How much should I scale up from that? I noticed the efficiencies of (good) PSUs are a little above 80%, so should I get the recommended wattage after factoring the 80% efficiency of the PSU or just a little over?
Afaik power supplies, transformers, etc. are rated for the power delivered on the output, not the input power required to deliver that output. If it's a 450W PSU, it's supposed to be able to deliver 450W to the computer, drawing 562.5W from the wall if at 80% efficiency at full load or 530W if at 85% efficiency. I think this is what you were talking about, for "factoring the 80% efficiency of the PSU?" Also, keep in mind that PSU calculators are probably some back-of-the-envelope conservative estimates, and decent PSUs can deliver somewhat over their rated value before shutting down.

By decent I think you just mean underrated psus. Corsair is quite famous for it since they want to keep their efficiencies up. They just get a higher wattage PSU and rate it lower.
PSUs are rated for their output, though essentially you can get the amount of power you can expect from the PSU by multiplying the 12V rail(s) by 12 and adding them together.

I'm going to buy a new tower for the release of SC2. The only crucial component for me is an i7 because everything else is upgradable. Can't wait :D

That's why you don't buy generic parts from best buy or w.e that was made in china.
|
In my experience Best Buy normally stocks BFG/Corsair/Antec PSUs with a few shady brands in between.
That said I hadn't stepped inside a Best Buy for like 3 years and just recently saw some of their stock.
|
some best buys acually have some computer parts at competitive prices, like their cpu coolers aren't half bad now or their psu's they do tend to stock antenc corsair and bfg.
Some things like their DVI or Cat6 cables are horribly expensive
Yeah the generic brand i think is dynex which is priced bad for a shitty psu.

That looks like bottom of the case cpu only.
|
Yeah, the case is a p183, so they're compatible. Do I need to add any cables to my build or should everything come with the parts?

Final Build. Yes?
Now to find peripherals...

Your selected power supply has a "1" in place of an "i". Ew. And your mobo supports 6GB/s transfer rate, but your HDD is only 3GB/s. Maybe consider a different HDD?

Rho_ This is just my corsair bias here, but I'd take the 750HX. The CP 850 only fits in a few cases and if you ever decide to change (though if you have a P183 that day might not come for a while), it won't work out. The Corsair also has better efficiency. If you're looking at it from a price point of view, Antec no contest.
tofucake, not a single convential HDD can saturate the full 3GB/s so all of those 6GB/s HDDs are just a complete waste of money. As far as I know, there is only ONE drive on the market that actually surpasses 3GB/s (Crucial C300 RealSSD)

Can you explain your motherboard choice? I can't figure out why you chose that board. It doesn't seem to be particularly feature-rich for its cost, and it's also not one of the cheapest am3 boards, so I can't tell what you're going for.
This is just an example, but I'm fairly certain you can get a build that is either cheaper and does almost the same thing, or one that costs the same but uses slightly better components.

:d if you wanted to take teh cake on quality i'd get a seasonic X fan off = sexy silent.
|
really the fact that the fan doesn't go on doesn't say much. I can never hear my HX650 anyways. I run furmark + prime95 and can't hear the PSU at all even with an open case. The Seasonic is more about the efficiency imho.
nineninja9 that actually is a fairly good board. The 890 chipset comes with onboard SATA III support (though uselses, is a feature), and the board has USB 3.0 running off of some spare PCIe lanes.
The board you linked doesn't even support DDR3 :p
|
Oh wow my bad, I just picked the combo with the cheapest board. I believe my point still stands though. I mean, this is a budget build, I don't see sata3 or usb3 are particularly important features to pay extra for.
|
SATA 3 maybe not, but USB 3.0 isn't that bad.
Also it's generally better to pick the newer chipsets when you can. Better hardware support, and better hardware most of the time as well.
|
I guess so. It's up to the purchaser if it's worth the extra 10% for those features.
|
thinking of sound proofing my rig. what do you guys suggest?
