1. What is the purpose of the computer? What all applications and games are you going to run? (Stupid answers like 'gaming' or 'office work' will not work. Be exact. Which games? Which applications? Avoid the word 'et cetera.')

Ans: Programming, No Gaming

2. What is your overall budget? If you can extend a bit for a more balanced configuration, then mention this too.

Ans: 45K

3. Planning to overclock?

Ans: No

4. Which Operating System are you planning to use?

Ans: Ubuntu 18.04

5. How much hard drive space is needed?

Ans: Not much, maybe 50 GB, prefer SSD

6. Do you want to buy a monitor? If yes, please mention which screen size and resolution do you want. If you already have a monitor and want to reuse it, again mention the size and resolution of monitor you have.

Ans: No, already got Dell 24 inch monitor

7. Which components you DON'T want to buy or which components you already have and plan on reusing?

Ans: Keyboard, mouse, monitor

8. When are you planning to buy the system?

Ans: ASAP

9. Have you ever built a desktop before or will this be done by an assembler?

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.

It will be a little costly. Any reason for the Intel preference?
It would cost him less. Both G5400 and G4560 cost 6.5k and a 300 series mobo would be around 5-7k.

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.

6 cell battery is rare nowadays. Hell I am seeing 2 cell batteries in low end laptops.

What do you guys think about this laptop

Buy Dell Inspiron 15 5575 Laptop computer online with best quality (Rs.44,190)

This is the only laptop available on that site with 8 GB RAM below INR 50K. I don't need windows, but it look there is no other way. Maybe i could go for a differnt brand laptop if that is better.

Other option is

New Inspiron 15 3576 Laptop

for Rs.43,290, It have i5-8250U CPU, but only 4 GB RAM (4 GB will do, 4 GB extra on Dell 5575 for INR 1K extra look like a good deal)

Overpriced af.
Better to get this (41k - 4.1k cashback):
Asus Vivobook X507 (Core i5-8th Gen /8 GB/1 TB/39.62 cm (15 Inch) FHD /Windows 10) UA-EJ456T Thin & Light Laptop (Gold, 1.68 Kg) Online at 18% off. |Paytm Mall
And then put in a m.2 250 GB ssd like Samsung 860 Evo (or Intel 760p/WD Black/ whichever is cheaper)

How about an inverter for PC? That should give you a back up of 5-6 hours.You can connect your UPS to inverter & you are all set to go.

How about an inverter for PC? That should give you a back up of 5-6 hours.You can connect your UPS to inverter & you are all set to go.

This is what my UPS guy recommended. Is inverter more efficient than a UPS ? He recommended "luminous inverter". One of the positive thing he recommended was fast charging, say you have no power for a day and you get 1 hour power, then inverter will charge quickly, you will be able to get 1 hour backup, if UPS, it take much more time to charge. When i said this to someone who is not that tech, said UPS company like APC knows what is best to charge than local inverter company, they follow best practices.

I am almost sold to "Asus Vivobook X507" laptop.

EDIT: Just called PayTM support, even if i use third party address for them to ship, they don't give me invoice. They will invoice to third party addressonly. I need invoice on my address for tax purpose. Look like paytm is not an option.

Any recommendation from Amazon ?

They already assembled PC and shipped it so i have to live with it.

Ryzen 2200 G have problem running on Ubuntu 18.04, some graphics issue, boot crash with blank screen or some times bad display (half of the screen deformed). To fix i had to use ubuntu mainline kernal 18.04, now my old data drives (zfs) won't work.

Abacus Peripherals Pvt Ltd – .

They are delaers for ZION RAM, that is the reason why they give me that RAM. Asking for some other RAM may not work as they are the dealer for this. I am thinking of getting another 8 GB RAM so i can run some VMS in case needed. Currenly the iGPU take 1 GB of RAM, so only 7 GB available for OS.

Tax extra.

Well, nobody even mentioned Zion or this dealer to buy components from.

It was my mistake, i asked the guy who fix my PC. He work for them, so he suggested me this RAM. Being in a rush and confused state (Laptop or Desktop, Should i take new PC or Keep using old PC, But a new UPS or Inverter, etc..), i said OK.

Now i have to be happy whatever i have. So far everything works good. Only problem is Ubuntu 18.04 support, that can happen with any new hardware, i have to wait for the hardware to properly supported.

Don't worry..Zion is not a bad ram. It will do the job for your pc . You don't need Corsair or other higher end stuff.
I used to deal with Zion ram and we had low failure rates.

I had a GTX 750 TI on my old PC. If i want to use it on my new PC, i need a display card on old PC as the mother board don't have a built in grpahics. Is there any cheap display card available or i have to buy a graphics card for it ? Other PC don't need any good graphics, just normal work.

I see Nvidia GT 710 for like 3K, for that price, i am not sure if buy it or add another 10K and buy a new GTX 1050 TI for my PC as GTX 750 TI is 3 year old now.

GT 710 and GTX 1050 ti are miles apart in terms of performance. Frankly, shelling out 3k for it is not vfm imho. Check online for some cheap second hand GPUs.

Yes, i don't need a GPU on that PC, since mother board have no graphcs, i need something so display works. Is there a cheap option, i remember there was something called VGA card before, not sure if anything like that available now.

He wanted to replace a laptop, not a raspberry pi. Also, those desktops would usually come with a 768p TN monitor, OEM PSU and only 1 year warranty.
BTW, OP has already made a purchase.
