I'm currently purchasing & planning to build a fairly budget gaming PC games such as Far Cry 2 & S.T.A.L.K.E.R Call of Pripyat being the newest games I play.
I'm buying a 2500k i5 that I plan to overclock slightely up to around 3.6/3.8 just for a slight boost to browsing and gaming.
EVGA 550ti GPU
either 8 or 16gb of RAM (corsair vengence low profile)
A large Nohctua NH d14 processor cooler
perhaps an ssd
blu ray drive and a standard dvd drive
ASUS P8z77 - V LX motherboard.
I know that most i5 prebuilt computers come with
a 400w, and a GTX550ti is a reccomended 400w although its tdp is around 160 I believe. but Is a 600w enough to run all that stably? and underload just in case I do pick up a more modern game (cyberpunk looks cool, and I know Ill need a more powerful graphics card to run it)
Ah thats no worry, I've a mountain of cable ties, a Full tower case and Ill try to use as many of the leads as I can.
you will be fine especially since you plan to use three HDD, you will end up using most of the cables anyways. Ive built plenty of PCs using both modular and non and find little difference between the two (at best on a minimal hardware PC i may save one to two cables)
most motherboards now use a 24 pin mobo connector and a 4 pin or 8 pin CPU power connector. they have used that set up for some time although older mobos used 20 pin power connectors.
some older hardware use molex power connectors while newer hardware uses SATA. most modern graphics card use a 6 pin or 8 pin power connector.
your corsair will be able to handle any of those set ups.
