New Build under $850 (RAM, CPU, MOBO, PSU)

[Achint2000]

Need all parts strictly under $850 (Rs. 55,000)

I'm sick of my old PSU and mobo not working, so, going to replace them.

Already having GPU, HDDs, CD Drives, OS, Monitor, Keyboard/mouse, etc.

I have an ASUS Strix 970, no SLI and the build is mainly for heavy gaming and being powered on idle 24x7 otherwise.

16 GB DDR4 2400 MHz RAM, must be certified with the motherboard.

6th or 7th Gen Intel motherboard and CPU, which one is better?

(Im preferring an ASUS Strix Board and an i7)

A good reliable PSU which will last long. At least more than 750W and meeting the new build's power requirements.

Also suggest websites I can order parts from. I'm from India. (I'm familiar with www.theitdepot.com and amazon.in)

A 550 watts power supply would already be meeting power requirements, mind.

Here's a suggested ~Rs. 55,000 build, all based on your specific requirements:

Selected Intel i7-6700 (6th-gen Skylake) locked CPU due to budgetary constraints. 7th-gen has only slightly faster core clock speeds than the 6th-gen Skylake for a Rs. 5,000 price difference. Use included stock Intel CPU Cooler to save money, as it will suffice.

Got B250 motherboard (supports both 6th-gen and 7th-gen Intel CPUs out-of-the-box without any need for BIOS updates), preferred Asus model (Asus Strix B250F). Pairs nicely with the locked i7-6700 (or i7-7700).

Chose 16GB RAM (2 x 8GB) DDR4-2400 based on your requirements. This RAM modules are in the Asus motherboard's QVL list, as per your requirement: http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/STRIX_B250F_GAMING/Strix-B250F-Gaming_Memory_QVL.pdf?_ga=1.124579786.1760170017.1490593791

Selected a case, Phanteks Enthoo Pro M, with good airflow and cable management that is compatible to fit all your parts in.

Got a good-quality Seasonic 750W PSU as per your requirement. But in fact, a good-quality ~550W PSU should be MORE than enough. However, the price of the Seasonic M12II-750 EVO is way cheaper than the offered prices of the 550W PSU's, hence, the 750W selection (which is also your preference).

A 550 watts power supply would already be meeting power requirements, mind.

My current build's Corsair GS700 (750+ Bronze Certified) started a burning smell on an idle system after 3 hours of gaming, so you never know. I may have a GPU Upgrade (probably to Strix 1080) or a 970 SLI so I'd like some extra power.

I already have a Deepcool GAMMAXX400 CPU cooler, a thermal compound and I keep my build without a case. A great case though, I'll buy it if I need it later

I upgrade PC parts once in a decade so im considering Intel KabyLake i7 7700K 4.2 GHz (4.5GHz OC) for a performance and a one-time upgrade increase.

For a change in the PSU for ~Rs.1,000 difference, is there any performance/quality difference between the one you suggested and Corsair CS750M 750W 80Plus Gold Certified (CMPSU-CS750M) ?

To balance the budget for the i7 7700K, exchange for the case's price and ~Rs.1,000 decrease in PSU's price will do.

The Corsair CS750M will have no problems powering your rig, yes. Though, compared with the Seasonic M12II-750, the Corsair CS750M is slightly lesser quality in terms of cabling (Corsair has Semi-Modular Cables vs Seasonic has Fully-Modular Cables), warranty (Corsair has 3-year warranty vs Seasonic has 5-year warranty), and OEM (Corsair uses Great Wall as manufacturer vs Seasonic makes their own PSU's). If you feel that the ~Rs. 1,000 is a big impact on savings for other components, then, you can get the CS750M as an alternative. But my personal choice would be the Seasonic. If I would get a Corsair, I'd look at the RM750x or RM750i (with 10-year warranty and are much better quality than the CS series).

However, when you now mentioned you wanted to get the i7-7700K (for one-time upgrade), you would also have to change my initial recommended motherboard (which was the Strix B250F). That motherboard does not support overclocking that unlocked i7-7700K. Following your "one-time upgrade" requirement, it is more logical to pair this unlocked i7 with a motherboard that fully supports overclocking, which as per your Asus Strix preference, the Asus Strix Z270F. The cost of the Asus Z270F is ~Rs. 15,140 @ The IT Depot. I can't find that motherboard in stock at Amazon though.

So, updating the initial parts list based on the changes above, you would look at:

CPU: Intel Core i7-7700K 4.2GHz Quad-Core Processor (₹27672.00 @ The IT Depot)
Motherboard: Asus STRIX Z270F GAMING ATX LGA1151 Motherboard (₹15140.00 @ The IT Depot)
Memory: Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-2400 Memory (₹9155.00 @ The IT Depot)
Power Supply: Corsair CS750M Semi-Modular 750W 80 Plus Gold Certified PSU (₹8190.00 @ The IT Depot)
Total: ₹60157.00

The above build with your updated preferences will now exceed your declared Rs.55,000 budget by Rs.5,157.
