but u can always increase rm50 to get a real power 450 from CM,it's not bad.
CM extreme power is not pure power.

btw,rm200 is used price,i got friend selling,i can help u.

Well, modular are surely going to be expensive but take a look at those top PSU (especially 1k Watt), they are all non modular.

specify why your tt tough powert 750 wouldnt work, because i have one and afaik, psu dont have any compatibility issues so long the motherboard follows its standard ATX specifications, in which the one you have should be.

Thanks for the advice there.

IIRC, the last time i check about the FSP SAGA, its offering dual 12V rail at around 15A each. So, should be around 30A for both rail MAX. Thats more than what silverstone and CM Extreme is offering. The problem is, is the SAGA a TRUE POWER PSU. Tried searching many places about the answer but to no avail.

As said before, further testing will be done tonight with the PSU directly connected to the power socket (not extension anymore) to see whether problem persist. Then, switching to another extension will also be done alongside the suspected faulty one. After that, i might shift to another PSU (probably some chaplang one or get another 400W PSU - the FSP i am asking) and retest again on the suspected faulty connector. If problem did not occur, i will assume its the extension that is causing a problem..
