480W Tagan PSU
I'm currently looking at a:
Intel i3 540 (maybe a i5 if psu can handle it)
4GB DDR3 1600 RAM
480W Tagan PSU
I know it isn't the best of specs but I'm not made of money and I want something cheap before the VAT goes back up next year.
So would the newer rig be ok on that PSU? That's my main concern atm. I'm like to push to a i5 760 but I'm not too sure about cooling and power consumption. I did read on another forum that someguy with a AMD x2 3700, 4850 and 4GB of ram worked well on his 460W psu. But would the tagan be powerful enough for the new rig?
Also, any other suggestions about specs and where to buy them?
That PSU has two 20A 12V rails - each capable of 240W. It should be fine with an I3 and GTS 250. Or so the spec says - these are not always truthful. The GTS250 pulls a maximum of 150W and the I3 75W. PSU loose their power capability over time so you need some margin. That power supply is 6yrs old? Still may be fine - just make sure your PCi-E aux power connector for the graphics card and the MB/CPU power connectors are on different rails.
But I would go for a 550 watt, e.g. you can get a 550W OCZ fatality with 2 25A 12V rails for $64 ($45 with rebate): Newegg.com - OCZ Fatal1ty OCZ550FTY 550W ATX12V v2.2 / EPS12V SLI Ready 80 PLUS Certified Modular Active PFC Power Supply
