Power Consumption requirements

[Majesty]

Hi,

I wanted to add a new 40G HD in my computer when I got this little problem. After having plugged it, I press the Power switch and nothing happens!

So, an introduction is required. I currently have:
Abit NF-S 2.0
Athlon XP M 2500+ @ 3200+
Volcano 7+ Heatsink+Fan
4 IDE HDs (200GB, 160GB, 120GB and 80GB. All Western Digital.)
ATi Radeon 9700 Pro (not O/C)
OCZ PC3200 Platinum Special Edt
Adaptec SCSI Card
SCSI Pioneer DVD-Rom
SCSI Yamaha 8416 CD-RW
Creative Labs Audigy 2 ZS
2 USB peripherals (MX510 Mouse + Guillemot Gamepad)
Floppy Drive

All that powered by an Enermax 480VE-P (430W PSU). So, that's about it. I have installed an IDE Promise Controller Card to plug my 5th HD and just after having replugged everything, my computer wouldn't boot up! I thought my PSU was busted. But after having unplugged everything but the mother-board, my computer booted. Once again, I've plugged everything, nothing. That's weird. I've unplugged everything (again) and plugged one by one my HDs, trying to boot every time I've plugged one. And I've been able to put my computer back on it's knees. But I didn't dare plug my 40GB HD.

Someone know what have happened? Is my PSU big enough to had another HD without having power variations?

Thank you

According to THIS, you're close to maxing out that power supply. Five hard drives is a lot to have in one box. The heat alone could be your problem, those things can get hot.

If you TOTAL the power consumption before adding the controller
and extra HD, it would require approximately 320 watts.
(based on 512 ram, 2 system fans, keyboard and mouse).

Adding the PCI card and HD would bring it up another 30 watts to
approx. 350 watts. The PSU you have should be able to provide the power,
but as with anything Electronic, even PSU's with the same power rating from
the same LINE are not created equal (i.e. Your Mileage May Vary).

Did you try the 40gb drive by it self?

Did you try the 40gb drive by it self?

No, I didn't. I'll try it in my other computer see if it works well. But that shoudn't be the problem.

Heat might be my problem, as bamacre stated. Since I've moved, I've got some random reboots in NWN. There was a climatised air system where I used to live.

But I still wonder why my computer wouldn't boot with all my HDs plugged. Anyway.
