coolermaster silent pro 1200w or corsair ax850?

Rofflay · 30 Mar 2011 at 07:40

So now the coolermaster is cheaper £130 online and the corsair ax850 is £150 which would you choose? single card gaming only BUT it has to last 4 years so i will want to drop in the latest and greatest and still have some amps left on my single 12v rail.

The only downsides i see is the naff yellow color scheme on the silent pro 1200 and the fact it may be a more little noisy than the ax850w? Reviews said it can hit 35dba.

My old OCZ 600w is a hoover and i dont want to mess this up so i swore i would go for corsair and quality but 1200w for £130? :confused:

It will be powering a GTX 580 to start with and a 2500k at 4.5GHZ.

First of, what hardware are you packing?

Review of the Coolermaster...

...and a review of the Corsair...

Seems the Coolermaster is a good PSU but has a lot of 'ripple', the Corsair seems top quality all round. I guess it depends on if you need the extra power from the Coolermaster.

I've just fitted the Corsair AX850 last night and would recommend it so far. The cables are all nicely braided and the fan on the power supply is very quiet.

I'm using it to power a single 580GTX and no problems so far. I think 850watt is more than enough for most users and the Corsair is very efficient producing power so will run cooler also.

I would suggest getting the Coolermaster Silent Pro GOLD 1000w

Cheers for the links and feedback ill have to sit down and re read all the reviews i guess.the hardware i will be packing (few bits still on pre order) is a 2500k and a GTX 580 and a vertex 3 SSD P8P67 pro and 4GB of the ripjawx c7 ram all packed into a HAF 912plus with 2x apaches blacks and the stock 200mm fans as well so its going to be a little beast

I plan to overclock this as much as possible and im hoping for 4.5 and the 580 at 950mhz core.Thats a pretty wicked setup if you hate microstutter infact its the best of the best almost ! yes im glancing at you mr gulftown

My reason for getting the 1200w was i wanted something thats going to power any single card up until i would guess 2013-2014 until i upgrade again.I am saving also for the U2711 2560x1440 monitor so i reckon at that res the cpu can last and i can just throw in a new GFX card everytime NV do a refresh and if another 480 lightning card type beast ever was top dog in the future market i want to be able to put one in even if it takes 2x8 pin and a 6 pin.

Someone somewhere said his corsair 850w struggled with a msi GTX480 lightning :confused:

thats 70A !

The only reason i wanted corsair was noise/reputation they have but now i cant decide ! :<

PS i dont think i would consider the silent pro 1000w as i would rather just get the 1200w or a corsair i think they are the only 2 psu's out there atm that are grabbing the attention in my price bracket £150.

well i have no choice now as i went to buy the coolermaster this morning and thier pretty much all gone/discontinued in the uk.

at one point it was £130 im such a fool

oh well the yellow wires were fugly as hell.i just hope the trend continues away from high power as if i need more than 70A in the next 3 yrs im gonna cry!

only way it would struggle is if one or other was faulty

850W is plenty of power for any single card
the 850 corsair would be able to run SLI 480

i doubt cards are going to increase in power usage by a lot tbh
850 would be plenty for any single card, even in 4 years time

Running an HX850w with sli'd 470's here, system in sig draws 530w ono when gaming, furmark will push it to 740w ono.

Cards before 2015 won't be pushing a 850W psu, in sli/xfire, sure possible, but single card setups are just not going to. The general gaming load I'd say for the computer you are building heavily overclocked would be, 450W, max, probably closer to 350W in most situations.

But the question is, will you ever go dual gpu. Corsair/seasonics are silent to 20% load, incredibly quiet to 50% load but at 80% load + they do get pretty loud. While a 1200W Coolermaster also gets loud at 80% plus load on a Corsair that would mean it starts getting loud at a circa 680W load and a 960W load on the Coolermaster.

For all the psu reviews I read, I have no clue if ripple remotely effects long term stability or anything but LN2 overclocking, why, beceause the review sites tha tpride themselves on how massively brilliant electronically the PSU's are, do no real world testing nor suggest what bad ripple means to the end user, nothing, or another pointless "benchmark" that means nothing, I honestly don't know.

Corsairs are great units, is it worth spending that much, probably not, whats the quietest psu around, god knows, you really have to buy every psu around yourself, get enough gpu's to load it up and see for yourself.

In reality theres going to be very few situations a 1200W coolermaster is either louder, or less capable than a 850W corsair and a lot of situations the 1200W can handle that the 850W won't be capable of.

Considering the coolermaster is around £110-120 and the Corsair 850W is what, £150-160 I really wouldn't bother.

Thinking about what i said about the lighting pushing 70A yes something there was faulty as i have this graph now.

http://forum-en.msi.com/index.php?topic=104805.0;wap2

An example would be the rig im using for web atm but ive almost replaced with what i typed above.This shows how much amps have increased in 4 years.

GeForce 8800 Ultra - 35A and a 500W PSU minimum

Im going to be on the safe side and say 40A as its heavily overclocked.Using my old OCZ stealthXtreme pro 600w with 52A being max load.With a core 2 duo and 12A left im pretty much at the max here so even if i wanted to put in a 590 i cant bummer! Thats the mistake i want to avoid.

My new rig with the corsair AX850 would have 70A so if i want to put in a 590 GTX

GeForce GTX 590 - 46A and a 700W PSU minimum

i can yes say 50A when overclocked?
20A left for cpu / SSD / dvdrw / nic /soundcard

Im almost at 70A there? thats pretty close would the 2500k not use around 10amps alone? any future cards pushing near 55A i cant see how i could run it and not be pushing the PSU beyong its safe limit.
