Power supply notes :


* Connection to the system power supply is required:
o 450-Watt power supply or greater, 30 Amps on 12 volt rail recommended (assumes fully loaded system)
o PCI Express compliant power supply (recommended). Connect directly to the power supply with a 6 pin PCI Express power connector
* For CrossFireTM: 550 watt power supply or greater, 38 Amps on 12 volt rail


As stated earlier: Powercolor focus more on getting their cards out there at a reasonable price point rather than the bundle that is with the card. Having said that this VIVO card has everything you will need and more to connect this to an output device.

Cables include:

* 2 x DVI - VGA connecters
* Composite Video to Video cable
* S-Video to Dual S-video out and dual Composite out
* S-Video to Component out
* Dual Molex to PCI-E Power connecter
* S-Video to S-Video cable

This is very complete and I am impressed with this hardware bundle.

Software includes:

* Latest ATI Video card drivers
* Cyberlink DVD Solution. Includes PowerDirector, PowerDVD, PowerProducer, MediaShow, MusicMatch, Power2Go, PowerBackup (trial) and PowerDVDCopy (trial).

Although lacking in any games this is a decent package, especially for those wanting to take advantage of the AVIVO features of this card. Personally I have not used any of the "free" games with any of my cards as usually these are not AAA titles.

Also included is a Quick Installation Guide, Users Manual, Crossfire Power Supply Requirements advice and Warranty Information.

The package is thorough for the connectivity and although not amazing in the software stakes, it is acceptable.

The Cooler

Lets take a look at the cooler that is on the X1900XT

powercolor x1900xt

The card is still using the stock ATI cooler that we have seen on previous models such as the X1900XTX. This is a decent cooler but is very loud when put under extreme load. The cooler does have its redeeming features though. It has copper contact with the core and memory and is very efficient of taking heat away from the card. This makes sure the heat stays away from the inside of the case.

I have to say that despite the core getting fairly hot at times the fan does not spin up that much, only after gaming for about 1/2 hour. However if you are looking for a quiet life then you will either have to buy another cooler for the card or just choose something with a cooler that doesn't make the horrible "whizz" sound that this one does under full load.

Nice review. Good pix & benches too, Kempez Very thorough. You should use that card, hehe..your GTX get's smacked around by both cards lol, it's depressing (for you at least).Quote

Nah not depressed.

3 reasons:

1: nVidia's drivers are better

2: My GTX doesn't sound like its about to take off

3: I know I'll change my card when DX10 cards come out

Nice card thoQuote

LOL good point. The X1K is quite loud, but christ ever stick your hand back there? Pushes at least 60 CFM at 100% if not more.

Yeah but the nvidea cooling fan has a great throughput with none of the sound. the cooler on the GTX is far superior IMO Quote

sweet reveiw mate and agreed nvidia's cooling solution is very capable sound-performance wise .
