why everybody emphasizes PSU

[munisgtm]

please tell me the reasons for why in so many threads you guys put extra weight on PSU ?

Long Answer: Others can do it better than me

Short Answer: Simply put, most of current hardware draws a serious amount of power whether it's your brand spanking-new CPU or GPU. It's also not the just the quantity of power but also the quality of power that matters. Power Supplies are a major factor in determining the stability of a high-end PC, particularly when it's overclocked. Power supplies can also be a major pain in the ass and a major blow on your wallet if they fail and kill/damage other components in your computer if/when they fail.

Because i saw one explode. A loud bang (louder than rifle fire, quieter than artillery) a flash of blue light and the smell of burning. Not happening again.

Because a bad PSU can destroy hundreds of dollars in damages?...

Wouldn't want that to happen huh?

 

[munisgtm]

thanks!

1. A quality PS supplies steady, clean power to your components. It can last through several upgrades or rebuilds and keep chugging on.
* You never have to think about it. :thumbsup:
2. A cheap PS can fluctuate in its output and cause reboots, lockups, etc. It has a short life span.
* You're always posting in here asking why your system is acting up. :thumbsdown:

The importance of the PSU is also very dependent on where you live. Temperature, moisture, and, most importantly, power quality, are all important. For example, the PSU is much less important in most European countries that in most parts of USA.

I live 17 degrees North of the equator: how's that for a tough environment?

i live in southeast asia more specifically Pakistan in Karachi ,temperature here stays here like 32C to 38C in winter it gets like 22C so PSU is very important to me then ,right ?

High temps can spell disaster for cheap caps often found in low-end and generic PSUs. I would look for a Forton-Source, Seasonic Enhance, or Enermax (Liberty line); all of which are high-quality and rated for at least 40c.

Yes, the power supply is the foundation for a stable system so it shouldn't be skimped on. But one doesn't have to spend a LOT of money (of course that's relative - what's inexpensive here may be a week's pay to someone elsewhere) to get a reliable unit. You can often get excellent buys on used PSUs. You just need to really know what's what.

The quality of the power available is much more important. Is the voltage stable? Are power-failure frequent? You can probably call your local power-plant and ask.

2000 dollars of equipment destroyed by a cheapy lil dinky PSU? Hell no...invest on better PSUs.

Hey, I live in nearby Rajasthan And I will tell you WHY PSU is important for our areas.. My processor is P4 and it produces heat like a house on fire, heat which is hard to lose in the extreme temperatures. If you have a poor PSU you can't install more fans and its ****** effeciency means the PSU is probably producing more heat than it loses thru its fans.
If you have a good PSU , you can install more fans with good cross ventilation ( more heavy duty fans too) and the PSU will have higher effeciency due to which the heat it produces will be much much lesser. In the end its a sweet sweet bargain.
Oh and the basic fact that PSU is THE thing on which your whole rig runs is true throughout the world and you dont wanna play fast and loose with your PSU.

A good PSU is essential for a stable system.

Unfortunatley, we had little guidance as to determining what brands/types of PSUs meet these requirements.

I'd guess 90% of the posters in this thread would rattle off some brand or model number of a PSU based on it's total wattage, or ability to run multiple LED fans and over-priced video card. Chances are that same PSU is made on the same production line in China as less glamourous 'junk' PSU's that come with budget computer cases.

By the standards mentioned above, the 250watt PSU's used in my servers are crap and need to be replaced with gamer PSU's because they don't have enough wattage, and the correct Western name on the outside.

Hey Just think About it!

If you have a crappy PSU with 50% efficiency and run a big rig on it that requires around 400W ... 400W will also have to go waste as HEAT and thats just from the PSU. 400W is a small heater and that is something I can't afford in my case and place where temps reach 50 deg. celsius.

Same, lesson learned. Only took out my GF4 somehow...

19° for me!

Now ill surely buy a good quality PSU i dont want to destroy or damage my system at all ,super thanks to you all! but the big problem is finding a good PSU is hard in Karachi the only brands i have seen are Cooler master and Aopen and Antec(very expensive),any good PSU you guys could recommend ?ill be buying a new rig early next month .

 

[fire400]

statistics show that a cheap/bad PSU will be more responsible for a system failure than any other computer hardware part.

not only that, but you risk damaging many other elements within your computer chassis, like the mobo and CPU, perhaps video card and RAM, etc.

I'd find the article for you, but since this thread is so simple, you search on yahoo and find the details our yourself

How is that? Most of the responses are on point and well thought out.

I would hope

AOpen are relabeled Fortron (most model numbers are the same as Fortron (e.g. FSP350-60PFN) - decent PSUs, but most are of old designs with 12V rails totaling less power than the +5 and 3.3V rails together, when for today's systems that should be reversed with the 12V rail(s) totalling over 50% of the total power.

Too many people neglect the importance of a quality PSU, and when someone has a bad experience, they make a point of trying to warn others of the risks involved with using an inferior PSU. Basically, you can't go wrong if you make an informed decision rather than being ignorant and close-minded. Read reviews, ask questions in forums like this, and don't dwell on a few posts by disgruntled customers.
