Cybenetics Introduces Mining Ready PSU Certification

They should also add 80+ Platinum rating as a requirement. A few percent difference in efficiency makes a noticeable difference in power usage on a 1+kW rig running 24/7.

I'm surprised there isn't a motherboard manufacturer jumping on board with a 40 PCIe x1 slot x99/x299 motherboard or a bunch of specially designed risers, splitters and extensions. Then partner with a PSU manucturer to make a 50A 220V PSU (11kW) for it. Unless the chipsets don't allow each PCIe lane split to its own slot.

Serious miners would probably go for something which could run on a dedicated 220V outlet in the US. As a lot of countries aren't limited by the 110V 15A standard.

Cybenetics has its own efficiency certification program called ETA, which is much more detailed compared to 80 PLUS programs.

A PSU that it is highly efficient with 115V, will be highly efficient with 230V as well (actually 1-2% more).

So if we have two PSUs tested with 115V input (X and Y models) and X has higher overall efficiency than Y with 115V, the same will be the case with 230V.

How is the quality of the fan going to be determined? From Hardwaresecrets' article here, a lot of fans that claim to be FDB aren't actually a real FDB fan. Are the fans going to be opened up and inspected, or is the manufacturer's word going to be taken for it?

Additionally, since sleeve and rifle are not allowed, what about variants of sleeve and rifle? For example, long life bearings, hydro dynamic, and all those other ones that have crazy names and don't come to mind.

There is a more comperhensive piece about fan bearings etc at Toms.

The fan's detailed spec sheet should be provided along with the test report and the fan will be taken apart if there is any doubt about its bearing.

All the variants of plain sleeve bearing will be rejected. Rifle bearing is also an enhanced version of the sleeve bearing, which however doesn't have the lifetime of an FDB/HDB. Indeed many manufacturers and brands use weird names or just call their fans rifle or even HDB, while they are plain sleeve so someone has to pay extra attention in this section, in order to find the true bearing type.

A note about rifle bearing fans since some state that there are some of high quality. Given that we always keep an open mind in any area (this is the only way to move forward), if we do meet a rifle bearing fan with a proven lifetime of at least 40-50,000h (under 35-40C) then we will accept it and we will make a special note about this. Nonetheless, most rifle bearing fans out there are just renamed sleeve-bearings or just have minor modifications, so this is why this category was excluded at the first place.

In general the field is very dark when it comes to fans since very few brands share the actual test sheets of the fans, which have some information about their lifetime. And even if you have the detailed test sheet you still don't know how accurate this is. Also don't just look at the provided lifetime without checking at which ambient this is supposed to be. A fan can have 40,000h lifetime at 25C but as the operating temp increases its lifetime decreases dramatically and inside a mining PSU you don't expect of course an 25C ambient.
