Hi,
I am almost at the stage of putting together my new gaming pc.. but I'm not sure which PSU to go for, and how power heavy I really need to go.. Money is tight, so any help would be great.
This is what I have going into my build...

Asus M5A97 EVO m.b.
AMD FX 8350 CPU
MSI R9 270X GPU
Win 8
8gb RAM
1 SSD and 1TB HDD
DVD RW drive...

Any suggestions would be great..
Cheers.

In the current setup, you shouldn't need more than 500W, hence I would recommend the Corsair CX 500 or CXM 500. Also, the EVGA 500B is a good option. If you want room for upgrades such as more gpus or overclocking, I would suggest a 600W or 650W. Again the Corsair 600W series or this time the Fractal integra R2 650W would be a wise option. Have a look for best prices but these are the 'cheapest' power supplies for you imo.

To check your exact system wattage you can use a PSU calculator such as http://extreme.outervision.com/psucalculatorlite.jsp
Hope this helps.

The corsair cx series uses cheap secondary caps with a short life. Get the 550w XFX it's not real expensive and it's a quality unit. If you want a modular the 650w evga is a good unit aswell.

Thanks mate.
I didn't think of or even know about these calculator thingy ma bobs... Have to say I'm a tad suprised at how low the requirement is though...
It is safer to assume that prehaps I should still aim to get a couple of hundred watts more than specified as to not put too much load on the psu, even if it is adequate...
Quick question, how doyou rate the FX6300, I was thinking of going with that, but got a little carried away when ordering some stuff and got the FX8350, can't help feeling I may have gone alittle over board...
Cheers again.

Yeah the fx 6300 is awesome value for money but the 8350 isn't bad either. Now that you have bought it, don't bother returning, keep it. Also don't get a way too big PSU such as over 750W because when you only use a small portion of it, the efficiency is not at its peak. Best efficiency is around 80-90% load on PSU.
