OCZ 700w or Seasonic 600w ?

I hope the OCZ 700W fixes that problem. Not sure if your problem is actually the PSU, though. I've put an X-Finity 500W and 600W on the load tester w/ the oscope on it and so far it's far from the worst. I'm putting my BFG 650W review up tommorow and by far THAT is the worst voltages I've seen for a "high end" PSU in a while. Haven't finished the OCZ test yet because I've upgraded my second load tester and won't have it up on the bench for two weeks. To effectively test it, I want to have a seperate load on each 12V rail. The way I did the above test is to not load 12V4 and to split the 12V2 and 3 load across one. Effective, but not the data I want to base a review on.

I'll try to have some screen shots up by tomorrow night so you can see the comparison.

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. 😉

What do you mean by 'Oleg loves drama'?
From the graphs I've seen, the psu's with independant regulation have much better regulation with the 3.3v/5v rails at typical loads when the load on the 12v rail is high.
 
And that is a correct statement. But to load the 3.3V and 5V really high or the 3.3V and 5V really low to start with is not necessary.

A PSU without independent regulation certainly is capable of maintaining tight voltages even if the 12V rail is loaded all of the way and the 3.3V and 5V are AT A REASONABLE LOAD.

And independent regulation doesn't always result in perfect crossload results.

I know you're ready to bury the OCZ 700W already. Let's wait and see what it looks like on the load tests and the O-scope.

But for the record, I'm not doing any more crossload tests.

And as for my statement about Oleg: I'm sure he's a nice guy, but sometimes I read his stuff and see things that are said just for "dramatic effect." I also see him make "judgements" on how or why something is made a certain way and when when you try to point out something different to him, based on fact or whatever, then he takes offense and says something along the lines of "I've tested dozens of power supplies." I'm not saying he doesn't know what he's doing, but if you don't know something FOR A FACT, don't spew out made up stuff just so you can make up word count.

Oh, I know this Ultra isn't bad, its a great PSU for 500 watts, the superior cabling and the price (50-70 bucks), i just need more power. I think I'm stressing this one too much when I overclock, just don't have enough watts...

Also, I must say that Ultra is coming up with their quality and their lifetime warranty... Compared to the X-Connect, X-Finity seems like it was made by a new company...
 
Make sure to let us know if the OCZ helps out with the overclocks or not. Could be good information for a lot of us.
 
What I meant was psu's with independant regulation have very good stability. The ones that don't typical have poorer stability where it matters - med->high on 12v rail, low on 3.3/5v rail. And those psus with independant regulation do have nicer rectangular looking crossloading graphs, at least the ones I remember looking at.

What do you mean by reasonable load? Xbit and Silentpc have already given the typical distribution of a pc's power consumption - less than 5A on 5V and less than 3A on 3.3V. So stability and crossloading tests above 50W on 3.3+5V is less important to the vast majority of people who don't have many drives or lots of pci devices.

I don't know what you mean by burying the ocz700W since I didn't say anything it and many people here think that they are a top quality brand.

It doesn't have independent voltage regulation. So by dismissing a power supply because it doesn't survive crossloading because it doesn't have independent regulation, by default you bury the OCZ 700W.

But enough about it. I don't want to talk about it anymore until I'm done with all of the tests using a proper load tester and inside the hot box.

I'm perfectly aware of what power supply you have:

http://www.slcentral.com/ultra-x-finity-500w-600w--flexforce-cables/

You assumed I hadn't reviewed them both? 😉

I WAS talking about yours when I said that the voltage regulation is actually better than both. But that's neither here nor there. Get the 700W OCZ and let us know if it fixes your overclock problem.

You must have gone to my rig link, either that or you are psychic 😉

Thanks for the link to the review, I did a lot of studying on this PSU before I bought it, but this mobo tends to be power hungry when you OC, don't ask me why, I couldn't tell you... But the best success comes from those with large HQ PSUs when overclocking with this picky motherboard.

I'm going to say "no."

Last email I got from you was last Thursday when you said you'd forward my email to marketing. I responded about the warranty sticker and had not heard back. 😉

I decided to go ahead and show the 12V rail's voltages with the 3.3V and 5V rails set very low (3A on the 3.3V and 4A on the 5V).

You'll see that the Silverstone passed with this condition and the BFG had to be cranked up to 5A on the 3.3V and 10A on the 5V (66.5W on the combined rail) in order to stabilize the 12V rails.

I'll go ahead and do this test from here on in.
 
I've had an OCZ 700W for about a month now and I am very happy with it!

It is very quiet, small, light, and the cable sleeving is very nice.

I wouldn't know how to measure voltage or any other readings but this baby is powering:

8 power hungry maxtor 300GB drivers
an X1900XTX
X2 4800+ @ 2700-2800mhz
7 Case fans
3 HD coolers
2 Fan controllers
And many USB devices (10 I think)
2 DVD Drives

Best thing is that this OCZ 700W PSU comes with a 3 year warranty and a full replacement RMA policy (They won't fix a damaged PSU, but instead it will be replaced with a new unit)
 
Bah, now I'm pissed..... F***ing Abit motherboard.... I'll never buy Abit again. Turns out my OC problems aren't due to the power supply, must be a manufacturing flaw in the north and south bridges.... The OCZ 700w works great, voltages aren't bouncing as much as my Ultra in a constant state. I'm just pissed off that this motherboard is total crap for overclocking... I want my MSI K8N Neo2 Platinum back.... even that old thing could achieve 2.8ghz on air with the same opty 165. Are there any Abit peope on these forums?

Bummer dude. Wish I had tips for you. Haven't used an Abit in years.

Start a new thread in the motherboard forums?
 
xtremesystems had a long running thread, got nowhere though. I'm 99.9% sure its a hardware fault with the motherboard, most likely a bad batch or something... PSU works great, now the true test will be how well my video card will be able to OC now...

Thats not unusual. Most companies will send you a new one rather than have you wait to have your unit repaired.
