300W for a system with HD4870. LOL !! You crazy ?? ROFLAMO !
Go with Cooler Master 600W supply. For your system, You will need it.
Yours is a high end system.

Compromising on the PSU is the biggest mistake you can make. And screw your system.

And Single HD4780 is not good enough for playing new games at FULL HD with Full High Settings, Like Crysis. You will need GTX280 or HD4870x2 !! Make no mistake. Full HD means 1920x1080.


All the best.

its a good config but i would suggest you get a better chassis too...
at least Coolermaster Elite330 @ 1.9K

wait..
your budget is 85k..your posted config comes around 60k!
there is no reason you should settle on Primesource products!!!
with 20-25 K you can get an excellent PSU and Cabinet!

Crazy. It would blow up the day you bring your PC home!!! :razz:

Either get Cooler Master RS-550 Real Power 550W (5K) or Corsair VX450W (3.5K).

Warning: Do not go for Cooler Master Extreme Power Series!!! They are ticking Time-Bombs!!!

Its a good card, v.good in fact. am not saying its not nice.. its great VFM.
Even HD4870X2 will get killed by Crysis at HD resolutions and Very High Settings.

Here you go, one more
*www.tomshardware.com/reviews/nvidia-gtx-280,1953-18.html

So its like Its ok with HD4870, AVG FPS will be less then 30. For games like Crysis, if you play HD and full high settings with Anti Alising Turned on.

Ok, so here is sum serious stuff. :)

First of all, to the Original Poster, dude, with tat huge config in mind and in reality, PLZ go for atleast 750W of PSU...
Check it here if u wat to... ---> *extreme.outervision.com/psucalculatorlite.jsp

See my siggy, and see the PSU tat i hv got (coz i will be adding 2 more gtx280, in total 3 x gtx280's in three way SLi)...

U better go for ATLEAST Corsair TX750, or if u hv upgradation in mind, like suppose u wanan add one more 4870 (to make it Crossfire)..go with atleast 1000 or 1100W psu from Tagan.....

Both Corsair and Tagan are best of brands.. :)
-----------

Corsair 750W PSU (model TX750) ---------------> Rs. 7K
Tagan 1100W PSU (model: BZ1100) -------------> Rs. 14.1K
--------------


Cheers n e-peace...

Using tat paltry low brand PSU of 300-350W will jus NOT run ur CPU AT ALL... buddy... :)
-----------

So, here is the clarification:

1.) Jus one 4870 (and NOT planning to upgrade even in future) -------> 750W PSU (corsair)
2.) Planning to add more than one 4870 and also for futureproofing ---> 1100W PSU (tagan)

Just as an FYI, 1333mhz rams are pretty disappointing against d9 micron/elpida/powerchip IC based cl4 1.8~1.9v rams if you compare the price. Check the TDP for i7 processors as well. If you are planning to buy this seriously, make sure you get some charcoal and some chilled beer for some barbeque as well. No pun intended but one has to be realistic. If you are planning to use 1TB as a primary HD for the OS as well, you are better off keeping a smaller capacity hard drive for the OS alone. As for the psu- as said before- cant afford a decent psu, dont even bother getting a decent system. More advance the system, more sensitive it is to voltage ripples and spikes. What is the purpose for this rig? Gaming? I rather save money by going for e8400+ biostar i45+ 4GB cl4 g skills rams, corsair tx650+ cm 690+ asus dx+ altec lansing mx5021+ WD 250GB primary drive and 640AACS secondary drive. Even an e7200 does well even on stock. If your reply is going to be based on the generic "future proof", then I suggest you wait for 2-3 months time. Atleast you will get better processors with lower TDP and rams will become cheaper.

/nd as per my say the specs can be future proof only on basis of your usage, you can never be future proof if intend to high resource consuming apps and games.

if buying high end stuff u need to consider cooling options, PSU and cabinet
