Looking for some advice on the best PSU to buy.

Hey everyone; To start off, I'm running on an old system, but I don't have the means right now to just purchase a new one (That's been planned for down the road). As such I still want to bring mine a little closer to acceptable.

Right now I'm using an HP Pavilion: AMD Athlon[tm] 64 X2 Dual Core 4200+ with 1.00 GB RAM.

It comes stock with one LightScribe DVD Supermulti Drive/ CD-W and a DVD drive.

Because I plan on trashing this system or selling it for quite cheap down the road I only plan on putting in a ATI Radeon HD 5450 PCI-E. As is my system runs rather well off of a 300W PSU but I tried the 5450 and that wattage is no longer enough.

So I was just wondering if anyone could give me an idea what a reasonable wattage would be and suggest some models for me.

Thank you.
(If anymore information is required about the system just let me know and I will do what I can to update the post.)

  1. 300w should be enough, I suggest you just buy a quality 350w, what matters is the amps on the 12v rails.

    My suggestion:

    I chose a cheaped price one just because you plan to trash the system anyways, and Antec is one of the best in PSU's.
  2. I use zalmans 850 watt psu

    been really good to me so far with no problems. Almost no noise at all also.

    I know its probably over kill but from my experience upgrading a computer is just inevitable and with a good PSU you cant go wrong. Spend a few bucks if you can afford it and go with a solid PSU.
  3. Thank you for everyone who added in some advice; it was a big help as it gets me some models to compare and base my choice off of :)

    That is the type of PSU I'm going to run in a year or so when I build myself a brand new system for high performance gaming; I agree that it is better to get a solid high quality PSU but I don't plan on running this system for long enough to output that money right now.
