Just brought a 9800GT video card. Computer wont power up after install.(SOLVED)

Casually Hardcore

Hi,

I just recently brought this video card

http://www.newegg.com/Product/Product.aspx?Item=N82E16814143187

and computer refuses to power up after install. I press the 'on' button, nothing happens. Yes I do have the power supply on. I reinstall my old graphics card (EVGA 7900) and it works fine.

I'm suspecting power supply. My current power supply is an off brand and a few years old. My power supply is this.

Any suggesting?

Mr Blonde

Would a computer even post if it couldn't support the power draws of a higher end graphics card? I'm not sure, but that might be my best guess. Swap in your old graphics card and see if it boots.

Also, you plugged it in, right? Wasn't mentioned.

Wiley

My guess would be your off brand power supply can't provide the juice needed. Last time I bought a new graphics card I didn't pay attention to the power supply requirements and had issues getting it to work until I upgraded the supply.

Graphic card is plugged in.

Computer powers up with old graphic card.

Scosglen

when you say "doesn't power up", are you getting no fans spinning, no post beep or anything?

Casually Hardcore

No fans, no beep, no nothing

PeregrineFalcon

When you brought it, did you bring it all the way into the PCIe slot?

Try removing/remounting it. Sounds almost like it's shorting out if you get no fans/no beep/no nothing.

Also damn son, that's some ghettastical PSU you got there. Get something better.

Mr Blonde

What's the wattage of your power supply?

Casually Hardcore

Just tried uninstalling and reinstalling it, still nothing.

Maximum wattage on PSU is 450W

Wow. Those are some really wimpy 12V rails. I'm not surprised they can't run that card. You probably want something with at least 25A.
If you gotta go cheap PSU, get something like this

Which at least has a fairly beefy 12V rail and a ton of good reviews. Got one for my friend when his crapped out and it's worked just fine.

Wiley

Card requires at least 22a from 12v, unless I'm looking at it wrong your PSU only provides 17.

Casually Hardcore

Hmm....that would be obvious but I was always under the assumption that it ment combined amperage.

Well...I guess it's a good time to upgrade my PSU whether it not it's the problem.

Wiley

Yeah. The way it's worded it does look like it should be good enough. If you have the spare cash go buy a new PSU to check it out. If it doesn't fix it just return it and RMA the card.

Casually Hardcore

Went to Microcenter, grab a PSU, stuck it in an it worked!

Damn, dont you hate it when a $100 upgrade turns into a $200 upgrade?

For those who are curious, I did the right thing and grab a good PSU this time:

Hopefully this'll future proof me, seeing how I might as well grab a new MOBO, another HD, more RAM, and another processor.

Funny story that's the same PSU I have.
Funnier story it was recommended to me by someone else in the H/A section before.

I'm finding that it runs kinda loud.

My initial complaint is that it haves enough wiring to provide an electrical infrastructure for a small third world country. Other then that (and it isnt even a real complaint, just a 'damn'), it's a very solid unit at a very good price. My tower is a lot quieter then what it was before. Shoulda done this sooner.

It's like a H/A STPSU, except not sexually transmitted...
