I need verification with what my machine will require.
Mobo: MSI P55-CD53
GPU: Twin Frozr II GeForce GTX 560 Ti
CPU: Intel i5-650
HDD: 1x 7200rpm
Fans: 1x 80mm, 1x 92mm, 1x 120mm.
Memory: 4x 4GB DDR3
1x CD drive
Provided that I'm looking for the PSU to handle peak load along with some allowance for future upgrades and a longer lifespan under frequent use, I got something along the lines of 600-650w with a minimum of 38amps. If this information is incorrect, please feel free to correct me as I have no knowledge outside of what I have read.
Previous PSU dimensions: 5.9"(W) x 3.4"(H) X 6.3"(L); fits the case well, but provided the distance between screws is standardized (~5.5" x ~3.5") it has room for a slight increase in width and length.
Also keep in mind that I live in a desert, which means that it can get quite hot around here (although we try to keep the inside cool), with dust storms happening about every month. If you also recommend attaching another fan to my case because of this, that can be done. (Note: I do make sure that the inside is kept well)
With all of this information, what would you recommend for a new PSU? (provided my information is correct)
