I read about this in a copy of PC format. It did extremely well in tests and was given the gold award while being far from the most expensive psu in the tests.

Who would use it? Demanding users! You'd need to have a lot of drives (Both optical and Hard) a meaty graphics card or two to justify this but still, for those of us that demand quality without paying an arm and a leg, this little beauty is under £100 delivered (Super saver). This is the world's 1st 80 Plus Silver certified high wattage power supply; powering systems with enough juice at 88% efficiency.



More info can be found on the manufacturers website:

Overview

The new Coolermaster 900W UCP PSU - Certified with 80% Silver Efficiency Rating

CoolerMaster UCP (Ultimate Circuit Protection) re-defines the standard for efficient and durable computer power supplies. The UCP 900W takes center-stage as the world's 1st 80 Plus Silver certified high wattage power supply; powering systems with enough juice at 88% efficiency.

Innovative circuitry layout has resulted in industry-leading efficiency levels, thanks to the high performance active clamp switch design, dual-VRM circuit boards for maximized 12V conversion to 5V and 3.3V and re-design of circuit board layout.

The UCP series is meant for powering the high-end system setups; with circuit protection in mind to prolong the life-time of the power supply. Features that enable this includes: soft-start circuitry to limit inrush currents (a Cooler Master unique feature) and the usage of quality components such as solid capacitors and intelligent fan control.

With ever increasing global demand on, it is becoming more important as a power supply provider to offer efficien energy. We are ecstatic to have accomplished this with the introduction of the UCP 900W.

Features

1. VRM(Voltage Regulation Module) Circuit offers high efficiency and Power density.
2. Compliance with the newest Intel standard ATX 12V V2.3
3. Compliance with the newest SSI standard EPS 12V V2.92
4. Ultra-silent operation with intelligent 120mm fan speed control
5. Eco-design for energy and money saving by Active PFC.(>0.9) / high efficiency(>88%)
6. Power Failure Detector will light up when OVP /OCP / OPP / SCP / UVP /OTP occur
7. Soft-start circuit A protection mechanism that limits the input inrush current by delaying the actual power-on of the PSU to prevent damage to it.
8. Green mode PFC control circuit by intelligent PWM power conversion
9. By using a single 12V switching circuit design you get a more efficient AC to DC conversion which leads to an overall more efficient PSU

Thanks mate, it's been ages since I posted anything but I've just started scoping stuff out as I'm planning building a new gaming rig.

I got one of those samsung HD103UJ 1Tb drives you had posted a while back, kicks much ass mate thanks again for posting about that. :-D

Been searching the web today for components for my next build, this goes to the top of the list for a PSU, good find!

Remember that the PSU is often an overlooked component and can be the cause of many stability problems, the power may seem like overkill but the more the better as you never want to be approaching the limits of your PSU...
suspended#4
What components are you planning on using? Cause you wouldnt use anywhere near this amount with a core 7 +4890, if you had 2 4890's youd still wouldnt need that much lol.

Not a bad price at all, i prefer my Xclio units so far though as they are silent and extremely stable with the price that puts them under everyone else!.

Voted hot.
#5
The only negative thing that I can say about this that it's not modular, if you've always used standard PSU's then that wouldn't matter to you anyway. As for the deal itself this is a superb price for a 900W PSU and CoolerMaster make some of the best PSU's, the 5 year guarantee that CoolerMaster always give you is also proof of how confident they are that these won't let you down.
#6
Looks like a good price, but a lil on the premium side, especially considering its not modular. I would suggest checking out OCZ and Corsair, they offer very high quality power supplies, of a similiar spec, for very reasonable prices.

Also someone mentioned Xclio, my experience is the build quality is a bit low, first one I had made a loud buzzing after shutdown, replacement one had the fan blowing the wrong way...

I've got a FSP 700W PSU which cost me £27,and that's more than enough power for the average user.
Wouldn't have thought that many people would need 900W.
Useful if you're running masses of stuff though.

after you have spent £ hundreds on a system build and your cheap psu goes BANG !!! it can destroy your cpu+graphics card +RAM +mobo and anything else in there , they make more expensive psu's for a reason they last longer work more efficiently and give the wattage is says on the box ,

Absolutely, and it's something I overlooked on my first build and paid for it when I had constant problems all fixed by spending a decent amount on a PSU. Will never buy another el cheapo PSU, you'll end up wasting money rather than saving money in the long run!

Didn't you think to check your facts before you posted ?

His £27 PSU is the 700W FSP700-80GLN - it most certainly is a 700w unit, along with offering an 83% efficiency.

Pick one up yourself for £69 - http://www.scan.co.uk/Products/700W-FSP700-80GLN-SATA-PCI-E-83plus-Eff-Green-ATX12v-201-EPS12v-OEM - if you're interested.
Or wait till the next time Scan put it up on their Today Only page for £27...

