Hello, I am currently working on putting together my first build, and need some help verifying that my existing PSU is ok for what i want to do.
Essentially, I just want to build a modest machine which will mostly be used for internet, but there will be some editing of home HD movies and some gaming.
My current system is an ACER E650 with pentium D. Definitely overdue for an upgrade.
The case, DVD/CD-RW combo drive, DVD drive, and memory card reader will be reused.
I already had to replace the PSU on this machine and hope to reuse it too. It is an ULTRA LS350. Details listed at the link below...

The new items are:
MSI H77MA-G43 motherboard
Intel i5 3470 CPU
Kingston HyperX 1600 DDR3 2x4GB RAM
Crucial 64GB SSD
WD Caviar Blue 500GB HDD
MSI GTX 650 GPU
(Just a note on the GPU, Im kinda loyal to NVidia and will only be gaming at 1368x766. Based on that resolution and my power constraints, I'm sure this card is good enough for my needs.)
As for the power supply. I am convinced it is a quality unit. It has lots of features that this forum says to look for (over voltage protection etc... and the stated wattage makes sense). However, it is only rated for 18A on the 12V rail.
NVidia recommends 20A on the 12V rail to use the GTX 650, but I am having a hard time seeing how this build requires that demand.
The i5 3470 is rated at 77w and the GTX 650 at 64w. Roughly speaking, this will be a 13A draw on the 12V rail.
Will the rest of my components really add up to another 5A (60w)?
I know the simple answer is just upgrade the PSU anyways since its the heart of any machine. But 1), I feel i already have a quality unit, its just rated for low wattage. and 2) If i upgrade the PSU, ill also be tempted to spring for a bigger and badder GPU, and i am just not interested in adding another $100 or so to this build.
Also, should be clear from my build, i am not an overclocker.
Thanks in advance for the advice.
