Help me decide PSU for my new PC

[pous]

Hi guys. I'm going to be ordering this low-mid range PC for OC testing in the next couple hours, but I wanted to get some advice on PSU.

I'm stuck between this antec:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817103941&Tpk=antec%2bneoHE%2b550

and this OCZ:
http://www.newegg.com/product/product.aspx?item=N82E16817341012

Both are tier 2 I believe... I just wanted to get some opinions here

Also was trying to figure out Vista 64 Business vs Ultimate... and it's confusing so if you're stopping by anyway and have some info on that, that'd be awesome

Edit:
Suppose I should list what I want the PSU to power...

E2180 (Going to shoot for 3.0ghz, was told I could do it on stock cooling)
GA-P35-DS3L
Antec900
2x1GB DDR2 800 (G.Skill)
GeForce 7600GT (Running 1280x1024 resolution)
250GB Seagate SATA hdd

That's it really... I think I should be fine with either PSU.

actually in tier 2 along with the antec neo,

it has these 2 OCZ's:
OCZ GameXStream
OCZ EvoStream

but not the Stealthstream

I would say go with the antec.

Plus the antec has [3] 12v rails for a total of 54amps. Where as the ocz one has only [2] 12v rails totaling 36 amps. Handsdown I would say go with the antec!

Flip a coin... they are both good!

64 bit home premium!!! Not the others!

Thanks Frozen for advice towards Antec and why.

@ hughyhunter -- I would flip a coin, but FrozenGPU makes a good point Also, why you say home vs business or ultimate? what is the difference?

 

[hughyhunter]

Well I just say it as a satisfied customer with home premium... and also I've read that the Ultimate is overkill and kinda buggy.

I really like home premium though and think it will be usable for many years to come.

Can you set home premium to look "old school"? I do that with XP and love it.

^Yes you can make it look like the Win2K GUI.

@OP: I recommend you get a good cooler if aiming for 3Ghz. I got about 65-70C Prime95 with stock cooler at 2.95Ghz. I currently get 65C at 3.2Ghz with a OCZ Vanquisher. (I will be upgrading RAM and cooler soon).

Hmm.. I'll have to look into coolers some more I guess ^_^ oh well.

Thanks for all the advice

Here's another power supply for your consideration;

Looks like a good deal, but more $ than I wanted to spend on PSU given my power requirements, and also I don't think I'll ever order from Buy.com again after it took so long to ship the first time. (Held up the building of this rig, listed in sig) Maybe not a great reason to deny them my patronage but... Newegg is fast and good.
