Generic power supply units...are they really that bad?

Just so you can give a more informative answer, I'll post my the system specs below of the computer that I plan to buy:

If you look at the power supply unit, you'll notice that it's a 700W unnamed/generic PSU. Something interesting that I noticed is the 600W PSU is $5 more and the 500W PSU is the same price as the 700W...all of them are unnamed/generic. Why is this? After reading, I'm very hesitant to confirm this configuration because of how afraid I am of the PSU frying my computer. It would cost about $65 more to change the PSU to a Corsair 750W...this would be no problem if I weren't on a tight budget. With the monitor I plan on buying it has already went into the $1,050 - 1,100 price range...

Anyway, suggestions? advice? What should I do about the PSU? I'm very hesitant about the choice I made now... :??:

It's probably because they are cheap PSU's (just as you think). I wouldn't worry too much about it since your GPU is going to be low powered to begin with.

I gotta tell you... that case is gd fugly.

SV, by "low-powered," do you mean it's not a good GPU or do you mean that it doesn't use a lot of wattage?

Honestly, I could care less about the case. It looks decent. I'm more concerned about the internal components...

Not at all. You'l be able to max out almost every game on that GPU. It just simply doesn't use much power.

Okay, thanks. You had me So you think this PSU should get me by? I don't plan to overclock or play any "hardcore" graphical games like Crysis. Maybe something like Starcraft 2 when it comes out, for example. I just don't want the thing to fry my system..

You don't even need a 750W PSU for that system unless you plan on upgrading along the way, the power requirement for the 5770 is 450W for one and 600 W for two.

And your CPU isn't power hungry either. But you seam to be paying a lot for that build, but I could be wrong.

I'll be right back and see what I can come up with.

Generally speaking the generic / OEM power supplies are low budget, low quality psu's of questionable performance and value. They are not manufactured to the same specifications and standards as high quality power supplies. For the most part they are not capable of delivering the power stated on their data label. The maximum wattage and current (amps) on the +12 volt rail are usually lower than they should be. In addition the capacitors are of lower quality and are prone to early failure. That's why the warranties are short. The high quality power supplies usually come with extended 5 year warranty and in a few brand new models the warranty is now 7 years.

Okay, here we go

Better PSU, nicer mobo (crossfire), and it's total is only 763, leaving you some room to buy a keyboard and speakers, and a card reader (but you can get that down the line to).

Also maybe check out, and see what you can build off them

A core i5 build would be sick too.
