I was wondering whether it seriously is as good as they are claiming it to be since I never thought an OCZ PSU would do this well.

Also how good are the OCZ Z series compared to the ZX series?

OCZ can make a pretty good power supply. Depends on what model and who made it. But they do make some mediocre units too.

The Z is a older model made by Highpower. The ZX is a newer model made by FSP. The ZX seems to test alittle better.
 
I reckon you need to update the recommended PSU list, and put it in some sort of order, be it wattage or price.

There are so many excellent units being missed out on in favour of some which, when you look at the prices, aren't worth it compared to what else you can get.

the rest of it seems pretty solid, good job :good:

But FSP isin't that great,right???
I thought FSP at max was mediocre.
So how can it make a good PSU for OCZ :confused:

If you noticed I said they can make a (pretty good) one. There are alot better power power supplies in the 1000W range.
 
Thanks everyone. I guess I have some stuff to do over the weekend now ;) I suppose I'll organise them into wattage range or brands. The OCZ PSU you linked is alright. FSP is not bad, but there are better units out there. I wouldn't hesitate to use one.
 
I think really we still need to add the differences betewen ATX standards and how that effects 'multi' rail PSU amperage distribution. I mean something with 2 x 12 V rail at 20A with ATX 1x standards can only provide 20A to the GPU minus the CPU. Not enough.
 
your ideas plzz

my config is :

Gigabyte GA-970A-UD3

amd phenom II X6 1090t BE

Sapphire radeon hd 5850 xtreme

corsair 2*2 Gb

cooler master hyper 212 plus

samsung 1 to HDD

My Qus :

Did a "be quiet pure power l7 530w" PSU would be enough to run my pc at max load ? ( even after overclocking ) ?

Help me plz :)
 
You should also list that the power requirements you listed are for reference cards, not OC'ed one's. Ive seen a vid on youtube that had 2x6990's OC'ed that was pulling alittle over a 1000w(you have it at 850w).

Noted. But as for 6990's pulling 1000W, that must include the rest of the system with a hefty overclock in everything, otherwise that's just unbelievable.
 
hey you posted these....


9600GT.................................400W .........................28A
but i ran that card at 17 amps and with a 250 watt psu??? and now i'm buying a gtx 460 1gb can you please recommended a psu which would allow some overclocking.....
i have


Intel C2D E7200 OCed @ 3.60 ghz,1hdd,1dvdcdrw drive,one 12v fan and a gts 250 on a 450 watt psu giving 21 amps on +12v rail.Is that enough or should i buy a new one.

You're a fool if you ran a 9600GT on a 250W PSU. I also very much doubt a 250W PSU has 17A on the 12V rail. It certainly couldn't provide that.

A GTX 460 OCd requires at least 26A on the 12V rail, I would rather see 500W quality PSU from something like Corsair.
 
I'll have to update this with the Radeon 7000 series soon. And the next Nvidia ones.

Guys, I'm quite busy, and I will be traveling to visit my grandfather who is not very well. It might be a while before I get a chance to properly do this. If anyone feels up to the challenge of adding the latest cards, give it a shot and ask an admin to add them, and refer them to this post. Thanks guys.
 
I'm still having issues with graphical crashes both in and out of game. Card was replaced by XFX, my mobo is fine, and so is my RAM. I'm wondering if I have an underpowered PSU. All specs are in my sig (running 3 HDD's though). I'm starting to think it's my PSU. Thought? I don't understand electronics very much, but from what I'm gathering from what I read I have a general idea.

So what kind of problems are you getting? That PSU is rather solid, though. How long have you had it?
 
I've had it for maybe 6 months. I get random video driver crashes (that can recover) and other video crashes that don't recover and reboot the system.

I had the same issue with my other 750W Antec PSU; that's why I got this one.
 
Sometimes my games freeze up, the audio screeches, artifacts appear, the game crashes, and everything artifacts until I reboot my PC. It's weird. Anyway, done the usual driver update and so on?
