300$ in upgrades. HELP =)

well... i bought all of it today... i actually didnt get that suggested psu..... updated on what i bought is posted.... bought a psu, cpu, and case from the after christmas newegg sale... looks pretty good to me
 
The Coolmax power supply is garbage. I would recommend returning it, but at this point, it's really up to you.
 
something tells me its not garbage... 5 eggs? ill try it out neways... it has a 3 year warranty so i'm not too worried

And that's the main reason why newegg reviews for PSUs should be taken with a huge grain of salt. A good majority of them are written by noobs, newbies, idiots, ignorants, retards and general dumbasses when it comes to PSUs.
 
well i'm gonna at least try it out, and that one suggested wasn't such a good deal... the shipping was 10 day shipping for free, 10 dollar for 5 day, and 20 for 2 day... so it was going to be spendy.


otherwise, for 90 bucks what would be better... it seems like 550w isnt very much.
 
Yah, most of the people who post reviews on NewEgg, when they receive an item and it just plan works for them, they give it 5 stars already. When they find out the component works, they are happy and automatically give it 5 stars. They will not explain in thorough detail on why it deserves a 5 star rating.
 
If 550 watts doesn't seem like much, we wouldn't be recommending 550 watt power supplies... don't you think?

But since you won't listen to me....

Remember that wattage doesn't mean as much these days. What matters most is where those watts are being delivered. For current rigs, it's all about how much amps are on the +12V rail since most PC parts draw their power from there. The more amps you have, the more upgrades (hard drives, video cards, PCI cards, etc) you can add. You determine the amperage on the +12V rails by first finding out what's the total combined, max load, combined or max wattage aside for the +12V rails/section alone. Then divide that total by 12 and you get how much amps the PSU has on the +12V rail.

That's the correct way to find out how much amps a power supply has. Don't add up the amps on the +12V rail to figure out the amperage. Doesn't work that way. If the total combined or max wattage can't be found on the power suppply, check the manufacturer's page for that PSU for that info. If the manufacturer doesn't provide that information, it's generally a good sign for you to drop that power supply from consideration.

However, amperage isn't the only consideration when buying a power supply. You should also look at quality. Though amperage does sometimes help determine the quality of the power supply.

So to illustrate both points, I'll be using two similarily priced power supplies for comparison:
- Apevia RP600V2-S-SL-S 600W PSU
- Corsair 450VX 450W PSU

Both power supplies can be had for around ~$80 at the time of this writing. Though a little shopping around should yield lower prices for the Corsair.

Now I'm betting (if you're a newbie) your first choice would be the Rosewill 600W PSU since it has more power than than Corsair 450VX right? Wrong. Remember what I said about the amps on the +12V rail?

Check out the power distribution of the two power supplies:

Apevia 600W PSU:

Corsair 450VX:
corsairVX.jpg


We can see that the Apevia 600W PSU has 35A (430W/12 = 35A) on the +12V rail while the Corsair 450VX has 33A (396W/12 = 33A) on the +12V rail. Yes it looks like the Apevia power supply wins, barely. However, look at the wattage of the two power supplies and well as the Corsair VX550 PSU.

Notice how the 450W Corsair 450VX has almost the same amount of amps that the Apevia 600W PSU has? Also notice how the Corsair 550VX 550W PSU, a power supply with 50W less than the Apevia 600W, has 40A on the +12V rail. See the disparity with the Apevia?

The above should tell you off the bat just how high the quality of a power supply is. The Corsair 450W PSU only has 2 amps less than the Apevia 600W while the Corsair 550W has 5 amps more yet is of lower wattage. Whenever you see a high wattage power supply with +12V amperage close to or beaten by a lower wattage power supply, that should be an automatic indication on the quality of that power supply in comparison to a similary priced or size power supply.

The BFG LS-680 680W PSU can be had from Newegg for $95:

The Corsair 650TX PSU can be had from newegg for $100 w/ free shipping:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005

Out of the 61 PSUs with APFC in the $75 to $100 price range on newegg, the above two PSUs are the only ones that I'd recommend for the money in that range.
 
ok well i think i'll go with the corsair one... maybe i'll get lucky and get the rebate on it then too.
 
i went ahead and got the corsair one... i didnt want to wait to long and miss out on having it arrive same day as the rest of my stuff thanks for the heads up before it was too late
