I see some of them use HIGH POWER design, such as these models: http://www.xbitlabs.com/articles/cases/ … html#sect0

These are decent designs, doing up to 1000 watts well within specs... other models use old designs from CWT which are ok for their low wattage.

Anyway... really not needed for that configuration.

Guess, builting a pc server isn't like the real one because of the PSU

.. Anyways ...
@Mikael912 1200 w PSU conscerns upgrades to sli or crossfire.... ATI radeon 5970 (once fastest card in the world) was spending about 300w with a full load... That means that in sudden power spike all componts would be damaged somehow... From my experience, and I deal with servers, the best way to protect other components from being ruined or damaged is best PSU.
For that reason I have UPS 1200 VA here...

Anyway, what sort of chipset is now available, that supports 6 slots of ddr3 ?

that would be the old intel x58 chipset, but it's EOL now. it's successor is the x79 chipset, it's using 8 ddr3 slots for quad channel interface.

There's no such thing as damaging your computer when the video card has sudden spikes of power demands.

The 5970 is indeed consuming 300w in the worst case, which is basically only synthetic benchmarks - you'll measure games that abuse a video card so much on the fingers of one hand.
A second 5970 in crossfire won't double the power demands, as crossfire is not 100% efficient - basically you'll see both cards consume at best a maximum of 250 watts each.
The processor, even overclocked, won't use more than 150 watts and the rest of the parts don't use much power - only 5 watts per memory module and about 10 watts per hard drive.

So basically your power needs would be in the worst case 300+300+150+50 = 800 watts. A 850 watts would have been enough, especially if it's a high quality one.
Most high quality power supplies can actually do more than they're rated for, as they spec them for lower wattage to get them in a higher efficiency category.

For example, I would have recommended you a Seasonic X-850 that has up to 92% efficiency and is rated Gold, but can manage over 998 watts until it turns itself off, but the efficiency drops to Silver or Bronze levels at this load... see the review here: http://www.hardwaresecrets.com/article/ … iew/1169/8

It's more expensive than that 1200w psu, probably... but it's gold efficiency. As it is right now, your 1200w psu will have about 70% efficiency at 200-300 watts load your system has, so you're losing about 100 watts each hour or 1kWh a day (if you keep system running 8-10 hours a day) - the Seasonic psu has about 82-85% even at such low loads.

Basically - you would recover the price difference for the Seasonic model in about 6-8 months, if you have the system on for 4-8 hours a day, and after you'd save money on electricity.

-

There's a huge difference between VA and Watts - that 1200VA UPS doesn't mean the UPS will be able to handle your 1200 watts psu at maximum load... it means something else but it's harder to explain.

What you need to know is that the UPS will probably handle at best a 600-700 watt load (the psu can be rated for more but UPS probably won't manage to keep the system up if the psu draws so much power) and depending on the battery it has, it will keep the system up for 1-2 minutes at such high loads.

-

Yeah, if you want 6+ memory slots you have the x58 that's now end of life or the 2011 sockets (x79 chipset) that does up to 8 slots ( 2 pairs of 4 modules). This is on regular consumer boards.
There's some AMD chipsets for regular boards that can do more than 4 but I'm not sure now

There are workstation motherboards that do more, such as the dual g34 boards like this one: http://www.newegg.com/Product/Product.a … 6813131643

which has 8 slots per CPU and otherwise it can be used normally, if you want. Just have to get the Premium versions of Windows 7 that support 2 cpus or Windows 2008

Of course, I uploaded the wrong picture - my bad!
It's sunny here atm so the picture isn't the best but I will upload another picture later tonight.

Upgrading from a gpu thats more than 7 years old I am more than happy with it to say the least.

It plays everything I throw at it bf3 on ultra for example and it doesn't go over 65 degrees. It's actually very quiet for me also! I can honestly say that the case fans are louder (In intense shoot outs BF3 Ultra) and the the gpu fan does it thing auto, no manual settings.

I don't think you're gonna get a less techy review if you tried! :lol:

I'm quite the noob so if I can do it mate I'm sure you can.

My room is also very cold at the moment so it may heat up to 70ish when ambient temp rises.

Really cramped I'm afraid, can't manage to sort the cables like I want to in this case due to the backplate being extremely thin and holes arent really that big.

Aswell as the 24 pin connector is too short to be drawn through the back.

This is with my old gpu but not much has changed.

