Enermax Noisetaker AX model

[Rickten]

I'm looking at the EG475AX-VE (W)SFMA and it looks pretty sweet. However I can't seem to find it anywhere. Does anyone know where I can purchase this model.

What's the difference between that model and the EG475P-VE-SFMA? (I just ordered the EG475P-VE-SFMA yesterday.)

ax model has Active PFC while the P model doesn't. I can't find anyone selling the AX model though.

I found the EG465AXVE-FCA here. Not sure if it's exactly the one you want, but close as I could find.

Just in case anyone was wondering, I emailed enermax and they said March 2004 the AX PFC models of the new noisetaker will be available in the US.

can u explain to me the difference between the PFC model and the P model?

here's a good site describing what PFC is and does

I've been waiting for this to be available for some time, and I finally found it in the US!

Look around mwave.com and newegg.com. They both have it "in stock" today. MWave has the EG475AX-VE for $109, and newegg is $115, as of 4/3/04.

Be careful, that text could potentially be misleading. Remember, they want to sell you their higher priced PFC models.

In many countries (including the US) domestic electricity meters do not measure power factor - in this case you get absolutely no reduction in your electricity bill if you switch to PFC. In Taiwan, you way well have to pay heavily for low powerfactor, in which case these supplies may be highly economical - but do not assume that you will get any monetary saving until you have checked with your electricity supplier.

Your electricity company would like you to use PFC because it means their infrastructure has to work slightly less hard, while they charge you full price. This also means cleaner power and steadier mains voltage. The overall increase in efficiency (if, indeed, there is one) is exceedingly small, because the electricity infrastructure is relatively efficient and active PFC circuits are potentially quite inefficient.

The other advantage of PFC is for larger consumers of power (e.g. a computer lab or 'cybercafe') - PFC means less current on the mains supply. This means either lighter gauge wiring can be used, or you could install more PCs on a single circuit.
