Buying new powersupply

I got the following system specs:
-Opteron 144(overclocking it to 2.5 GHz - I will NOT overclock anymore than this.)
-Epox 9npa+ Ultra
-2 harddrives(one is 80 gigs, the other is 120 gigs or something - I doubt I will buy more harddrives)
-eVGA 6800GS(overclocked to 500 for the core speed/1100 for the memory speed. I will NOT overclock more than this.) - I also might get a directX 10 videocard in about a year(but I don't want to buy another powersupply) It doesn't matter whether its SLI-supported or not because I will never buy SLI or even 2 ATI cards so that's out of the question.
-Corsair 1GB valueram PC3200 -Might upgrade to 2 gigs later but I got no plans for it right now.

Here's the story: I need a powersupply and I wish to keep the price below 85-90 bucks. Noise is not really a factor right now. My computer is pretty stable right now with a cheap 400W powersupply(little bit unstable but its not usually noticeable. I want to get a powersupply before this gets worse. It seems to be getting more and more unstable overtime). Thanks guys.

edit: someone showed me this. He has this and told me that its stable for him.: http://www.newegg.com/Product/Product.asp?Item=N82E16817709004 .I also looked at tons of other powersupplys. Can't seem to find too many reviews for powersupplies.
 
Looks like we need a quick recap on PSUs here :p

Just because a PSU works well for someone, if it is for 6 months or 6 years, that doesn't mean it will be stable for some one else (regardless of specs). So, when your shopping for a PSU, its really not a good idea to read a lot of product reviews (ones you find on online retailers), or, take advise from a unexperienced friend. Second, PSUs really arn't the type of hardware that is between stable and unstable, it either works or it doesn't (for a certain period of time).

Anyway, an Enermax Liberty 500W will last twice the life of that system (probably more), I haven't checked the prices on it recently, but if you want cheaper, you can't go wrong with the 450W Fortron.
 
Enermax Liberty 500w is $99.99 and is a good choice.
The Antec TruePower 550w is $89.99 and is another good choice.

Isn't there something good in like the 70's-80's range? Enermax Liberty costs 110 bucks with shipping - I really don't want to spend 110 on a PSU.

Its worth it. Just because a really good psu won't make your games run at higher settings or give you more FPS, at least you can COUNT on them to run at all, you don't get that with a crappy, cheap PSU. I wouldn't go any cheaper then a Fortron 450W, which is like $80 on newegg I think.

Btw, the fortron 450W is $51 bucks on newegg not 80. http://www.newegg.com/Product/Product.asp?Item=N82E16817104954
 
You're looking to spend <$200 in a years time on a GPU but don't want to spend <$110 on a PSU? To shame! Don't go cheap on a PSU bro, it's like the "You can never be too rich or too thin" saying. You can never have too much power. Go big early! I live by that statement. Spend $150 and get an XG-MGI Duro 750W (@ 50C) PSU or get the Enermax Liberty 620W. You won't be sorry later.

Why spend $80 now and spend $100+ later to correct a bad choice? Don't go half measures with a PSU.

I'd rather be here or another board helping people out on hardware/software then checking prices on hardware my whole day, it was a rough guess, no need to correct me.

You started good, but lost me at the end. It will be a long time before you need 750W of constant power (for your typical home user anyway, as manufacturers are also starting to slim down on power resources. 7800 to 7900 GPU line from nVidia is a perfect example).

Also, won't companies start selling small power-supplies for videocards-only? I am sure they will be cheaper than buying whole 750W PSUs. I read somewhere about that where you can place them in a PCI slot or something. I don't remember where I read that though.
 
You spend $80 for a decent PSU now and later spend $50-$60 on an SLI PSU because your $80 PSU won't handle the current GPU (in SLI or single) rather than spend $150 or so on a PSU that'll handle a future build? Why? I just fail to follow that line of reasoning.. Why spend 80% now and spend 50% later when you can spend 100% now and be assured that you are (reasonably) future proof?
 
Well, maybe I don't think so though. Considering there are good 700 watt power supplies from fortron and ocz (although a fortron rebadge) only going for 160 or less with mir's so its hard to say seperate power supplies for video cards would be worth it, these power supplies seem to be pretty good by the way.
 
Alright, right now I am basically deciding between ENERMAX Liberty 500W and Antec TruePower 550W. Anyways, I found a deal on pricegrabber for the antec that is 20 bucks less than the Enermax(both have low or free-shipping so shipping has nothing to do with the price imo). The only three advantages that I can see between the Enermax are:

1) Enermax has an effiency of 80% while the antec has an effiency of 70%.
2) Enermax has 22A on the two 12V lines while the antec has 19A on the two 12V lines.
3) Enermax is active PFC. Again, as I said before, noise is NOT a problem. I will most likely shut down my computer at nights so noise will not get in my way. That means this really is not an advantage for me.

Now my question is: Is the enermax worth the extra 20 bucks for those two differences?

^^^ For reference.

$85 buck Antec with shipping included: http://www.securemart.com/cgi-bin/future/ANB97693.html?pcode=1

$105 buck Enermax with shipping included: http://www.clubit.com/product_detail.cfm?itemno=CA6277816

Thanks again guys. I am really deciding between these 2 PSUs. I will probably buy either one no matter what.

Edit: If the difference is not HUGE and if I do go with antec, I may spend the $25 bucks left on a VGA cooler. ( http://www.clubit.com/product_detail.cfm?itemno=CA1924225 fyi)

Its already in existance, just buy a small PSU and stick it in your case, if you can find room. Most cases arn't made for 2x ATX PSUs, so it usually isn't easy to get 2 supplies in your case. I don't see how you would put a PSU in a PCI slot. One, it would run off of the main boards 12V line, which is coming from the first PSU, defeating the purpose of 2 PSUs. Second, have you felt your average PSU? Even aspire PSUs would break in a PCI slot.

You have narrowed it down to a couple really good choices. But, Antec is still just an OK brand, while Enermax is overall just better, it is worth the extra money for the Enermax.
