500W or Dual 350W PS?

I'm upgrading my PC and purchasing a the Cooler Master Stacker case which supports dual PS's pretty easily. My question, would I be better off purchasing Dual 350W PS's or one nice 500W or higher PS?

By prices I can probably get two 350W PS's for the same money or even less.

Any thoughts?
 
Dual Power Supplies is never a good idea (unless it is a backup arrangement).

One little "fluke" might create potential differences and blow the circuit in a spilt of a second.

:sun:
 
Would a good 350W PS support a high powered machine? I'm think AMD Althlon64 3200+.

Thanks for the info Jack, I hadn't heard that before but it makes sense!
 
I have a 400W PS and I guarantee it is way way overkill for what I have, but my config is probably unlike most here because, for example, i only have 1 HD etc.

depends on what you mean by high powered. use that PS calculator for starters?

Mine would be almost identical with an extra hard drive thrown in. Maybe I can keep the 350W PS I'm using now. Less money spent, can't complain about that 🙂
 
I'd bite the bullet and drop around $100 on a good quality 450W+ PSU. The Antec TruePower 480s aren't too horribly expensive and ought to run even a SLI system without problems. Don't cheap out on the PSU, it is just about the most important component in your build.

Would you mind explaining? Its not like the same piece of hardware is being supplied power by both PSUs and its not like they would wired up in series. The only thing the PSUs might share is a ground.


Id have to think dual 350 watt PSUs would be far better than having a single 500 or even a 700 watt PSU.

350 should be fine. See sig.

It'd be plenty, assuming it was a quality PSU.

I agree, espeically when we are talking about the new True 380S models that come with the Sonatas. My wife's computer has a newer Sonata that has 24A on the included PSU's +12V rail and it has no issues running a power hungry chip (she has a LGA775 3.4GHz Prescott on a 915PBL), so I personally know how nice the Antec True Powers are despite their lower (or should we say "more realistic"?) wattage rating.

I think, though, that if you are you are buying a new PSU and want some headroom to support things like SLI and dual core chips, the extra cost of getting a quality 420W or 480W is worth it. A good power supply could potentially last you through 2-3 upgrades/system rebuilds, so it is worth it to spend a bit extra to make sure you have all the power (and connectors) you need for the future.

Mine isn't even the newer model, I have an 18A 12V rail.
 
Hmmm...OK. I have a 350W Enermax Whisper in my current PC. I will most likely be buying a new PS because I'm turning my current PC into a domain controller/file/print server so what would you guys recommend. Obviously, the less it costs the better...but I'm not one to not buy something because its $20 more if I know it will last and is high quality.
