think your confusing something if you believe using a 12v 2 x molex connection to a 12v single 6 pin connection will cause cross loading.
biggest issue i see is if the psu can actually supply the required amps for the graphics card under load, and has you've pointed out the specs are 168watts or 14amps which both rails say they can provide, and a total system draw of 30amps on the 12v rails, which that psu can also supply at 34 amps.
yes he may need a better psu but just going by the specs i couldn't say for sure the one he has won't work with the new card for now, so i'd still advise him to try his first then get a new psu if it's not up to the job and shuts itself down because of over current draw.
yes i'd definitely suggest getting a better power supply for the long term but don't see the need to rush if he's tight on funds and his current psu will do for the interim.
think i read somewhere that psu only failed to get a 80% bronze rating because it was 0,03% under or something like that anyway so no idea if it's a poor quality or badly designed psu, can't find a proper review on it by jonnyguru or any good source like that.
