how much power?

[muc0n]

I have an 800mhz athlon, two cdroms, two 7200 rpm hard drives, radeon 8500le, siig ata133 controller card, 320mb of pc133 ram, network and sound card, and 4 fans. what type of power supply would i need. i currently have a 200W max and i dont think that is enough. what are some problems i might see if this i do not have a big enough power supply. thanks for any help.

That should help give you an idea.

I'm no expert on the power requirements of all your equipment but lets do some rough numbers, ok?
Let's try to take the info the guy gave us in the first link
and see how it works out. If I understand some of what he's saying correctly then.

Video card 30W
Floppy 5W
Disk Drive 40W (2x20)
CDRom 20W (2x10)
Case Fans 12W (4x3)
Mobo 25W
Ram 20W (3x8 = 384MB)
Processor 50W
PCI cards 15W (3x5)
==============
Roughly 215W When everything is running at the same time.

Considering you should be at 60%-70% of max I'd say you should have 350W.

Also, depends on which voltage rails this stuff is on and how the PSU is configured but anyway....

Lets see who corrects this cause I'm sure I'm not right.

The loving are the daring!

heh, thanks for the help. i looked at the ps faq and all the voltages and stuff made no since to me so you did a lot better than i did.
