Are they the same psu? - Page 4

post #31 of 41
Continuous rating actually doesn't mean it can do its full rated wattage indefinitely. Depending on the unit it might last some hours or days or weeks. But unless you make a habit of running LinX and Furmark concurrently for weeks at a time, you aren't going to have that issue.

As long as the internal temperatures of the PSU are in spec, and build quality is solid, I don't really see why not? For most "good" PSU's, it's not like the continuous rating is completely on edge of what the PSU can output reliably (except for a few mediocre/older ones) for long periods of time.

For example, I probably wouldn't expect to run a CX430 at full load for extremely long periods of time... however I wouldn't say the same thing for like, a Seasonic X-560.

You don't argue with Two Cables and Phaedrus....

Anyway, what Two Cables said is right. An overkill PSU is not better than the right PSU

If we're going to cover old ground again the right PSU is a subjective opinion, what's right for you might not be what's right for someone else... running around telling people their PSUs are overkill and debating their reasoning for said purchase is getting a little totalitarian isn't it?

Bottom line... it's a personal choice and when all factors are considered the marginal difference (purchase & running costs) is a good trade off in some people's point of view (or situation), thus if a slightly higher rated quality PSU can be had for the same cash outlay as something also of quality that's adequate then why not get the bigger unit? there's nothing wrong with that at all

Except usually it's not a personal choice, but an uninformed opinion that bigger is better. Usually no "decision" is made, it's simply accepted as true that more watts is safer/better/faster/stronger. Which is why I do what I do.

I'm surprised noise (acoustic, not electrical) isn't brought up more as justification for getting a larger PSU, since arguably that's one of the more legitimate reasons. The PSU's noise depends heavily on the fan and fan profile, but most units tend to be noisier at 80% or higher of max load, or maybe 50%, or however its set.

Then again, people usually aren't debating over the range of 300W vs. 400W. With the PSUs usually being considered, you'd need some hot and noisy multi-GPU setup to use that much power anyway, so the PSU noise is often not the culprit.

That excuse would have held more water years ago, but now with the plethora of high quality, highly efficient PSUs with semi-fanless or at least low-noise operation that are available (SeaSonic X based units, and now Superflower Golden Green/King) that excuse is much weakened. Usually you can get quieter operation for your mid-range system by going with a SeaSonic X650, than going for an 850W unit, for the same price or cheaper.

Or if you run one of the distributed computing projects like Folding@Home like I do. That's why I went with a bigger PSU than I actually needed since the system would be running at 100% load 99.9% of the time. Maybe I don't need it, but for the extra $15 I spent I feel more comfortable with the extra 150 watts or so of power. If it wasn't for that I would have gone with a 450-500 watter instead of the 630 that was on sale.
