I agree aside from the noise it looks like a great PSU. Typically I only go to Seasonic and Forton-Source for my PSU needs, looks like I can add Enhance to that list now that I know you can buy them.

Antec SmartPower 2.0 500W working great over here and it's very inexpensive & quiet. Plus it is modular and has a whole bunch of cables (including two for PCI-E).

link to current issues? or is this still the original true line that isn't made anymore?

If you could provide a link to some current issues or at least to the forums where you read about them, I'd really appreciate it.

You're right, I do know that you know he doesn?t need 600 watts, but still the 600 watt recommendation? I guess I don't see the point of all these 500-600 watt recommendations when it's practically impossible to build a system to approach such high power levels. My point is there are already too many misconceptions floating around regarding power requirements, we don't really need anymore....

The confusion starts with standards in rating power supplies or the lack of. Read the psychotic diatribe on heating and power issues at the end of Luckyboy's Guide For Complete Users for just a few problems with ratings standards, much less every factor that adds to the confusion.

Then there's something I like to call "head room". It is having extra capacity so that all legs or plugs or outlets of power can be assuered to deliver what is not just neded, but desired at all times regardless of this or that problem. With as far as we are pushing silicon these days and the power demands that result from it, getting cheap about power issues is foolish at best.

Headroom is one then there is buying twice the power you can realistically use. Which is what a 600 watt PSU would equate to for the OP. Nowhere did I say anything about going "cheap"; find out how much power you need, factor in some headroom, then purchase the best PSU your budget will allow. You would be much better off with a top quality 450-500 watt PSU then a mediocre 600 watt unit.

Well, all I can say is that even if you choose a power supply that only gets half its' capacity used, it is still working at 50%. The problem is, even if by all your numbers, you have that, you still don't end up with that in the reasl world over time due to standards not being the same and power supplies degrading over time.

yes, they don't like pcp&c caps either :Q

Nice try...but I have seen no posts in other forums and such about PC Power & Cooling PSU`s having CAP problems...
enlighten those of us who own them...
Ohh...I get it your just angry because I am always bringing in the Antec CAP issue.....lolol

Badcaps is a nice website..been there done alot of reading.
I usually get my info from other forums as well as anand`s forums...
All goos stuff.

I have even been to the bad caps website....
Again the saying goes the track record for alot of PSU`s including Zippy,PC Power & Cooling and Fortraon and a few others is exemplory....you can`t go wrong based on there track record..

Yet....shall we look at Antec`s track record......lolol

My point is a simple one; 500-600 watt PSUs are almost never required. You always better off with a quality 400-450 watt PSU then a cheap 500+ one.

Having more power then you need is ok as long as you aren't sacrificing quality for quantity. I think we agree on that aspect right?

Nope haven?t abandoned it. I haven?t decided what I?m going to go with but thank you all for the helpful information. I?ll post back when I?m closer to buying something. I haven?t bought the 2nd card yet due to the lack of availability.

:roll:

no where did i say that i've seen bad caps on pcp&c units on other forums. i said that badcaps doesn't like the caps pcp&c uses. or fortron. or seasonic. or tagan. or...the list goes on until you hit zippy iirc.

so basically i was saying take badcaps.com fwiw.

just because i bring up your beloved pcp&c doesn't mean i'm bad mouthing it. unlike your previous favorite psu (what was it, okia or something :p), i like pcp&c.

as for the antec cap issue, all i asked was if it was the original true line you're referring to (again). you don't anger me (although i know thats the goal of 90% of your posts on AT, to instigate others), its just that you have nothing to offer, as usual.

Actually most of the time when I post its for the same reasons you do to add my opinion...
Yet.....what people forget about alot of these companies that are listed in bad caps as you mentioned in your brief list.. almost no company takes the PSU as it is and then just adds there logos etc and sells it...

Even though they are lsited or shall we say the company that these brands allegedly buy there CAPs from....as was stated by a person named Oklahoma-- I quote--I too vote Zippy... I've seen them using Chemicon as well, and the odd Capxon for smaller caps. However, the PC P&C Turbocool units are still very, very good - I hardly ever see complaints of them failing. The Silencers are all Seasonic for the moment.

I know for a fact that several brands including my beloved PC Power & Cooling add there own heavy duty CAPs and other items as well as benching them before selling them.

So thx for the explanation.

well, clearly they aren't all just getting their cap info from vendors lists, if thats what you're trying to say.. they're opening up the psu and seeing whats inside, hence all the pics :p

and oklahoma wolf is just saying he isn't seeing alot of failure. nor have i. doesn't change my original remark

anyway, this thread is dead, at least to me.

have a nice day :p

15c in addition to ambient you mean??? That equates to an extremely restrictive case.

your opinion???

I don`t think this is talking about the case...
Its talking about at what temp PSU companies rate there products....

and when I buy a PSU any PSU that one fact alone says a whole lot about the quality and what the life of the PSU will be....correct me if I am wrong..
After all I am always learning! :)

Yet what concerns me is that alot of companies don not even list even list or if they do its buried somewhere at what temps there PSU are rated becuase we both know that if the air going to the power supply is going to be 25 degrees Celsius in the real world because with a 15-degree buildup inside the machine first, before the air reaches the power supply, that means that the room temperature would have to be 10 degrees C. Now you?re talking about it being in the 50s Fahrenheit.

Anyways all good stuff!!

Not in my case. I have a aerocool aero engine with 3 120mm fans and the original 140 in the front and my case temps are never 1 degree above room temp.;)

LuckyBoy1 Scroll down and look at this graph:

http://www.silentpcreview.com/article28-page4.html

Most powersupplys have an efficiency curve like that that peaks somewhere in the middle like that. At lower watts, however, the large power supplies are more inefficient. Inefficiency ~= heat. (is proportional to). So, the large ones are actually working harder, drawing more watts from the wall, putting out more heat, to deliever the same wattage.

Bigger is not always better.

Actually thats not entirely true...
that graph is NOT true of all brands...
There are other variables top consider too...
Would you rather have a PSU whose rated 90% efficient but was rated at 25c??
Or a PSU whose 70% efficent but who PSU was rated for 50c ?

See my point??

I realize that. My comment was strictly aimed at the fact that you think case air is warmed 15c, above ambient, BEFORE it makes it to a PSU. Did I understand you correctly?

My opinion on PSU's? Review the prospective unit well, stick with brand names and don't be cheap. Did I miss anything? :)
