Just trying to gather opinions. I am looking for a high output PSU, and after talking people seem to like these two, and a few others, but I like these.
 
I'd choose the OCZ Powerstream over the Enermax personally.

Enermax = 5% load regulation
OCZ Powerstream = 1% load regulation

At this point I should note that the OCZ Modstream is not in the same class as
the Powerstream.

Can you tell me why you would choose the OCZ? I am seeing it has a better amperage per 12V rail which is good.
 
I've read some nasty things about the older OCZ powersupplies... not sure if the new ones are up to par or not... personally I like Antec. They are IMO, the best there is.

The tighter load regulation. Also from reading personal experiences in the OCing forums.

An interesting feat that it may claim. Especially interesting since the units test close to 2% http://www.silentpcreview.com/article173-page4.html and the Topower P6 is not either http://www.dansdata.com/top686p6.htm which the OCZ is based on. ;)

Already knew that. Was quoting the manufacture's specs which can't always be trusted as
you elequantly pointed out. Anyway, 2% is still better than most units is it not? :cool:

Dangerous thing using manufacturer specs on power supplies. Power supplies are the wild wild west of computer parts. One 480w powersupply often is not comparable to a number of other 480w's as the were rated at largely irrelevant operating temperatures. The same goes for regulation. One rebrand of a PSU may claim one regulation but if it is different from the base model of teh actual manufacturer it is safe to assume someone "massaged" the numbers. 2% is better than most but it is dissapointing to see it miss advertised on what is an excellent PSU. It would be so much more expected to see the misadvertisement on a Powmax or some such. Just disapointing on a good supply.
 
You are right of course. Brand & build quality is paramount. Sadly the manufactuer's specs
are often all we have to go on unless someone provides a comprehensive review with an O-scope.

I think we can all agree the manufactuer's specs are about useless unless they provide other
info like what temp the ratings are taken etc.
That's why we see some cheap generic 550w PSU dropping below 200w when they reach
operating temp. And also why I've had 300w Fortron outperform generic 550w PSU in the exact same set up.
 
well if we are offtopic and making recommendations
My opinion is well known :p


on topic
the OCZ
while their specs arent accurate they are tighter
unfortunately neither supply has any published crossload chart
but your config is likely to fall into its sweet spot for load regulation with either supply given a halfway decent modern config,
which Im assuming since you seem to think you need alot of power

of course if its for the configs in your sig you wouldnt want either of those
 
Looks like Ice voted for the OCZ. I don't have enough knowledge about these two PSUs, so I didn't vote (and I don't really worry about new PSUs since I'm still stuck in the 2003 era pre-ATX12 2.0 ;) )
 
Its for a new system I am putting together. I was trying to get an X2 system put together for under $1k. But it aint going to happen.

Seasonic is worse that OCZ or Enermax. That is unless you like the 12v rail to melt to your ATI 9800PRO... TWICE.

Same thing happened to a buddy of mine.

ontopic OCZ
off PCP&C

though what the real differences are between the Enermax and OCZ would be for a given crossload is unknown

So, you saw two Seasonic PSU have problems and they are ALL no good now?

I am all for using PCP&C, have one myself. But if you think they are totally immune
from defects you are deluded.
 
true every PSU make eventually takes something down
some just make a habit of it, if that seasonic melted to the card
there was one hell of alot of resistance in the connection
the by product of which was heat

I guess either a problem with the connector on the card since it happened twice
or just a poor connection repeated twice or an over matched PSU
 
when i was searching for my psu i also narrowed it down to those 2.. i went with the enermax because at the time it was SLi certified (im not sure if the powerstream is now, probably is) im sure it fuels enough power for my pc and the fans on it are just about impossible to hear

i think those 2 psus are pretty much equal.. a better one would probably be the pc 510 if ur willing to spend more. if u look around u can get the enermax for ~130

The Powerstreams aren't SLI certified, even the 600W model isn't.
 
