I have an old computer (4-5 years) that has a bad power supply. I need to replace it. The specs on the power supply are as follows:


TigerPro TP-300 12V
AC Input - 115 VAC 7A 50/60Hz 230 VAC 4A
300 W MAX Output

Any suggestions on what to buy?

I prefer newegg.com

what about this?

then antec reviews on newegg aren't as good as some of the others

Newegg reviews are completely worthless, with the exception that they help point out ergonomic issues. I figured out (when buying a PSU on reviews & specs alone, which is a bad bad idea) that most of those reviews are from right after the person installed the power supply. 5/5 eggs because it works! The egg reviews are not the be all end all, unless you notice that a bunch of people are saying their PSU failed shortly after they purchased it.

That being said, thermaltake isn't that bad a brand either. The warranty on that unit is particularly good for a $31 pricetag (after rebate), and given that you're just throwing it into an old beater computer you REALLY don't need anything more than that.

so you think that one will do fine then?


I don't think I am going to find anything lower than a 430 w

roll with the TT and thank yourself later.

6/22/2008 10:29:47 PM

Yeah, that TT unit should be fine. There is that antec one for $20 but it only has a 1 year warranty. I would say that antec stuff should all last for a really long time, but at the same time a lot of electronics products don't outlast their warranty period by very long... The thermaltake one really looks like the best deal for $31. Plus you could throw it into a new computer should you decide to upgrade the old one someday. 430watts isn't bad for a power supply (unless you're putting serious stuff in that computer).

While that TT unit is fairly good, I'd look at the specs first. The Efficiency is only rated at > = 65%. Look at better PSU's with a 80%+ rating. The higher efficiency, the less wasted energy and less heat generated.

Not only that, but a lot of lower grade PSU's rate their wattage levels at room temp to boost their wattage capabilities. Most of the time, PSU's will range 40-50 C and power levels drop significantly every 10 C. If you get a non-name shit box PSU that's rated for 400 watts, it could actually only give 230 clean watts at normal temps.

For your purposes, it really wouldn't matter since that TT fits your budget well. I have the same one on my older computer and has been working for 3 years flawlessly.

well the power supply is going into an old motherboard with a Pentium 4 2.8 GHz and a 60GB 7200RPM hard drive. There really isn't anything else to power besides the DVD ROM.

Don't cheap out on the one component in your computer that can fry all the others.

6/23/2008 11:59:13 AM

well thats exactly what I am worried about it. I dont need anything above a 430. Remember, I am replacing a 300w

6/23/2008 5:50:46 PM

^ It's not going to give your components more power than they need just because it's rated at 400+ watts. What you want to avoid is a cheap PS that doesn't send your components enough good, clean power. That's when the shit hits the fan.

I bought FSP Group FSP350-60PN-R1 350W from newegg over 4 years ago and it has given me zero issues.

That model isn't sold anymore, but there are quite a few to choose from on this page.

I am looking at a lot of the Antec units and they (maybe its just Newegg) don't have efficiency ratings listed.
