Will my 500w PSU push an overclocked I5

you should not have a issue with that setup and overclocking the cpu. Real question is what is the reason you want to overclock that cpu, unless its for shock value there is no reason to overclock a 2500k.

That's a lousy excuse for a power supply, do yourself a favor and upgrade

@op if you cannot afford to upgrade you should be fine for some time but as delluser1 says you should get a better power supply, If you need to know good brands and so on ask delluser1 he is a expert at psu's

Yeah, that PSU was one I had on my last build but it didn't get a lot of use so I wanted to try to scavenge it even though I know better. What do you reccomend?

Well,to answer the question proper i have to know the specs of the videocard also,or you using onboard video?
If so,the PS should be fine,also you can check your PS behaviour with the help of some sensorsoftware like hw32 for example.
Try increasing the 2500k in steps and watch how the PS handles it with the software.
Or try software like http://www.passmark.com/products/bit.htm

You can always tell exactly what PSU requirements your PC has by plugging in your hardware into the PSU calculator at the link below.

I recommend Seasonic and PC Power and Cooling PSUs.

  Oops Got the sapphire on radar now.

well , 500Watt Is enough , but it will limit you somehow , you cant Get Higher Vga card & run it 100% Fine , & even your CPU , i think something between 500-600 , & if you can get 600 Watt it will be great .

I tell this From my own Experience , i ahd to pay Again for new PSu just for Littlw Upgrade . so Grab something that wont Limit you if you ever wish to upgrade to 6870 or something .

because i am sure you will feel the need some day . Good luck

yeah i was in the same boat as stev

had to buy a new power supply a little while ago

had a powerpc psu or something like that, it lastest 5 years then started giving of electrical noise from inside it

only branded one i could find local was a gigabyte one for £50 which is rubbish,

only 450watt sustained and 500watt peak, its going in the bin when i buy an i5 in a few months


it is really loud, my fault only exausast fan on pc, going to add fans to new pc build

what you buys think of the antec 300 for cooling,
what case do you guys recomend for cooling/quite for £50-100 preferably able to fix atx board or bigger

I was looking at ghetting this one, any thoughts?

You'll only need that much power if you're considering Crossfire, of some higher end cards, which would require more pcie connectors.
You can do better in that price/power range

700 watt is more than you need , but if you can get it Then go for it , who knows maybe someday you wanted to Crossfire or Put 6990 !!!!!

ANy way if you ask me ill say its better to have PSU more than you Need !

I have 685Watt & i am so Satisfy ! i am so happy that i didnt Buy 530 watt as Shop keeper TOld me because i have Calculating Software & it Recommends me to Buy My PSU which i already have . Thank God

Thanks Delluser!
