I'm looking for a cheap but quiet PSU, supposedly around $100-$200 CAD for both of my power consuming cards.
 

Special thanks to JelleDekkers,tmcclelland455, and Real_PhillBert for helping me choose the PSU

Quiet? RM850

[flibberdipper]

Corsair RM850 or if you want to go nuts, get one of their AXi PSU's.

[Real_PhillBert]

I will echo the good advice listed above, Corsair RM or AX(i) series.

[dragosudeki]

The XFX PSU is good I think, or maybe get the gold rated version? I have the gold rated version and its quiet. Though why are you willing to spend 700-1000 on a PSU? No PSU costs that much I think.

Seasonic 750KM

Oh shoot, no that's the whole PC's upgrade budget. o.e oops sorry

 

edit: fixed the budget P:

Fully modular is good too, thanks guys!

gtx460 SLI will consume roughly around 300w +- and adding the cpu around 140w = <450w total power use estimate. Your 850w psu is way more than enough and that XFX unit is a really good psu. If you wanna save some money,maybe downgrade a bit to a 750w.

[flibberdipper]

No problem man. Glad I could offer some help.

I was told by a user of 460 sli to go for more than 700, yes 750w is applicable, but why not 850w?

The TDP of the gtx 460 is 160w http://www.geforce.co.uk/hardware/desktop-gpus/geforce-gtx-460/specifications . You'd be fine on a 550w PSU lol (unless you have an AMD FX CPU or an i7-e). 2x 160w = 320w (at stock clocks at the very maximum), OC'ed i7 4770k is about 150w (at 4.8Ghz which is suuuuuper rare) = 470w, = 80w left for your fans, motherboard, ram, HDD/SSDs. 

 

850w is very over kill. If you want the option to sli the highest end of the high end then yeah, 850w and your good to go.

 

P.S. You'll love the Corsair RM PSU's the'yre amazing <3.

Like I've said, total power consumption under max load on both cpu on gpu would be around 450w (stock clock), which is unrealistic in everyday use,even during gaming. Realisticaly it would probably be just around <375w. You can still use that 850w however. But you can also save a little bit money and get the 750w, or even a 650w if you want to,with some headroom for OC. Bearing in mind psu tend to be most efficient around 40-70% load iinm. And you aren't going to game or do benchmark most of the time so do the math.

That'll work just fine. But I'm not a fan (no pun intended) of the RM series.

But the fan (pun intended) is quiet.

Sigh, another lost to the Corsair hive mind.

 

Go with:

 

Be Quiet! Straight Power 750 or above

Antec EarthWatts 750 or above

Seasonic K 750 or above

Cougar GX850

 

Edit: oh it's just Fermi SLi, then go with something cheap like Corsair as efficiency, low wattage operation and noise is pointless.

I couldn't really find many of them. Be quiet exists, but not the Straight Power line.

 

The seasonic K is also more expensive than the Corsair.

*does corsair not produce good quality products or something? You sound very against it*

The RM series are just mediocre, their quality is nothing compared to seasonic. http://hardocp.com/article/2013/11/13/corsair_rm750_750w_power_supply_review/9#.Uzy-G_l_uGM

You're better off with an XFX 750W http://pcpartpicker.com/part/xfx-power-supply-p1750bbefx

dolla dolla dolla sign.

however, the XFX does look very nice, and I'm getting a window case which I'll be looking down upon.

ya' see, this is why I ask you guys!

Wow people show some creativity. Every time someone makes a thread asking for a silent PSU the first few comments are people suggesting the RM Series.
