Silent Power Supplies?

[Guest]

Hi, I'm looking for a silent power supply. I asked Corsair what their best one was - the AX1500i but then I heard a review of it when it first kicks on it goes up 100% fan speed and it's some what loud for me. So... any other good ones? 

[Oshino Shinobu]

EVGA's G2 P2 and T2 series all have a 0RPM mode, very good PSUs.

 

EDIT: All PSUs will a 0RPM mode will turn on the fan at a certain load. The larger the wattage, the later it turns on normally.

I have a EVGA g2 750 watt gold. It has a eco mode, and The rest of my system is dead silent and I have yet to hear it kick on(I know its zero RPM on idle)

Seasonic has passively cooled PSU's, but they're expensive.

Seasonic has PSUs that are completely silent, no fan at all. However they're quite expensive. 

 

For a PSU that has "hybrid" or "Eco" fan mode where the fan only turns on after a certain load or temperature... don't bother with Corsair. They heavily market this feature and as a result their PSUs are overpriced.

 

550W-650W get the XFX XTR

750W and above, get the EVGA G2.

Looking at a Corsair RM series right now, but I will for sure have a look into the Seasonic ones

Please, don't even bother with the Corsair RM series. You pay way too much and get a subpar product that barely outperforms the CX. Same with pretty much anything Corsair past 50 bucks or so.

As mentioned above the XTR and G2 are much better options then the RM.

OP, just in case it hasn't been mentioned yet, Seasonic has passively cooler PSUs but they are expensive.

Also, I have an RM750. It works as advertised but I keep getting weird notifications about voltage fluctuation on all rails. Now, in HW it doesn't show any change, only on AI Suite II however this didn't happen with my older PSU.

Just to be clear, which ones offered by Seasonic are completely silent?

My RM750 is quite quiet, I have never heard it. I rmaed the g2 for being noisy, but the rm is perfect.

About it. Yes, it is expensive compared to what you get, but it wont kill your system, and it stays quiet. I believe they updated it, so the newer rm750 are actually of slightly better build quality compared to the same psu at launch.

[Guest]

you could buy a big wattage psu that runs at 0rpm if it doesn't hit it's load, that would be the best way to go (a bit expensive though xp)

how many watts

[Guest]

Okay so my choice for now is going to be this snow silent seasonic 1050W, but is 1050W enough?

Enough for what ?

Mine is 750 watts, butbI believe they go up to 1000 or something

It doesn't turn off with load, it turns on based on temperature, once the unit hits 45c I believe.

 

I put a 900w load on my 1000 P2 awhile back with my x79 system, and it took like 35mins to turn the fan on. Was pretty awesome

my system, it's coming along so far as running for most of the power as a titan X (maybe), 4 SSDs, 2 hard drives, a RAID controller/card, keybaord and mouse, speakers, intel core i7 4790K, not sure what else I might have that could really consume a ton of power, I used this PSU calculator http://extreme.outervision.com/psucalculatorlite.jsp(not sure if it's a good/decent one to use) and it said only about 700W so I figure the PSU I looked at should do it right? Or am I missing something?

Ah, maybe it's the Corsair ones that are based on load then. I know some of them are

As far as I know, only EVGA is based off temperature, which in my opinion is the best way by far to control the fan. And superflower I believe, since they're the ones that oem those units.

Yeah, it definitely makes sense to do it by temperature. Planning on a 1000W P2 for my next PSU (:

The only problem I have with it is that it doesn't have nicer looking stock cables.

 

I got custom cables though, so it doesn't really matter.

Ah, I'll be sleeving them myself anyway. Or maybe go with CableMod if I can't be bothered to do a whole PSU again
