Ans: assembler

10. Where do you live? Are you buying locally? Are you open to buying stuff from online shops if you don't get locally?

Ans: Kerala, will purchase locally as i need it ASAP, can't wait for online shipping

11. Anything else which you would like to say?

Ans:

Current system i am replacing is a laptop with CPU "1.7GHz Intel Core i3-4005U 4th Gen Processor", that stopped working. I was using external monitor with this laptop. I can use same monitor with new


I am not sure if i get a new Laptop or Desktop. Mobility is not a problem. The advantage i see on laptop is low power consumption. Can we have a desktop build with low power consumption like a laptop ? How about we use a Pentium G model ? I don't need lot of CPU power as mostly i will be using a programming GUI (JetBrain PHPStrom), Google Chrome and Firefox.

New gen. processors are very efficient so you don't need to worry about power consumption I also added a gold certified PSU too for better efficiency

+1 for the specs given above
Do check these hdd's since your consumption will be low
Buy Online Kingston A400 2.5" 120GB SATA III TLC SSD SA400S37/120G In India

Also check cases like Spec-01, 02 to save some bucks.

Are there any problems on setting up server, dB and/or app on Ubuntu/linux cause of AMD processor. Anyone here running these on AMD can confirm??

I read intel generate less heat and less power consumption. I don't have researched on this much, so i am not sure.

It would cost him less. Both G5400 and G4560 cost 6.5k and a 300 series mobo would be around 5-7k.

I was thinking of Pentium G4560. Never know there was G5400.

They are back in stock? Great then. AMD is more future proof, isn't it?

Pentium G stil have shortage, something like 1 year ago, i was going to buy this CPU and was out of stock, i have to buy older model.

How is AMD future proof ? You can use newer gen CPU on same mobo ? I am not planing to upgrade CPU, but since i have other PC with intel, maybe i can swap some component if one die.

better to get a laptop though, for programming.

I am checking this option too. One advantage is if power go, i get backup from the battery. A laptop can last 4 to 5 hours on the small battery it have. Since mobility is not needed, i am ok with desktop, but i want more backup time, i am confused about a UPS, i called local UPS guy for a UPS, he trying to sell me Inverter saying it is better. He told i need a small UPS, then use Inverter so i get 6 hour+ backup (the Inverter setup cost 23K, comes with 200 AH battery). A laptop with small battery give several hours of backup, this is why if i go with Desktop, i need a low power consuming one.

Inverter is going to be cheaper if you really need more backup than a 6-7 AH UPS, but you probably don't need 200AH. A 100 AH inverter will last you 6+ hours if you only run the computer on it.
Only issue is inverters can have a higher transfer time. Also, they mostly lack voltage stabilisation(AVR), though many UPSs lack it too.

A laptop might serve your use case better.

When i called UPS guy, he asked if i have a small UPS, i said yes, he said we connect Inverter to this smal UPS, that will fix the problem with voltable stabilisation and switching time. I doubt he get more commision on it, i wanted APC UPS, he says it is china made and he don't sell to customers. He is APC authrosed service center in my area.

How a small battery in laptop give 5 hour backup ? A desktop PC use much more power than a laptop ? If i am going to buy a UPS for desktop that give similar backup as a laptop, which UPS i will need ?

is power cut a serious problem at your area, and you are looking for inverter for the whole house ? if not, who spends 23k for computer backup lol.

i guess an i3 laptop with 8gb ram around 25-30k is good for your job. @Minion will just suggest you a suitable model. and when you use ubuntu, don't forget to set your snappiness at 5-10.

You will need ~60 AH to match ~4 hours of backup on a laptop. I don't think any UPS will be economical for this.
Laptops have very low TDP and are generally very aggressively throttled to conserve power.
You should be able to get something like a 7100u for ~30k or 8250u for ~40k. Also check if they have a 6 cell battery. Some low power ones come with a 4 cell battery.
