Corsair VX450 + Dual GPU Card?

post #1 of 19
Thread Starter 
I am wondering if I would need a new PSU if I was to upgrade my system?

I am currently using a Corsair VX450 and I am looking to upgrade to a E8200 or E8400 and a 9800GX2. Would my power supply be sufficient? I'm guessing it is unlikely but I was wondering if anyone had any opinions.

It could be, not sure how much more power 9800GX2 use over GTX+ but I'm running fine.

9800GX2 is around 197w. The 450vx is able to do 370w on 12v so it should be fine for stock speed.

The minimum recommended is a 580w, I think you should look into moving up to the 650TX, 750TX, 850TX (Not sure if these are available yet), or the 620HX. Although the 450 might have enough power I think you'll only run into problems, especially if you plan on overclocking you CPU, ram, and GPU as this can increase the power draw substantially.
BAM!

Hmm, this post just came up.

http://www.overclock.net/graphics-ca...new-cards.html

It looks like the reference 8800GT uses 31W idle and 133W on load.

However the 9800GX2 uses 85W idle and 186W on load.

That seems like a big difference to me, maybe a new PSU will be in the works.

The manufacturer ratings are propaganda. Without them I doubt we'd have 1000W PSUs.

I'd say it's more to keep people from blowing up their computers when people buy a PSU that is rated a 25° c and can't handle what their running.

Get the 1000HX. It's reliable, has a long warranty (in general), and has 6 6+2 hookups, allowing any SLI/crossfire setup you can imagine. You could be running tri SLI, 8GB of RAM, and 2 quad-cores in a skulltrail and it would still be sufficient, even with a RAID or two. It will live out the rest of your current system (even with the upgrades), and you could probably use it in the next, without having to worry about power requirements. I myself use this in my current system, and it runs flawlessly. ^___^

It will only suck down the power it needs, so power consumption shouldn't be a worry. It's also 80+ certified (though most name brands are now), so it's relatively "green."

If it's too expensive, then go with a lower version; I still would reccomend a corsair for PSU (and RAM, for reliability).

FYI, it has a $50 MIR. Some good 850w PSUs cost more than that!
