I'm sure this forum gets a ton of these every day, so let me hop on the bandwagon too.
Will a: Antec True430 PSU be enough...

To run:
Asus A8V Deluxe
A64 3200+ Winchester
9800 Pro 256
200GB Sata HDD
2x CD/DVD opitical drives
2x 512 Crucial PC3200
SantaCruz
4 - 6 Fans

Thank you
 
yup the 430 would do just fine as far as amps goes

but keep in mind its an ATX12V v1.3 supply with a 20 pin main power connector
a more futureproof selection would be an ATX12V v2.0 supply with a 24 pin connector and dual +12V rails with even more +12V amps
that doesnt necessarilly mean more watts either, just that there is more capacity on those rails at the cost of the +5V rail typically

with each revision of the spec more amps have been shuffled to the +12V rail to reflect the needs of changing mobos and components ;)

and the 24 pin is backward compatible, most supplies actually ship with a 24 to 20 converter
 
the rule of thumb is to deduct one third of the amps that a supply is listed at
to reflect the realworld operation temperature

that applies to all the rails
you dont have a heavy draw on the +12V rail currently but that could easily change

most v2.0 supplies are 30A or better on the combined +12V rails
 
yes it would, its the latest spec and like the others of the True Power Series (which it the latest representative of), has truely independent rails (+3.3V & +5V) and exceeds spec for load regulation with 3% (spec is 5%)
and has a combined rating of 33A on its dual +12V rails

you see recently CPUs switched from be primarily powered off the +5V rail to the +12V rail
that and graphics cards grew past the power that the AGP slot could provide alone and started to need auxillary power, more and more, the +12V rail is employed for that as well
and with the introduction of PCI-E even more power off the +12V rail is required

the problem is that drives have traditionally used that rail, and a drive spinning up adds a quite dynamic load, inducing instability, so with all the components more dependent on the +12V rail, it was both split to enhance stability and substanially increased to meet the needs
 
dont get me wrong the 430 will do the job, likely very well
as to futureproofing, well its not the same game it was just a few years ago
the usable lifespan as infrastructure has decreased
evrything is just requiring so much more power
its entirely possible for you to get the Neopower and still outstrip its capacity if you add alot of storage and say SLi (dual high power graphics cards)

the Neopower is a good hedge but not foolproof
however I know youll like the fit and finish
as well as the utility value of the modular harness
 
strike that, good move
just looked up your board it requires a 24 pin main power connector
so go ahead and definately get that Neopower ;)

Ice I was looking for where is said it requires a 24 pin connector, would you mind telling where to look so I can identify this too. Thanks
 
LOL, I looked at a PIC, and the wrong one at that :rolleyes:

A8V-E 24 pin VIA K8T890
A8V 20 pin VIA K8T800Pro

sorry, looks like I actually got the wrong board, wouldnt have thought theyd changeup within the same damn model, but they are different chipsets

EDIT > if you click on the chipset links (which I just added),
then click on the PICs embedded in the webpage youll actually get a PIC large enough to see the connectors
