Hi all, The rig in my sig, (sounds fun - hangs around with the cat in the hat!) needs a new power supply. I burnt out the 350w one with my 7900 and now i have a rather cheap and VERY loud 600w cheapy cheaper from ebuyer. I need a new one, and ideally it will be silent, but those days are long gone now, and in order to have enough to power my beast, i'll need 400w+ at a high efficiency or even 450w. I dont plan to have a second VGA card, my mobo is non-SLI so there's no chance of that without rebuilding the whole system, (was a design choice to stop me spending money!!!) but it isnt as obvious as it used to be to get a quiet PSU. We have an old Athlon XP 2600+ system in our lounge with a Geforce 5700 which is our MythTv box. This runs SILENTLY, and i mean silently. The hard drives are the loudest part of that system. The problem is times have changed, and the supply we have on that mchine just would't cut the mustard on my computer. For a start, it has no 4-pin P4 connector, no PCI-E, no SATA, and only 20 pins for the motherboard. So... i need a new power supply, the one i have does the job, but i would like to be able to go to bed in the same area code as my computer without the PSU fan sounding like a bloomin footie stadium on matchday. My selections so far... NorthQ 4774 400W 12-17DB 140MM fan w/SATA and PCI-E (does anyone have one of these? are they really 12-17db?) Zalman 460B (i hear this is pretty noisy - not worth looking at?) Akasa Ultra Quiet 400W Paxpower Active PFC Hiper Type R modular (prolly 400 or 480) Seasonic S12 430W Silent ATX2.0 Power Supply (is it REALLY silent?) What do you chaps think? anything i've missed out on? As you can probably tell, price IS an issue here, i'm not prepared to spend more than say £60 on a PSU, but if the right one is £65, then i'll consider, i am a geek after all. So for me, numero uno consideration is NOISE, second, POWER, third, PRICE.
