80+ gold + graphics V/A: some doubts
Posted: Wed Feb 03, 2010 6:09 am
Hi!
Looking up at the chart of 80+ gold (90% efficiency) I've come across with some ATX12V PSUs that at first sight are quite spectacular and they are <400W:
NXP
HIPRO
Delta
At second round, if you look into PDFs, in the graphics V and A, some intensity are just too low or has glitches or some not sinusoidal wave form, so: how a PSU rated +80 gold can have such waveforms? NXP example
So then, I think that the best PSU, without taking care of 80+ thing will be one that has no glitches, sinusoidal waveform, and also that has as close as possible voltage and intensity waveforms. For example, a 80+ gold will be Enermax 450W
But now, we are looking for a PSU which all these things. Could it be possible? Yes, you are looking for a Delta PSU. For example:
DPS-235W
DPS-300W
DPS-350W
DPS-400W
So, Delta has OEM PSUs but.....what the heck? They are:
- better power efficiency than Corsair, Enermax, Seasonic, etc
- 12VATX form factor
- voltage and intesity sinusoidal waveforms
- non glitch on waveforms
- almost similar voltage/intesity waveforms
- <400W models with all these specs
I am a corsair VX-450W very happy user, but then, taking in mind all these points, why going to a Corsair, Seasonic, Enermax,...? For this comparision, please don't keep in mind quiet/silence issue (you can always replace the fan/mod the fan)
Many thanks in advance
