so u mean to tell me they dont have things like the following psu explanation on the site? because im pretty sure they explain and recommend each type of part.
"What is it?
A power supply unit (PSU) takes AC power from the mains and converts it to clean DC power, usable by your PC. Higher quality PSUs give cleaner power and higher efficiency, and have more protections to prevent your PC from catching on fire and burning down your house. Also, cheap PSUs rarely provide their rated power. A $25 500W PSU is very likely a 200W PSU with a fancy sticker.
Which:
Seasonic (all)
XFX (all)
Antec (Earthwatts series, Neo Eco series, HCG series, True Power New series)
Corsair (TX-V2 series, HX series, AX series)
Silverstone (Strider Plus series, Strider Gold series, Zeus series)
Cooler Master (Silent Pro Gold series, V series)
Rosewill (Capstone series)
EVGA (G2 series, P2 series)
FSP (Aurum series)
be quiet! (Dark Power Pro 10 series)
Super Flower (Leadex series, Golden series)
There are others, let us know if we've missed quality PSUs.
Use a PSU calculator (e.g. extreme.outervision) to determine your power needs and add some headroom. You don't need to worry about getting a power supply that is too powerful. If you get a 1000W power supply and your PC only needs 150W, the 1000W PSU will only supply 150W.
Efficiency:
Nearly all modern power supplies are certified with an efficiency rating, typically the "80 Plus" program. "80 Plus" means that the PSU delivers at least 80% of the power taken from the wall, and wastes the rest as heat. The higher the rating (Bronze, Silver, Gold, Platinum, Titanium), the more efficient the PSU, and the less power wasted. Read more on Wikipedia: 80 Plus
Modularity:
Normal PSUs have all (or most) of the power cords fixed. Modular PSUs allow you to add or remove cords for less clutter and improved airflow, but usually have a price premium.
Warning
Low quality PSUs may not provide the rated wattage, may deliver dirty power (damaging your components over time), are less efficient (hotter, noisier), and can explode (yes, kaboom-style, with fire and smoke).
Low quality PSUs usually cannot provide the rated wattage, since the advertised power is the sum of power on all rails. High quality PSUs are rated by the power on the main rail only, and advertise the "true" wattage.
