PSU suggestions needed.

Corsair 650W. Base price $105 - $10 MIR = 95 - 21 Bing cashback = $74.

If you're serious about running Crossfire/SLI, I wouldn't go lower than that.
Myself, I went with the PC Power and Cooling 750W. I think spending money for a quality PSU is definitely worth it.

PS At zipzoomfly the corsair 620W is actually MORE expensive than the 650W or the 750W model. Go figure.

Well the 620HX and the entire HX line is suppose to be Corsair's higher end and better quality PSU line. Combined with the fact that the PSU is module, it makes sense that the 620HX is priced higher than the TX line like the 650TX and 750TX.

Seems the track record would indicate the Enermax is more likely to die soon.

I would say that is not likely at all. Both PSUs are excellent quality and extremely reliable. The Enermax has tighter voltage regulation and slightly better efficiency though.

Well, that's because the HX620 is considerably better than either. The TX750 uses a CWT platform with good performance overall but quite a bit of noise, and the TX650 uses the same platform as the HX620 except with some cutbacks to reduce the cost, and as a result it is also much noisier (although not as much as the TX750). Not to mention the fact that the HX620 is modular.

I was looking for something in the lower price range that the Enermax fits into after rebate. Is it as good or worse than the Liberty? Seems like there are more complaints of failure with them in the long run than Corsair units.

The Antec is about equal in performance and quality compared to the Enermaxes; perhaps a bit better. However, it is also quite a bit cheaper than either of them and has more output capacity. It would be a better choice.

The Antec goes for $94.99 on Newegg while the Enermax is $69.99 after rebate on ZipZoomFly. It should be sufficient for parts which are power equivalent to an AMD 955 and two 4890 cards?
 
Which Enermax are you referring to? You mentioned two different models in your post above. And you didn't link to ZipZoomFly, so I had no way of knowing that the prices were lower there.

I bought the ENERMAX Liberty ELT620AWT-ECO 620W for $52.4 but it has not been used yet so I could sell it and buy the ENERMAX INFINITI EIN720AWT 720W for $66.1 after cash back and rebates.

Is the extra 100 watts worth the price difference and would that extra power be suitable for the setup I mentioned above? As of now I have an AMD 955 and Radeon 4870 1GB. I will Crossfire the 4870 later on but it would be nice if I could use the same PSU I use now for a later upgrade where I may have dual a card setup with the power needs equal to two 4890's. This wouldn't be until 2-3 years later so I could just buy a new PSU by then but the prices don't seem to drop by much with time so I may as well buy what I'll use later now.

I don't like the seemingly higher failure rates with the Infiniti 720 unit versus a Corsair or another similar unit. I also dislike the short native cables which are approximately a serviceable length of 15 inches. It's also a con that it only has one 6+2 PCI-E connector and two additional 6 pins.

The 620W PSU would be plenty, but for such a small additional cost, I'd go with the 720W PSU.

That's good to know. I keep hearing people say to not run the PSU at more then 80% capacity, which wouldn't a 620 be nearing that? What do you think of the failure rate of the Infiniti 720?

You wouldn't be nearing the limit even with the 620W PSU. There's nothing wrong with the Infinity 720W in terms of failure rates as far as I know.
 
Please post a link to where you heard these things about the Infinity. Tripping breakers only happens when the breaker is overloaded which should never happen with a 720W PSU, and problems with simulated sine wave UPSes occur as a result of Active PFC but are still not a major problem with most PSUs since the only time the PSU will be running on a simulated sine wave is when it's on battery, which will not often happen. In any case, you'd be better off with a true sine wave line interactive UPS instead.
 
I'll recommend BFG. Though I have perhaps an older model toughpower..it's been going strong for 13 months and has powered several hungry systems, most notably a 4870x2 and a c2qd overclocked...and current system now in sig. Never has given me issues.

Those were reviews from Newegg.

You said a 620w unit would be plenty. What if the CPU and GPUs were overclocked?

Right now I'd like to go with the Corsair as it has the combination I like the most with the longer warranty and better cables, but if the Infiniti's extra power would make a difference in an overclocked setup with a few HDDs than I may go with that.

It would be plenty for an overclocked 955 and 4870. For a pair of 4890s it would still be enough, but I'd recommend something with a bit more headroom (~750W).

Which Corsair are you referring to? And if you plan on going with an overclocked dual-GPU setup in the future then I recommend you spend the extra few bucks to get the Antec 750W PSU I linked to above.

Corsair 620HX.

I can't afford more then what that or the Enemax Infiniti 720w would cost me after discounts.
