Default Re: can I use a 430 watts PSU for GTX 460?

Nvidia's recommend power supply requirements most of times can be overstated. I remember G80 launch back in 2006 when Geforce 8800GTX released and people were worried that it would need a bigger new power supply 550W minimum with 32A +12V rail power supply Nvidia recommended and someone on Nvnews forum tested a Geforce 8800GTX with small 250W power supply with enough ample power and it ran games flawless. I was a bit worried it may not worked with my old 430W power supply with dual +12V 36A rail but it worked fine.

A GTX 460 card use 24A and old Geforce 8800GT card used bit more power 28A accorded to BFGTech, it should work fine as long your power supply can handle enough ample power. Few years ago my mate tried to ran Crysis and GTAIV with Geforce 8800GTS 320MB and the PC shutdown after 5 mins gaming, it turned out that his generic 400W power power supply only had combined dual +12V rails of 18A that not had the enough power to handle a Geforce 8800GTS 320MB which needed 28A. It worked fine when upgraded to new 550W Antec Neopower with triple +12V rails of 54A that had plenty of ample power.
