Specs: Microsoft Windows XP Professional, 1.81 GHz / 1.5GB
I'm planning to upgrade GPU before I buy a new desktop. So I won't buy once I bought the other parts. My current desktop has a Powerlogic 450W PSU. And as I saw Radeon HD 6770 can run on 450W. Can I run it well?

I'm tired of a freaking piece of crap pc o.O

As Rider stated any half decent Graphics Card will be too much for the PSU, ditch it and buy a decent one...

Are you looking for a PCIexpress 16x Card the best you can do is an ATI Radeon HD 7750 without upgrading the PSU:

Please post the amperage of each voltage rail. Get the info from the label on the side of the power supply.

450W is meaningless, please post the Amperage on the Rails, it is normally written on a sticker attached to PSU......

The Powerlogic 450W is not a 450W PSU, it's a 230W PSU. It says so right on the label. Notice the 2 ratings - 450W peak & 230W real. "Real" is what's important. And it only has 12A on the +12v rail. There should be more than twice that much. A decent 450W PSU would have no problem with the HD 6770. That one would crash & burn. It should not be used on a modern system. Here's the specs from the label:

When you go buying a new PC, make sure you choose a decent PSU.

Well. Here's what's written on the sticker:

It has an ATX-450W written in it and the picture of the sticker is different with mine.

On the Voltage tab:
AC Input: 220V

DC:
Orange: +3.3V and 26A
Yellow: +12V and 16A
Blue: -12V and 0.8A

and there something written below:
Max: 400w and another Max: 450w

I'll try to post a picture soon.

Edit: Yeah after I buy a new desktop imma buy a Corsair 500W.
