What do you guys think of this video card and how much power it needs?

I plan on using it while playing iracing with an hdmi cable and I have a 50" samsung. Do you guys think this is a good card?

The box also says it uses 420watts. So if the card uses 420 watts how much does the computer use and what size power supply do i need for the computer? Is 450watt power supply ok to power the computer and the card?
 
The link comes up as broken on my computer though that could just be the Not So Great Firewall playing havoc with my browsing experience:grumpy:. So sorry I cannot comment on the card

Here are ballpark power consumption requirements for various system components in an average computer

Average PCI Card 5W - 10W
DVD/CD 20W - 30W
Hard Drive 15W - 30W
Case/CPU Fans 3W (ea.)
Motherboard (w/o CPU or RAM) 50W - 150W
RAM 15W per stick of RAM
Processor 80W - 140W

By my calculations assuming that you have no extra PCI cards installed, you system is potentially pulling something like 180-300 watts without a graphics card installed - possibly toward the higher end if you are doing heavy processing. That card will likely push your power supply "over the edge" in a graphics intensive application. For good system life, you shouldn't push your power supply beyond 70% or so as a rule of thumb. So, you will probably need an upgrade to an 800W power supply

The power recommendations from the website are overall for the whole computer with that graphics card. From what I can tell from the broken link, it's a XFX HD 6750.
 
800W? You serious? No mate, a 600W PSU will do you fine. Fan's pull (at most, if they're ultra high performance fans) 3W, and I doubt you'd have those installed. Go for a 600W, you'll do fine, even a good 500 - 550 would be more than enough, and it'd be more efficient in the long run.

Also, what other specs do you have? You'd be had pressed to get decent iRacing texture quality/resolution if you use that card with rubbish CPU, RAM etc. Give us some more details and we'll get back to you.

EDIT: However, for the price you'd pay for the 6750 (either $110 or $130, judging by a quick search) I'd recommend this instead: http://www.bestbuy.com/site/Asus+-+...1218475482880&skuId=4340602&st=6770&cp=1&lp=3

It will perform better than the 6750 (the next model up, uses GDDR5 instead of DDR3 memory [again, faster]) and that cooler is much better to keep your card cool and your computer quiet.

Well from the looks of that the card recommends a 420w PSU and that he has a 450w PSU, then he should be fine to install it. Should just be fine since his PSU meets AMD's recommended requirements for a 450w one. Though yes it would be recommended to upgrade to a HD 6770 if possible. Won't take much more wattage if at all and is a decent graphics card.
 
In all honesty, a 450 is a bit close for comfort. If it were mine, I'd deferentially get a 500W just to give myself leeway in case I wanted to install other peripherals later, and not go "Oh crap, should have upgraded earlier when I had the money..."
 
Power supplies at Tigerdirect.com

650Watt: $39.99
750Watt: $69.99 - this one includes free shipping

since you have to pay shipping for the cheaper one, the price difference is probably less than $20 - get the bigger power supply.

The difference in efficiency is marginal and you'll have a power supply to transfer to the next computer when you decide that the CPU or something isn't up to whatever new task you want to load onto it.

Since I couldn't see the link - I had to go with the info in the first post which seemed to imply that the card itself consumes up to 420 watts - not the overall system load.

The card does not chew 420W. The entire system, chews 420W with the card installed. Even a GTX480 only chews up to 150W from the wall by itself, so there's no way a 6750 or (preferably) a 6770 can chew 420W. If it were, it would require 3 8-pin plugs, but these cards only require a single 6-pin, plus 75W from the PCI-E socket. A 500W PSU is more than enough for the entire system. The one I linked would do him well as Enermax are a very good brand for their high end 1500 and 1200W PSU's. If they put that same work and enthusiasm into their smaller ones, that will last him forever and a day.

EDIT: Or as Nick and Road have already said, if his PSU is a decent 450W, it'd be fine. However IMO that's a bit close for comfort.

Yeah, defernatly should have gone with the 6770. It's cheaper and performs better. Plus, that cooler is crap so it'll run hot and make A LOT of noise.

As for that computer that's not too bad actually. A bit too pricey but not bad.

And no, a 520W is fine.
 
Power supply ratings are very inaccurate and over rated in most cases. They are not tested by Underwriters Laboratories to meet advertised ratings. Most power supplies, especially the ones that come with cases, are rated based on one minute run time. The only company that actually will give you a tested printout is PC Power and Cooling. Realistically I'd recommend thermaltake, or enermax, 600-650 watts to be on the safe side. ALlowing for any other future upgrades you might make.
 
As mentioned earlier, a GOOD 450W power supply should do. If in doubt, go for 500-600W - it'll be way within safe range.

Edit: Just saw your latest post - 520 should be fine! I have a MUCH higher spec PC with overclocked components and a heavy duty case and I run off a 700W with no problems.
