450watt+ and look for brands like Seasonic, Corsair, Antec or XFX to name few.
Sir, can u please specify the model too. This is my first gaming pc and my dad is also not allowing to buy thats why i'm a bit scared about if something went wrong with my pC and i would have to spend more money on that. Can you please suggest me a decent PSU like if I give a full hard stress on it and it will be still be cool in that situation.
are u sure it will be cool with
Processor - Intel i3 3220 (3.3 GHz Clock Speed) (Ivy-Bridge Structure)
Motherboard - Gigabyte GA-B75M-D3H Motherboard
Graphic Card - MSI R7850-1GB GDDR5/OC Graphics Card
HDD - WD Caviar Green 1 TB Desktop Internal Hard Drive (WD10EARX)
RAM - G.Skill RipjawsX DDR3 8 GB (2 x 4 GB) PC RAM (F3-12800CL9D-8GBXL)
Monitor - Dell IN1930M 18.5" LED Monitor
Optical Drive - Asus DRW-24B5ST Internal Optical Drive
Cabinet - Cooler Master Elite 311 Cabinet
No need to be scared - Seasonic is one of the best PSU makers,
the 520 I linked is a good unit, & 87% efficient, and a 5 yr warranty.
The PSU pulls only the amount of current from the wall that your
PC components require at any given point in time.
So, if you PC is only using 300w then that's all the PSU will deliver.
