I don't know exactly a lot about PSUs but it's been a while since I put together my rig I just want to know can any PSU fit in any case and all those extra cords are just extra right? I mean like I have an ATX Full Tower and I'm not sure exactly how many connectors I'm using on it so should I just buy that PSU that nerd showed me and it can fit right? I'm a noob when it comes to PSUs sorry.

What does your system hardware look like? That silverstone would be massive overkill on anything you own if you're getting away with using a PSU that came with your case.

No I don't care about overkill that's why I didn't ask about that. Unless its possible that a PSU is so powerful it would fry my older parts because of it giving me too much power which i doubt but if thats possible by all means someone let me know I don't have much hardware its actually a crappy compaq that I ripped out and put in a new case and gave it new ram and a better gfx card. I have two 120mm fans and I think I might have burnt out my PSU over time by just doing borderline power usage. My case uses an ATX power supply will a ATX12V / EPS12V work in my full ATX case and are there any differences between that and and a regular ATX PSU?

I can assure that a PSU with high wattage will not fry older parts, unless you increase the voltage manually. And, wow two 120mm fans in one full-tower case? That's pretty shameful, my Antec 900 mid-tower has four 120mm fans and one 200mm top fan. You might want to consider getting some more.

Extra power = harmless overhead, not enough = potentially fry parts, it's the other way around. One of the main concerns is that you have enough combined 12v amperage for the GPU you're using. This chart combined with knowing how much amperage your GPU requires can help determine that: [WIP] ATX PSU Maximum Combined 12v Ratings - Guru3D.com Forums One case that comes with a fairly good 500W PSU is the Antec Sonata III with the 500W Earthwatts. It has a combined 12v amperage of 34A.

I don't like that most video card manufacturers only give a recommended wattage. EVGA lists a recommended amperage as well.

Ohh, Handy! My new fav distributor in that case!

No, but it is completely useless to buy a PSU that is much too large if your system wont be reaching anywhere near the rated capacity. Its generally best to stay within 70-80% load for best efficiency. Or unless you expect to be adding in a ton of hardware soon I would suggest you stick with something that will fit your system right now. Video cards will be getting more energy efficient so the days of 1kw PSU's will be over (except for those who need to show off their e-peeen)

Currently my system is only pulling 342w, but I'm gonna get another 4890 later on, and later on keep adding some RAM etc. so my PSU is 5-by-5 :)

Overclock that Phenom II/4890 and see useage go up to 500w easily.

Do I seriously need to say it again?
