Well I recently won the Mushkin HP-550 psu from XS a while back. its an amazing looking unit, but its built by top power and is lacking in perfomance.
It has all "asia X" brand capacitors, which I will be replacing with(thanks to arrangement with Trodas ) with
UCC
10v 3900uF KZE
16v 3900uF KZE
200v 1200uF SMQ (x2)
1. any comments on cap selection?
i picked them due to their relatively low ESR and highest ripple current while still being decently priced.
2. This psu also seems to lack good AC filtering, so I have added a RFI filter i got from a psu i had scrapped. but there is more i can do. i was wondering if i should add a dual choke on the input AC like i have on my antec. (what effect does it have mostly though?)
3. What other componets can i upgrade? i have a bunch of psu's and monitors that have spare parts, i was looking at adding the missing componet that can be seen in the photo.(photo was borrowed from jonnyguru's review of the psu, link is further down.)
4. what exactly is it and what would its effects be?

5. does anyone know what the VR's on the railfusion pcb would be for? they dont seem to adjust voltage.
6. the psu has no voltage feedback on any of the rails, so is there a way i can mod the psu to raise the rails?
im planning on powering 6 hdds, highly overclocked and vmodded x800pro, highly overclocked a64(vcore at 1.9v)
all fans and pumps run off 2nd psu.
i figure if my antec truecontrol 1.0 can handle it, this psu once its beefed up should be able to handle it. not to mention my antec has 3+ years under its belt at almost always 24/7 useage(fujiyhu caps still good though)
