Corsair TX650W 650W Atx 12V 52A 24PIN Atx Power Supply Active Pfc 120MM Fan - DirectCanada

Id go with a 650 if your not planning on crossfire later on, even a VX550 would do for that build I would think but if it where me id go with the 650w =)

Are you guys SURE he needs at least 650W?

[H] Enthusiast - ASUS EAH4890 Video Card Evaluation
Full system load power draw at the wall: 363W

AnandTech: ATI Radeon HD 4890 vs. NVIDIA GeForce GTX 275
Full system load (not sure whether it's at the wall or not): 287W

Sapphire Radeon HD 4890 1GB Review
Full system load: 319W

Looks like a good 500-550W would be just fine for a single 4890 (HX520, VX550 or similar)

Do note that the test system used in the HardOCP review were with a QX9770, a Core i7 920 was used in the HWC review, and i7 965 was used in the AnandTech review.

Thanks, I appreciate the objective, fact-laden post. I remember when I got the 8800GT people were telling me 485W PSU would be cutting it - But I had no problems.


So my plan is to give the 4890 a shot with my 485w, and if it works, great, if its unstable, then I'll sell it and upgrade.


Thanks to everyone for the replies!

Unfortunately cheap power supplies may risk your entire system. Being in Calgary I'd go with this...

BFG GS-550 550W Power Supply ATX V2.2 EPS12V Active PFC 20/24PIN 6PIN & 8PIN PCI-E 140MM Fan - DirectCanada

If you can spare more cake...

Corsair TX750W 750W ATX 12V 60A 24PIN ATX Power Supply Active PFC 140MM Fan - DirectCanada

I don't think your CPU will be a bottleneck, but without a PSU upgrade your 4890 probly will not have enough power and it may perform like a 4650...lol.

As for other system possibilities, what speed is your RAM?

I'm running a 4890 with a Q6600@3.2Ghz. Nary a problem. Running Crysis @ 1920x1200 4xaa. 20-40fps feels like 120 though. UT3, eats it alive! Enemy Territory, not a problem. Though some graphical anomalies which I chalk up to driver support or rather the lack thereof.

Had similar but worse problems when I ran two X1950 Pro's in CF.

People tend to overrrate how much power is needed to power systems. Though if you do find you're having performance issues, computer tends to lock up more and problems such as those you should proabably invest in a new PSU.

This will give you a rough idea of what you should have for a PSU according to what else is in your system. It doesn't have the 4890 to choose from yet in the video card drop down menu, but I think a 4870 is pretty close in terms of power consumption.
