in need of new PSU, maybe Chieftec 420W

[F_A_L_C_O_N]

I need a new PSU, something with a stronger 5V line

got suggestion on the forum that it could have coused R9800 being undervolted and producing artifacts under full VGA and CPU load, something I would definitely like to remedy

currently 32A on my Enermax, also 5V line is dropping close to allowed 5% deviation when CPU is running on max and probably well bellow with Radeon starting to work

I can get Chieftec HPC-420-302 DF
review at THG
5v .... 40A
and 3.3v+5v is specified at 185W by Enermax and 220W with Chieftec


I guess I could get Antec True power, however only 480W is close to the 40A specs for 5v line and the price is a bit more then 150$ compared to about 80$ (tax incl.) for Chieftec
BTW I am not from US and good PSUs are quite expansive here

so as always any suggestions greatly appreciated
