any reason to replace an RM650?

I plan on moving to Skylake in September to downsize to mITX for my move to a shared flat in London. I purchased a Corsair RM650 a few years ago and have not had any problems with it. Looking at the reviews for it looks fine as well. However, it seems on this forum that it is not well loved. Any reason I should look at replacing it with something like a SS-660XP2?
I my building with have an OC i5-6600k, 280x 3gb, 1xSSD, 2x HDD and AIO cooler.
 
save the money and go straight with a 6700K. I see no reason to go from a overclocked i5 2500K to another i5 6600K..
 
I'm going for the i5 more for the platform change than just the CPU and because I want to go mITX. I don't really do anything that would take advantage of the extra threads and it could be a very long time before we have a CPU the own its own provides sufficient cause for upgrading and the 10nm Cannonlake delay isn't going to improve the situation unless it results in a mainstream hex core. Also, an i7 will produce more heat in a SFF build.
 
Heat at stock clocks is non-issue in those chips, specially taking into consideration the higher clock of the 6700K so you avoid the OC part and have an already 4.2ghz chip that you can cool flawlessly with low profile coolers like the silverstone NT-06-E or NT-06 PRO, in the other hand games are starting to use more and more threads at the point we have couple of games in the market where an i7 4c/8t make a huge difference between a i5 4c/4t..

If you will be concerned about the heat, the main point of focus should be that 280X which can put some serious amount of heat inside the case, ive used a Gigabyte 280X in my Corsair C70 which its a big medium tower with huge amount of airflow and still CPU temps increased by 3 degrees under typical gaming versus my old GTX 780, nowadays intel CPUs are easy to cool so don't worry too much about that, specially using an AIO unit that will send the heat out of the case faster than any other air cooler.. the 6700K will prove to be a better buy overtime, specially if you are planning to upgrade to a high-end GPU later.
 
Since the thread's question is : "any reason to replace an RM650?" , i would say that i can find one reason, longevity.
Corsair RM series are pretty good PSUs when we are talking about performance, but they suffer at the build quality sector, since they use a lot of second-tier capacitors.
So the question is when these second-tier capacitors will start to fail.
Personally, if i had this PSU close to 4-5 years, i would probably have it replaced.
 
thanks, Sith'ari that is more helpful. I've had it for 2 years now. Would something like a Seasonic SS-660XP2 be much better? How long would you keep a "better" PSU?

You mean the 660 Platinum? http://www.hardocp.com/article/2013...num660_660w_power_supply_review/#.Vap9KPmWzct
It's an excellent PSU (i also used it for about a year) but a little expensive one.

I think that right now the best choice if you want a high-quality PSU , is the EVGA Supernova G2 650/750/850 watt.

Its build quality is great (*Superflower Leadex-based platform) and at a very acceptable cost as well. The 650 watt is under 100$

P.S. As for your question "how long i would keep a PSU" , personally, regardless of build quality, no more than 5-6 years max, because i never take unnecessary risks.;)

Unfortunately I can not buy from US retailers as I'm in the UK. I will buy most of the parts when I'm in China so the Seasonic and EVGA are actually the same price. I can pick up the Seasonic in China for £80 or the EVGA in the UK for £75. From what you say though you would keep the rm650 or one of the other two for a similar length of time. I will look into what I can recoup from my current CPU. Thanks again for the advice.

I was mostly confused about why my PSU seemed to have such a bad rep on here and if I should replace it.

Just like i said, it has pretty good performance but dubious build quality, which can not guarantee you longevity. (*when you reach 4-5 years of use i would advise you to get a better one;) )
 
If you're going for a mITX build, why not go SFX with a SFX PSU?
 
I wouldn't mind going with an SFX psu if I had a reason to. From what I can tell the Thermaltake Core V1 is the smallest case that can accommodate a 280x, 2x HDD and 2x SSD. Moving down to an SFX would not increase my case options. I would assume that it would give me a louder and lesss efficient PSU for the same amount of money and a lower capacity. Can any SFX psu compare to something like a SS-660XP2 and would any case fit my other needs and require an SFX psu?
