Corsair PSU

CAT-THE-FIFTH said:
The CX series have their power rating measured at 30C and are not 80+ certified. Corsair also has bumped up the power rating by adding more amps to the 3.3V and 5.0V lines.

The Antec High Current Gamer 520W has around the same number of amps on the 12V line as the Corsair CX600W and is 80+ Bronze certified.

What Corsair have done is taken CTW DSA PSUs and overrated them. This explains why the PSUs are rated at 30C and are not 80+ certified.

but do you think it could power some of the high end gpu's? such as 5870, gtx470 honest question.

TBH,they could as OcUK uses the CX600W. However,the CX600W is probably more like a 500W PSU if it were rated at above 30C and if you take the amount of amps it can supply on the 12V lines. In fact the CWT DSA PSUs which the new CX series are based on go upto 500W.

The OCZ and Antec units are rated more accurately.

Edit!!

The Shuttle socket 1366 SFF PCs use a 1U 500W PSU and this can power a Core i7 980X and a GTX580.

Even the 250W and 300W PSUs in the Shuttle SFF PCs can power a socket 1156 Core i7 and an HD5770.

so what you are saying that the CX400 could run my "overclocked i7 system"

My Spec > i7 920 at 4.2GHz and my 470 at 850/1700/2000, See Sig powered by CX400, l think not.

Yes - that should draw around 320 watts (i.e. no more than 27 amps on the 12v rail). Even the power thirsty 480 GTX and i7 can be run on a decent 400W PSU.
 
You guys have lost me now, on the box it says the following

CX600 says it is 80+ and on +12v line 40A @ 480w it also has 2x PCI-E 6pin leads for graphics card.

CX400w also says 80+ and on +12v line 30A @ 360w and only has 1x PCI-E 6pin lead but graphics card includes couple of adapters

Which is suitable for 570GTX ?

In fact where can I get one of those plug things that tells you the power draw from the plug?
 
If you're interested in the CX 400W, I've put up some images and unboxing pics of one I ordered from OcUK a while back. By all means, take a look. There's no real performance data but it might give you a better handle on what you'd actually be buying:

CX 400W
 
I had one, couldnt fault it ever, never skipped a beat and ran my machine just as good, but the fan started to clunk so i had to see it go .

Both, but some people refuse to believe a amazing little unit such as a CX400 can.

indeed, i've still got mine in it's box :p

mine ran an overclocked athlon II X4 635 @ 3.4Ghz, with 5770 and Geforce 9800GT 3 Hard drives, fans, even at full load, worked fine, never blinked once, awesome little supply.

and to Oldphart, my post said almost all cards, sure the supply would be out of it's depth with say 2xGtx295's plugged in, but most people only really use 1 card and the old Cx400W will happily power that type of system, as other people have pointed out :p

If a GTX480 + i7 can be run of a descent 400watt PSU and you saying my system draws about 320watts, a 4.2GHz i7 920 draws about 150watts by its self. So why do OCUK use a 600watt PSU in the Titan Onyx" Intel Core i7 950 3.06GHz @ 4.00GHz Quad Core DDR3 System with the option of a GTX480 or the Titan Xenomorph" Intel Core i3 540 3.06GHz @ 4.20GHz Nvidia Edition DDR3 System a 600watt PSU and the option of a GTX480 and again not a 400watt?

Its simple the 400watt for example the CX400watt + 30Amp on the 12v rails, would not have enough WATTS + AMPS to run either System.

pcanywhere > "Yes - that should draw around 320 watts (i.e. no more than 27 amps on the 12v rail). Even the power thirsty 480 GTX and i7 can be run on a decent 400W PSU.

So your saying a CX400watt + 30amp 12v rails would run my system as it only draws about 320watts + 26amps , my i7 920 4.2 draws about 150watt alone and my GTX470 at 840/1700/2000[ about a 46% overclock] will draw close to a GTX480.

