Are these caps that bad that I should replace my psu asap or will they suffice for as long as the warranty lasts "5 years" ?

Anyone?

Now, that is a downgrade. All the reviews from 2010 had something generally regarded a little better.

But considering how much you're loading it (not all that much), the efficiency, fan, ripple, etc. it's most likely going to be fine.

I just checked out my old Coolermaster extreme power plus 650 psu, it uses the same samXon GF caps on the secondary as my XT 875w, I was using that psu for about 5 years with a ati 4870 and then an amd 6870 and none where bulging all looked fine, so I guess they can't all be too bad... tongue.gif

Not completely true. The primary side actually has higher frequency, generally, than the secondary, and greater ripple current, run closer to the rated voltage, etc. The main reason that the primary caps fail less and can be made lower quality at a lower risk is simply because of the larger size of the caps. Greater volume of aluminum, greater quantity of electrolyte, more thermal mass. It takes proportionately more damage to cause acute failure of a large 400V cap, than it does to fail a 16-25V cap. They're inherently more robust.
The electrolytic caps I've seen on the high voltage side all worked at low frequency, and the only high voltage cap that worked at the power oscillator's high frequency of roughly 50 KHz - 150 KHz was a polyester foil or film cap that coupled to the power transformer.

Ok so I have decided that I am going to get a new power supply within the next month or 2, my choices are limited to this site http://www.msy.com.au/Parts/PARTS.pdf

So I have narrowed it down to the Thermaltake DPS 750w or the Corsair AX760i, the AX760 has a good rep and the Thermaltake DPS looks like a solid unit also so what are you're thoughts?

you can save some $ by going with the Antec HCG 750 unless someone wiser has any objections.

Yes I saw that as well, I have never gone with Antec before and it looks like a decent psu so I am not sure, Money will not be an issue so I am looking for the best bang for buck psu that will last me a long time, so far the AX760i is at the top of my list because of its reputation but I am not well versed in psu's as some people here so I am open to all suggestions and arguments tongue.gif

That (High Current Gamter Modular 750W, which is a different design than the original HCG 750W) and most of the stuff in that price range is largely a sidegrade. You can do it, but I'd just use what you have until the warranty's out.

More so if you're not loading it 24/7 with at least 2-3 graphics cards. If you're hardly tickling it as it is, leave it be.
