My PC spec:
CPU: Intel Xeon E3-1230 v2
MB：Asrock Z77 Extreme 4 socket1155
RAM: Kingston DDR3 8GB 1600mhz KVR16N11/8 X 2 unit (16GB RAM)
SSD: Intel 120GB SSD 320 series
HHD: WD 1TB Blue Hardisk
DVD：Liteon DVDRW ROM
Sound: ASUS Xonar Essence STX PCIe Sound Card
VGA: Sapphire HD 6750 1GB DDR5

using 4-5 years old Acbel 510W PSU, already old model.
wanna upgrade my VGA card to R9 380 or GTX 970, and look for single +12V rail. 

Even a 650W is pretty overkill for most single GPUs (with the notable exception that you are going to overclock 290/290X)...

Anyway, the G-650 is aplenty for most single GPU setups.  Heck even a quality 550W unit can power them up pretty easily with some room to spare.

The HD7950 is a pretty high-end card back then - now it's more or less a mid-range card...

My PSU is pretty much silent, with no issues such as coil whine.  It's a fantastic unit, with high quality components. 

saw u are using X series, heard that X alot problem, dont know true or not. 

ur Seasonic G 550 80+ Gold are semi modular? 

I'm planning my rig now and am contemplating on the viability of having a long-term PSU solution, together with the casing.

Suppose that I go straight to reputable models like the Seasonic S12G Gold, is it realistic me to foresee using it for the next 5 years and counting?  That would mean just like Casing, re-using them even I upgrade my specs 2-3 times in the future?

If a PSU can be something like that, I would consider significantly increasing my budget.  If it's something that is 'buy and throw', might as well get Hexa+.

Nope. No issue here. Even overclocked and crossfired HD7870 and HD4870 with that.

Erm... it is a semi modular unit.  You can detach some of the cables, but not all of them. 

now X-series selling RM5xx. 

Quality comes at a price. With USD going up plus GST, it is even higher.

I currently use Aerocool AF-600 for my rig.. Is it bad?

Just wanted some light into this question form senior LYN forumers, is 11.75-11.88 on the 12V rail normal? I thought it should be something like 12.1-12.3? I'm worried it will damage my hardwares on the long run...

Hello, can someone recommend me psu for my system? only using it for gaming.

i5 4690k 4.0@1.08v
Gigabyte Z97 mobo
AMD 7850 (planning to upgrade to 290x)
2 7200rpm hard disk
5 fans

I am currently using FSP Hexa 500w. It is working fine and quiet but I would like to upgrade my psu so I can change my gpu later.

budget around RM370, prefer semi modular or full modular.

thanks!

Buy it asap, price will go up soon due to weak RM 

The Q&A thread was closed, so I ask here:

I see my motherboard has two ATX power cables. One is 24pin, another is 8 pin.

Does that mean my motherboard requires me to plug 8pin also?
Mobo requires that much voltage ah...
