I've been gaming on XFX Geforce 8400 GS on my Vista PC having PSU of just 300 watts. I have had no problems till now(6 months on vista).
Should i continue with this same PSU (Lenovo's Default PSU) ?
If in future i have to upgrade my Graphics card (Probably to Geforce 9 Series) then would i have to upgrade my PSU ?
If Yes then, Is the Motherboard came in Lenovo PC upgradable to a higher Wattage PSU ?
My pc config:-
Intel Pentium 4 3.06 Ghz HT
80 gb hard disk
2 Gb dual channel ddr2 ram
XFX Geforce 8400 GS 256 MB
Intel 945 chipset
Windows Vista ultimate SP1
If it ain't broke, don't fix it.
At least not untill you upgrade your system.
Then definatly get a qualitly PSU.
Make sure not to get one of the really cheap ones as they love to fry.
Corsair, PCP&C, Enermax, Silverstone and the Antec Earthwatts line are good choices.
