Cross-Load Tests And Infrared Images

Our cross-load tests are described in detail here.

To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 25,000 possible load combinations with the +12V, 5V and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12V, 5V and 3.3V) as point zero.

Efficiency Chart

The efficiency sweet spot is between 150W and around 880W, where you can expect readings between 90 to 95 percent.

Infrared Images

Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

The PSU's internal temperatures are fairly normal. The bridge rectifiers operate at around 93 degrees C with the PSU delivering full load for a prolonged period. This temperature level isn't a problem for the GBU15L06 rectifiers; combined they can handle up to 30A of current at 115 degrees C.

    I do not see anywhere the limitation regarding the need of Flash Active X 15 and only that, in order the PSU's software DPSapp to operate. Is there anything changed? I own one of its little brothers the Toughpower 550W and on my system the DPSApp refuses to run on an Active X version higher than 15.In fact on the download page there is a note saying

    "※Note: The Adobe Flash Player ActiveX 20.0.0 version or above might NOT be compatible DPS G PC App."

    or

    "※Note: The DPS G PC App requires Adobe Flash Player Version 2.0.0.270 or above and Microsoft .NET Version 4.5 or above."

    hm I am not aware of this flash/directX issue. In my system I just installed the DPSApp and it ran fine. I have all updates installed. However this App still needs work and they should abandon the flash platform IMO.

    In my case, I had no Flash on my system at all. I consider it dangerous and useless. But in order to operate DPSApp I first installed the latest version of Flash and the DPSApp crashes every time i try to open the GUI. Only on the v15 I manage to make it work. :sarcastic:

    PSUs in the >1kW range should deliver at least 3.5A-4A on 5VSB.

    Why? It is the standby power? What modern system needs more than 15W standby?

    it isn't the system that needs it, but the devices that you might try to charge through 5VSB when the PSU is in standby.

    so, there is absolutely no reason to buy this over the aging AX1200i or even the not-as-fancy HX1200i... in fact, if you buy this unit you either live in a country where corsair PSUs are hard to get or you are a moron.

    it failed the hold up requirement, regulation and ripple is mediocre at best, it's hideous and single rail designs really need to go from PSUs this powerful. 100 amperes is enough to arc weld! if the DSP malfunctions and send 100 amps down your motherboard or GPU, it'll set your house on fire. this isn't really a problem with old school analog designs. but with anything digitally controlled, bugs are always a concern.

    AX1200i is a way better performer in pretty much every metric, has a 10 year warranty these days, and individually sleeved cables are relatively cheap and readily available.
