Hi
I have been reading up on power requirements but am having a difficult time coming to a conclusion.
I want to purchase a PSU capable of running a Radeon 5870 Eyefinity. It is a power hungry monster.
I realise by current specs this pc is ancient.
Specs :
Core2duo E6700 (Possibly E8400 later)
2 x 2Gb ddr2 ram
1 x SSD
3 x SATA HDD ( one 7200rpm, two 5400rpm)
1 x PCI creative fatal1ty sound card
2 x Extra fans - 120mm
Aerocool E80 600W - my current PSU
According to http://www.coolermaster.com/power-supply-calculator/ I need about 442W (which I don't understand at all).
From my reading of the GFX card it peaks at about 350W usage, whilst my cpu peaks at 165W (which means about 43 amps/515W for the both at peak).
Then there is also the matter of capacitor degradation. From what I have read I need to add about 20% more capacity to take that into account. Doesn't help if I get minimum spec and the PSU fails in 6 months.
I am on a very tight budget and prices seem to go up at a rapid rate the higher wattage a PSU is.
There is also the matter of build quality, I did at one point consider a Raidmax RX 730SS, due to affordability, but have since discarded that idea.
I am contemplating going crossfire in future, so perhaps I should buy a PSU now that would make that possible.
Some advice from the experts would be appreciated.
Ps. At this point I am even considering buying an extra 350/450w PSU, and just extending the cables for my extra 8pin input on the GFX card. xD Messy to be sure, but cost effective it would seem.
