i'd go for Gigabyte Odin Pro 550W...

why? because it has larger current on +5V and +3.3V, even though slightly lower than CM's +12V rail @18A, but still, it has 4 rails unlike CM's; only 3 rails

i'm just doing simple web-research, not base on experience with it... , actually my brother using Gigabyte Odin Pro 550W, and it's a good PSU with acceptable noise, wait... noise? yeap... i found that it's louder than my ST56ZF even though my ST56ZF using 80mm fan , about that CoolerMaster... no idea...

told you le... at least 30A on single¹ or total combined²

¹ : applied single rail PSU
² : applied on multi-rail design PSU

pardon me for mis-understood that...

so, it's 18A + 18A = ±36A , do keep in mind, in multirail configuration PSU, the total combined rail is exactly as after we totaled up... it's less than that..., not much though... 2A ~ 4A only

what do you how far can a mid-range power supply go... , if you meant mid-range @RM300~RM400 price range then i might suggest Gigabyte Odin series 550 to name a few, Silverstone ST56F for example...

, AFAIK, we don't have Zippy distro, but i think i know someone's gonna bring in the PC P&C , can't tell though, it's only too early to tell

1kW PC P&C too much le... i mean, it's 80mm fan surely as loud as Delta screamer (eh... they using Delta fan anyway (IIANM))

@Evil Oracle
Tagan... enough said, since you only mentioning those 3 brand...
state your budget, most important thing... your current PC specs, future upgrading if any...

18A x 4 = 72A le... and do keep in mind, multi-rail design isn't exactly total combined rail, minus ±2~4 unlike single rail, there's no ± and single rail always better than multi-rail design...

, you got the point there...

in that case yes, but for those multi-rail design - the total likely total combined ...

perhaps me myself outdated, , it is work that way - used to be but depending on how many actually rail/s on , like some other PSU got 2x giant rail distributing to multi-rail and some gigantic single rail - the one and only... and this is the best design... not saying this brand bad, this brand sucks... but i'm just saying about the rail design... gosh... i'm single rail freak le...

@arafat
i think it's your PSU, kindly ask your friend unplug all unnecessary device such as ROMs, extra HDDs if any, FDDs, downclock if overclock see if any change

i think it's your PSU, seriously... 480W, CoolerMaster Real Power (right?), and the rail isn't good enough... 16A + 15A isn't exactly 31A, it could be even lower than that... or worse... 20A

my Silverstone ST56ZF 560W have that buzz sound, but my PC Power & Cooling 750W doesn't even have that sound...

@lichyetan
try remove/unplug one of your HDD, ODD and use single module (RAM), i used to do that way when finding if any PSU related

PC Power & Cooling 750W untuk kemenangan mutlak , big fat single rail, non-modular design... meets my personal requirement when getting a PSU

nah... it's just marketing gimmick... i even use my "SLI certified" PSU on my crossfire setup... no difference what... like i said earlier... it's just marketing gimmick...
