Is this enough power?

[btvillarin]

Is a generic 300W p/s sufficient for my rig? I was going through the power supply wizard something, and it was recommending a Silencer 275 ATX. Does this mean my p/s is enough? (I'm kinda hard on cash, since I just bought that WD600AB that's coming in today.) Thanks...

<b>System Specs:</b>
Asus A7V133
Athlon TBird 850
Swiftech MC370-0A
512MB PC133 SDRAM
IBM 75GXP Deskstar 30GB
Western Digital WD600AB 60GB
ATI Radeon 32MB SDRAM
SB Live Value
3Com 3C905B NIC
HP CD-Writer 8x4x32
Floppy Disk Drive (duh)

Don't pay any attention to my chickenscratch.

I'd think that 300w is enough, since they recommend a 275w. But beware, wattage isn't everything - I suggest you look for a high quality power supply.

Asus A7V133 : 30W
Athlon TBird 850 : 47W
Swiftech MC370-0A : Not Sure!
512MB PC133 SDRAM : 32W
IBM 75GXP Deskstar 30GB : 15W
Western Digital WD600AB 60GB : 15W
ATI Radeon 32MB SDRAM : 50W
SB Live Value : 5W
3Com 3C905B NIC : 4W
HP CD-Writer 8x4x32 : 20W
Floppy Disk Drive (duh) : 5W

Your total <b>maximum</b> wattage there is 223W. Your parts may not actually use as much as this!

As usual lets divide the total by 7 and multiply by 10 to take into account the "don't go above 70% of the maximum rating". That gives us 319W, which means you will should get a 350W PSU. Given that your parts probably don't come right up to 223W, I'd go for a 300W PSU.

That power figure for the processor is a thermal dissipation rate. It's not the actual electricity that the processor sucks up. AMD made their processors with about 70% thermal efficiency. And the power for the hard disks is mostly off the 12v rail. The 5v rail powers the electronics, and it's a fractional number.

That processor and Geforce two are the two 3.3/5v amp eaters. And because they aren't powered individually, you have to have a bulky supply going to the mainboard, or hook two psu's up to it.

You've got to break up the amperages AND voltages.

yep... i would err on the side of caution.

a 300W will proly work, but it will also probably labour.

Is that a Northwoody in your pocket or are you just eXPited to see me?