That really doesnt matter unless you see games coming out in the next few years that are SLI only games, cause then i would be screwed cause the MB I was looking at isn't an SLI MB.

Like I said I had a grand to put together a X2 system, not happening since the damn price wont go down.

Here is what I was looking at:
Asus A8V Deluxe v2.0
2GB Corsair PC3200 ValueRam (Not overclocking so it should work just fine, right?)
7800GTX (was looking at XFX cause they are good & cheap)
DVDR Lite-On
PSU (the question at hand)
AMDx2 4400+ (Too damn expensive right now)

The 7800GTX comes in AGP? Because that's what the A8V Deluxe offers.
 
Well, I'll be damned. I swore I checked and that board came with PCI-E, crap. Now I need another motherboard, and that one was only $115. DOH! Thanks for pointing that out, I would have been screwed.

Not the S12's. They're not as efficient as the SS series. They're also sly about it by saying "up to 80% efficiency" instead of saying "> 70% efficiency" like everyone else. The efficiency of the S12 is actually no better than that of an Enermax.

Which is why I chose Enermax. It's quieter and has better efficiency than OCZ. ;)

well heres the S12 series (500W & 600W) and their efficiency levels: http://www.silentpcreview.com/article247-page4.html

thats some darn high efficiency. :cool:
 
have a feeling jonnyGURU was suffering from caffine deprivation when he posted that?

the S12's are 80 Plus certified supplies
which has been borne out by independent testing as you so kindly linked.

Ive always found peak efficiency ratings just another deceptive marketing tool
if you happen to be outside the sweet spot for the effciency which more than likely is the majority of the time considering how little power is really drawn unless your constantly folding

which is why I think the S12's are really good as the band of effciency is quite wide and why I really appreciate the way Mike Chin at SPCR puts his effciency tables together

jonny you know something I dont?
(well Im sure you do :p I mean about the S-12's efficiency)
 
what is the average power draw of a high performance pc nowadays? (AMD A64, DFI SLI mobo, 1x6800GT, 1 SATA HDD, 2 Drives, 1 floppy, 3 silent fans, 1 cpu cooler, 1 gpu cooler is what im getting at)

im too lazy to bother to count wattage ratings :p

but what do you guys think youre drawing on average?

No. I thought just the SS series was part of the 80plus club.

The S12 430W I reviewed documents "up to 80% efficiency" and I was only able to get 74%@463.5W, 75%@453W and 76%@407W: http://www.slcentral.com/dual-12v-psu-shootout/

Now if that's not true with the 500W and 600W, my apologies for my outburst. I haven't had the pleasure of testing the S12 500 or 600W models.
 
greatly depends on exactly what your background process pattern is and what your "typical" foreground aps are

on the one hand surfing, word processing and IM dont hit the CPU\GPU hard, say near idle below

on the other multitasking with encoding + surfing listening to music ect can be up there

you can add an additional 24W DC to any of those just by making the Optical drive spinup and overcome inertial at the right time,
or should I say the wrong time? :p
 
o wow. i was expecting much higher values. so gaming w/ a state-of-the-art system will probably reach a max of 350W while gaming...

so i might as well save myself some money and just get the s12-500.... save on heat and power too. awesome. thanks guys! and sorry for taking the thread a little off-topic.. :eek:

anyways, back to the OCZ vs. Enermax flame war ;)


EDIT: probably not even 350W.... probably not even close :eek:

hmmmm Mike also covered the 430 and came up with slightly different numbers
http://www.silentpcreview.com/article226-page4.html
EFFICIENCY: It's clear that that the efficiency curves of the two samples are not quite the same. The new sample starts a bit lower, catches up at about half power load, then stays at a bit higher efficiency out to max power. The difference could be attributed to the new Japanese aluminum electrolytic capacitors or to increased airflow from the new fan; it is also small enough that sample variance and tolerances within SPCR's testing procedures could be suspected. In any case, it's a negligible difference, especially in actual use. (The actually wattage differences are mostly <5W AC.)

