Re: Power supply build quality pictorial. part 2
Why wouldn't I want it? Does it do damage over long term use? Cause instability?
I doubt it... and in most cases, it probably is so... thus, not something I'd personally care about. If it works and is not damaging to the system or causing instability, I couldn't care less.
The only PSUs that I'd really avoid for a new build is gutless wonders and those old half-bridge group designs with barely any protection. Anything above that is fair game to me.
I think calling them "brutal" is a bit of an overstatement. Yes, they are quite large... but if the PSU can handle it without tripping, who cares.
Most PCs today still die because of crappy manufacturing with RoHS materials and components running too hot (GPU, CPU, MOSFETs - usually right at edge of their limits, just to squeeze all performance possible to get top $$ to the manufacturer) and not because of not using a "newest top-design" PSU.
Eh. It depends. I've seen both. Low and mid-range OEM PCs (with PSUs typically less than 400W) still get a beaten-to-death group design... though lately, I'm seeing more and more of those "external power adapter" "laptop in a desktop PC case" machines... which typically do output a single voltage - so you're right about those, at least.
Meh.
This hardly matters, though. As long as voltage ripple and noise are in spec, nothing should get damaged or degraded over time.
I have plenty of older PCs that have drops on the 12V rail from ~11.7x Volts under load to ~12V idle. PSUs recapped, so pretty sure noise is in spec. Never had an HDD die because of that, even though we all know that's not too good for them. The real HDD killers are high-noise gutless PSUs (or PSUs with failed caps).
Because it's not really a risk.
... though technically you are right in a way: if you are building a high-end expensive PC, then it makes sense to spend some extra money on a better-designed PSU. But for any plain PC build? -Just put any decent PSU that can keep the PC working reliably, close your eyes, and press the power button. Ain't going to stress over what topology the PSU is, again, if it's a decent brand PSU (with decent caps), it works, and the system is stable. Too much voltage sag? Watt-ever!
