Silverstone HELA 850R Platinum ATX 3.0 + PCIe Gen 5 PSU Goes on Sale

[btarunr]

Silverstone HELA 850R Platinum is probably the first ATX 3.0 + PCIe Gen 5 PSU you can actually buy. It's listed on Amazon for $215. Silverstone had debuted the HELA series in late-2021, but originally with the 12-pin Molex MicroFit 3.0 connector for seamless connectivity with RTX 30-series Founders Edition graphics cards. It's since been updated with a newer connector for PCIe Gen 5. The 850 W PSU meets ATX 3.0 standards, as well as offers an 12+4 pin ATX12HPWR connector. The PSU can handle +100% excursions for 100 µs, a requirement for offering the ATX12HPWR connector. Inside, you'll get a single +12 V rail design, Cybenetics Platinum efficiency, and a 135 mm fluid dynamic bearing fan. Other connectors include six 6+2 pin PCIe, two 8-pin EPS, and a large number of SATA-power and Molex connectors.

Here they come! Good to see the solid companies releasing something worth paying attention to. I look forward to seeing some reviews of this and the Seasonics soon.

HELA is one hell of a PSU name.

Don't know what Cybernetics rate their minimum Platinum rating at but wasn't it supposed to be above 90% efficiency on either 115V 60Hz or 230V 50Hz
because 115v 60Hz it doesn't even make the platinum grade unless it's showing only 100% load efficiency
115V 60Hz

they don't state at what load though atleast Clearesult.com shows you the load efficiency at 10% 20% 50% 100% load

It's good to see these connectors and specs coming to more sensibly specced PSUs - the 1000W+ units that came first are just fundamentally uninteresting to me, and uselessly oversepecced for the vast majority of PCs. 850W is better, but I'm looking forward to this stuff coming to 550W units and thereabouts.

I mean, Cybenetics do link to test reports right in the results table where you must have found those numbers? That report quite clearly states that those are average efficiency numbers. Here's the report for this specific model, and the requirements for Cybenetics Platinum are these:

Who is the OEM on this unit? Any idea?

But at what PSU load are they taking those "Overall Efficiency" numbers at is it 2% 25% 65% 75% 90% 100% yeah they don't tell you that little but important tidbit no they do not, atleast at Cleareview they gave you the efficiency numbers at 10%, 20%, 50% and 100% cybernetics on the otherhand think that just giving a range of efficiency numbers is good enough which it's not

Your questions are answered in the source link above the screenshot I posted. It is literally the first thing said below the heading on that page. Please don't be lazy.

Contrary to existing methodologies we plan to apply more than 1450 different load combinations in the DUT (Device Under Test), which with the interpolation of results, can provide up to 25,000 measurement points, while current methodologies only take three to four measurements. The overall efficiency will be the average of all measurements, which cover the PSU’s entire operational range.
