asrock H77M
2x kingston value ram 6gb (2+4)
1x WD caviar green 500gb
1x samsung spinpoint 80gb
Sapphire HD5770

im planning to buy SeaSonic 520w PSU.

next year, i want to upgrade my pc sort of like this

intel core i5 3rd gen
CM 212+ evo
asrock H77M
2x4gb 1600mhz DDR3
1x WD caviar green 500gb
1x samsung spinpoint 80gb
sapphire HD78XX
add : + SSD
+ DVD writer

my question is will my seasonic 520w support my future upgrade? or should i consider seasonic 620w? i already use PSU calculator from google searching but every time i calculate, different manufacturer like cooler master, xigmatek, asus give different total watt.

im bit confuse, hope sifu can help. thanks.

Got Seasonic S12II 520 here?
If you can get the S12II 520, it's enough. You can even power up a 7970/680 with ease, albeit I'd get a higher wattage unit.

Yes, Seasonic 520W definitely more then enough.

Try this bro.

may i know why u would get higher wattage unit?
im afraid if i get higher wattage PSU will overkill my system.

if 520w is enough then i should get this right away.
thank you.

future upgrade

mybe as better gpu.. @ mybe add on more gpu sli/cf later


mostly happen...


so as 6xx-7xx watt is good to buy ..

yes. i already use PSU calculator from google searching but every time i calculate, different manufacturer like cooler master, xigmatek, asus give different total watt. that why i ask here. thanks btw.

sli or crossfire i think is very unlikely because im student, poor.
one gc i think is enough maybe.
what do you think, should i stick with 520w or 600+ watt?

Oh.. Ok. But for your buld the PSU u wanna get is enough. Whats your budget?

my budget is around rm200. i've read in this forum, many people speak highly of seasonic brand. review from google also said seasonic is good. that why i want to buy. im interested with seasonic m12-ii 520. i can topup a bit to get this model.

or do you have another recommendation?

For future upgrades and longevity lo...
Higher wattage units allow the unit to operate at a lower load, making it last longer...
Oh, read this article by me about PSUs

Oh very tight your budget... Then ok la get that seasonic... If me I will get any modular gold 80+ power supply... So you no need to buy again when upgrade... Been using my AX750 in 3 computer now...

Best is just to get 1 step higher than what you think is enough.

caters for degradation and headroom for enhancements. lasts you longer by just paying a bit more.

oh i must have overlooked this thread. will read this. thank you

by 1 step higher, do you mean seasonic 620watt is good for me?

when otai speak up...

yes. that's what I mean.

3 ways to look at things.

1. buy what you think is sufficient.

2. buy something that's 1 notch above what you think is sufficient.

3. take what you need, multiply it by 2 and buy 1 step higher. (ok la this one not necessary la but it's one of the good rule used for buying HDD. to avoid running out of space fast)

a PSU will last longer when it's at lesser load.



either one is fine but if you can, the 620w will give you better value as the higher power rating also means your usage stresses it less.

that additional 60w is a lot of headroom for upgrades or overclock if some day you intend to walk that path.

thank you for your advice. i really appreciated it.
i will look for 600++watt psu.
