OCZ ZX1250W... Keep it or Sell it?

[vollman1]

I am receiving a ZX1250W from OCZ as a replacement for a ZX1000W that had coil whine.

The 1000W was priced too good to pass up, but is more power than I need.

So, should I keep the 1250 or sell it and buy a smaller PSU?

My system specs are:

i5 2500k OC to 4.8GHz @1.36V
P8P67 WS Revolution
8GB 1600 RAM
2x Asus HD6950 DCUII 2GB OC to 940/1350 @ 1.2V in Xfire

Thanks for any advice.

The ZX1250 is a $230 power supply, I'd sell it. Your system would run on 750W, preferably 850W. XFX 850W XXX $120 AR

If you need a $200 1200W power supply later, it's going to be for a system that is a hell of a lot more expensive than what you have now, and it won't be a problem to incorporate a new PSU into that build.

Sell it, i bet you could run on a 650w, but i would get a 750w so you can overclovk and have room to grow later.

650W would be kinda tight, he's running a highly overclocked system. That's 150W for the CPU, 200W for each GPU at peak, could be even more. Looking at 600W full system load.

Thanks.

I do think that I will try to sell the 1250 and maybe get into an 850.

Thanks for the advice.

Antec Truepower 750. Cleanest consumer power supplies out there.

I'd keep it. PSU prices don't come down that quickly, and

1. OCZ is probably not the best brand for PSUs though I am not sure on this. This would be as safe as a Corsair 900-1000 watts I guess, not sure on this though.

2. If this is equal to a Corsair 1250, it will last a good 5 years or so. Why waste the investment?

^why waste a 230 dollar psu when youre not using it all?
if its not the best brand, why not just sell it and buy a quality 700 watt psu?

The OCZ ZX1250W is manufactured by Great Wall. Its actually a Sparkle Gold Class 1250w. Its actually a good brand and will certainly pull its rated wattage. I would keep it if you will utilize the wattage in the future.

EDIT: Reading further it actually does Bronze efficency at 10% load which is good for a 1200w unit. Also beat the AX1200 in ripple suppression.

 

[aaksheytalwar]

If you sell this and buy a 850 watts unit now and buy this 3 years in the future , again, then you will end up spending more money in total than if you just keep this with you. This ensures that you can even do 7970 CF or even Tri Fire/use as many HDDs as you want/water cool etc and do all this for the next 3-5 years without any sweat. I would keep it for peace of mind.

Very few people actually NEED a PSU that puts out more than 850 watts. Unless you plan on doing 3 cards in the future, you won't need this. You should already know whether you are likely to do something like that in the future.

 

[SZLiao214]

I would probably sell it and get something closer to 850-1000 if you can make a good profit off of it.

Still more then you need but i like a lot of lee way.

While true, ripple suppression isn't typically considered the most important metric for a power supply. The general consensus of the most important metric in a power supply's performance is voltage regulation, and this is where the Corsair slams the OCZ on the floor.


The Corsair manages 1% regulation of the +12V rail at full load and just outside 1% on the minor rails. Contrast that to the OCZ that barely manages 2% regulation on the +12V rail and 3% to 3.5% on the minor rails....not so great. Not horrible and within the ATX spec, but if you're paying for premium performance, you're certainly not getting it from the OCZ unit, esp. contrasted with the industry leaders like Seasonic, Corsair, Antec, etc.


And this doesn't even address the OCZ's worse performance in transient overshoot performance...again, not horrible but certainly not up to the standard of the leaders like Seasonic, Corsair, et al.


Ripple suppression is all well and good, but once you achieve less than half of ATX spec on full load, anything else is just gravy and really doesn't do much to help. Voltage regulation, on the other hand, can have real impact on system stability, esp. with heavy overclocking, gaming, etc.

Vote to sell and pick up a solid 850 watt psu.

Sell it. You don't even need a 1250w PSU for gaming rig. Just sell the PSU and get a 650w one. Then use the extra cash to upgrade your rig.

 

[vollman1]

Thanks for all of the input. I will try to sell locally and get a smaller, better quality PSU.

I appreciate the help on this
