9900k which consume about 420ish watt should be fine for evga 450GD?

Yeah... RTX 2060 going to consume less power than the RX 580 anyway. 2700x would consume little more than the 6600k, but in the end it'll all balance out really.

All up probably looking at ~300W peak power for either system with a little OC.

2700x=105w

rx 580 oc'ed=235w

5fan and 2 hdd = 40w

total=380w , which means it give 85% load at the psu, it is fine for the long term?

1 minute ago, Spotty said:

That'll be fine. 450W is plenty for that system.

if i upgrade to something like 2700x + rtx 2060 it should still has some room for oc right?

a bit louder, worse fan, other oem

 

but still decent enough to consider

evga 450gd for a i5 6600k and rx 580 is it fine or should i go higher watts?
