Is this going to work my main concern is my psu. Does it have enought power? Ik its cheap brand and crappy just wana know if the wattage is okay with graphics card and mobo and 2x 4gb 1600hmz ram, etc. Will my psu work?
Price out the components, or equivalent at newegg first.
Diablotek looks like an absolutely terrible psu company. Jonnyguru rated a top unit as the pits.
Newegg sells the same psu for $28. No way that can be any good.
Look for Seasonic, Antec, XFX,Corsair, and PC P&C for quality units.
Post your budget, and what you need to do, and you will get plenty of builds form the members here.
I have no particular problem with the 2500K and other parts.
Is there any particular reason why you would want to build a $700 system with a $50 powersupply? I have had two PSU failures in the past (Thermaltake and then a more expensive Antec) and it really is a pain in the proverbial.
I'd personally look to purchase something branded that you can trust. You should also consider that if your PC is on much of the time, a branded PSU with a high efficiency rating may pay for itself in a couple of years compared to a cheaper inefficient PSU.