Hardwarecanucks.com review > Even the GTX580 based system would need a 600watt PSU example CX600watt + 40Amp on the 12v rails -
http://www.hardwarecanucks.com/foru...s/37789-nvidia-geforce-gtx-580-review-21.html > We would recommend a good 600W PSU for this card nonetheless


Techspot review -> their test system i7 3.7GHz[700watt PSU] + 480 is drawing over 500watts.
http://www.techspot.com/review/263-nvidia-geforce-gtx-480/page13.html

EXtreme Power Supply Calculator Lite v2.5 > my system needs a Minimum PSU Wattage: 619 Watts, but in my 4th post l quoted a GTX470 > 550watt at least 35amps for a average sYstem, my system is not average.

Guru3D review of the GTX470 GPU 470 -
On your AVERAGE system the card requires you to have a 550 Watt power supply unit. We recommend AT LEAST 35 Amps in total available on the +12 volts rails (accumulated).

At pc anywhere > So your still saying a 400watt PSU will run i7 + 480 system , so the above facts are wrong that includes OCUK systems with a i7/i3 + 480 GPU run by a 600watt PSU and they should use a CX400watt PSU on their systems instead.

I know who l would trust to have the correct PSU in i7 + 480 GPU systems, do l need to say who or will l spell it out for you?

doubt it tbh, the 480 would be pushing it. 580 and 470 maybe, but not the 480, especially if OC

480's use a simlar amount of power as 2 460's in SLI
 
480 + i7 is around 360 - 380 watts. However I would never recommend someones buys a 400 watt PSU for that build. The question was 'could it run' and my response is yes, it could.

If I was using my pc flat-out for 8 hours a day, I'd probably want to keep the PSU load down to 45 to 60 percent capacity. So a better choice would be a decent 600 watt PSU. If I only ran my pc at 100% for an hour a day then I would probably be happy to run at 80 to 90% psu load.

And that is the reason why ocuk include a 600+ watt psu on their builds.

I think you mis-read/understod my post, already have both psu now from ocuk.

Yes my Corsair 400w is identical to your pictures, thanks for sharing though

The 520W HX520W can supply 40A on the 12V line:

http://www.corsair.com/products/hx/default.aspx

The Corsair CX600W is more like a 500W PSU for a modern system as most of the power draw is on the 12V lines. Unlike most recent Corsair PSUs the new CX range is only rated at 30C.

The CX600W is not 80+ certified and is not on the official list:

http://www.plugloadsolutions.com/80PlusPowerSuppliesDetail.aspx?id=25&type=2

The Corsair website says the following:

"Up to 80% energy efficiency means less heat generation and lower energy bills"

Rated up to 600W of continuous power output at 30°C

http://www.corsair.com/products/cx600/default.aspx

However,this is what the Corsair website says for the CX400W:

Rated up to 400W of continuous power output at 40ºC

It also has the official 80+ logo for the CX400W.

http://www.corsair.com/products/cx/default.aspx

It is based on the VX450W and is only rated at 400W so it can be 80+ certified.

The CX400W also has a three year warranty whereas the newer CX series PSUs have a two year warranty.

A 400watt PSU would only be suitable for low end GPU's plus system, depending on system CPU,etc, the 400watt would not give you much leeway for a better GPU and overclocking. Can't see the point in buying a 400watt PSU, l purchased a good quality 850watt PSU for my latest build plus to meet future requirement's and also l can tranfure it to my next build, saving you money in the long run.

I've read that your PSU is most efficient when run at 50% to 70% of its capacity, once you get above that it shortens its lifespan, reliabilty, due to components working harder and this could cause it to go
Bang>pop>smoke and even taking out mobo components with along it.

pc > anywhere did you happen to read my 1st post[above] in a way its simular to your last post, but l would still love to see a CX400 run a i7 + GTX480 or perhaps a one of the OCUK systems l quoted whether it be one day a week or whatever.

When l choose my HX850, l based it on what people were running their PC's on at the time, reviews and reading about PSU Efficiency. So l could run a good high spec system, deing able to run a top end GPU, go sli or xf, overclock both the CPU + GPU, etc with out any worries of my PSU going Bang and taking out other components with it.

Cat the fith is the only other one quoting PSU's [watts + 12v rails amps needed] IE - CX400 30amps at the 12v rails. The 12v rails is just as important as the number of watts it puts out, to run a PC system depending on components, will it be overclocked, etc.

Enough said, end of.
