Cooler Master UCP 900W  (Source: Cooler Master)
The 80 Plus Silver certification has only been awarded to three manufacturers

Efficiency has been a big issue in computers and power supplies for a while now with data centers and businesses trying to go green in an effort to help the environment. Businesses have realized that saving power in computer systems can equate to significant savings in power and electricity costs across an enterprise.

Cooler Master announced its latest power supply called the UCP 900W. The UCP portion of the product name stands for Ultimate Circuit Protection. The PSU is billed as the first high wattage PSU on the retail market to be awarded the 80 Plus Silver Certification.

The 80 Plus Silver Certification verifies independently that the PSU is capable of 85% efficiency at 20% loading, 88% efficiency at 50% loading and 85% efficiency at 100% loading. Only three companies have been awarded the 80 Plus Silver certification: Dell, NXP Semiconductors and Cooler Master. Cooler Master is the only retail manufacturer that will be selling an 80 Plus Silver certified PSU to consumers directly.

The tests on the UCP 900W PSU found that the typical efficiency of the PSU at 50% load is 88.14% and the average efficiency overall is 86.52%. A Cooler Master spokesman told DailyTech, “it's [ the USP 900W] not the first 80+ Silver certified PSU, but the first retail PSU in the market which received the silver award from 80+ Silver.”

IBM has recognized that saving power and being more efficient can save significant amounts of money for enterprises and has introduced liquid cooled super computers able to run at room air.

Since when did personal computers need 900 effing watts? Back when the Voodoo 6000 was released, people scoffed at that kind of "progress." No wonder PC gaming is floundering today with so few games opting to take advantage of new tech. You're expected to get two video cards, a 1000watt CPU, and overclock your CPU to run Crysis at 60fps. What a joke.

I have a typical modern desktop computer, 250w is more than enough for me.

I don't know who rated you down, but it shows that a lot of of people have absolutely no idea how much power their computer needs. 250W is indeed enough for most people, even mainstream gamers!

From Anandtech:
Asus P5E3 Premium
8800 GTS, 4 gigs of Ram, E8500, 1 HD, watercooling
Power consumption (load, measured from wall) = 148W
Compensate for PSU efficiency 148W x 0,8 = 120W

That 120W was with the machine running prime95 etc. Even if you throw in two instances of 3dMark to suck out all the power out of the gpu, you still wouldn't go over 200W...

Majority of gamers could easily run their system with a good quality 350W PSU if the power was available from the 12V line...

Ps. 24" iMac with Core2Duo eats around 100W with moderate load and that includes the display!

Yeah with all the whining about greenhouse gases, pollution, and carbon emissions you'd think there would be a little more emphasis on lower power. The irony is that I am so far from the tree hugger type (burn the forest and to hell with the beetles and owls :P ) saving the planet is the least of my concerns. But I still have to pay my electric bill and 900 watt power supplies so I can brag about my giant e-penis is foolish. The sooner people stop drooling all over their keyboards when they see huge wattage power supply ads the better. I'm bored with it.

Been running a Corsair 520HX (520W) for the last year and a bit, powering an E6600 @ 3.3GHz, 4GB of ram, 8800GTS 640, 3 hard drives, 1 DVD writer, 3 case fans + CPU fan etc. with tons of power to spare. I don't know why you would need 1000W unless you were running a radiator for water cooling, SLI, dual socket CPU, 10 HDD etc.

Yep - I'm running 2 Raptors, OC'd 8800GTS 512, E6600 @ 3.6, 4 gigs of Ballistics at 2.2v along with more than a few fans and other accesories (D5 pump, a few ccd's, etc.) and if I run 2 instances of prime along with 3dMark06 while burning a DVD the draw at the wall is 3.3 amps @ 120V (396 watts). The PSU 'arms race' has been getting stupid lately and I agree fully with those that think this is a trend driven by 'e-penis' or ignorance.

Now, how about a review

This is all nice and all, but I'd like to see a detailed review on the PSU's rails and quality before jumping on the bandwagon. Also, who actually makes this model?

I would imagine to be that efficient, it would have decent rails as well. I haven't seen any reviews that have touched on this specifically yet, but I think that association makes sense.

Here is a list of 80Plus PSUs:

i agree. to reach that level of certification then it has to be built pretty well.

i wont be jumping on the wagon but im sure it'll get pretty good reviews

Dell has 80%+ efficent PSU's?

I've got an XPS 630 (ultra cheap gaming PC with XPS 3 year warranty FTW) with a Dell 750 watt PSU. I only have a single 8800GT in there so power isn't an issue, but I always worried that I probably couldn't be guaranteed anything close to 750 watts.

I assume Dell probably has it's 750 watt PSU along with it's 1000 watt PSU 80%+ certified. Even if they don't, if they've got one certified, the others are likely decent quality.

Efficiency, and ability to deliver the rated power are two totally different things.

You could have one 750 watt PSU with only 70% full-load efficiency but which is perfectly capable of delivering near the full 750 watts day in day out. It might draw in excess of 1000 watts from the mains when doing so, but it does reliably deliver its rated power.

Then there might be another 750 watt PSU with a 90% full-load efficiency, but becomes rather flaky and prone to early failure if loaded at that level for long. Whereas this one would be delivering the same amount of power but drawing only a little over 800 watts from the wall (quite a saving), it's still likely to go BANG! a lot sooner than the inefficient example I gave.

In practice, efficient PSUs tend to be quality ones capable of delivering what they advertise also, so the above scenario is unlikely, but you should never assume that high efficiency automatically means high quality.

is it the Acbel E8 OEM one ?

This is all nice, but how much is it?

Incidentally, another article states that the Dell's are 255W and the NXP is 270W, so they aren't even in the same league as a 900W CPU.

err, make that PSU, not CPU...

Smaller ones please

Cool now I would like to see some with less wattage. Say 400-600W as that is around what I need for my computers. Because to be honest my computer only uses about 15% of what that PSU's max load is on average. Heck I doubt my computer would draw 20% at full load..

I want

That is all. I will probably get one of these for my next system build.
