PSU question

Hi, everyone.

I will be building a new PC pretty soon and had a general question about what power supply I should get.
I'm buying a barebones system (case, mobo, cpu, psu, and cooling fans) because it is cheaper than buying all the components seperately. I have hard drives, optical drive, and video card from my last system that I will be installing.

My video card is a GeForce 8300GS, which is a mid-level card. It requires a 350W PSU. The barebones system, without an upgrade comes with a 450W PSU, so that's not the concern.
My problem is, I have been a PC technician for years, but I have never built anything ths powerful. That is to say that I will be running an AMD quad-core (Phenom x4 9550), and 4 GB of RAM. I will also be running two case fans because I really don't want this thing to burn up.

I will NOT be overclocking any of my components. Do you guys think that 450W will be sufficient?

 

Ya, you should be just fine with a 450W PSU but it depends if it's a quality brand name one and not a $10 piece of crap which often comes in bundled systems to keep the price down. Post a link to your barebones so then others can then put their opinions in. Decent PSU's are not expensive, maybe $60 max for you depending where you live. Antec, Thermaltake, are two that I have relied on for years with no issues.

BTW, there are PSU calculators out there where you enter your specs, degree of use for capacitor degradation, will you ever upgrade your video card etc.

 

Here's the link to the barebones kit.

Looks like a generic 450W that comes with it. They do offer an upgrade to a Raidmax 420W dual fan PSU for $10 extra.

 

BTW, I edited my post after you posted. Here's a PSU calculator that many here like very much. I don't know RaidMax so wait for someone else to reply.

 

Thanks, Augie. According to the calculator, I only need ~309W.
I have a couple known good Antec 350W PSU's lying around my workshop, so I will go with the generic one and just replace it with one of my Antec's.

 

Hmm, just make sure you have the extra 4 pin connector cable on your Antec for that motherboard besides a 24-pin main, top right in the pic.

Here's your manual, page 1-13 is for power supply. http://support.asus.com/download/download.aspx?SLanguage=en-us

 

Both the Antec PSU's I have are very modern and do have the 4-pin connector. I was working at Circuit City when they went out of business a few months ago and was able to buy a lot of our tech bench parts cheap.

 

Oopsie, I missed the part that you were a tech, sorry. That's what I get for skimming posts.:-D Enjoy the new rig!