I recently stumbled upon a great comprehensive article about power supplies, but after many tries i cannot seem to find it anymore

Power supplies capacitors wear down in use so after 3 years of use the PSU may have lost around 10-30% of it's original peak performance. Especially when you are running your PSU near it's maximum load it can handle.
Even the certifies bronce/gold/platinum are faulty, they are done in a labratory conditions that never happen in a real world. Just like ISPs promise to give you 100Mb connection and you get closer to 70-80Mb connection (if you are lucky). So if you buy 500W PSU certified @ 80+ it should give you 400W according to certificate but only if certain specifications are met. PSU load is max 80%, air is max +25C etc. the list is endless. At the end your bronze certified 500W PSU gives you around 350W at maximum load when it is new (if you are lucky).
When PSU has worn down too much and it is running on it's limit it can damage other components on your system, this has happened 3 times to me. Last time my PSU melted the power cable that goes in to motherboard...

So when you buy a new PSU i would suggest that you invest in a gold/platinum certified PSU that has more power than you will need atm, PSU is usually the last part you will change in PC anyway so don't be cheap on that part.

Power consumption on a gaming rig is only going to go up in the future.

an make it as smooth as possible, sort of like this:

In the case of the pictures above the power supply gives 12v but due to the design, you can see that within a second the voltage has lots of ups and downs. Capacitors and other components (like coils) try to make it look like in the second picture. The ATX standard says up to 100mv (go from 0 to +50mV or -50mV) is allowed but you want this to be as smooth as possible, because the electronic components in the PC have a harder time working if it's not smooth.

Capacitors have a semi-liquid paste in them between layers or material rolled like a scotch tape inside that metal case. That's called electrolytic. The quality of that paste determines how well those capacitors will hold energy in them and how well the voltage is smoothed out - if this paste degrades (for various reasons), the capacitors will hold less charge or not be able to smooth out the voltage going out on the wire anymore.

This electrolytic holds the excess charge coming in the capacitor (for example when the lines go up a lot in the first picture) and use this charge to fill up the lines that are very low in the first picture... and the result is what's on the second picture.
But, if the voltage receives is too high, a very small area of this electrolytic gets damaged, it's sort of like a lightning happens between two layers of material inside the capacitor and in the paste between those layers a very small part of the electric gets burned and simply no longer holds charge or changes into gas... how to put it... imagine you unroll the material inside a capacitor, it may look like the surface of your monitor screen, now imagine a pixel is dead.
Heat works about the same... if the capacitors stay at very high temperature, parts of this substance degrades and turns into gas or simply won't hold charge anymore.

In time (hours to days of operation), parts of this damaged electrolytic reforms itself, the capacitors self heal.

Now about lifetime... most capacitors are rated as n hours @ c temperature - that doesn't mean that capacitors are meant to work for only n hours, but rather it means that if the capacitor is subjected for short periods of time to temperatures as high as c degrees, the capacitor is guaranteed to work within the rated specifications as long as the total of those small periods of time is not higher than n hours.

For example, a capacitor may be rated for 5000 hours at 105c - this means that if every day the capacitor stays at 100c for one hour, the capacitor may only last 4-5000 days until it no longer gives adequate filtering. This is because when the capacitor no longer is at 100c, the electrolytic can heal itself to some degree.
But this value scales up proportionally with lower temperature. A 5000 hour @ 105c capacitor could also be named:
7.000 hours @ 95c ,
10.000 hours @ 85c ,
16.000 hours @ 75c,
30.000 hours at 60c,
100.000 hours at 40c
so a capacitor could work AT LEAST 10-15 years easily within specifications (because when temperature is lower the capacitor heals itself to some degree), if the temperature is maintained low and quality of manufacture is good enough.

-

So no, capacitor aging doesn't cause your psu to lose 10-30% of its peak performance and especially not after 3 years or some pre-determined amount of time. The period varies depending on who the manufacturer of the capacitors is and how good their quality is (that's why high quality psus use Japanese manufacturers because they have great quality control and reliability) and also matters how well the power supply is cooled. Some manufacturers cheap out on heatsinks to make the psu lighter and cheaper to ship but other manufacturers prefer to keep the fans at low rotation and leave the psu hotter, just to advertise the psu as silent.

Cheap budget power supplies are never able to give as much power as they're rated, but that's because they're old designs from the times of Pentium 3, not because of capacitors. Simply put, they're designs that give a lot of power on 5v (because that's what was used to power the CPU on old motherboards) but nowadays the computers want a lot of 12v - these cheap power supplies can't offer it.

If you want good stuff, you get power supplies from brand names... modern designs cost from 45$ and up. There's no such thing as a good 20$ psu.

That comparison with ISPs is crap, because only in some countries ISPs give you less than advertised - I'm here with a 100mbps connection and can use it up to 100 mbps anytime.

Most quality brand name power supply nowadays actually can do MORE than they're rated for, but they're advertised as lower wattage in order to be able to advertise on the box that they're 80+ bronze, silver or gold.
Those 80+ tests only require power supplies have at least 80% efficiency at a 20% load, 85% at 50% load and 82% efficiency at 100% load.

