Hey guys, so i posted recently about that my current psu is REALLY bad, and i needed to change it ASAP. So, im about to buy a new psu but i got a MAX budget around 100$, Prices are alot diffrent in my contry (Denmark) so its expensive but will the Corsair RM650, 650W PSU do the job
or not?

I dont wont to change it again like in 2 years but will it last long enough with this system?

Specs
MSI X99 SLI+
I7 5820K
EVGA Geforce GTX 980
16Gbddr4


EDIT: Or would this do the job too? Corsair CX 750W PSU ?
 
Solution
No, stay away from the CX, CS and other Corsair budget units. For that GPU you need to use a Tier 1 or Tier 2 unit of 550w or more, here:

Tier 3 units are problematic when used with gaming cards that require supplemental power or overclocked rigs. If you use a unit listed at Tier 3 or lower, you most likely WILL be replacing it in two years, if not sooner, since they pretty much all use cheap Taiwan caps.

Agreed, the RM units are ok. I still like any of the Tier 2 or 1 units by Seasonic, EVGA, XFX or Antec better though. I rarely see any threads regarding failures on those units but I do sometimes see them, much more frequently, on the Corsair RM and HX units. Still, if you can get an RM within your budget that has enough capacity, it's a good bet you'll be fine.
