Quietest PSU for SLI

post #1 of 12
Thread Starter 
Hey guys,

I've recently upgraded to a GTX570 SLI rig. I'm running a Cooler Master 750watt PSU along with a i5 2500K. When I had 1 GPU, the PSU would hum but not so much. Now with the SLI setup, its crazy loud when playing BF3! All the other fans in the system are nowhere close to the annoyance.

Whats the best and quietest PSU I can buy for my needs?

Some Kingwin Lazer Platinum would be best, but Seasonic X750 is on sale for $120 so I'd just get that instead.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087

At typical pricing, a lot of people would still (incorrectly?) recommend Seasonic X Series, even though there is usually better pricing on something else that's as suitable or more.

I guess I shot myself in the foot, wan't able to get the X750 last week, so the price went back to $150.

I saw a X850 and X1050 on newegg for about $200, would it be worth it to just buy one of those or should I still wait for the X750 to go on sale again?

Dang that sucks! There are other great quiet psu's out there though! My Hx 650 is extremely quiet. I would also recommend the AX gold series.

Nice! Would it be safe to say that if I get a higher wattage PSU, would my noise levels be quieter? (or does it really matter on wattage?)

I was looking at the box of the AX750 and noticed that the Db levels increase with load on the PSU (more usage of wattage)

The AX750 is a nice deal for $145 (with discount code)

BUT I must know if it will be silent with 2 GTX 570s running BF3......I dont mind spending more, just want the quietest operation for gaming.

Generally that's correct, but you prob won't hear a good 750w unit w/ SLI 570's. Is your CM PSU a GX? They are known for being loud, very loud. Here are a few PSU's pretty well known for being quiet (as far as I know), any would be a good to replace a meh CM PSU with.

Rosewill Capstone 750w $110
XFX PRO750W XXX Edition $124.20. $114.20 after MIR.
XFX PRO850W XXX Edition $139.50. $119.50 after MIR.
Corsair AX750 $144.50. $124.40 after MIR.
Rosewill Lightning 800w $150
High Current Pro HCP-850 $175 Shipped. $145 after MIR.

XFX 10% off deals expire today.

Alright guys, I have three viable options:

All modular and 80+ Gold.

1) Corsair AX750 ~ $144 (newegg)

2) Seasonic X-1050 ~ $199 (newegg)

3) Cooler Master SPH 1050 ~ $155 (seller)

Anyone have experiences with these?

I'd just grab the Corsair AX750 and call it a day. I have Corsair PSU's in all 3 of my rigs around the house and never have they caused any problems. Noise is not a problem either thumb.gif
