8800GTX Power Requirements

I want to get an 8800GTX (eVga, no OC) but I need to know if my current power supply can handle it.

My specs are:
* PSU - Apevia 500W ATX-CW500WP4
* MoBo - Gigabyte GA-965P-S3
* DVD - Pioneer DVR-112D
* CPU - Intel Core 2 Duo E6300 1.86 GHz (Overclocked to 2.4 GHz @ 1.44 v)
* HDD - 160 GB Western Digital WD600JS
* Mem - 1 GB Wintec Ampo 3AMD2667-1G2-R (x2)

Thanks in advance!

So far this is all I can really find.  I am still trying to find the ACTUAL power requirements from a manufacture:

Ok, looking up your power supply:

It will NOT work with the GTX since it requires 2 PCI-E power connectors, BUT the 8800 GTS only needs one and your power supply may suffice for it's energy-sucking-from-hell's needs :)

"Nvidia suggest a power consumption of 140-170W depending on the manufacturer and the cooling device since it can also drain some power. Real tests made by the guys at Anandtech revealed that a high end PC that uses an 8800GTX series card consumes about 320W. And Im talking about a high priced Core 2 Duo with 2GBs of Ram here.

The conclusion is simple. 25-27A on the +12V lines for a single 8800 is more than enough. And in case you need a SLI configuration, make sure you have at least a 30-34A capable PSU. Note that not all PSUs run according to their specification and current on the +12V line may be lower in reality. In order to stay away from trouble, a good quality 430W-480W from a top manufacturer should be enough."

your power supply has 2 +12V Rails V1 at 16A and V2 at 18A  so you should have enough for it.

Challenge: The ESA office in Brussels wanted a reliable audio conference system for video conferences. Their requirement - No participant must be left out from the conference and the audio quality must not be compromised.

Granted, he does have (2) 12v rails, but only one 6 pin PCI-e connector and he would need one 12v connector from each rail to suffice.  You should be able to purchase a 4pin molex - 6 pin PCI-e adapter for the other rail if needed.  See, now I found a spec for Gigabyte's 8800 states that it only needs one PCI-e connector.  Also check out http://forums.nvidia.com/index.php?showtopic=42362 , this guy had the same exact powersupply as you.

Your video card needs 450W:

Thanks! Looks like I'll be needing to get a 650W PSU.
