IF I can manage it is this a good choice and will it handle upgrading to an AM2 with a dual core CPU and a 8800 GPU??http://www.newegg.com/Product/Product.a ... 6817151029

This is even better, and for slightly cheaper too:

What about this then??http://www.newegg.com/Product/Product.a ... 6817139003 I thought the active PFC was a good thing on the Seasonic??

Zipzoomfly has the one Dan mentioned for even less.... $105 shipped... It's $99 shipped at Buy.com... For an extra $20 you get more PSU and modular cables on the HX series than the VX series. Worth it IMHO.

That would work, but for better 'future proofing' why not bump it up to the HX520 still. With the price finder nate mentioned its only $25 more.

The HX520 does have Active PFC as well.

You're from Dallas Texas, active PFC basicly get you nothing in return for the money paid.

Active PFC is much more beneficial in places other than Dallas Texas. Usually foreign places in Europe for example, where active PFC could return as much as 8% extra efficiency for the money.

Wow --> "in Europe, power supplies are now required to have either active PFC or passive PFC."

There're actually people in Europe who also could calculate for the active PFC return value just as I do.

Active PFC is a must

Definitely so for places where hi-impedance low grade WTF power distribution very typical, requiring much better input power correction before use like Europe.

Dallas Texas is not prone to What the f--- power distribution like Europe.

Nein I'm only gonna say this once, I've already warned you via PM. Act civil or your in for a vacation.

perfect Nien, all I was saying is try to explain yourself a little better. Your undoubtedly a knowledgeable person, just explain yourself so we all can learn

OK sorry I should have simply stayed out of it.

Active PFC didn't correct for PSU internal inefficiency, it corrected for external wasted power from source power deficiency. Nothing wrong with your source power? There's nothing for active PFC to correct and no wasted source power to recover.

I normally avoid answering questions not asked for. "We" never asked and I avoid giving answers to "we", only to individuals asking for answers.

I aslo answer for myself, I don't answer nor represent for "we".

You'd nothing to be sorry about and you'd asked a good question.

Assuming TXU is your power provider in Dallas Texas. If your house power is deficient then tell TXU to fix their power distribution, because the whole house is wasting power you'd paid for... don't just buy an active PFC PSU for your computer.

TXU can build a hi-quality, hi-cost infra-structure power grid, distributing power to their customers efficiently with little wasted power loss.

Or TXU could build a WTF power grid, then have their customers buying equipments compensating for the wasted power loss causing by the lo-quality, lo-cost power grid.

If TXU customers can't buy only properly made equipments for their house which could handle the WTF power grid. It is TXU customer problem as they'll still have to pay for the wasted power loss. A simplified example below...

TXU sent 100W of WTF power to your PSU. Without active PFC to correct the WTF input power... your computer used 90W, 10W didn't get into the PSU. Your TXU power bill would still be for 100W of WTF power.

This applied to all electrical equipments in your house.

So like, Active PFC is magic and makes the bad power into good power?

Also, don't we all have "WTF power" ? Isn't there always a waste of power somewhere in the distribution network?

Electrical supply is a somewhat complicated thing but from what I know we do all use more power than we actually need to power our devices because of oversupply. I know there is some other word for it but I call it oversupply. TXU has to send out enough power to "allow" all our devices to run even IF they arent all running all the time. The meter only measures one way so once the electricity passes your meter you "own" it even IF you don't use it. I would thing that Active PFC would be worth extra money simply because it makes sure that the power supplied to your accessories is right. Meaning IF your DVD isnt running it gets no power until you start it up. Usually the DVD player is using a very small amount of energy to hold it in " ready" mode as do all the electric motors in your house.

Power had to be spent for the input correction, but 1% power spent for 9% wasted power recovered the net gain is still 8%. 1% spent for 1% recovered would make active PFC a waste of time, and decreasing reliability by being another entry point for PSU hardware failure.

Just because there're places which should have active PFC in their PSUs does not mean everyone had to have it.

Zertz wrote:Also, don't we all have "WTF power" ?

I don't know about "we" power distribution in Canada, never been there and never wanted to be there.

I'd been in the Far East, there're many many "we" in the East with WTF power and could really use active PFC PSUs. And then there were places where power distribution just plain scary, I'd always mumbled a few prayers to the ancestors for their blessings before plugging in any equipments.

I'd have to admit the Japanese had it made as their power distribution is second to nobody in places I traveled to within Japan. For few exceptions, a lot of "we" Japanese definitely would not need nor want active PFC in their PSUs, but that won't stop the ones didn't know any better.

The ideal perfect voltage sources have zero input impedance and zero wasted source power, no one including your power provider could build ideal perfect voltage sources. But they certainly could build them well enough for practical purposes as perfect.

Perhaps all CPUs and other hardware providers should add active PFC to their processors and other hardware to recover wasted "oversupply" "WTF power" from crappy PSUs?

Personally I prefered my PSU was made well enough which I would not have to do so to all electrical components I had and it is far more efficient this way.
