New build - is this PSU enough?

[kripper]

Hello,
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.

Please help and thanks in advance.

460 watts should be enough for a system with a 5670, as those don't use much energy. But if that particular power supply is faulty, old or just a bad power supply then it could be causing problems.

The ATI Radeon HD 5670 with its Maximum board power of 64 Watts gets all of its power through the PCI Express slot.

Your system configuration shouldn't be drawing any more than 18 Amps from the +12 Volt rails.

The FSP460-60GHN claims a maximum combined +12 Volt load current of 28.5 Amps.

If the power supply is working properly it is sufficient for your system.

What is the brand and model number of the mouse?

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.

The mouse is Razer DiamondBack 3G, but I used exactly the same mouse on my old pc and never had any problems.

I had the same problem back on 6600GT (or 7300GT can't remember) but updating drivers fixed the problem.
It's like it never stutters, only slows down the game.

460W is OK. Make it 500W, just for safety.
As for the brand, get a decent one, like Seasonic. Believe me, you don't want to go cheap on your PSU.

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 ^^