So, for example, if they don't have a 500w power supply that can do 85% efficiency at 50% load, they can take a 600w power supply and label it as 500w and maybe configure it to automatically shut down if you use more than 550 watts.

I just want to be clear - the rest of your post is bullshit, there's no such thing as "bronze certified 500W PSU gives you around 350W at maximum load when it is new (if you are lucky)." - brand name power supplies WILL DO what they're advertised for.

Actualy You are WRONG,
Before I got a deal for servers I serviced a lot of dell optiplex's psu's. Main reason for mailfunction and general malfuction (mainboard) was the PSU... Is gave 3.8 v on the green with ne gnd and 12 looked like 18 v before dying .... Thats like it.. Any servers, DELL. I repair their PSU's. Whole lot die when the capactiors fail .... Whole cooling goes through the psu and even quality components in psu die...

Got that? Roger, Roger: Roger;Roger...

You don't have to fucking quote my whole wall of text.

Quote:

What did I say that contradicts what you just said in the text above to say I was wrong ?

I'm not wrong. You show a special case, where those power supplies failed for other reasons. You're either too stupid to known the exact reason why they died and blamed the capacitors swollen in them for the failure, or you're intentionally omitting the facts. Just because the power supply shows after it died 18v doesn't mean that it died first and took the system with it, it could be the other way around.

Dell had several power supplies with problems - some were made with some particular series of capacitors that had manufacturing flaws ( United Chemi Con KZG or KZJ which need to be replaced on sight, Nichicon HM between 2000 and 2004), others were simply bad designs (Bestec power supplies which used a simple one transistor design for the 5v stand by therefore overheating and shoving tons of ripple on that single capacitor filtering the rail and when this capacitor died it took the motherboard with it).

In addition, you sure picked up a fine example to brag with... optiplex are basically the shittiest systems made by dell, there were even lawsuits against them due to the bad quality:

http://www.hbsslaw.com/cases-and-invest … lloptiplex

Quote:

Consumers who purchased a Dell Optiplex computer may be eligible to participate in a class-action lawsuit filed by Hagens Berman in the U.S. District Court of New York.

Dell Inc. allegedly sold Optiplex computers between 2003 and 2005 with defective motherboards and failed to properly address these issues with consumers. As a result, several people claimed they experienced serious hardware failures with their Dell computer, which materialized as a blue screen or thermal error message, a system shut down or an inability to reboot properly.

Failures to the computer’s motherboard, home to the central processing unit or the computer’s brains, can cause permanent data loss and can also cause overheating, which may lead to a fire, the lawsuit states.

Dell first learned about its motherboard defects in January 2004. However Hagens Berman attorneys have information indicating the computer manufacturer knew long before then.

The suit claims Dell intentionally sold various Optiplex models with faulty motherboards, and knew about the nature and extent of the problem those models would have on consumers. The suit also states that Dell used faulty motherboards for consumer repairs.

Dell estimated that 8 million of 11.8 million units sold have faulty motherboards

Optiplex systems are just bad.. it's not the power supply that made them die, it's the stupid design of the motherboard and the undersized cooling solution - we're talking Pentium 4 processors that pull a lot of power, the vrm circuitry on the boards gets overheated and demands lots of amps from psu which have crappy diodes and switching chips, they're designed to be cheap - as good or bad as they are, the capacitors will eventually die in those systems because of the heat inside.

A capacitor by itself doesn't cause the voltage to go up from 12v to 18v, it's physically impossible - all power supplies have circuitry in them to prevent that. What they can do is, when capacitors go bad their ESR goes up, which can cause imbalances in the circuits so you'll see more ripple on the rails.
In more special cases, they can die shorted and some mosfets can start to oscillate without some capacitance on the ouput. Dell's power supplies are simply so bad they don't have over voltage protections and over current protections.

In addition, some cheap power supplies use group regulation, which means that when one of the voltages goes up or down, the circuitry scales the other rails accordingly, so it's possibly to get 14-15v on the 12v rail when they die.

This doesn't contradict what I said, capacitors just don't die after three years or some predefined time - they can last a lot if they're quality parts and working at adequate temperatures.

Too much "Hardware" talk - not enough pictures of "rigs"

Hahaha...gotta love your posts Angelitta, wow. Anyway, very good explanation of PSUs, and I completely agree about Dell. I work on Dell Optiplex systems too, and you are spot on about them being some of the shittiest PCs made. The design and component quality is pathetic. We see these things die all the time, for any number of reasons.

Oh, and Mikael, I approve of the picture!
