PSU: Antec Smart Power 2.0 450W

The computer seems to be lagging a bit in games.

Any ideas?

Thanks

A weak power supply should not cause low performace unless the GPU had to underclock. In that case, you should of gotten some form of warning.

So my 450W Smart Power 2.0 is enough to feed my specs?

 

[The_Other_One]

450w should be plenty.

Thanks Man

Btw what does 12V2 Rails mean?
Does it mean 2 12V rails running at 18A?
I m confused, you can help me explain

Thanks

EDIT: can some1 explain these things to me?

There should be a 12V1 and 12V2. Sometimes they both run at the same amperage, sometimes they don't(but just off by a couple amps)

 

[b3atofang3l]

The stats tell me:

12V1 - 17A
12V2 - 15A

so its 32A@12V ramps?

 

[The_Other_One]

Ramps? Hehehe... Yes, 32 amps

 

[Archangel]

hmm... that would depend on the total Wattage output the 12v rails can deliver in total. I dont think it will reach the 32Amp tbh
