High quality quiet PSU )modilar, semi-modular)?

[alexsan]

Hello all,

I'm looking for a high quality PSU.
I have heard that Corsair and Seasonic is very good and I hope you guys can help me pick a good one.

I want one that is silent provides at least 750w power and has high afficiency. I guess I need a modular PSU with fans that only spin at certain load?

What do you guys recommend?

Corsair RM750 seems pretty good for the price, if you want even better efficiency go for a Corsair or Seasonic 80+ Platinum unit.

I've got a SeaSonic G-550 that I love, completely silent and with gold efficiency. It comes in a 750W variant as well, which is worth looking into if you require that kind of wattage.
It is pretty pricey in terms of watt/$, but if it lasts 4-5 years, price is hardly going to be an issue.

Noob question but :'( ... does modular means that the fans only spins up at high usage or does it have to do with power the cables so you only connect what is needed?

I want both as I am looking for silence. I also need long power cables.

It means the cables are detachable / attachable.

What case, and what case fans are in use? What graphics card (cards?), motherboard, CPU cooling?

Be careful with the Seasonic OEM models as those aren't particularly quiet.

What are you powering that requires a 750W PSU?

A Seasonic X-650 will power just about any system with a single video card, is 80Plus certified, modular cables, and a fan that only needs to spin up above 300W.

Any high quality 650W unit will power any single GPU setup (and many dual GPU ones). The X-650 is not an exception, though a nice unit it is. It's also not just 80Plus, it's 80Plus Gold (which is not unusual these days).

Indeed they will. He asked for a quiet one, and mentioned Seasonic by name. Can't get much quieter than a unit that doesn't spin its fan until heavily loaded.

Based on what you have said, the Seasonic 760 Plat is the one to get. I have it and I love it. It is running my two 760s in SLI without a hiccup.

$35 off plus a $20 rebate = $109.99

It has hybrid fan control so the fans won't spin until you get to 50% load, but even on normal the fan is inaudible.

The seasonic x-650w is a great PSU (own one myself).

The fan at low draws can turn itself off and the cables are modular for a nice clean build. I did try the corsair 750W psu mentioned above; i found it a little to loud for me at low draws. the fan doesn't turn itself off and just had a bit of a weird hum to it.

Thanks for all the replies guys.

In my long journey searching for cool but a relative silent case I kind off pinned it down to the Corsair 750d.
I like the design and revies shows reasonable levels on both thermals and noise.
I like to fully use cable management for a clean build so PSU cables have to be long enough to route behind the motherboard.

I will be running a single GTX770 to start with but possibly upgrade to second one if I need it.
(I use a Dell 27 inch and like to game game on 2560 x 1440 with decent video settings)
Rest of my setup will be a Asus Hero, 4770K, 8GB corsair vengeance LP. 2 x SSD and 2 X HHD for large data.
I will be air cooling with a Noctua NH-D14 and assume the provided fans of the Corsair 750d will do the job.

I dont necesarely looking for a PSU that just fits in terms of power, a little overhead would be great.

750W is good for dual 770's.


Just checking , you're in the U.S. correct?

Best PSUs are Enermax. I Imagine they will go bust soon for the opposite reasons to OCZ and soon XFX. Making the best rules.

 

[lehtv]

Enermax aren't the best, actually. Seasonic, Super Flower, Delta, Flextronics... they're all better

Agreed, Seasonic, SF, Delta and some Flextronics units are better. Enermax though does make good PSU's just not in the top tier anymore.
