One more thing I want to point out is that some manufacturers such as Dell will still sell you extended warranty as long as you purchase it before the original warranty runs out. I don't know if they jack up the price, but that's an option for those who aren't sure - don't buy yet, and buy later if you change your mind.
your credit card may automatically extend the standard 1 yr warranty to 2 yrs.
Very GOOD point! :thumbsup: I've done that on big purchases (my first 42" LCD HDTV at around $1600 years ago) since my platinum MasterCard does that.
Are these parts enough reliable with a minimal risk to see a part broken between 1 and 3 years old ?
Check the manufacturer's warranty, the likelihood of something failing and the potential cost of replacement.
Case
Cooler Master 690 II advanced USB 3.0 Noir
What can go wrong in a case? You might wear out or break the power button or USB ports (especially if you have a toddler that might grab stuff sticking out of them) but otherwise there's nothing to break.
Power Supply
ATX Corsair 650 watts Tx V2
This will already have at least a 3 year warranty, if not longer. By the way, this PSU is overkill for your parts list. With a Radeon 7850 you can go lower on the wattage and still have a lot of overhead.
Procesor
I5-3550
3 year warranty. By the way, why not a 3570K? Your motherboard will thank you.
Motherboard
ASUS P8Z77-V LX Z77
3 year warranty.
Graphic card
SAPPHIRE PCIE RAD HD7850 2048M LITE DDR5
This isn't that high end a card, so if it breaks outside of warranty then you have an "excuse" to upgrade. And by then, the latest cards will probably be much better.
Hard disk
SATA3 1 TB SEAGATE 7200,12 64m ST1000DM003
1 year warranty.
128.0 CRUCIAL SSD M4
3 year warranty.
memory
KINGSTON HYPERX GENESIS 1600 MHZ DDR3 8 GB kit
Lifetime warranty.
Optical drive
DVD RW LG GH24NS90
Who cares? I can buy a replacement DVDRW for the cost of two fast food meals.
Exploitation system
WINDOWS 7 Home Prem x64 Francais OEM
There is no warranty on software, only EULAs.
Keyboard
KB Generic USB/PS2 Noir Francais
Generic keyboards are even cheaper than optical drives, plus if it breaks you have an excuse for a new one. Keyboards do show wear after time, so consider it something that wears out.
Mouse
Souris Logitech Optique B100 USB oem noir
Same thing with mice. By the time it breaks, it will probably be showing wear so may as well buy a new one.
Monitor
ASUS 21.5'' VE228H/2 LED 5MS Noir 16:9 Haut
Probably has a 3 year manufacturer's warranty.
