What's the biggest VC my Antec TruePower Trio 550w can take?

Hi guys. Here are my specs:

Mobo ASRock G41m-S Socket LGA775
CPU Intel Core 2 Duo E7500 @ 2.93 GHz 3MB L2 Cache
VC 8800GTS 640mb (dead) waiting for a 5750 1gb
RAM Corsair XMS2 4GB 800Mhz
HDD Western Digital Caviar Blue 500GB SATAII
PSU Antec TruePower Trio 550w SLI Ready

Here are the detailed PSU specs:

I got this for $60 here in Costa Rica (really really cheap, Corsair VX550 is $140 here)

The biggest card this PSU has taken is my dead 8800GTS. worked nice as hell.

Here are the list of the cables:

* 20" cable for main 20+4-pin ATX connector
* 17" cable for 4x12V EPS12V
* 20" cable for 2x12V AUX12V
* 2 x 19" cable for 6-pin PCIe connector
* 1 x 35" cable with three 4-pin IDE drive connectors and one floppy connector
* 1 x 30" cable with three 4-pin IDE drive connectors
* 1 x 17" 4-pin IDE to two 12V only 4-pin IDE connectors (meant for fans)
* 1 x 25" cable for internal fan RPM sensing
* 2 x 24" cables with two SATA drive connectors
I'm gonna buy a 5750. I think this card consumes = or less than my 88GTS. My question is: What's the biggest card this PSU can take? it has to 6-pin connectors. A friend of mine said I should be able to use a 465...

Your friend was right. GTX 465/470 or HD 5850/5870 should be fine.

Dude, I know power requeriments for the card but i'm a noob in electricity... Electricity is just no that simple, sometimes you can run a VC with a psu below the systems requeriments and it works fine and stable, sometimes they require more... I wouldn't dare to run a 470 in a generic 550w psu. That's what I meant by asking that... Sometimes you can't trust the minimum requeriments or the PSUs... Some VCs say like 36 amps in X rail. etc...

Don't be such an ass for a question like that...

You're not running some generic low cost PSU. While it's not a top tier PSU it's perfectly adequate for most PCs.
It has a combined 42amps of +12V power (504watts divided by 12volts = 42amps). And it meets the requirments for a GTX 470.
EVGA website requirements for a GTX 470 video card:
Minimum of a 550 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 38 Amps.)
Two available 6-pin PCI-E power dongles

wow...very nice, that was the kind of help I was looking for, i didn't know that the combined rate was the one that counter *everyone laughs*. Thanks buddy.