But we aren't talking about a cheap no-name PSU - we're talking about a branded FSP unit. Their PSUs are used by Antec, OCZ, Silverstone, and Zalman, along with many other "high-end" names !

yes 2 should be fine...

We tried a watercooled I7 and 3 GTX280s SLI'd at work on the 1000watt psu from the Dell XPS but it kept rebooting itself :x So we used the 1200watt one :thumbsup:
#14
I'm planning on building a i7 920 rig, using a ati 4850 as the gpu.

Silence is off utmost imortance to me - and I'd also like to get a modular psu

cheap is also a high priority - as after all, its only a power supply

on the basis of those criteria, any recommendations from you lovely folk?

I see why you think its only a power supply, but please dont by a cheapie 1000W PSU for £25, go with a well known brand because the cheap ones simply say high wattage ratings to get your attention, when stability should be more of a priority, and you get that with better well known brands. Personally I like the Corsair PSUs, but Seasonic are very good too IMHO.

I would never go back to a Non-modular PSU, my Corsair HX620 is awesome.
#23
There's more to choosing a PSU than picking the highest Wattage. What about the amperage on the +12v rails? The one listed here is reasonable at 25A, 22A and 20A. (Another one mentioned in this thread is, I am led to believe, only 15A .)

Yes, buy the asus 4850 - great cooler and wisper quiet normally
Oh, and get a 30-40 quid CPU cooler (with a case big enough to house it). Most other things will be noisy

I used to have an Antec Truepower PSU. Everyone raved about how great they were at the time, and how it was money well spent, and that the watts rating was more accurate than cheaper PSU's which over-rated themselves - so I plumped up for it. 3 years later (just out of warranty) some of the voltages went down and the PC wouldn't work as it should, then eventually it went pop. So in that case I spent the extra money for nothing. So these review sites, sure they can be sent a PSU free of charge by a MFR in return for a review on their website, they can prod a multimeter in all it's sockets, pull it to pieces and look inside - but they can't tell you what it will be like in a couple of years time.

I would buy this though, coolermaster is a good brand.

Me too. Mine went pop too, just out of warranty. Then I tried a Hiper Type R, it went pop inside warranty so at least I got a replacement. I'm now using Corsair, will wait and see how it works out.

most PCs will not use more than 350W - 900W is massive overkill.

It is only 88% efficient when running near capacity

if you only drain 400W from it, you will see the efficiency reduce considerably - so you may be paying twice as much as you need to power it - and the inefficiency going to heat up the insides of your PC!

but lets sweep that under the carpet :)

In high end systems - dual graphics cards, 4 hard discs, 4 dvd drives etc etc you could quite easily exceed 600w. If on the other hand your idea of a decent PC is a cheapie graphics card, one hard disc, and one optical drive, and a celery processor you're probably right :D
#33
I think 900W is too much even for a monster pc. I have a q6600, 2 raptors, 1tb seagate, a backup sata hdd, 2 dvd-rw, one HD4870 and it only uses 260W under load, 220W in idle.
I have a Zalman fan controller with a front panel that tells me in real time how much power I use. :thumbsup:

On the other hand if you dont use too much power the PSU will stay cool thus silent.

I cheched how much power uses a low end PC, about 130W under load and 90W in indle. That is with Celeron Dual Core, one hdd, one dvd-rom and HD3650.

you must of been very unlucky then, my unit is solid and its made by CWT who make the majority of all PSU's like the corsair units and antec etc. Its reliable and cheap what more could you ask for :).

Kinda correct but all 80+ effciency ratings follow a strict guideline, has to be 80(for bronze and like 85 for silver) at 20%/50%/100%. So using this on a low end system is fine!.

Just looked into detail about 80 PLUS and its actually best to use 50% load but 20 and 100 are the same so its win win. http://en.wikipedia.org/wiki/80_PLUS

Desktop Hard Discs consume little power so adding 3 extra drives will add less than 30W.
4 DVD drives! Not exactly a normal requirement and in use they consume about 15W each, so having 4 of each drive only adds about 75W if they are all used simultaneously.
A HD 4850 with a Core i7 will typically max out at well under 250W DC (~300W AC). Add a second HD 4850 and the extra drives and you’re looking at well under 400W DC.
So you can hit 600W with such a setup but not as you suggested easily as you’d need to use two VGA cards that are pulling over 200W DC each.

Below are examples of system load with an i7 3.2GHz and keep in mind that the power figures listed are AC input and Power Supplies are rated for DC output.
e.g. The GTX 285 SLI consumes 529W AC which assuming an efficiency of 85% means it’s DC output is only 450W.
