I want modular because of my case but dont know if its worth it.... will these power supplies also be able to crossfire later in the future?

good choice and hopefully your mom won't be to mad :(
A good 650W PSU will be plenty for a system with two 6870s. However such a system also needs four PCIe connectors, unfortunately most 650W PSU only come with two. You could use peripheral to PCIe adapters if you are happy to use them.

Assuming you are in the USA and buying from newegg

Good hardware before bling. Lose the cathodes and get a proper PSU. It is the one component in the rig with the potential to fry the rest, you don't want to get a crap one.

Also, your rig is unbalanced. In a $600 rig, a Core i5 will take up too much of the cash and force you to skimp everywhere else. Case in point, the generic brand 4GB of RAM, a novelty case, an old graphics card, no HDD (you need one) and this current problem of the PSU.

This is a much more balanced, budget rig.

Total: $555



 
The Antec BP550 Plus 550W you listed will run your system with a single 6870 but not two A single HD6870 requires a 500W psu with 32A on the 12V rails and (2) 6-pin 75W PCIe power connectors. Two HD6870s in CF require a 600W PSU with 44A on the 12V rails and (4) 6-pin 75W PCIe power connectors.Then you half to factor in other things like OC and breathing room.

+1 and if he wants to spend a bit more he can get a 7770 instead of a 7750

I did the micrcenter deal and I got like 80 bucks off of the motherboard and cpu. I dont care if i have 4gb of memory, just want enough to play skyrim. i dont need a hardrive already have like 6 hdds. From everything ive researched about the 6870, I wanna marry it. "all I want is Skyrim ultra and I will die happy". Matter a fact, f the crossfire (1) 6870 and a cup of cocoa and im good. I need a good cpu because i want to run ps2 emulators on my computer. the cold cathodes werent even included in the build total just to let you guys know. I was going to run off of the Hd 4000 until i can save enough lunch money to buy the 6870 which is perfectly enough...i dont need anything better then that from what ive gathered from price performance bench marks. ummm what else....? I didnt skimp much on anything I think...i wanted that case.... I also wanted that cpu...dont really know whats wrong with generic ram if i am not overclocking the ram... the whole point of the case is for the cathodes....i dont even know what im saying anymore, I am still not realizing how getting a $65 psu is skimping...
 


Well have fun trying to build a machine for $300 then. I can guarantee that it wont do what you want, and what it will do is going to be rife with problems.

You never state how high your willing to go, and the build you posted at the start was running at $548, I gave you a better system with quality parts for $7 more, hardly busting your budget. Also, if you have hardware already (Like 6 HDD's), F***** tell us! If you use the cash dedicated to the HDD in my build you can get your HD6870.

Also, we don't set the prices of hardware. You can blame Intel, AMD, Nvidia, manufacturers, international resource prices, differing tax's throughout countries,natural disasters and the whole capitalist economy for current hardware prices. We tell you whats good and whats not, and unfortunately bargain bin components are not good. To do what you wanted, you need to spend this much cash.

Quite simply, you came to us (The tech geeks, who know this stuff) for advice (multiple times, I'v read you'r other threads), and dismissed it each time. If you refuse to listen to us, do whatever you want. You can have fun playing Skyrim on your $300 machine.

That PSU will do, dont expect to crossfire on it.

I didn't state those things because this thread wasn't to criticize the build but the psu...not saying your build was bad, it's just that I already have the build waiting to be built at my house beside the psu, ram, and gfx which i wasn't going to get anyway until i get the 150(that's why it says without gfx card).It also said at the psu part that its 50-60.

T_T what do you mean not crossfire its a 700W!?!?!?
 
Follow the link you posted, says 600W. You probably meant this Supply.
http://www.amazon.com/OCZ-ModXStream-Modular-Performance-compatible/dp/B001IZ7MHU/ref=pd_cp_pc_0

750W is required to dual Crossfire comfortably (especially on older cards). 700W will work but don't expect much headroom to overclock and add more hardware.

Again, if you already had hardware, you should have posted that you had it. Otherwise we assume that you have nothing and we have infinite freedom to suggest changes to the rig, you have to give us info when you want advice. And it is pretty confusing to put prices next to parts you already have, gives the impression you don't have it yet.

If you wanted advice on just the PSU, why did you iclude the rest of your rig? All you had to say was
"3570k, HD6870 rig, want to dual crossfire later. have $60, what PSU should I get?". The answer would have been the same, you need to spend more, but you would have gotten it a lot quicker.

So is this a good enough psu....I don't want to be comfortable I probably wont even overclock for a long time and definitely not over 4.

700 is enough for me... the extreme watt calculator says at max 100% load to every component and overclocked to 4.2 it recommended 730 watt 691 min...my cold cathodes will be turned off most of the time and i wont even use the dvd burner... even at 80% it recommended 600watts... think im fine?

can you sign off on this psu or is it garbage....
 
Just quit messing around and get this you'll be able to run 6870 crossfire and overclocked with this i doubt hes going to answer back everybody has had enough of your temper tantrums

OCZ is a mid range brand, but its better than a generic. That PSU will perform to an acceptable standard, just don't bank on it lasting more than 2 or 3yrs as PSU's always degrade over time. It will be fine for your purposes.

That's weird, PSU calculators often under-estimate how much you need but that ones over-estimated more. 700W is sufficient.

I added random stuff that I might get in the future just to be safe. SSD, RPM HDD, 5 cathodes, overclocked to 4.2 with 1.5v even though i'm not going to go that high, extra fan, 100% max cpu and all components even though it wont go that high, 2 usb's, high-end mobo even tho its a regular board.
 
good choice and hopefully your mom won't be to mad :(