but like you he found it wasnt an 80 plus supply
I forgot about that review :rolleyes:

the 500 & 600 are 80 Plus certified, guess its too easy to just lump all the S-12's together when they dont actually have identical attributes (something we both did :p )

3 things you need to consider

1. temperature, supplies are rated at different temperatures, some as low as 21C, the Seasonics at 40C, PCP&C at 50C. 40 to 50C is a reasonable temperature to expect inside a PSU that is exhausting the case and CPU heatsink., As the tempurature increases the PSU capacity decreases, its known as a derating curve, and can wack off a third of your capacity if the supply was rated at 21C.

2. those are "typical" numbers, not worsecase, to figure out worse case runtime senerios generally you assign full 100% values to the CPU, MOBO, GPU and 25% values to anything that spins. If its a storage box, you also figure a seperate spinup worse case (drives fans ect need their full rated draw to overcome inertia and then drop to about a quarter of that) to do either see > http://hardforum.com/showthread.php?t=844691

3. where is the capacity in question and this is the most important part
many supplies have "extra" capacity that is simply unavailable in any single configuration for backward compatibility, thus they have monster amps on both the +3.3V\+5V rail and the +12V rail(s) artificially pumping up thier wattage, the CPU switched from the (typically) combined +3.3\5V rail to the +12V
newer rigs needing even more capacity +12V as PCI-E is all +12V and of course fans, drives and some PCI cards have always employed the +12V. So you have to determine if a given PSU has the capacity your particular config requires on a given rail for brownie points you figure your crossload worsecase and if you can compare that to the crossload profile of a given supply to determine your likely rail stability, otherwise you look at other competant reviews and guess what your crossload might be like compared to thier testing proceedure


Thus total wattage is an extremely poor indicator of the suitability of a supply


you can get very lean in running a given config, and that is largely what SPCR as all about
but your flexibility can become seriously hampered, if your in pursuit of a silent rig thats a secondary consideration, but in here we are more upgrade monsters and have traditionally viewed PSUs as infrastructure investments. If you can buy a new supply to match to each config and upgrade, you can get very lean, if you want it to last through a few upgrade cycles extra capacity doesnt hurt much except the sound level and thermal solution (typically added inefficiency being further outside the efficiency sweetspot)
 
bump for extensive editing

but yeh the S12-500 will do ya for a modern config easily
but likely not a dual core w\ SLi PCI-E 150W or some number of extra HDDs
nowing where you are and where you can go keeps you from having unwelcomed suprises ;)
 
His numbers are still way better than mine. Do we know if Mike of SPCR is in the US or not? I can't remember.

If he's using 220V, the higher voltage, lower amperage can actually contribute to a cooler running power supply and therefore better efficiency.

That and I'm in Florida, so my ambient temps are 77 degrees minimum, which certainly doesn't help matters. ;)
 
so are you saying i might as well spend the extra 15$, get the s12-600, and pretty much be future proof?
 
well its $15
as far as "future proof" goes it buys you a little extra space but not necesssarilly all you need
its largely based on what you think you might want to do with the supply today and 5 years from now too if your running old rigs like I do (Dedicated NAS for instance)

what is going to happen to computing that far out and its power requiremnents isnt really known, the historical curve we have been seeing cant be maintained indefinately
for $15 you might be a little more relevant if you think your going dual core and dual SLi with the new 150W PCI-E (doubling current 75W spec), it also might hold a higher resell value.

You certainly don't "need" it, and you may or maynot need it in future
(you might adopt a config where its again overlkill or one that blows right past it)

the only supply I'll call "future proof" is the PCP&C 850SSI and thats $400 some odd dollars :eek: and its really for serious workstations, even servers with a ton of storage cant start to use all that power, but dual PCI-E 150 watt cards, dual dual core proocessors and a massive RAID can
