Well...As some of you know, ive Grossly overestimated my current PSU! Its becoming unstable during a CPU Overclock adventure LOL! While some people dont think 11.88V is incredibly low, With this PSU I believe it is. Probably because its less than what it says it is. If it were a Corsair running slightly low, perhaps I wouldn't be quite so uncertain. But this is a brand(OCZ) thats not often talked about! It was a good buy, as well as WAY within the Spec I needed at the time. Now im not so certain. If you fine people like, you can TELL me to buy a paticular type of PSU. Im open to suggestion. I just want a PSU thats gonna perform without hitch! You know...the FREAK of the trade LOL! I dont wanna spend more than 200-300$
What do you think of this one? Ok, Ok, perhaps im becoming a BFG fanboy LOL!

But you gotta admit, this sucker has some serious power capability!!!

BFG don't actually make PSUs, they just buy other units (and not just OEMs, they're almost identical to retail ones too) and up the price. Please tell me you're joking about a 1200W PSU... haha.
To be honest, while the PSU is a possibility, I'm still not certain. It may simply be that the slightly lower output voltage means that Vdroop is slightly worse. If you raise the CPU voltage setting by maybe 0.02-0.03V you may well be able to compensate for it.

the BFG new PSUs are getting very good reviews.
Estuansis used a 600W OCZ tu run a heavily OCed Phenom II X4 CPU and 2 4870s aswell.
im suer the PSU is probably fine, how old is it kevin?

Hmmm...I may have deleted the email, regarding a reply post. Sorry about that.
I bought the supply back in december of last year. Its been in one other rig, for a short time.
You know...I just wanna be absolutely sure that im not hurting a component. 1200W means nothing to me, if it does indeed put out A LOT of amperage! 40amps per rail is quite impressive, IF thats not exaggerating LOL!
As a few of you already know, I may be looking into an alternative PSU for my Graphics card. -----> http://www.newegg.com/Product/ProductLis...ntary&x=22&y=31
I dont take coincidences lightly. Seeing the 12v Rail drop immediately after supplying the CPU with more voltage, tells me something is not right LOL! Surely by disconnecting the GPU, it will effect the PSU at least a little. I dont know much about PSU's, but if each Rail supplies amperage, from its own source, then perhaps it wont effect the CPU's Rail. That in itself is very curious. Guys, I dont wanna worry anymore that my equipment may be underpowered, or that my PSU may be stressed...
EDIT - Well...I think I have my answer. I just unplugged a HDD, and it effected it by .04 - .06V! Apparently, despite being separate rails, it WILL effect the other rails. Then why in the heck, dont they simply call it ONE 72Amp Rail!!!
LOL, you probably think im QUITE silly.

Independent GPU power supplies are rubbish, they are no more than the equivalent of cheap PSUs plugged in secondary to the main one, and cheap PSUs are bad. Just because your "700W" OCZ isn't powerful enough you're going overboard. Buy one of these and have done with it:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817379007
I've had 900W out of this briefly without any unusual activity. It runs a 700W system with ease, making no noise at all, and is very efficient. Your system as the signature specifies is about 280W.

i rma'ed one already because of the noise and the one i got does the same thing, not to mention it cost me almost 20$ to send it back to them
Please keep an open mind. I do not wish to anger anyone. :)
This makes me rather nervous. And its not an isolated incident. This review was for the 850W Zalman.
As you'll notice in the 300W versions title, its capable of running 295GTX in sli. NO NO, I dont believe that would hold up for long. Thats no doubt its PEAK PEAK! But im not looking at the 300W version, im interested in the 450W 85% efficiency version.

You do notice(Despite no one owning one long)that its receiving VERY good reviews.
Your probably right though *sigh* I simply can't afford much right now, and am entertaining the cheapest ideas that present themselves. I would much rather buy an EXTREMELY capable PSU, and be done with it. I would love a PSU that could run my setup without breaking a sweat!

With PSUs, you should know it's of paramount importance not to trust brands that have made bad products in the past. These products look similar bar the wattage, so if one is poorly made and overspec'ed, the higher wattage one is even more likely not to perform as indicated.

