hey ppl i am in a serious buget i am building this comp currently
cpu:-e4300 c2d @1.8 ghz
gpu:-pci-e X16 gtx 460
mobo:-asus ddr 3 mobo
hdd:- 1 sata hdd
any good suggetions? remember a my comp needs at least 522 watts to function at peak load so i wll need a 600 watt psu for continous supply of 550 watts
Don`t bother with PSU calculators. They go very very much on the extreme safe side because lots of people go buy the crappy cheap brands that are not capable of providing anywhere near the power they claim. They sell by "peak" power and will blow up if you go anywhere near that at more than their 20C test temperature for more than a nano second, where as proper brands can do it continuous all day at realistic inside a PC case temperatures like 40C. In fact looking at a review just now, they were able to pull 1000W at 40C (limited by their load tester) from an 800W corsair PSU without any major problems, although the efficiency droped below the 80% needed for it's 80+ certification.
I seem to recall on a benchmark somewhere there was an i7 965 + 6GiB DDR3 + GTX460 + normal stuff like fans, drives, etc, pulling less than 300W at the wall under full load during benchmarking.
al right ppl i am now worried about 2 things the most
1. will it fit into my current cabinet :-
the dimensions are
Desktop, 7.2" (183mm) W x 17.5" (445mm) L x 14.5" (370mm) H
my current psu is;-Industry Standard 250 Watt (i.e stock)
so tell me if it will fit first
and my second concern is waht will happen when theres a power spike?
Find the similar picture for the 460 YOU will be buying if you like, or trust that this is the worst case. In any case (no pun intended), its up to you to figure out whether it will fit in your case. Take a look inside.
2) Power spike: Can fry lots of electrical devices . . . or it can be permanent. Can't answer without knowing how bad the spike is - that's like asking will my house flood if it rains.
There are outlet strips that protect against surges (ie, surge suppressors) and many will insure connected electronic devices connected to them.
