Well you have to learn somewhere biggrin.gif

Yes, 450W is enough for an i5 CPU and a 7870.

Here is a link to an article on guru3D covering the i5-3570k
http://www.guru3d.com/articles_pages/core_i5_3570k_review,10.html


You can see it uses around <120W. And you know your GPU uses <280W. So all in all you have 400W for your CPU + GPU and 50W for the rest of your fans/lights/pumps/whatever which is more than enough. Especially if you have a very efficient Gold or Platinum rated PSU from the list i showed you. Note; just because it says 80 PLUS or 80PLUS Bronze, or 80PLUS Gold, doesnt automatically mean the unit itself is great (internal component quality). Pick from the list i gave you; the ones rated there are accurate and have prior testing to prove that it is a good unit.

Well for one; you should be taking your information from credible websites and professional reviewers (not just random people) -- im not a professional reviewer and a random but i hope you understand what i mean! rolleyes.gif Try reading stuff or looking for information on questions you have from Hard OCP, JonnyGURU, or even http://www.realhardtechx.com/index_archivos/Page541.htm for your PSU needs. I use realhardtech for all the information and low down about PSU's. The problem with PSU's is that sometimes big brand names will rebrand cheaper/low quality PSU's and just slap their brand name on it and sell it as their product. Thats why you really need to know whats INSIDE the PSU, you know?

Start drawing conclusions based on the actual hardware components; rather than from subjective comments based on people's "experiences" on they believe "might" be true.

Really? Yeah i dont know about that.... Maybe its possible? Normally id suggest a 650W unit for a CF 7870 but thats just based on the numbers i see on reviews.

Yes the list i gave you are all great PSU's with internal components that are tested to be of quality. Just find one thats cheap enough that you can afford and go from there. There is a user here by the name of "shilka" that usually touches on a good majority of PSU threads here on OCN so if you have any more questions on a specific unit you can politely PM him and he might almost always have an answer for you.

Good luck with your build OP thumb.gif Im happy youre not going to be one of "those guys" who are like YO I GOT MY NEW RIG AND MY 1200W PSU for my i5 + single GPU. and theyre like YA MAN MORE WATTAGE = MORE POWAHHHHH gunner.gif But we all know thats not really the case rolleyes.gif You need power to run your components; any more is good for future proof but youre not going to get more FPS from a higher wattage PSU.

I dont know TOO much about it; but i remember reading around from tons of PSU threads here that if you have a PSU with overkill wattage for what is regularly being used; your PSU will actually be running "less" efficient... you have to be withing a certain amount of minimum power draw for the power supply to be running the most efficient. Thats why having a 1000W PSU for a computer system that only needs like 250W idle or 350W load is actually bad; because it is less efficient than having a 450W PSU for a system that requires the same wattage. You can do more research if you want to learn more biggrin.gif

i read that having just that wee bit extra juice is probs the best idea, but i suppose everyone has there own opinions. im thinking it will be a minimum of 500 i go for and a max of 600, that way i know ill be ok for a bit in the future as i dont want to be buying new components every year lol and a new CPU will be next on the list, im happy with the case and MOBO and my GPU probs be luck to get 2years out of that so more cash lol. begining to think i should have stuck with the ps3/4 lol

That's what I think too, that way your power supply will not be under 100% load when you will want all the juice it can give to your pc. The biggest harm an oversize power supply will do is a big hole in your pocket.
