i don't understant whay buy Psu for 400 Watt for 3000 and Up When u PSU for 500 Watt for around 800 to 1500. I don't why people would buy coolmaster PSU Why ?
 
first of all u need to post this in right section .....

and there are many thing in PSU specification other than watts .....

i am not in mood to write all things coz it wil be too long ..... but google is ur friend
 
We have a lot of money to splurge, so what the hell, might as well spend 6-8k on a PSU!

If you want help buying a PSU, let us know your budget...
 
they have multicolour LED fans , and have matt black finish, and look cool in expensive see through cabinets :P
 
Why Buy Costly PSUs? The Power of PSUs in rated in 'amps' A computer power supply typically is designed to convert 110 V or 230 V AC power from the mains to usable low-voltage DC power for the internal components of the computer. The most common computer power supplies are built to conform with the ATX form factor. This enables different power supplies to be interchangeable with different components inside the computer. ATX power supplies also are designed to turn on and off using a signal from the motherboard (PS-ON wire), and provide support for modern functions such as the Standby mode of many computers. Good PSU Brands Such as Antec, Cooler Master, OCZ, Enermax etc. have their PSU made out of Really good quality componants, typically, the heavier the PSU is the better it should be since being heavy means good quality heatsinks and componants are used and it can take loads of load.Most computer power supplies have a large bundle of wires emerging from one end. One connector attached to the opposite end of some wires goes to the motherboard to provide power. The PS-ON wire is located in this connector, and usually green. The connector for the motherboard is the largest of all the connectors. There are also other, smaller connectors, most of which have four wires: two black, one red, and one yellow. Unlike the standard electrical wire color-coding, each black wire is a Ground, the red wire is +5 V, and the yellow wire is +12 V. there's also a 3.3+ rail, the more power the PSU can donate to the rails the more stable the pc will be. EVERY, GOod quality PSU has rated Amp levels printed on it, a Antec 350W PSU for example can take around 18a on 3.3+ Rail, 20a on 5.5+ around 22a on 12+ v Rail (Note that many new PSUs have Dual +12 rails due to power regulations, which doesn't allow any rail to supply more than 240va on any rail) If you are looking for a good quality PSU that won't break the bank yet offer good performance, i suggest you buy VIP 400W PSU, which sells for about 1.5k and offers admirable performance.
 
of all the replies..this newb (^) posted some informative reply other than rahul...;)

me also noob when it comes to these PSU ratings...so any help other than google recomendation ///:P
 
Let me explain. Would you rather buy a TV made by Samsung, or one made by the neighbourhood electronics repair man from scrap parts? Quality is everything, but I do agree with you - why the hell would anyone buy a coolermaster PSU? The state of comp elex, which requires us to buy such shit just to run a PC, is pathetic.
 
i wouldnt mind buying the one the neighbourhood repairman made (but not from scrap parts though )

for any given price, the local thing is often better than the imported
 
I would take the middle path... I certainly cannot afford to spend 6-8k on a PSU. My max budget for PSU is always b/w 2k to 3k. Thats why powersafe 500w was my natural choice. Some people just go for too much perfection and blow a lot of money on PSUs.
 
^^ Its not for perfection.

When you need the power you need the power.

Id rather not risk my Motherboard, CPU, RAM, Graphics Cards, Hard Disk, and Pump, now for that matter, using a cheap PSU.

If you spend so much on the other parts, Why or WHY?? would you compromise on the PSU?
 
I always wondered about this - If a good 400W PSU is running my system perfectly, is there any point in spending more for a 550W PSU? Are voltage readings through DMM enough to tell us if the PSU is good or bad? Or do we need something else?
 
zhop, you're right... 550w could be overkill for certain computers especially if it doesn't draw so much power, and if you already have a quality 400w PSU. You can try the eXtreme PSU Calculator to figure out approximate power requirements of your system :)
 
Zhops, using a DMM is the best way to check a PSU as motherboard sensor readings checked through a software tool may not always be accurate....

Additionally, given the highly bloated ratings on most PSUs available in the market, it is definitely a good idea to check the voltage rails on your PSU whether you are using an el-cheapo or an uber expensive PSU

to test, put all the parts of a pc un PC under load, e.g start a filecopy from your optical drive to the hdd, (to stress HDD/Optical drive) and simultaneously run say 3dmark05/06...(To stress CPU/GPU/RAM)

while the above are running, use a DMM to test the voltages on the 5V/12V rails from a free molex connector...for testing the 3.3V rail, you'll have to use steady hands (don't attempt when drunk ;) ) to check the 3.3V rail on the orange line on the ATX connector....

the voltage variation shuld be within +-5% at max on all the rails....

If your existing PSU passes this test, no need to get another :)

On a side note..whats wrong peeps?

A new member posts a questions (a sensible one at that, grammar not withstanding!) and for a long while, all he gets is sarcastic and pointless replies :huh: till another new member decides to post something sane?
 
Even cheap DMMs are fairly precise on the 20V DC range ...a whole lot more precise than the motherboard sensor reading....

and even if someone is scared of testing the 3.3V line, the 5V/12V rail variatins would be a good indicator of the PSU quality
