new psu means no more onboard sound?

[guynexdoor]

I want to upgrade my 300w PSU to a 500-600w.

Apparently, I was told that if my new PSU doesn't have a 5v line, I would not be able to use my onboard sound that is on my mobo. Please see my specs below.

Is this true? Or can I just buy any new PSU and not have to worry about sound issue?

As far as I know, all PSUs have 5V line. I don't see any reason why you wouldn't have onboard sound with a new PSU. What PSU are you planning to purchase that doesn't have a 5V line anyway ?

What idiot are you taking to. All PC PSUs have a 5V line. Its standard.

it might not have a -5V line, but that isn't a problem.

Some motherboards still require a -5V for Creative onboard sound.

From another forum:

I recently purchased the MSI K8N Neo4/SLI motherboard and the manual DOES say it needs a -5v rail from the power supply unit. However, I have a Seasonic S12 600 power supply, and it has no -5v rail. So it looks like you are ok with whatever power supply because MSI realized this problem and fixed it with a simple solder on the newer version of the same motherboard.

I have the MSI K8N Neo4 Platinum (NOT the SLI version) and the manual shows that -5v is NOT required. Now what that implies for the SLI version of the mobo, I don't know. I did note that the K8N Diamond does require -5v (according to the MSI web site).

If you aren't using the onboard sound then the issue is moot.

All PSU's have a +5v Rail.
Only a handful of PSU's have a -5v Rail.

You need to consult your motherboard manual to find out if you need a -5v rail. If You don't, 90% of the psu's will work just fine (not to say you should go out and buy a raidmax psu or something because of course your still gonna want a decent psu).

Looking at manual right now, and I can't anywhere that says I NEED a -5v rail...
Still looking.

It has to be referring to the -5v rail.
-5v and onboard sound would imply that the manufacturer is using the -5v to supply power to some form of opamp. I know all the realtek chips have integrated opamp and derive the negative voltage internally, but that might not be the case for other brands of chips.
