I had my computer built at a store and I had no idea of whether it was good or not,
I was on a budget and had no idea how to setup a computer of my own.
The thing is, so far, I have had no problems with it so far. It has been great for a good (about) half a year.
However, I was wondering if I tried to upgrade from an Asus 1024MB GeForce 9500 GT,
to a Radeon HD 6850, would that just be asking for trouble?
I hear it is not the best psu in the world, but if it could keep from exploding and support the upgrade I'd be happy.
If not then I guess I can stick with it until I can afford another Psu.

If it could work, then I have one last question about the installation.
Would the card come with instructions/manual? I'm not sure when I read about pins from the power supply I'm supposed to plug in?
Would I just be taking out the 9500 gt and sticking in the new one into the slot?
I can read but I think some visuals would reassure me more of what I'm doing.

I'm sorry if I'm asking such simple questions.
But I hope you can forgive me for my lack of computer knowledge and help me.
I'd be grateful for any feedback.

Your 750watt PSU has the specs of a 500watt. All I can say is that having quality PSU is the most important part in the computer since when something happens the crappy ones tend to take other components with them when they die!

suicide,homicide,genocide take your pick that psu is so bad i wouldn even flush it down a toilet

lil red switch on the back,lack of pfc
surely not 80+ certified
pathetic 12v output which is no more then 30 amps i asume

for reference 30 amps on the 12v rail = 360 watts when using the formula amps x volts = watts

but im almost certian that is a leadman 250 watt psu wich is a very expensive door stop

Well, after giving the stickied posts a good read,
this psu is very misleading. A little while ago, I opened up the computer thinking,
"Cool, 750w? Must be good."

Thanks to the forums, and your replies, I know better.
Now I know a bit better about the importance of amps, and the 80+ certified, etc.

So I'm guessing these would be better?
