A 500watt OCZ would make me a little nervous ...

Make sure to factor in at least 20% Capacitor Aging as well.

PSU Calculators are total junk and not reliable at all.

The card will replace a 8800GT Alpha Dog in the rig linked to my profile.

E5200 @ 3.25ghz
4gigs DDR2
1 dvd drive
A few fans
2 HDD(1 sata, 1 ide)

Fine to use it as a guide ... nothing more.

Since your psu is like 2 or 3 years old and only 500watts it proably doesn't have a single rail for the 12V. Depending on how you hook everything up ... you can overload one rail without overloading the entire psu. That in part is what makes the 312w recommendation unreliable.

Single rail on the 12V is the way to go ...

we talking about modxtream?

should be fine all stock running.

although id keep my nose on it, just in case.

i dont remember if they used the same oem for all of them, since some blew nicely.

I was under the impression it was an ocz psu, but it's actually Antec.

with that I'd grab the 2 molex to 1 pci-e and plug a molex to a seperate rail (harness as you mentioned) each to help balance out the load on the rails

Actually, I just checked Antec's website and I may just buy another connector. I think I have 2 empty outputs in the back of my psu.
Antec.com - Product: PCI-E MODULAR CABLE

thats an older unit, not sure on rail distribution could actually be just one fat one...let me see..

you wouldnt have a kill a watt or something to check juice at the wall do you?

i always check on a new build, and of course look for idle. if anything strange

pops up, aka bigger numbers than expected, i tear it down on the spot.

How old is the key. I would spend $75 to $100 and get a new power supply. No headaches after that. XFX ones go on sale fairly often.

I've run 2 GTX 260's off a 500 watt Antec (using 2 molex to pci-e adapters) without any issues... So I think you should be fine. Total system draw while folding on both cards was only around 360 watts IIRC.

yes, it could be a 5 year old model, maybe 3 years or so on the shelf+working.

earthwatts can pack a punch.

one 260 at full load should pull maybe 150-160 watts on the 12v.

of course furmark will add a percentage, good numbers to keep an eye on

if you want to play it safe
