Replacement for Leadex II with quiet fan

[Billy_Wellington]

Hello, what would be a good replacement for Leadex II 750w gold unit, with more adequate fan control?

My problem with leadex is that, with standart mode - it's fan is louder than any other fan in my system and eco mode is behaving inadequately, randomly spinning the fan to crazy high RPM's even when PC is idle.

Something fully modular, with very low RPM at idle or ECO mode that actually works? Thank you.

What are you powering, what's your budget, and where are you buying from?

Sorry, for now it's 1080ti, and 6700k 4.5 ghz overclock. If i am upgrading it will be something like next nvidia xx80 card and any of the amd\intel 8 core 16 threads mainstream cpu's I do not have hard drives, i have only m2 ssd's for storage and really not much else to consume power.  As for the budget, i would not want to go above 150 euro.

I live in Moscow, Russia and choice of PSU's here might be limited and many models will be overpriced, but i can order from amazon us or check european stores as well. Just need a few models to start with. And ofcourse i will also check locally and compare the prices. I could probably sell leadex ii here as well.

PS: Just looking some of the stores i used, there is Tier A  fractal design ion+ units.

860p platinum is only 5 euro more expensive than 760p unit and with delivery this will go for 143 euros.

At the very least there is a zero rpm mode, is it a good one?

it's fx based, but with a 109% opp

Oh ... I don't think it really qualifies for tier A then, tier B+ with a note maybe ? Because people getting high-end unit expect it to be, um, high-end and 110% doesn't exactly qualify for that, might trip on transients with some very power hungry setups with load levels close to 100%.

Enermax Revolution \ Deepcool DQ-M \ be quiet! Straight Power 11 - same platform. Or Corsair RMx. All of them are very quiet units (up-to ~400W load), go with cheapest one (Deepcool one goes for 6k RUR with promo code). There's also somewhat cheaper Aerocool P7 but i'm not sure how good it is despite it uses the same platform as those three units above too, there are numerous user reviews of it citing issues with fan controller \ overheating \ reboots. @LukeSavenije can you dig on this further ? Maybe it should be detiered ?

Deepcool DQ-M

I found a review, looks like it starts spinning at 600 rpm, kind of like the fan on Leadex II which i can definitely hear. Maybe i am too sensitive with noise, but i would avoid this if  possible since all my other fans idling at 300 rpm.

Better, start RPM is around 300, but 750w model out of stock and 850w is a solid price bump. International shipment is an option.

Also an option.

 Corsair RMx

This one does seem to have 0 rpm up to 40% load, which is great. That is for "2018" model, there is also "2019" is there a difference?

 

But in any case, is there a reason not to buy the Fractal Design ion+ PSU i've mentioned before? There is also zero RPM up to 40% load

 

Thank you.

2019 are RM, it's completely different platform and it's not very quiet, basically somewhat renewed TXm.

Look at the prices mainly, get the cheapest, i didn't see FD Ion+ on Yandex so i'm not sure how it compares to other units price wise but it's almost as quiet as be quiet! E11.

RM isn't even a greatwall though... i'd rather call it a downgraded RMx here

 

but for what's important here, the RM has an issue where it starts to make a high-pitched sound when switching between powerstates (~90w), which might be a problem for @Billy_Wellington

I mean, not platform wise but rather overall performance wise.

I also check computeruniverse german store, because usually their price + delivery equals the price in Moscow.

Almost everything you mention is there.

be quiet! Straight Power 11 750 Watt - 102 euro

Enermax Revolution D.F. 80+ Gold 750 Watt - 93 euro

Corsair RM750X (2018) 750 Watt - 98 euro

Fractal Design ION+ 860P 860 Watt - 110 euro, but it is platinum and have more wattage, 760p is only 5 euro less.

The delivery will be about 30 euro.

What you're powering anyway ? Chances are you don't need more than 650W PSU even if it's smth like i9 9900K + RTX 2080 Ti even from the load level to noise perspective since it'll hardly consume more than 300W in gaming. If it's workstation build then yeah, going for higher wattage might reduce noise output.

I currently have 750w unit, before that i had 550w unit (xfx xtr) and when i switched from gtx1070 to 1080ti it's PSU fan was working at full RPM, so i bought 750w unit to deal with this, 550w was not enough apparently or just it's fan controller went nuts. I am guessing it wouldnt make much sense to buy less watts than what i have now, but maybe i am wrong. The CPU is 6700k, as i mentioned before.

There will be some upgrades, but i guess new hardware is suppose to be more efficient, so yeah maybe i will be ok with 650w, but i'd rather be safe than sorry.

Every unit has fan curve configured differently, it's not only about power, if you look at Cybenetics noise output to load graphs you'll see that with ~300-400W of load, already quiet 650W and 850W units will have the same noise output.

So, if you were me, how much wattage would you get? 650w? For 6700k and 1080ti

Say if i am upgrading, in theory it will be Nvidia xx80 card and 8 core 16 thread cpu from either intel or amd, do you think 650w would be fine?

Even 550W are enough for any single-GPU non-workstation build from power draw perspective, but if you're concerned about noise, say OC'd 9900k + RTX2080 Ti consume about 400W in gaming (whole system), 650W+ versions of Corsair RMx (both 2015 and 2018), be quiet E11 and FD ION+ should be on the same noise output level with this load, Enermax DF and DQ-M may be just a bit more noisy but we're talking about 5 dBa difference, you wouldn't notice that. My recommendation is still same, any 650W+ unit of those i've mentioned, 750\850W versions if it's <10 EUR more, be quiet! E11 or Corsair RMx if they're <10 EUR more as they're slightly quieter than others.

Choosing from those options you've mentioned, i'd get be quiet! E11 750W.

Yup... 650W is enough for any mainstream system with a single GPU you can currently put together.

Alright, thank you guys. I will pick something from those models.

[Billy_Wellington]

One thing i forgot to mention, for semi-passive PSU's such as RMx and ION+ would the temperature be an issue?

I have fairly standart modern case, NZXT H700, PSU is placed at the bottom with fan facing down with a gap between table and a fan for intake.

I guess this will have to be corsair or fractal then.

The DQ-M has Deepcool's own fan in it. I happen to know they are very good quality and quiet-running fans. used to have 7 of them in my rig a few years back. So I wouldn't compare the fan to that of other units, they will be different.

 

I am planning to buy a DQ650M for my new build. Will report back on how loud or quiet it is.

Even good fans are audible at 600 rpm, the PC is just a few cm away from my right ear. I have phanteks fans for intake and they are audible when they reach 500-600 rpm, noiseblocker eloop that i have for exhaust is also silent up to 400 rpm, but not more. I cant see the reason deepcool will be any different.

 no not all of them are audible you can check the noise rating from cybenetics lab

Also by the looking at Super Flower units, with leadex iii it's crazy fan speed seems to be resolved xd

Because they are different fans with different blade and frame designs.

 

You can see in the image here, this is Deepcool's own unique fan, which you won't find in other brand units based on the same platform.

 

[Billy_Wellington]

Also in what cases "high inrush current" can actually cause problems?

I still decide between corsair RMx and Fractal Design Ion+. The reviews mention the inrush current of Ion+ units is much higher than other units and say it might cause some problems, meaning if my apartment have crappy power lines, weak circuit breaker and such?
