So I have just built a computer about 2-3 months ago and just got my first problem with it. I think it is with the psu. My Psu is raidmax rx-420ks. Every once in while (1 out of 4 times) my computer will make a loud noise. Like when a car starts up and then after i login and programs open its gone... What seems to be out ofline???
So is it just right when you turn the computer on?
A powersupply isn't something you want to be cheap with. If something happens with it, it can kill your other components along with it. Get an 80 plus bronze certified PSU, preferably from Corsair because they rule the PSU world.
I don’t use one myself but many people here say Seasonic is a very good brand. Even the boss here (Logan) gives them a thumbs up. Again I am going to repeat you must go for an 80 plus bronze minimum power supply. I use a Cooler Master 850W silent pro and it comes with a 5 year warranty, is exceptionally quiet, and is 80 plus bronze. You must never cheap out on your power supply. Think of it as the heart of your system and you don’t need that giving you problems. Best of luck, let us know how it works out.
Well, I'll expand on this, it is actually SeaSonic that rules the world, as the good Corsair PSUs are actually built by SeaSonic and just branded as Corsair, same with many other brands like XFX.
Thanks!
it's normal for your computer to rev the fans on startup, most of them do that.
^ yeah.. I would like to say that my computer is quite loud on start up, but after about a minute it calms down. This is especially the case for me since I installed an H80. You said it only calms down after you log in and let things load, but have you ever just let it sit at the log-in screen for a minute or two and see if the fans calm down regardless if you log-in or not? If they calm down even if you don't do anything, then I wouldn't worry about it, but I still highly recommend getting an 80 plus bronze certified power supply when you have the chance.
There is a slight confusion in this thread that I wish to correct.
First off, regarding the "Seasonic makes all Corsair PSU's", that's not entirely true anymore. Basically half of the Corsairs units are made by CWT, the other half Seasonic. This doesn't mean the CWT units are bad though, they're not.
Now the bigger confusion here seems to be with the 80 plus certificate. By todays standards, it doesn't make sense to say "go for a 80+ bronze certified PSU, that's guaranteed quality".
Efficiency is a measure of how much energy goes to waste in the AC/DC conversion done by the powersupply. A comparison: You have two powersupplies, one is bare minimum 80+ Bronze certified, meaning 85% efficiency at 50% load. The other is bare minimum 80+ Platinum certified, meaning 92% efficiency at 50% load. Let's use 250W as the 50% load in this comparison. When the Bronze certified PSU is providing your hardware with 250W power, it's drawing (1/0.85)*250 = 294 Watts power from your outlet, 44 Watts is wasted. When the Platinum certified PSU does the same thing, it draws (1/0.92)*250 = 272 Watts power from your outlet, 22 Watts is wasted. So a higher efficiency means you get a lower electricity bill. I want to add though that you need some serious uptime for the computer to actually be able to notice the smaller power consumption. The main reason to recommend high efficiency powersupplies is the fact that they run cooler and with less noise.
Today most manufacturers can make powersupplies that pass the 80+ bronze requirements, but that doesn't automatically mean it's a good powersupply. What really matters is the stability of each voltage rail (when the load changes, the voltage shouldn't vary), and how much ripple it produces (ripple is basically unclean voltage).
