About 6+ weeks ago I build this pc with help from another forum:
AMD Athlon II X3 445 /3.1GHz, 1.5MB, 95W
MSI 870-C45 /AMD870/
GoodRam 4GB (2x2GB) 1333MHz CL9 Value
Samsung 500GB 7200rpm 16MB cache SATA-II F3
MSI Radeon HD5670 Cyclone 1024MB DDR5 /128bit/ DVI/HDMI
LG GH22NS50 SATA SecurDisc
Fortron FSP460-60GHN 460W
on the PSU it says:
AC INPUT: 100-240V-,7-3.5A,50-60Hz
DC OUTPUT: +3.3V === 24.0A(ORG), +5V === 24,0A(RED)
+12V1 === 17,0A(YEL), +12V2 === 17,0A(YELL/BLK)
+5Vsb === 2.5A(PURP), -12V === 0,5A(BLUE)
(+3.3V & +5V = 123W Max)
Total output continuous shall not exceed 460 watts
and since I started the pc up I had a problem with mouse/input lag in games which seems impossible to fix by traditional means (been asking and searching since I bought the pc), but someone stated it might be the PSU that isn't enough.
FSP PSUs are a mixed bag. It's not really likely that that would be the problem though. If it was, I would not be looking so much at the 12V as the 5V though.
"Mouse Lag" is an old problem that I would have thought did not exist in this century I recall having mouse lag that was eventually traced to an IRQ issue... not something you should have. I recall some specific game issues more recently that involved mouse lag... but those were attributable to poor coding as I recall.
If you have tried both USB and PS2 mice and had the same problem, I would start looking at the GPU and the GPU power then.
If $$ isn't tight look at the PSU as an investment? The $$ u save on your power bills from a decent 80+ PSU actually eventually pays for the PSU over some time so I would look at the Antec Earthwatts Green series 380-500W 80+ Bronze these days for a quality yet wallet frenly investment ^^
