I don't know the requirements of those nVidia cards but a 460w supply MAY be cutting things a bit close for reliability (my GTX 285, no longer made, has two power connections... but I have an 850w supply)
Use these to check
Power supply calculator http://extreme.outervision.com/index.jsp (the PRO version)
Well, HP offers video cards with similar power requirements (~160 watts) in their configurator, and the calculators say that mid 400s will be sufficient, but I suppose it is cutting it close. How much of a concern should this be?
I can only tell you that my PERSONAL preference when I built a year ago was go get a "large" (and well rated in reviews) power supply so the PS would not be running near maximum with my total hardware - http://forums.adobe.com/thread/652694?tstart=0
You will probably be just fine with your system... especially since HP would be the single point of contact if there were hardware problems, and since HP says the PS is OK for the machine
Side note - until they outgrew the computers, both wife and her sister had HP machines a few years ago and, while there were never any overt hardware problems, when either had a question about anything concerning their computers, HP provided very good support
I build my own (and built my wife's current computer) so pick exactly what I want based on budget -vs- needs... but IF I was buying a computer and was restricted in brand... HP would be one of my viable choices
That configuration would be more than enough for HDV and still editing. The question to ask your IT department is can they support you with the video editing applications. If so then you are in great shape. If not then following your IT's preference does not really help you.
Thanks for your responses.
No, IT can't really help much with video editing, BUT I do need them for things like Exchange connections, automatic backups, antivirus, shared server access, printers and other things this machine will do besides editing. They'll also handle hardware failures and troubleshoot when things aren't working so I don't have to. In general, they'll be less likely to give up and blame the vendor if the vendor is one they approve of. And more likely to return my calls promptly.
"Exchange connections, automatic backups, antivirus, shared server access, printers and other things this machine " - All of this is User/OS specific and should not matter what system you have. Network specific components are controlled on the servers so that also is not system specific.
"They'll also handle hardware failures and troubleshoot when things aren't working so I don't have to. In general, they'll be less likely to give up and blame the vendor if the vendor is one they approve of. And more likely to return my calls promptly." - This part is a shame but understandable considering the state of support these days from both system configurators and software manufacturers. "Blame it on the other Guy" has become the standard response rather than actually spend the time to try and isolate the issue. Many configurators though will support through your IT department if you run into issues and Turnkey configurators should handle most of the support outside of the network specific components. So you might have more ability to select what you want than you might believe. Also deciding the primary task of a system really sets the priority for support. If the primary task is for editing then that should decide your support requirements, which can include an Adobe support plan to backup your IT department for that side with the HP systems btw. If other functions are the primary tasks then obviously stay within your IT departments preferences since most support will be with the components they admin.
Eric, I appreciate what you're saying. If my needs were more complex and/or video editing was my primary function, it would absolutely be worth it to buy the machine best suited for the job regardless of IT's preferences. But I also have some sympathy for our techs, who have heavy workloads and responsibilities to support hundreds of machines, prefering a short list of vendors. If I were in business for myself and supporting my own machine in an ecosystem I controlled I would go in a different direction.
To address the issue of the primary task, no editing is not the primary task, but it is the task that is most demanding of the system and so is a primary consideration for that reason. So I guess I'm looking for a reasonable compromise and I want to be sure that I'm not overlooking a shortcoming of a mass-produced system that I will be regreting in a year or two.
