OCZ PSU's = FAIL x3

I've had a OCZ Powersteam 520w running for about a couple of years now. It's been a awesome power supply. It runs my 4.4ghz C2D and 8800GTX great. Voltages are usually within a few hundredths of spec.

Naturally when I need another PSU I went with them again. My brother ended up with a 750w. but it didn't last more than a couple months. They were quick to replace it for him, but the replacement only lasted about the same period of time... He complained to them and they even upgraded him to a 1000w for free! Um, so yeah that's great, but............. it died AGAIN!!! They are going to replace it again, with a "new" 1010w unit, but he went out and picked up a 750w Ultra. He is planning on selling the replacement when he gets. I've always been happy with the OCZ product I've purchased, but are they going down the tubes? What will happen to PC P&C, didn't OCZ buy them? I always loved their power supplies too. Anyone else have this problem?

I'm sorry but I LOL'd at that part. OCZ is a bit more trust worthy than Ultra. I hope that Ultra 750W is a temp replacement considering the performance of this Ultra 750W PSU:

PC P&C quality is still just as high as ever. Yes OCZ did buy them. But I haven't seen any evidence of PC P&C quality lowering.

Is OCZ going down the tubes? It depends. I never really thought of OCZ as a high-end PSU maker. Or even a mid-range PSU maker.

Anyway, dude you just had really bad luck. Any one who has spent time in this part of the forum and seen my posts know that I am a major critic of OCZ PSUs. But in this case, even I have to say this: Just bad luck. OR maybe there is bad power where your bro lives?
 
Huh. I wonder if there is dirty power where your brother lives like Danny Bui says. OCZ doesn't particularly have strong PFC so a line with high and fluctuating reactive load or voltage sags may do something. Still, blowing out a 1000w PSU sounds a bit drastic.
 
Yeah.... he bought it without asking me.... He could have gotten a Corsair for a little more or even a lower wattage for less. His system would run great on their 450w even. It was the Ultra LSP 750w, I hope it works fine for his sake. Anything should be better than what has has gone through. I'm on the same power as him and it's seems to be clean and stable. It could be really bad lucky, maybe it payback for him wasting so much time playing MMOs (sorry mmo players).
 
A few years ago I have a ocz psu die on me after about a month of use. Their service was good and they sent me a more powerful upgrade within a few days. My thoughts after that and reading about similar cases with ocz psus was basically that ocz psus look nice but that's about where their quality ends.
 
I know OCZ PSUs aren't top-of-the-line, but having 3 of them fail one after the other is just bad luck.
 
The OCZ PowerStream 520W SLI was a GREAT PSU! Unfortunately some of the current OCZ PSU's are not quite as good, however OCZ is introducing a complete new line of PSU's to address this problem & their new 1000W has just received the first 80 PLUS Gold Certification for a 1KW unit ever issued.

New OCZ Z-Series 1KW 80 PLUS Gold Certified PSU

Dumping an OCZ for a Ultra is like jumping out of the frying pan & in to the fire!:rolleyes:

Hahaha, nice. I'll have to tell him that. If they send him that new model I might be able to convince to keep it. I hope to keep using this 520w as long as I can.

I actually had the 750w in my system and saw no benefit over my 520w. It's lucky I passed it off to him :p
 
I'm using a 600W OCZ gameXtreme power supply and it's been working fine... runs my Q6600@3.6 and an OCed GTX 260 without a problem. I want to upgrade my motherboard so I can physX on my 8800GT and run games on the GTX 275 I stepped up to.

It's running fine because you're only loading it to about 50-60% of its capacity.

Yes, but that's the idea, isn't it? Generally you want your peak power consumption (all HDs running, 4 cores processing, video card rendering) to maybe reach 75-80% of your power supply capacity. That way you don't overload and blow up your PC. There are power supplies that can be run at 40-50C, full load, but it's not recommended for anyone to do so. Usually peak efficiency is between 40-60% psu load anyway.

Over time the PSU will derate, and you'll end up experiencing problems even at lower wattage levels. That's one of the reasons why it's always ideal to purchase a PSU that does not exhibit power delivery issues anywhere within its output range. There are other reasons as well, but that's as detailed an explanation as I can give right now.

PSU's are most efficient when running at 40-60% of their total output. That can be said to be the 'sweet spot' of power supplies. 75-80% is getting close, but still well within spec and over 80% efficiency for some PSUs.
 
OCZ power supplys suck, check out their forums, Multiple units fail months after RMA. I recently RMA'd a 600 Stealthstream because it had a noisy fan and it was spaztic, in all their infinite wisdom they sent me the same make unit that had the same noisy fan. I did another RMA and received the PCP&C 750 Silencer.
 
I just RMAed an OCZ 800w Elite that died after a few months (~4) of 24.7 cruncher use. They sent me back a PC power and cooling 860w....it's a $250 psu. I haven't hooked it up yet...I'm debating on whether to keep it or sell it.
 
Turbo-Cools are solid, but then, you have to have your ear protectors ready before firing it up, lawl.

Bought an SXS 600W when it was 50% off here to have as an "emergency PSU", but it was defective out of the box, fan at full speed all the time and squealing coils under load. Same with RMAed PSU, so I just gave up on it and kicked it to the curb. Well, anyways, I gave it away for free, no point taking money for it.
 
All hardware dies, even the best. You can't say a brand sucks because you've had something die.
 
Well, I don't put much faith in their FSP Epsilon based units anyways. I've never had any of their Impervio or Sirtec units, but as far as Sirtec goes, IMO it's an even worse choice of OEM.