Any thoughts on the shrieking noise the Zalman makes?

I had this, or thought I had this, but it actually turned out to be my X48-DS5. In his case, I wouldn't mind betting it's the GPU.

All graphics cards make a shrieking noise to some extent, usually only under load (Hence me picking up on the 'any time my GTX260 is doing something' comment) - it's caused by the power regulation phase. This is also why my X48-DS5 did it. Gigabyte's E-series power regulators for their more expensive boards such as the EP45-UD3 series can sometimes do it too, but only if Loadline Calibration is enabled, or at least, much less so if it's disabled. Graphics cards are automatically loadline calibrated as far as I'm aware.

Mine does not make any audible shrieking sounds. The only thing audible is its fan. And I only hear it when I crank it up LOL!
Now im looking at an 850W Corsair. VERY good reviews, amperage looks good from a reputable manufacturer. The price makes it VERY tempting. I was looking at the 1000W, but this one looks like it would serve my needs almost easily. I HOPE!

The Corsair 850Ws are fine, but they are CWT units, of high quality, but not the excellent Seasonic standard that makes the 450VX,520HX,620HX and 650TX so popular. They are also non-modular, and much noisier than the Zalmans. They are also, pre-rebate at least, only $10 cheaper. Due to it sharing technology with a 1KW version, the ZM850-HP can go higher than its rated spec. The 850W TX is the end of the line for the standard CWT platform, it shares its design with 750W and 700W units so probably can't be pushed. The Zalman on top of all that is more efficient. Your call. The Corsair is still a good unit, but the Zalman is better in a large number of ways.
Of course, this is all over the top, as the 520W HX will power your PC perfectly.
Edit: The graphics noise is never loud, it's only audible in quiet systems. The average PC makes too much fan noise for it to be noticeable.

Hmmm...perhaps if its price comes down in a few weeks. Since ive seen unusual activity regarding separate 12V rails, a system with 6 Rails just seems like a marketing scheme. But then, as I've said, I know EXTREMELY little about PSU's. So if the Zalman, comes close in price to the corsair 850, I just may go on it. And hope like heck, that its not indeed the PSU making the curious shrieking sound that MULTIPLE people talk about. I do like its specifications! If I had the money, there would be no question.

An extra 10 bucks up front? If times are hard, why are you buying an 850W PSU when a 500 would do?
I have never found multi-rail PSUs to be an issue, you have to have a seriously unusual system for that to pose a problem (Say, a dual core CPU and 16 HDDs). Even then, that was because it was only a 16A rail. The limits on the Zalman are more generous on rails 2 & 3.

Corsair 850=144.99(before 25$ rebate)
Zalman 850= 169.99
Though the savings one gets from the Zalman is good. 214.99 originally

It's only the rebate. That PSU is only worth about $100, I don't remember seeing it go for that much more.

why would the 620HX be better than the 650TX? Ok, I see that the 620 puts out a few more 12V amps. Which raises another question. Why would they rate the 650TX, 650W? When the 620 has more amps and a lower rating? Now do you understand my intimidation LOL! I'll get it, its just gonna take some time :)

The 620HX is modular and multi-rail which adds significant expense. It is also designed with a more stringent noise criteria. Since the 620HX is multi-rail (and the maximum 12V output is always less than the sum of the rails, or there's no point, think about it) you're thinking there's more to the 620's output than there actually is.

Ok, I think I understand now. But I still raise a brow at modular design. Looking at the connection/extension for my CPU, it makes me wonder if im losing power there. If only a minor amount. I'm probably worrying for nothing LOL! Its a tested proven technology, or they wouldn't be mass marketing it. LOL, would they...(the benefits probably outweigh)

I've had several modular PSUs, and I've never had an issue with that part of any of them.

Well...I did it! I bought the 400W corsair, for my secondary PC. I didnt like it being inactive. Besides, it may go to my mother. Not sure yet. A lot of people think its quiet, and a lot of people think that ALL of their PSU's are good. Now I can experience them for myself, without having to spend TOO much :)
