May be you are right. Actually I am not that much aware about the PSU thing, although I know it is one of the most important5 parts of PC. I suggested the Zebronics PSU considering its price tag.
Krow it will be better if you put a basic guideline about PSU, like Power rating, Current rating in Ampere, voltage etc.
The PSU is the most critical component of a system. I am saying this, because a bad PSU or mismatched PSU is the ONLY component in a computer that can cause damage to itself and this propagates to other parts also getting burnt out.
Imagine it as the heart of your computer, which feeds clean blood (electricity) to your system. If this is bad, the whole set up can be in jeopardy.
See the following scenarios:
1. Slow processor: System runs slow. Applications take ages to execute. At times the system will hang, and then you can restart it. No harm coming to the system.
2. Less RAM: System will take a while to boot. Multiple applications will cause system to hang. Again you can restart the system. No harm.
3. Low end GPU: Games will render slow. Might not load at time. Games will crash. Again no harm to system.
4. Bad HSF/Incorrectly mounted HSF: The processor will quickly get hot, and start to throttle. It will follow (1). If not OC'ed no real harm. The processor will keep shutting down to protect itself.
5. Bad PSU: During load, it falters, and starts to supply non-smooth current to the components. They start to heat up. Initially the system will "hiccup". Run -- get stuck --- run. Then slowly over time, parts will start to melt, or short circuit.
6. Underrated PSU for System: System will run fine. During load, it will suddenly stop. You will get BSOD. System lock up. Slowly it will follow the behaviour of (5).
Basically, people should give the most importance to PSU. It is the parameter which
ONE CAN GO WRONG WITH. They do not have a fail safe. A CPU will throttle and shut down. A GPU will lock, and crash the 3D-Rendering, RAM will just --- run slow. Try to keep up. Motherboard..witll continue to function in inefficient manner, BUT a PSU continues to function even if it is bad. And if it is bad --- it spreads the problem to other expensive parts.
Anyone going for >mid-range GPU HAS to give PSU a good/perfect thought. I do not believe in Zebronice/Bijli PSUs (sorry no offense to current users).
