what happen if no enough power supply on our system?

[han888]

bsod? or anything else? thx

i am currently have:

2 X p3-700@868
abit vp6
2 X alpha cooller
1ghz hyundai memory pc133
matrox G400
3 X sunon case fans
sblive value
2 X vantec hard disk cooller
16 X pionner dvd-rom
yamaha 16 X 10 X 40
3 X 30 IBM hard rive

and with 300w ps, is it enough 300w for my system?

I think a 300W would be fine man. Just my humble opinion.

Oops didn't see the 2x p3 part. Boy, I just don't know then.

Someone here will know!

 

[Doctorweir]

Should be enough...finally depends on the Ampere-load the 5V and 12V stream can deliver...Watts aren't everything...
But if you wouldn't have enough power, the system would let you know...in some way...eventually freezin' all the time or not even posting...

 

[han888]

thx for the reply

At least one of the voltages will droop. Try monitoring the voltages and then do a random read test with the hard drive, or burn a CD. If the 0-5V lines don't stay within 3-4% of their rated values or the 12V within 5-6%, then the power supply is straining.

It can be much worst than simple voltage droopings causing intermittent errors or reboots...

This kind of failure mode is one of the reasons why you guys should have listened to Jim Macintosh on not trying to save a few dollars spent on a power supply.
The problem is caused by the logic-level voltages upon shut-off dropped out early from being too far loaded before the 12V went down, which 99.9999% of the time will kill any mobos the very first time that event occurred. Some mobo manufacturers do have protection circuits for this but few, and generally they never worked worth a sh*t anyhow, not when a designed 3V part had to take a hit of 12V. >>

* BSOD's
* Unexpected reboots (not that there's much in the form of expectable reboots ).
* Data corruption (writing to HD)
* Similar such nasties.

Generaly system instability.

I would feel a little uncertain about 300W with that system. It *should* be OK (depending on how much your devices leech). If all your drives spin up for instance (going out of hibernate, for isntance), you could have some nasty power-spikes which can cause your problems.

Might want to go for 350W. You also might want to calculate the Amps you are leeching off each channel &amp; then check with the PSU. It should give you the ratings on there somewhere.

thx all, i am currently have a strange issue with my comp, when i run norton, it's kick out the application ( close by itself), and also IE, fix it utilites,. and sometimes the system got bsod

 

[ajskydiver]

I worked on a friend's Compaq with a pathetic PWR supply...

on a cold boot, everything worked fine until he restarted...

warm boot, either the CD-RW or DVD Drive would fail to work and &quot;disppear&quot; in Windows...until shut off and cold boot again.

My system has been really gay since I put in my two IBM 60 GXP's. It ran fine for a week after I installed them, then the system started randomly rebooting and wouldn't come back up after that, until I left it off for a few minutes. And it would lock up half way through the win2k startup, or get into windows and then the video would shimmer and the whole system would lock up.

So i've ordered a 400 watter, and I'm not going to reboot until it gets here, heh.
