Hi newcomer and welcome to the Tom's hardware forum.

Well, that PSU don't have any certificate, and is better buy a PSU with at least a 80+ Plus certificate.

Take a look of this Antec 650W is a very good PSU, even, I think that is better that the 700W OCZ.

Now, that's the configuration of the rig? CPU, Mobo, RAM, GPU...because you only need a 650W or 700W PSU for SLI or Crossfire.

I do not recommend any of of the OCZ 700 watt models. All of the 700 watt models have shortcomings that were discovered during technical reviews of the products. The quality of OCZ power supplies is inconsistent. Some are are good. Some are adequate. Some are not so good.

Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. One example would be the Antec Earthwatts and Antec TruePower New models which are a major improvement over Antec’s older psu’s like the Basiq models.

It looks like both the PSU's suggested are quite a bit more than $45 after rebates and promo code.

However, they are right that you can find a superior power supply for a few bucks more. Here's my recommendation:

Don't skimp on your PSU! You can cut corners elsewhere, but get yourself a solid, clean power source for your rig.

Yes, I looked at the Antec but it is $85... if you consider the rebate the OCZ is only $45! Not a huge difference but every little bit helps with a new system build.

I have heard good things about OCZ but PSUs are so variable.... The only PSU that is ALWAYS recommended is Corsair but they are more $$$ certainly.

It is the age old dilemma... I don't want to put out the cash for the best PSU but I want the performance and stability of the best PSU :sarcastic: 

BTW, I want to place a 600w+ PSU for an eventual CrossFire upgrade.

^Good.

What Crossfire?. two 5770, two 5850, two 5970... If are a 5770, with a 550W is enough. For a 5850 and 5870 you need a 650W PSU and for a 5970 your need a 850W or better.

Upon further review...

I like this suggestion..... http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I don't know how I missed it as it is a solid name and a reasonable price... certainly the 40 bucks difference is not going to kill me.

Why I even wrestle with such issues is because I have a older CoolMax 500w PSU that is apparently crap according to some opinions but has worked flawlessly for me for 5+ years of constant use. (too bad it can't support PCIe) It always makes me wonder if some of the lesser PSUs may not offer the same level of quality.... assuming you don't mind doing the initial QC yourself.

Thanks for the input everyone!!!

Saint19... i'm going 5770.

yes in this case the antec is slightly better cause it has more total ampos on the 12volt rails, excpet for if you have a grpahics card that needs more than 22amps of power. correct me if im wrong, but i would recommend the corsair because it is less of a PITA to balacne h rails on the antec. however, yes the antec is a little more powerful.

was that confusing? sorry if it is!

Do you think the bronze certificate makes a difference? I know Antec is improved but they went through a phase of questionable product. Admittedly, I am drawn toward the Corsair name. It is ALWAYS in the top PSU lists.

Honestly, either likely work just fine.

I just wanted to add that I am using an OCZ StealthXTreme 400 watt in a work rig I built last week:

Pentium e5300 @ 3.5Ghz /Gigabyte G31 mATX s775 mobo (cant remember the exact model)
Radeon 4650

The PSU is very quiet, only cost £25, has cool looking braided cables and seems the business.

Also that was my first Gigabyte board, and Im definately going to stik with Gigabyte from now on - these boards are AWESOME!!! :D

I don't like the Stealthstreams. Read the PSU label. You have no idea what the maximum 12 volt current is.

+1 to jsc.

And I'm pretty sure that he don't build the same rig that you have.

This page shows a photo of the StealthXstream 400 label:

http://www.hardwaresecrets.com/article/794/6

The 12V rails combined maximum is shown as 372 watts = 31 A.

^That review is for a 400W PSU, and maybe you can get 31A, but I'm pretty sure that isn't always 31A.
