The 520W is sufficient. However, I would suggest you to top up just a bit more and go with the 620W instead. Saves you the trouble in case you plan to upgrade to a more powerful GPU in future.

Ok thanks. Hope my vendor allow me to change it to 620W instead of 520W PSU else will stick to 520W already

Oh man... Only have this both ready stock... which is better? Thermaltake Smart SE 630W 80Plus Bronze OR XIGMATEK Vector S650 80Plus Silver? Or should I stick with Seasonic M12 II 520W?

how to define how much wattage psu needed for each rig
sorry im a newbie here

simple

1. how much power does your CPU, GPU, HDD, etc etc needs?
2. check each power requirements on the following items to get an idea on how much power is required
3. for eg. i7 4790 eats a maximum 84W, GTX760 eats max 175-180W, average consumer HDD about 5-10W or so
4. add them up and youll have an idea of how much power it theoretically consumes (bear in mind most of them never actually reaches the peak TDP constantly)
5. now to PSU part, how to pick the right wattage
6. check the brand for reliability, then check the labels on the PSU. see whether does it provide a stable supply at load. do own R&D on how to read and understand PSU labels
7. then pick the correct wattage based on what you have already learned and understood


or in short, most manufacturers already put recommendations on how much wattage PSU is required for that particular PC hardware. say like a GTX760, Nvidia already said it requires at least a 500W and above PSU with decent ratings

seasonic 520w much better.

Thanks. I have chosen Seasonic...

Hi. well if u have time, u can also use the http://pcpartpicker.com/

Just simply pick the parts of your pc that u'll be going to use.

In there, the wattage of items u pick will automatically calculated, hence can give u estimated wattage needed.

Here's example of it.

can i make it simple if i get the biggest wattage for my build?

thanx for the link bro
cheers~
anything ill bug u guys again

you can, it all depends on how much budget you have

you can even go 700+W for a single GPU, although thats a waste of extra cash

most single GPUs require max 550-600W only, so pick several reliable PSUs at this level and youre good to go

I'm currently in the midst of building a rig with i5 processor, dual channel RAM and a GTX 760/R9 270 graphic card. I was thinking of Corsair VS650, or is VS550 suffice ? No intention of SLI or CrossFire near future, but maybe running 2-3 monitors later on.

VS550 is enough since GTX 760 didn't use much power, although I'm a little bit skeptical of its build quality ( take my words as a grain of salt ).

What do you mean by 'its build quality' ? You mean the GTX 760 build quality ?

The PSU..get Antec VP-550P 80+ Bronze RM199 instead..better. Or the 650W version. *don't know the price,can't load the price list..*

Antec 650W is RM259. Seems like the price is more or less to Corsair VS650 RM229, but VS650 is single rail +12V.

The VS650 is actually a pretty good PSU, though it does come with lower tier capacitors (from the review of the 450W model), however the product is well warranted so I do not think it is much of an issue anyway. As for single or multiple rail, there has not been conclusive evidence that one is better than the other, so any would do. I am not sure what series is the Antec model you've mentioned, but the EarthWatts Platinum model is quite ok too. Alternatively, do also consider the FSP Raider which is around the same price range.

Sorry, I meant VS550. My previous post is ambiguous.

Antec previously mentioned was VP series. Regarding single or multiple rail, I understand that there are multiple rails PSU more reliable than single rail, but along the way, it has become somewhat personal preferences. I think I'd settled with FSP Raider 650. At the same price range, it offers higher efficiency, 80plus silver certified, and single rail +12V. Thank you.

guys, which psu is better suited for this rig?

CPU:Intel Pentium G3258 LGA 1150 -->gonna OC to 4.7ghz or 4.8ghz later
Mobo:Asus B85M-G
Zotac GTX770 2GB DDR5 256BIT (ZT-70301-10P)
Ram: Kingston hyper X fury 4GB 1600mhz x2
HDD: WD Blue 1TB
Monitor:Dell S2340L
Custom CPU Cooler: Cooler Master TPC 812 Vapor Chamber

currently i have few options,
PSU: Super Flower HX600M Modular 80+ Gold Power Supply - RM295
PSU: Antec EA-Platinum-550-NC - RM299
PSU: FSP Hexa 550W - RM159
or is there other PSU that i should go for?
