Corsair AX850 850 W
9 May 2011
Summary: The AX850 proved to be a solid performer. Although its voltage regulation was not jaw dropping, +12V and 5V rails stayed under 3% and only 3.3V reached 4% deviation. The high efficiency levels even under very high ambient temperatures, the excellent ripple suppression and especially the great performance of all rails in the Advanced Transient Response tests showed the high class of this PSU.
Pros: High efficiency even at low loads, Great ripple/noise suppression, One of the very few PSUs that passed successfully all Advanced Transient Response tests, Very quiet operation since the fan does not spin at low loads and when the PSU's temperature is low, High manufacturing quality, Fully modular, 7 years warranty
Cons: Loose voltage regulation at 3.3V, but still within 5% range
Excerpt: 2 Flares 2 Flares × A short while ago we reviewed Corsair’s top of the line AX1200 PSU and it walked away with a score of 9.5/10 and our top award. It earned this by delivering record breaking efficiency (93%) with an incredibly potent and ultimately stable power delivery.
Summary: Corsair con questo prodotto ha indubbiamente centrato il bersaglio; non siamo ai livelli di tecnologia visti nel modello AX-1200, ma dobbiamo ricordare la diversa tipologia di utenza a cui i prodotti sono destinati.
Regolazione di tensione praticamente perfetta, efficienza a livelli esemplari, completamente modulare, fanless fino al 20% di carico e poi comunque molto silenzioso, esteticamente gradevole, a questo punto, manca solo il prezzo...
