I just recieved a Powerstream 520w to replace my Truepower 430w. It came with a Euro plug and I live in the UK. The plug that came with the powerstream says 10a 125w, my Truepower plug says 10a 250w. Can I use the Truepower one on the OCZ?
Thanks for your time
Care to exchange???
My powerstream came with a UK plug and I live in Greece :D :D :D
Seriously, I just turned the 110 to 220 volt switch, threw the cable away and connected the PSU with my UPS. My UPS has "slots" like the ones found on the PSUs (not regular plugs). I didn't read any of the "cord" info that you mention. Didn't think the cord plays any serious role as long as the plugs do the job... Am I doing something terribly wrong here??
No Idea :P The company are sending me a UK spec one now so it's all good.
Also I didn't think of checking the volt switch so you just saved me a power suppy :P
errrm.. my psus have active pfc so it doesnt matter 'bout the switch, i just use any old power lead lying around in my room. it doesnt really matter as hardly any pc's/psu's use more than 3 amps.

Off topic...
Just saw this remark and wanted to make sure...
The OCZ powerstream does NOT have active PFC right??
I checked the box and didn't notice it anywhere, so it's pumping 520 watts all the time?
It's passive PFC.Quote:

Ok I've read the article a couple of times (the last 2 months :D :lol: since you posted it ) along with a couple of other ones.
Can someone please confirm these 2 points...
My OCZ 520ADJ (Bought from pc-memory-uprgrade) don't know about international version but it has a 115/220 switch has:
1)passive PFC
2) does NOT suck 520 Watts CONTINUOUSLY weather they're needed by my system or not!!!
I understood that if it had active PFC, it would "suck" more accurately the needed watts than the passive PFC. Is this true?
(overblown) example so that there is no misunderstanding...
If I plug the 520ADJ in a pentium pro with a 1Mb pci vga it will NOT draw 520 watts (and charge me accordingly in the electric company's bill). It will draw e.g. 100 watts. Is this right??
Sorry about this post guys....
No, the PSU is not drawing 520w continuous. It will draw slightly more than an Active PFC PSU, but not very much.
Many thanks for taking time to answer my stupid off topic question Stevil... :toast:
np ;)
So the only differance between OCZ 520ADJ and OCZ 520ADJ-EU is that the non EU model comes with the wrong kind of cable and that is has passive pfc wich makes it consume a bit more power?
not even that.
Active PFC is for when voltage to the PSU is unstable and varies more than about 15v in either direction.. thats about it.
In north america the voltage is pretty decent unless you live way out in the middle of nowhere or in a spot with bad lines or something.. In Europe the voltage is a bit less stable I guess... ;)
Hehe that might apply in Greece or something.Quote:

EDIT: answer from OCZ
Marten,
The EU model features an Active PFC, which is required for operation in Europe. Our standard model features a Passive-PFC, which is acceptable by US standards, but due to power requirements in Europe, an Active PFC (Power Factor Correction) is needed.

... i always thought active pfc is when your psu automatically recognizes if its plugged in a 110V or 230V power network
thats an added benifit, yes..
Found this (rather large) article over at xbit labs and awoke my concerns about passive PFC and my "Greek" OCZ.
http://www.xbitlabs.com/articles/oth...thodology.html
It seems passive PFC is "closer" to no PFC!! I am only interested in electricity bills... Looks like I'll try and sell my 520 for a EU unit...
[@ss kissing:ON] Any chance those kind gents from OCZ are going to agree on a switch?? :) [@ss kissing:OFF]
If you want to keep your power bill down go for a dothan. PFC does not make a significant difference.
First of all greetings to all this is after all my first post.Quote:

Well i was searching the net for a 600 powerstream and noticed too the eu version so i did a little search and came up with this

A quote:
Why Active PFC better than Passive PFC?
1. Active PFC improves Power Factor to more than 95% , which surpasses the 75%PF with Passive PFC solution. Thus Active PFC is more energy saving than Passive PFC.
2. Lighter equipment will be the trend for all 3C products and PSU as well. Passive PFC PSU adopts cumbersome components which make it much heavier than an Active PFC PSU.
Benefits of Active PFC:
Large buffer to EN harmonics requirement to ensure compliance.
Opportunity for future cost decreases as ICs requirement volumes increase.
Low risk in terms of material shortage.
A more "professional" solution than Passive one.
Full range feature comes with less cost.
Perfect power factor approach 1 for power utilization. (Environment friendly)
Better competition when power goes up was the trend of CPU's requirement.
Negatives of Passive PFC:
Mass production of inductor must be accurate due to small buffer to EN harmonics limit.
Heavy weight that might create problems during transport. (Vibration & shock)
Possible shortage of ferrite material.
Vibration noise if structure is not fixed correctly.
Poor competition (cost and performance) when power up to 300W or more.
Hope i helped :)
I just got my OCZ PS 520W today. And it had 2x12v and one 6pin PCIe connector. And it was the same on my friends 420W. Seems like there is a new rev. out now.
