To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the TPG-1500D-T's rails. The limits, according to the ATX specification, are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).
|10% Load||27.8 mV||10.0 mV||15.4 mV||6.4 mV||Pass|
|20% Load||23.1 mV||15.4 mV||20.7 mV||9.6 mV||Pass|
|30% Load||19.2 mV||15.3 mV||23.7 mV||11.1 mV||Pass|
|40% Load||20.8 mV||15.6 mV||23.1 mV||12.3 mV||Pass|
|50% Load||22.5 mV||15.4 mV||22.8 mV||12.1 mV||Pass|
|60% Load||31.1 mV||22.8 mV||31.6 mV||18.0 mV||Pass|
|70% Load||36.0 mV||31.0 mV||51.5 mV||27.5 mV||Fail|
|80% Load||37.4 mV||33.2 mV||58.9 mV||31.6 mV||Fail|
|90% Load||38.4 mV||24.8 mV||41.7 mV||23.1 mV||Pass|
|100% Load||39.2 mV||26.8 mV||37.7 mV||24.4 mV||Pass|
|110% Load||39.3 mV||25.7 mV||35.3 mV||21.8 mV||Pass|
|Cross-Load 1||23.2 mV||13.9 mV||16.1 mV||8.8 mV||Pass|
|Cross-Load 2||37.9 mV||23.5 mV||34.1 mV||21.7 mV||Pass|
Ripple suppression at +12V might not be at Super Flower's levels, but it's still very good and among the best we have ever seen from an Enhance platform. The 5V and 5VSB rails demonstrate low enough ripple, though there seems to be a problem with the 3.3V rail. As you can see in the table above, ripple at 3.3V goes sky-high in the 70 to 80 percent load range. It's probably a design flaw, so Enhance should look into this as soon as possible. During the overload test, ripple is lower compared to the full load test because we had to run this benchmark using a lower ambient temperature (remember, over-temperature protection kicks in at around 49.5 °C).
Ripple Oscilloscope Screenshots
The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals 0.01 V) as the standard for all measurements.
Also those cables - the word "eyesore" comes to mind! I would be replacing those with some custom ones ASAP! :ouch:
Yeah it's just a crap unit which is hoping the kids orgasm over those RGB lighting, it's doing my head in but I'm sure it'll soon become mainstream then die.
Only at the TPG-1250D-T they used the new & excellent CST platform by CWT.
For all the other wattage models so far, ( 850 & 1500watt ) they used mediocre platforms by Enhance.
I had high expectations for Tt's new line of PSUs, but they were proven futile.
Also, I love the pixelated 8-bit-ish thing you've got going on with the ripple graphs on page 9. Perhaps
Otherwise, this was pretty much as expected. A useless product (the world does not need more 1000W+ PSUs), with useless features (RGB in a place where it'll be invisible in 90+% of modern cases), at a useless price point. That it performs badly as well just adds icing to the turd.
