Yeah 650w psu is good. Basically, make sure you dont get any of the corsair cx or cxm series. Get any psu that is modular, semi or full, and that is from SeaSonic, XFX, Silverstone or if your budget is low, get an evga.

Corsair CX is decent (when on a budget with 3yr warranty), i would agreed with mohammad, if you see better get it (at Tier 1 PSU)

So now its up to you if you cant spend too much money I would get any this http://pcpartpicker.com/part/evga-power-supply-120pb0750kr but if you dont like mail in rebates, get this psu http://pcpartpicker.com/part/seasonic-power-supply-m12ii620bronze. Nice internet tachy

650w on your PSU is adequate, but as the pass 2 above me said, it can't hurt to upgrade to a higher level of tier power supply.
But, if you're on a budget, the CX650 is still a solid PSU.

TheMohammadmo :

Is there a particular reason why not to get Corsair CS psus? Just curious as others have said they are ok.

AgentTran · Feb 7, 2014

Jeff Lo :

They are solid PSU's but the problem is with cable managements.
Corsair CX PSU's are non-modular, so all the cables that come with the PSU will be with it, and permanently attached on it.

Modular powersupplys include all the cables and you can plug in which one you will use.
This making cable management 100x easier and better.

ALso, even with the corsair cx750m, it still has most of the important wires all permanently attached so like agenttran said its really hard to do nice cable managment. Whats your budget for the psu I can recommend you right now

AgentTran :

I Just buy this done http:// i own it myself and its been trouble free (with 3 yr warranty too). Again, the issue with this line up is that they are made with slight inferior components (this being labeled a Tier 2 PSU) and could present an issue in the future (3yrs after is out of warranty). As with anything do your homework and ensure your PSU is made with excellent components and has a great warranty

TheMohammadmo :

Thanks! My budget is between $60-80 for the PSU, I found this, but if there are any better ones, feel free to suggest!
(Doing some research I found that Antec HCG psu's are considered good? http://pcpartpicker.com/part/antec-power-supply-hcg750m)

TheMohammadmo · Feb 9, 2014

That is a really nice psu for that much money. Here is another really nice one http://pcpartpicker.com/part/cooler-master-power-supply-rs720spm2d3us If I am not wrong, seasonic makes cooler master psus and seasonic is pretty much the best.
