Erm... the links in people's signatures. pkme2 is the only one who has recommended the PSU that, to my knowledge, actually owns one. How can you possibly recommend something with no experience? I am by no means trying to say the Seasonic is bad, but the GX is better.

As for happy, I don't envy his job either, but there's a reason why I post on DFI-Street and not Anandtech. His attitude is understandably testy at times, but just because you can't follow 11 rules isn't my problem. He owns the forum and is free to ban whomever he wants to.

One particular users experience with one particular PSU is just about meaningless. There are after all many people running happily with Aspire, Raidmax or even worse Deer or Powmax, that certainly doesn?t make them good PSUs.

The only way to obtain valuable information from one particular PSU sample is to test it to full load, only from that can anything useful be gathered.

PS.

If it makes you feel better I've built several machines with the S12, so I do have first hand experience.

 
LOL, how long have you been hanging around dfi.street? Often times it has nothing to do with following rules. Do you remember the Cold boot issue days 😛

And I'm not banned there or anything if thats what you're implying. (I can't tell if by saying "you have to" that you actually mean "one needs to"). It was a hugely helpful forum when I got my boards last year.

At any rate, I have a seasonic, not the 600, but I can attest to its quality and quietness, which in case you didn't notice was one of the OP's requirements before getting his rma replacements.

Jonnyguru has the 700gx and can attest to its quietness, or lack thereof.

So assuming both are of equal quality then the seasonic would be the choice, no?

I'm more concerned with how much the 12V jumped with just a minor drop in 3.3V and 5V load.

Fortuntaely, 5V loads are pretty static.. except for RAM, but the load isn't that great to begin with.

So crossloads are almost a non-issue, and probably isn't even worth mentioning. So if you don't mind the air raid siren for a fan, it's a pretty good unit.

Johnny....the fan is not supposed to be loud.....if you can hear it over an XP-90 with a Sanyo or similar fan.....email me so we can get it replaced.

All 3 of mine...are near silent.

Thanks....email in Sig.

There might be something up w/ the fan. I'm willing to believe that. I mean... the pitch is almost exactly that of the "this is a test of the National Broadcasting System... this is only a test" when the PSU is under load, it's almost humorous.

I'll drop you an email in a couple days.

Right. I read that. Like I said, "too bad we don't know what the voltages were for each rail on each load test."

-/+ 2% is good, but they must have the information. They have the load tester, do they not know what the load is on each rail? They obviously know what the voltage is on each rail during each load test. Why do they not detail it?


 
Yeah, fair enough criticism of that particular review. The article itself is over a year old and, I'm guessing, they probably felt like a quick commentary was enough at that point in time. More recent reviews on power supplies by the same site include individual rail data on a chart.

For the sake simplicity most likely.

Later tests do document the loads placed on each individual rail as seen in this Enermax review.

But it's probably a good idea to have a backup psu..

I found this pic of the OCZ unit, looks sort of skimpy..

Anyone have a pic of the 600w Seasonic or a review ?

I just installed a OCZ GameXStream 700W PSU in my nephews rigg.
http://www.neoseeker.com/Articles/Hardware/Reviews/OCZ_GXS_700W_PSU/3.html

He loves the PSU.

But let me say its one of the lightest weighing PSU`s I have ever held in my hands.
Its as light as my OKIA 450 that i have around here somewhere.

So maybe the wave of the future is to design highly efficient lightweight PSU`s.

Hm, if you are talking about support, OCZ gets the win. Also, I have yet to hear anything bad about this psu, aside from the crossloading (a generally NON-issue at that now). 700 watts.... that's an aweful lot of stable power in a compact, sexy unit. Mine arrives Tuesday, I can't wait!

OCZ was unable to swap out my fan because I opened up the unit... even there's no "warranty void" sticker. But that's neither here nor there. Nobody should have a warranty if they open up their PSU. I was just hoping for a replacement fan. I'll simply mention in the review that the fan was unusually loud, but due to a number of first hand reports on the web, I have to conclude that it's an isolated incident.

As for the "performance," we'll see. I've got my heat chamber built and will have the second load tester hooked up by next weekend so I can really test it out. I'll also have the USB-Instruments Stingray hooked up so we can see how stable those voltages really are. 😉

One possiblity is that all/most of the users on the web are drawing around 200W from the PSU or less, which means they are still around the load test 1 point when the fan is quiet. Since the power draw is small the fan doesn't ramp up and so doesn't get loud.

Or it could be a dodgy fan. 😀
 
I'm thinking dodgy fan, because even idle to low load, there's still a weird whistle... just not as loud. It's just not a normal sound, you know? It's like some guy sitting next to you on a park bench with a deviated septum breathing through his nose. After about an hour of sitting next to him, you just want to beat the crap out of him.

Alot of people are concrned about the fact that PSU appears to have nothing inside.
In fact we have always heard that the heavier the better.
That PSU appears to be just the opposite..... alightweight PSU.
Only time will tell.

Yeah, i know the feeling... :|
 
I thought that the OCZ psu was a 600w, 700w max. If this is true then the tests are extremely impressive, if it's not true then it's still a great psu.

I'ver always used antec, but will get the ocz or seasonic (or something good) when i build my rig.

No. I think you're thinking of the Powerstream 600W. The GameXstream is 700W continuous, I'm sure.
 
I like xbitlabs reviews with their cross-loading and power regulation graph which is excellent imo because it shows whether the rails are regulated individually and how good regulation is throughout the whole range.

Given the very low 3.3/5v requirements of current typical pc's, I like to see how psu's really perform when the 12v rail(s) is maxed out while the 3.3/5v load remain low.

The more I've learned, the more I've realized Oleg likes drama.

Even a PC built with only one hard drive and one optical and one floppy, idle, is going to have a static 5V load of 4 to 5A. That's well above the minimum load requirements of most power supplies.

And keep in mind that a power supply taps it's 3.3V rail off of the 5V rail with a VR, so you can add whatever your 3.3V load is, times 3.3, divided by 5, to that number. So consider your RAM, PCI cards, whatever else you might have in your build.

I was "suckered" into doing crossload tests by someone who thought that Silverstone's 3A minimum 5V load requirement was unrealistic. I then found myself doing unrealistic high and low 3.3V+5V crossload tests on power supplies. What a mess. I was taking points away from power supplies that didn't deserve to be graded on that kind of curve.

And the FSP/OCZ 700 is one of them. There's no independent regulation whatsoever, but I'm sure FSP feels perfectly fine with that decision because of the way computers work today.

The only "realistic" crossload scenario is someone throwing an ATX12V power supply in an old ATX board where the CPU's voltage is regulated off of the 5V rail. But seriously, if someone is still using a motherboard w/o a P4 2x2 connector and hooks up an ATX12V power supply, they deserve to have their stuff blow up. 😉

Well said :thumbsup:
I have an x1800xt, abit at8 32x, an OCed opty 165, 3 hdds, 2 optical drives, 2 sticks of ram @2.8v, 10,000,000,000,000 fans/cathodes/led's, 6 usb devices, an x-fi plat, and aftermarket coolers on everything that has a cooler. When this PSU came along, I about shat myself.... I need the power and I'm banking on this being at least as good as the 600w version. I mean, I'm upgrading from an Ultra X-Finity budget 500w psu and my cpu hates it when i try to overclock... the rails skip around too much
