hi guys
i wanted you guys to recommend me a psu. but here are few things that i wanted. i have an Asus p5b deluxe, i have noticed that the connector on this mobo is actually 8 pin one while i am using the normal 4 pin connector to power it up. Is that connector same as the one on the 2900xt (8 pin connector). and i will also be crossfiring 2 2900xt, which will require 2 6 pin connectors and two 8 pin connectors. so if the connector on the mobo is same then i will be requiring three 8 pin connectors on a psu. please recommend me one. Hope to hear from u soon.
 


Having built my Q6600 system in April, I need a spare psu and I though this was really great for the price. If price matters you just can not beat this price for 18amp x 4 12volt rails, active PFC and 80-83 % efficiency.

The unit bought is the identical specs to the OCZ gamestream, (but for less money)

I considered this one spec for spec (try it) with the one I bought above, but it is $149 ($50 off):

And I have run my Q660 with this unit since April. Absolutely no problem with this one, it's great, but expensive:

I just placed my order for the 600 watt OCZ stealthstream 20 minutes before I read your post. I researched the idea of a spare psu for a couple of days. This is what I came up. $79 after rebate. When I saw the identical GameXstream for $30 more, OCZ kinda grabbed me by the boys on the deal.

even though i appreciate your help but the thing is that none of these psu fulfills my requirements. just read my above post once again. i want a psu with 3 8 pin connectors and 2 6 pin connectors in a psu.
 
I read your post, and I though adapters would solve any problem yu have. I noticed the dual 2900xt''''''(my keyboard key is stuck, bought a Logitech G15 too!) more than anything.

Your talking about a PCI Express 2.0 ready SLI capable PSU, and thats going to require some massive wattage! If you want to use three 8 pin connectors one for your mobo and the other two for SLI or CrossFire, you will need the Enermax Galaxcy 1000 watt PSU PCI Express 2.0 x2 graphics cards. PCI Express 2.0 with just one card uses up to 300 watts per card. The Enermax 1000 watt PSU has three 8 pin & two 6 pin connectors. I have seen them for $319.99, that sounds like the one to get.
 
Yeah, if your are running CF 2900Xts do not skimp on the psu. I was thinking I found a bargain on a 600 watt 18amp x 4 psu and wanted to pass it along. I think that Enermax 1000 just came out and is listed as a new product on newegg, if it's the unit I am thinking of. Likely no reviews yet. My Enermax personal use experience consists of a maybe 6 year old 460 watt unit that has powered one of my AMD 64 3400's without fail to this day. I have run 4 or 5 different processors and the same number of video cards and it kicks their butts. Then I have a more recent 535 watt Enermax SLI ready 18a x 2 12v that ran my 4800 x2 sli'd 7800gts for about six months before it was gasping for mercy. That unit you mentioned looks good. I wanted to buy the 500 watt Enermax Liberty tonight, but the OCZ unit I listed was more powerful for less money. 2900xts should be awesome. I could use it, but you don't want to hear how. My two 7800gts on a 16 x 2 nb still give great detail, color and clarity.

Lordszone wants a PSU that has three 8 pin & two 6 pin connectors. Theres no PSU in the world that has 600 watts and has three 8 pin & two 6 pin connectors. Because two 8 pin (PCI Express 2.0) connectors for SLI or CrossFire aloan use 600 watts 300 per card. Three 8 pin & two 6 pin connectors = PCI Express 2.0 ready for the next gen. PCI Express 2.0 graphics cards running in SLI. You are confused, reread the OP.
 


There are not adapters for OP's needs? When I read OP's post I just assumed adapters were an option. You are confused. Read my third reply.

I read your post, and I though adapters would solve any problem you have.
 


A video card uses 300 watts to function? What is AMD's recommended wattage for a 2900xt. I really wonder if a 1000 power supply is recommended for two of their units. I might be wrong, I'm just speculating. I have checked a lot of wattage used on a lot of systems with this and my entire systems do not use that much power. Are you talking about your refigerator? I've got an old side by side running in the garage cooling my Dasani. That with the one in the kitchen and the three others I run at my two office may equal that video card requirement your are referring to. The OCZ 600 watter I purchased for $79 tonight and recommended to OP won't run a CF/SLI system you say? Maybe you should think about becoming born again.

It is unlikely that many of you reading this are going to build a gaming system that requires more power than the one we built. Although headroom is a good thing to keep in mind, even the GameXStream 600w showed no weaknesses. That said, we did overclock the Intel Core 2 Extreme QX6700 processor to 3.33GHz, used SLI GeForce 8800 GTX graphics cards and plugged in eight 320GB Seagate HDD’s. Therefore while we may not have fully tested the capabilities of all power supplies, we believe a few things have been achieved. At the end of the day we feel gamers cannot go wrong with any of the OCZ power supplies we have tested here today. Again without expensive test equipment we cannot get too technical. Rather, we can simply tell you whether or not a power supply was up to the task of powering our high-end test system.

For 20 skins yoiu can learn a lot about the watts and amps your system uses:

Here's the PSU I purchased earlier tonight in case you think you might want to walk on water:

How many adapters do you think they used doing this? My new OCZ 600 watt 18 x 4 12v amp unit ran two SLI'D systems at once for this guy. This guy has got to get the young women. Just talkin' about it would say 'look how powerful a man I am' to a lot of fine wimmen.

In an effort to apply a large and realistic load, we connected the StealthXstream simultaneously to two platforms. Even with all these parts, the AMD-based system draws only an estimated 265W at full load, and the Intel system draws 349W.

OCZ's StealthXstream 600W power unit withstood all the abuse we could throw at it while maintaining stable voltage levels within plus or minus 5 percent of nominal values and less than 2.5 percent fluctuation.

This is especially impressive given that our dual-platform test "system" has twice the number of power-hungry components of a typical gaming rig.

Sure here it is, pay attention to the #5 picture. Also look where it shows three PCI-E 1.0 G-cards in tripple SLI or one PCI-E 2.0 G-card at 300 watts + one PCI-E 1.0 G-card at 150 watts. The Galaxy 850 seems to be the only one capable of doing SLI PCI Express 2.0 using two cards.
