Need a new PSU ?

[minaelromany]

Hi guys

I've had my rig for a year now and everything was running well

A month or two ago I had to back my OC a little from that in my sig because my system was not stable at all. First I suspected the summer temps (which is hell hot here in Egypt and I don't have an AC yet!)
Yestreday I bought the Sapphire TOXIC HD4890 card and CFed it to my HD4870 512MB (Stupid , yes I know) Anyway I got a nice OC with the card but didn't play with it enough
I wanted to check my PSU rails to see whether everything is ok or not and I've noticed that the 3.3v Rail outputs 3.14v , 5v Rail outputs 4.97v and 12v Rail outputs 11.87v Idle , at load the 12v Rail went down to 11.76v

Is that bad ?

Is it the cause for the OC that worked in the past not working now with my CPU/MOBO/RAM ?

Will I get nicer OC with my TOXIC if I upgraded the PSU ?

The PSU I currently have is HEC Zephyr 750 Watt and I am considering 3 PSUs in the same price range (same price here in Egypt I mean) :

1-Antec TPQ 850 Watt

2-HEC Cougar 1000Watt

3-HEC Cougar 1200Watt

I want to be covered by power so when I want to put 2 HD4870X2 cards (or 2 of the upcoming HD5870X2) I want it to be perfectly stable

Waiting for your Opinions

I have this same psu...

Its internals are actually the same as the 650W version. Its a...midrange psu.

Not bad, but not good.

Did you use software or a DMM? Software won't be accurate. 3.14V for the 3.3V is just of out spec. The other rails are fine. But as mentioned, it all depends on what you're reading voltages with.

[minaelromany]

I know that the PSU I currently have is mid range and that is why I wanted a High Quality (future-proof) one

I read the Voltages from BIOS as well as Everest, I don't have fancy equipment

[370forlife]

All you need is a simple DMM.

[minaelromany]

You mean a Digital Multimeter ?

I don't have one and I don't know how to use these things :D

I just want to get a better higher quality PSU and have tochoose from those three

I have a friend who wants to buy my PSU for a good price, and that made me think about getting another one :)

[jonnyGURU]

You mean a Digital Multimeter ?

I don't have one and I don't know how to use these things :D

Understood. But likely false readings from the BIOS and Everest (both derived from the same source, so both equally as incorrect) are causing alarm.

DMM's are cheap and using a DMM to measure voltages is simple: http://www.bfgtech.com/bfgpower/troubleshooting.html#software

Of course, if you WANT to upgrade your PSU and someone's willing to buy your old one for a decent price, that's a whole other story.

I assume you're planning to buy a 30" monitor since quad-Crossfire is absolutely ridiculous overkill for a 22" monitor.

[minaelromany]

I will get a DMM tomorrow and see the voltages just to make sur that the friend who will get it will not get a faulty PSU

Is that HEC brand (Zehyr 750w specially) a good one in your opinion Jonny ?

I now have narrowed my choces to either Antec TPQ 850w (80+ Bronze) or HEC 1K (80+ Standard), which is better ?

I wanted the Corsair 850HX but it is not available here

I had a word that this bad boy would come to Egypt soon :

http://www.insidehw.com/images/stories/news/products/OCZ/OCZ_Z_1000W_Gold.jpg

Or the 850W Model but they may take sometime (I guess they are PCP&C )and I can't wait

@TheAnimal :

I am not planning on getting Quad-Fire setup for myself but I do alot of GPU testing and benching and 22" is really a waste of power here but I would do some 16X/24XCFAA to compensate for the lower rez :D

[Mantralord]

Do you actually use your system to play games or just run 3dmark all day?

[Hondacity]

pcp&c?

the zephyr's are so so...just good marketting on hec's part.
the antec tpq 850's are made by enhance...quite good..above average stuff

HAHA, PC Power and Cooling with a large fan? No the OCZ Z series....is OCZ, just like the label says.

I hope you aren't one of those people who actually thinks PC P&C actually makes power supplies (they are not an OEM manufacturer, they contract out with OEM manufactures to design and make their PSUs, just like Corsair and OCZ)

The OCZ Z series 1000W are made by Sirfa. I would wait for a decent review with ripple measurement...(I'm talking PC Perspective, jonnyguru.com or HardOCP) before I jumped on that.

The 1000W Sirfa build units reviewed here and at HardOCP in the past have been less than stellar.

The Antec is better, but I don't think I'd run 2x HD4870x2 with it. Only 64A on 12V and the GPUs will be using ~44A.

Found "a" review.
