It's been a while since I have done the mod. Maybe 2 months or so.
My 5v line really didn't increase any, But it didn't drop at all, and my system is pretty much stable for having a "Geriatric" PS ($30.00).
It was very noticeable after I did the mod. System stopped rebooting all by itself. Some other probs disappeared too.
I now have an Enermax , umm, 465P ?. that is gonna go in my H20 rig when it's finished, Then the 2v mod.
It's amp ratings are
MUCH higher than my 300w'r. But I will keep the 5v mod anyway.
If you've read the "Why is my 5v line so low" sticky by Hoot.
You'll see the mod is just an electrical "shortcut" for the mosfets.
It does help, and I do recommend it. It's not the easiest thing, especially if you've got a shaky hand. Just "Tin" everything 1st.
