Thanks

But what about that 800 watt supply that comes with that 10 dollar case.

A good brand 250 watt will perform better than a generic 400 watt, so obviously the most important thing is to get a reputable brand (AOpen, Antec etc.). |

Just like guitar or stereo receiver amplifiers... some of them are rated at
peak wattage, other are rated RMS. Some of the cheap power supplies to make themselves look good... probably rate their supplies according to peak output...not sustainable without overheating or becoming overloaded and suppliing inferior voltage levels and noise. Good power supplies will have overload and short protection and noise reduction circuitry and so on... in addition to what the cheap supplies offer. I think a Zalman 300W is a good starting point... and it is rated RMS. COnnect your PC to a UPS too... a cheap 500 Watt UPS keeps your system healthy too. Jeff "TboXx" wrote in message m...

Here is a link to a PSU calculator that might help.

Feel the overall weight of the supply and compare that way, the heavier the better!
Wattage ratings are not as important as the quality of components. One post stated that your board needs 90 watts and the drive needed 10..... That may be the theoretical power draw but the real world start-up current is quite different, somewhere on the order of 10~100x of what the label on the bottom of the drive says that's where quality components will shine over any bogus rated cheapy lightweight supply. -- Mainboards, Videocards & CPU pin repair. http://motherboardrepair.com "TboXx" wrote in message m...

I just went from an enermax EG-431 (79$ 2-3 years ago) that was choking when I ran 3dmark03 with an 2500xp being run as a 3200xp on an NF-7S to a 25$ 600W power supply that runs 3dmark03 just fine at 11X200. Looped for 8 hours straight in test mode. The enermax wasn't a bad unit, its 15 amps on the 12v line simply wasn't enough. 24 amps with the Lead Power did the trick. having a 9800, 3 7200rpm HD, 2 dvd's and 4 80mm fans with some other misc stuff didn't help. http://tinyurl.com/2czrp |

It will give that 15A on your 12v rail when its at 25 degrees Celsius. Have you felt 25C ? its COOL, seeing as your body temp is like 37C, when was (other than in the 15 seconds AFTER a POST) the last time you ever had COOL air coming from your PSU? Every degree of heat it rises, it LOSES efficiency, until it finally cant provide any of the rails proper current, let along all of them. Then go he http://www.jscustompcs.com/power_supply/ Fire in your CPU/RAM/HD settings (I didnt know your RAM or extra peripherals except the FANS, but I came up with 353W as your recommended PSU. That 4 year old powersupply, from the Celeron / Pentium 2 era, trying to power a r9800 and a 2500xp (overclocked even! more draw on the rails) No wonder you had problems. The Enermax PSU has 0 problems, other than it was designed for far less hungry devices and motherboards than todays computers, you putting a PSU that couldnt realistically provide the current you needed, does not mean that your POS 600w generic is better than an Enermax.

I just went from an enermax EG-431 (79$ 2-3 years ago) that was choking
when I ran 3dmark03 with an 2500xp being run as a 3200xp on an NF-7S to a 25$ 600W power supply that runs 3dmark03 just fine at 11X200. Looped for 8 hours straight in test mode. The enermax wasn't a bad unit, its 15 amps on the 12v line simply wasn't enough. 24 amps with the Lead Power did the trick. having a 9800, 3 7200rpm HD, 2 dvd's and 4 80mm fans with some other misc stuff didn't help. I have 8 amps on the 12v line in my 250 Watt PSU and run 2 7200 RPM HDs, CDRW/DVD, Geforce FX card, 3 internal fans and the biggest wattage hog of all, a P4 3.0 GHz. So what were you saying? Funny how my good brand 250 Watt with 8 amps on the 12v performs as well as your 600 Watt generic piece of ****. |

I have that Enermax 431 PS that he is referring to, and I run my system just
fine with it. Have had no power related problems at all. 1 P4 2.8Ghz (OC'd to 3.1Ghz) 2 sticks of Mushkin 512 mb memory 4 7200 rpm hard drives (2 Raid-0 Arrays) 1 CD-R 1 CD-RW 1 Zip 250 1 dvd-+/-rw Soundblaster Audigy Platinum Network Card GeForce FX 1 120mm fan 3 80mm fans If this system runs fine off of the PS, then just about any around today will.
