Quiet PSU for P4P800 Deluxe

I was advisedto post this question at this forum.

I'm turning a PC into a PVR for my parents. It will be housed in a home theater style case that will sit in their entertainment center. I'm concerned about noise. I just bought a CPU heatsink/fan that is supposed to be quiet. I don't think the case fans make much noise. That leaves the PSU.

Can anyone recomend a PSU for this setup that will run real quiet-like? I don't expect to add any components other than what I've listed below. So I'm not worried much about future components sucking up too much juice.

Would a 400W PSU work? Under 400W? I have an fairly quiet 350W PSU sitting around. Using it would require an adapter to power the CPU, but would 350W even be enough?

What do you guys recommend?

Hello & welcome to SPCR!

I'd say that the 350watt PS will be fine, unless it is a unit with an "optimistic" rating -- what brand is it? What sort of an adapter do you need?

It's a Sparkle FSP350-60BN 350W. When I bought it, I didn't realize that the P4P800 Deluxe needed a specific ATX power connector, which is why I bought the Antec 550W I have now.

That connector is what I need an adapter for. I don't know what it is normally called, but in the manual it is listed as 4-Pin ATX12V. I will need to convert one of the existing outputs from the Sparkle, into the thing that fits in that square 4-pin ATX12V slot.

I think the Sparkle is supposed to be a decent PSU. So assuming the 350W isn't an optimistic rating, you think it will be enough to support all of the components that I've listed?

According to Newegg the FSP350-60BN already has the 4-pin 12V CPU power connector, so no adapter needed, see this picture:

jaganath,

That picture is for a FSP350-60BN-S model which must be slightly different from the one I have. Mine doesn't have that connector. It has everything in that picture minus the 4-pin ATX connector and the SATA connector.

350 Watts is plenty for that setup. If you do plan on getting a new one rather than trying the adapter with the Fortron/Sparkle Power, I would suggest either a 330W Seasonic S12 or 380W Seasonic S12. The 380W might be quieter under heavy loads since it has larger heatsinks, but it will be more expensive. Not sure how much more expensive, but you can check Newegg for that.

Cool. I'll give it a try then. I've already ordered the adapter.
