Yes, it does. I have the same power supply and plan to get same videocard.
I think even can hold HD4870 or sli 4850 but the problem is that only have 1 PCi-E 6 pin conector.
Dont know why, if this powersupply have 33 amp 12v must have more conectors. ??
Should, depending on what else you've got in your box.
I've actually got this card (HD4850) running fine on just an Antec EarthWatts 380 PSU as I type. At the same time, I'm also not running anything else but one HD, one DVD-RW and my E8400 (not OC'd, although that can typically be done without adjusting stock voltages on this proc).
Lean and mean...the way it should be.

Hey all,
I'm new to this forum, so this is my first post
I had a question about the sapphire HD4850.
Does this card run on the Corsair CMPSU-450VX power supply?
Or do i need another power supply?
HD4850 draw maximum of 9 amp in the 12v rail at Stock (110W). Oced a maximum of 12 amps (6 amp PCI-e conector and 6 amps PCI-e 1.0 slot) (150W) ==> 22 amps left, 10 amps Q6600 with lunatic overclock, 2 amps for ram and HD??
10 safe amps left even with maximum OC you want. And they still requering 500w powersupply with 30 amps as a minimum?? im missing something??
I bought this PSU thinking was wayyyyyy more than enought, and now reading comments and articles im feeling i did a mistake?? wtf is going on??
You're underestimating on every component, especially oced q6600. Not to mention that no psu can work at 100% efficiency. 80% is for the best ones, under ideal conditions. Effect of aging further eats into headroom. And of course, it's always good to have room for possible upgrade or just for safety.

Dude relax, the VX450 is fine. Here's an upper estimate on what size PSU you need, brought to you by the handy eXtreme PSU Calculator v2.5:
System Type: Single Processor Motherboard: High End - Desktop CPU: Intel Core 2 Quad Q6600 G0 2400 MHz Kentsfield Overclocked: 3200 MHz, 1.3 V CPU Utilization (TDP): 85% TDP
RAM: 4 Sticks DDR SDRAM
Video Card: NVIDIA GeForce 8800 GTX
Video Type: Single Card
IDE HDD 7200 rpm: 1 HDD
DVD-RW/DVD+RW Drive: 2 Drives
Keyboard and mouse: Yes
System Load: 90 %
Capacitor Aging (+ W %): 20 %
Recommended Wattage: 431 Watts
Note that I used an 8800GTX 'cause the calculator doesn't have the 4850 yet. I also overclocked the CPU to 3.2GHz, threw in a couple of DVD burners, 4 sticks of RAM, and 20% extra for "capacitor aging."
You forgot the most important part of the equation with that nifty calculator.
How many amps is the psu rated for?
12v amperage
The 450VX has 33amps
For the 4850
"In my view the Radeon HD 4850 series require you to have a 450 Watt power supply unit at minimum if you use it in a high-end system, and I think that's barely on the safe side. Also recommended is 30 AMP's on the 12 volts rails for stable power distribution (on a single card configuration)."
One of my friends was able to SLI 8800GTS 640's and a AMD FX-60 (which takes a ton of power I might add), and it never exceeded 430-Watts. You should have no problem, unless you have 12 hard drives or are running a jet turbine in your case.
