You WILL be pushing it too far. In addition, HEC is one of the worse PSU brands you could get.

The 955 + eSATA bracket combo find was actually my find a month or so ago, great way to save more on the 955
GTS 250 is more or less equal to the HD 5750, though it's still okay for the price.
The Team memory is $2 less only, and comes with no $10 mail in rebate. The Corsair XMS3 1600 9-9-9 for $43, 33 AR after promo code is still cheaper.
What PSU would you recommend, or at least how many amps on the 12 volt rail would you recommend?

And where did you get $43 for that ram?

Any is this motherboard I have selected going to be alright after all? Or is there an equal to SLI board (new)

with promo EMCZNPY25 = 59.99
and $20 mir = 39.99
This is only 25 amps on 12 volts...is that enough?? You guys make it sound like I need double the old, which is 20.

Amps on 12V rail doesn't matter, it's the PSU quality that counts; find something from Antec, Coolermaster, Seasonic and/or XFX. Those are my preferred PSU brands.
Even a quality 400-500W from those brands (or others that may be suggested depending) should power a 125W processor & 125W video card fine. A good choice to start with would be the Antec NEO ECO 400W or 520W, or the Earthwatts 650W or 750W which can often be had for good prices.

Will it hurt anything to run this crappy PSU? I'd like to at least use it if possible as it cost about 35 bucks...I've encountered problems before that the system just fries because the PSU is unstable, however this is such a high watt PSU, that I don't think there will be a problem.

You may get a pushed and DOA PSU right away to be honest... with the CPU and video card alone already consuming around 200 or so watts (nearly maxing your 20A) and what I consider an unreliable brand/build quality may really screw you over.

It may be rated 585W and seem to be high wattage, but look at the actual specs: generic, has more 5V/3.3V than 12V (so older standard), only 20A on the 12V (if you calculate it that is only 240W! Modern, reliable power supplies usually have the 12V rail comprising most of the rating - i.e. rated 650W, 600W is 12V). In addition, the 585W may be a peak power output instead of continuous. I have a power supply from Logitech rated 480W, it turns out that the actual continuous output (as marked on the PSU) is 330W and the 12V rail only has around 16A for 192W; it was in my dad's build, and I replaced it immediately.

Will trying to use this PSU harm my system. That's all I care about now - because truly I better try the PSU so it wasn't a wasted $35, or better yet not a wasted ~$60 for a "better" PSU.

In addition, I am about 70 dollars short, so I may be dropping my motherboard to a micro, and only one PCI-E slot. In reality, I'm 16..by the time I need two GFX cards I will probably be needing money for college...however, my original plan was this would get me through college, and I could game THEN by adding in more Ram, and GFX card, (and PSU)....for probably about 120 bucks then. Any opinions on this? As to whether I go with a cheaper, smaller motherboard...or if the idea is golden, and I need to scrape up another 70 dollars somehow, or any more combos on the stuff I still need - Motherboard, 4 Gigs Ram, SATA DVD Burner, GFX Card

You might want to go with a (cheaper) full ATX for the 8+2 power phase (i.e. 870 chipset); running a 125W processor (x4 955) on a 4+1 power phase (especially: unhestainked, on an MSI board, or with a tower cooler so no air to mosfets) can be a bit on the dangerous side and AFAIK there are no mATX AMD boards with more than a 4+1.

the mobo should know when it goes undervolt and shut down/off
it probably wont even power up properly

it could cause problems if the psu starts sending power spikes thru the system
i wouldnt even attempt it

orion had awesome car audio products back in the day
but going from 12vdc to 30-60dc to 0-60vac~0hz-22khz is completely different from 110 to multiple regulated voltages

So you're staying stick with the motherboard I have? It's an 890...and has some nice heat sinks (look that way). Crap has hit the fan though. That motherboard is now $102, it was about $84 before today... (Saturday 3 A.M.) I think...SUPER, JUST what I needed. In addition, it has a 8 pin power connector, this PSU doesn't even have that! So here I am, now, needing about $150 more with the CPU on the way already...guess I screwed up, should have done a cheap athlon build. I may as well just use the CPU as a paper weight because this did not work out the way I intended it to. Open to all suggestions now...since the motherboard is now so pricey, and I need a new PSU that can handle a decent motherboard with 8 pin.
