Seasonic SS-1000XP or other?

post #1 of 18
Thread Starter 
After an RMA on my "Enermax Modu-87+ 800 Watt", and got all money back, I'm looking for a new replacement.

If I at least can get as much performance as the old one, it would be great. However I need a more quiet PSU. Sure the Enermax were quiet, but not quiet enough.

I've then been looking at the Seasonic SS-1000XP. Mostly because after I saw how quiet it is here

But the weird thing is, I cannot find any other review, having a similar schematic about the fan? That link I just provided, seems to be the only review I can find, that goes into detail about the noise.

My pc generates around 550w under full load. Would a 1000w PSU (such as this Seasonic) be a dumb buy, since it'll only be stressed around 50%-60% of its capacity?

The Modu 87+ is quieter than the Seasonic XP.... in fact you'll have issues finding a quieter(non passive) unit than the one you returned.

Though I'm having trouble understanding how you hear the Modu87+ 800W at <500W loads over an overclocked GTX 580.

The Seasonic SS-1000XP should be more quiet. At 550w only 600RPM.

My old Enermax Modu-87+ 800 Watt, had a fanspeed, of minimium 700RPM up to 475w. And at 550w, its around 850RPM

I have an arctic extreme on my GTX580 = 1100RPM constant.

It doesn't matter... RPM is just part of the equation, the bearing type, the number of blades, the blade geometry, the fan grill, etc impact the noise output... the Seasonic XP are quiet, the Modu87+ are even quieter...

Where are you from?... if you can get a Super Flower Golden King 550W(or the Kingwin variant) you'll hardly ever see the fan spinning with the hardware you have listed... or simply get the Super Flower Golden Silent.

But the Seasonic unit, uses like the best quaility fan avaliable for any PSU. Or at least that what review says.

An 500w PSU?
It'll be maxed out at 100% when I play games.

I've borrowed measuring gear from the biggest electric company here in Denmark. And when I did a prime95 + heaven, it cranked up to around 560w

That is AC consumption, on the Modu87+ 800W that means 500W load(while benching).. you'll always be below 450W while gaming... and it really doesn't matter, especially since you're in EU and that means 230vAC which subsequently means 92-94% efficiency on the SuperFlower Golden King.. so full passive operation at any load for your system(provided reasonable ambient temps).

Indeed it's a very high quality fan... that doesn't mean "a very quiet fan".. simply a very reliable fan, which is very important since the fan usually fails first in high quality units.

I don't know. It's all so confussing.

If I'll always be blow 450w, why still not get the Seasonic SS-1000XP? Put it in hybrid mode. And it'll be fanless up to 450w, acording to the review I listed in #1.


And how can I know, which company uses the best fan?

Fan on the Seasonic
"The PSU is cooled by a Sanyo Denki fan (San Ace 120, 9S1212F404) that is also employed in other products from Seasonic and Corsair. Seasonic claims that this model boasts a number of exclusive advantages: triple balancing of the copper axis, specially shaped blades that ensure high efficiency at minimum noise, long-lasting design with ball bearings. As a matter of fact, in our earlier reviews we noticed Sanyo Denki fans to have been individually balanced, which contributes to their low noise and long service life."

On my old Enermax
"Enhance used to be fond of special fans in its power supplies such as fans with originally shaped blades or with 4-pin connection. Somewhat unexpectedly, the MODU87+ has a 140mm fan with the exclusive Twister Bearing but without any remarkable external traits."

You're asking too many questions and looking at all the wrong reviews... for PSU reviews and silent computing you visit these guys.... and if you're strictly interested in noise output you look a dB ratings, "best fan" can mean a lot of things and noise output is just one of them.
