Almost unbelievable about that SF supply is the reported hold-up time of an amazing 26.3ms! I note many other top rated supplies barely (or even fail to) meet the ATX standard. The latest ATX V3 standard is 12ms at 100% of full load and 17ms at 80%. Again, 26.3ms is amazing.

yeah, very interesting they went above and beyond 3.1 spec by so much although their VII gold version also did 26.3 (same platform with a few different parts like the bridge rectifier). Seems they really pushed the platform further since the list of cons on the platinum is more robust than the gold version which itself reached Cybenetics Platinum.

Newegg and Microcenter sell the gold between $185 - $199, the pro on newegg is $229. Not sure if the $45 difference is worth it.

Back on the JG forums there was always a debate on hold up time if 17ms was too high or not.
 
IMO, there is no such thing as too high. The only real complainers (other than fan boys) were the makers of supplies that could not meet the standard - thus received failing scores in those tests.

The problem (for them) is, it takes a better design and bigger (read: more expensive) storage caps to maintain output for longer periods of time in the event input voltage drops below the specified voltage (90VAC for 115VAC nominal mains, and 180VAC for 230VAC nominal voltage) or input frequency drops below 47Hz.

If EVERYONE supported their computers with a decent UPS with AVR that reacted quickly, hold-up time would not be much an issue. But most users don't use UPS.

FTW, most decent UPS with AVR detect and can cut-over to battery power in 10ms or less.
 
we're on 3.1 already?

What are the note-worthy revisions between 3.0 and 3.1? I know i can google it but hope you guys can explain in a more simpler manner without the techno-rave :)
 
Well after a couple of months with hardware problems I finally realized that a dust filter on my Silverstone SST ST1000 PTS was completely filled with dust and was causing overheating while playing a sertan game. It would be nice with a temp censor on the PSU that one could see in e.g. Hardware Info

Ummm, not that I know of. Pretty sure V3.0 is the latest - at least for PSUs.

Introduction - 2.1a - ID:336521 | ATX Version 3 Multi Rail Desktop Platform Power Supply (intel.com)

3.1 is for the main ATX standard covering motherboards, cases, etc.

PSU 3.1 info

  • Changing an ATX v3.0 PSU to an ATX v3.1 one only involves changing the 12+4 pin header to the new one (given that the PSU already has one).
  • If a PSU uses 2x 8pin headers on its modular board to power the 12VHPWR (or 12V-2×6) cable, it is automatically ATX v3.1 compliant (provided it follows the rest of the requirements).
  • PSUs with native 12VHPWR (or 12V-2×6) cables can be ATX v3.1 compliant if they already meet the ATX v3.0 spec.
  • ATX v3.1 PSUs allow for a lower hold-up time (12ms instead of 17ms in ATX v3.0), which, in my opinion, is a big step backward!
  • ATX v3.1 PSUs are NOT ATX v3.0 compliant because of the lower hold-up time. This is a first for the ATX spec! A newer spec does not cover the previous one in all aspects!
  • There can be ATX v3.1 PSUs WITHOUT the 12V-2×6 connector, which have lower transient response requirements (150% peak instead of 200%).

LOL Been there. Still, I will never have a case again that does not have removable, washable dust filters.

Nice but, I don't see it happening. How would that temperature value get to any sort of monitor?

Where inside PSU will the sensor go? What type sensor? There is only 1 unused (besides several "common") pin socket on the 24-pin connector. All the PSU makers would have to agree to use that one, or another cable or an entirely new cable. Then all the motherboard makers would have to agree to use a corresponding pin on the motherboard. All the chipset/BIOS makers would have to agree on how and where to distribute that value so the various hardware monitors could use it.

It is near impossible to get that many hardware and software makers to agree on the time of day, let alone a "new" feature.

That said, I would suspect it was not your PSU overheating and but the CPU, GPU, RAM, or a motherboard component. This would be especially true if your PSU is bottom mounted over its own intake vent. I note that is a semi-fanless operation PSU meaning the fan stays off when cool and ramps up to full speed as temps rise. Even with a quiet case, since PSUs are mounted next to an outer case surface, I know I sure would hear the fan noise.

Either way, I use and recommend Core Temp to monitor CPU temps in real time. Under Options > Settings > Notification Area, I have mine set to display "Highest temperature" only to avoid cluttering up the System Tray area. Then when I see my temps starting to hit and sit above higher than normal temps, that is my cue to clean my filters.

The reason they're at the top of the hold-up chart is the same reason they're at the bottom of the in-rush chart lol (big bulk caps).

It's an odd supply, beating competition in some categories and losing pretty bad in others. Super Flower has always been an intriguing company to me as I've had several of their supplies (with EVGA logos on them) and they were the supplier for some of the best EVGA supplies ever made. I Think the main thing they haven't tackled in the US market is their marketing. With their EVGA relationship ending years ago (and EVGA walking off into the sunset in general), I haven't heard if they're doing OEM supplies for anybody else these days or just selling under their own name. Their universal connectors always weird me out though. I kind of like the idea, but they just seem bulky to me, so I wonder if they would ever do one with a different kind of connector. Also, their fan seems pretty noisy to me.

I first came across them manufacturing PSU for Kingwin and I believe Xion. Not sure if Kingwin is still around. Their quality seemed to go up a notch for EVGA but they also outsource a decent amount of their production.
