Directron has some really great prices on decent re-certified OCZ PSU's. They aren't carried by newegg anymore, but they still have them up with their reviews which are great. 30 bucks for a 700 Watt psu, not bad! The only concern I have is that it is 4 rail, and I am concerned about my GPU overloading a rail possibly?

Randomizer indicates in the following article that it should not matter:

Just wanted to get some thoughts, hopefully from someone who understands PSU's enough to know if it will work fine or not?

The PSU is the OCZ GameXStream 700W ATX12V v2.2

The build:
ASrock Z77 extreme 4
I5-3570k
Asus GTX 570 dcII
2x4GB Gskill Ripjaw 1600
Samsung SSD

It's actually made by CWT, a reputable mfr that that makes units for Enermax and Corsair to name a couple. The base design for this PSU is used in the Enermax 82+ 550W: review here http://www.hardwaresecrets.com/article/Enermax-NAXN-82+-550-W-Power-Supply-Review/1426/11

If you're concerned about the Lepa PSUs, then go with the M12II-520. It's a great PSU. Advantages over Lepa B550/650:
1. Better voltage regulation and ripple; overall better power quality
2. 2 more years of warranty
3. Modular
To me it's worth the few extra dollars.

A power supply is definitely not the type of part I would play the re-cert game with. All of your other parts are relying on this thing and can be ruined by it as well.

If you're looking to save some cash, I wouldn't look to the PSU as the way to do it.

Maybe go for a 2500k processor and a Z68 board? This way you can spend more on a solid PSU such as:

The HX 650:

Also I am just trying to make room to justify upgrading the case I have picked to a 650D, which isn't worth a reduce on the mobo cpu imo. The savings at newegg aren't that great taking a step down, and on top of it I am getting a great deal through Micro Center that will cost 260 for the cpu and mobo together....can't beat that with a stick.
 
Review on the GameXstream 700W: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story3&reid=24 A decent PSU new but issues with ripple. Ripple causes damage to parts and will cause them to fail earlier than necessary. Do yourself a favor and get a good quality new PSU.

Unless you plan on SLI for that GTX 570, you would be good with a good quality 500-550W PSU.
A system with a single GTX 570 requires a 600W PSU with 40A on the 12V rails and two 75W 6-pin PCIe power connectors. The Seasonic S12II-520 is sufficient: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151094&Tpk=s12ii%20520
Lepa B550-Sa is a good PSU at a great price: http://www.newegg.com/Product/Product.aspx?Item=N82E16817194102
only$5 more than the GameXstream after MIR. Or the Lepa B650-SA for $44 after MIR: http://www.newegg.com/Product/Product.aspx?Item=N82E16817194103

I am inclined to believe you with your veteran status, but I have never heard of Lepa, how do you know they are good units? Also, modular would be great, but I think with the 650D I shouldn't have any trouble hiding the cables behind the motherboard tray?

Can't beat that for the price...also made by Seasonic, modular and high quality PSU.

+1 For the PC Power and Cooling. Great PSU for the money.

A couple of things. OCZ had some absolutely garbage power supplies and that link to the jonnyguru review of the GameXstream 700W is from 2006 before OCZ did a huge turnaround. You do not want an older OCZ power supply but their units after 2007 are pretty much all high quality.


I also agree with NOT trusting a remanufactured power supply. It's the most important part of your system and not the place to save a buck.

Yeah I read that review and it seems like a fine CPU, I like that it is SLI ready just in case, though my plan is to upgrade to a 670 this upcoming November which takes less power, and I think even then I would have to upgrade any of these PSU's for SLI I believe. I am tempted by the modular M12II-520, it reviews at better quality, though it does seem that more than usual reviewers are getting DOA units. I don't know if being concerned about getting the SLI function of the LEPA makes sense though, do you guys think it could power an IVY bridge and two 670's, or am I just going to have to upgrade if I end up down that path at some point anyway?

You plan on a 2 x GTX 670 setup? Then get a 750w power supply. If not at $50 the Seasonic made PC Power and Cooling Silencer MK III 600w modular PSU is an unbeatable value.

Well for now I'm at the edge of my budget and I am getting a single Asus 570 dcII. In November I am planing on upgrading to to a single 670, sli would be down the road. I was only just if its any reason to even consider the SLI of the LEPA now, or if I am going to have to upgrade either way (One of those PSU calculators told me 600 was what I needed for an overclocked Ivy and SLI 670's, but I would trust you guys over it). I am thinking the Shell Shocker Rugger suggested is the way to go.

Yeah I forgot they started doing that. Enermax power supplies have been around forever.

On the note of the TX650 there is one on Ebay, used one year for 60 bucks, still 4 years of warranty.

I already bought the 570, wanted to go 670, but had to make some trims somewhere. I got a great deal on the 570, and I can turn it around on ebay for I figure 80% of what I paid for it if I decide to go up to a 670 in November. I know its not a huge leap, but there is unlikely to be a next tier out by then, and the 570 is good....but the 670........

Those Benchs seem higher than what I've seen, I'm getting a 1080p, so maybe I won't need a 670 as soon as I thought. Though I haven't even seen tests of BF3 online so I am wonder what my FPS will be like there (I know you can't reproduce so no good for bench marks).
