I'm having problem finding a PSU, I found this http://www.newegg.com/product/product.asp?item=N82E16817339001 on newegg, wonder if it will work for my system


Spec:

Radeon HD 2900 Pro
http://www.newegg.com/product/product.asp?item=N82E16814102706

Abit IP35-E Mobo
http://www.newegg.com/product/product.asp?item=N82E16813127031

and there are
Sony Floppy disk,
Seagate 400gb HD SATA x 2
Lite-On DVD Writer


if that above PSU won't work, what are some of the suggestions, I'm really looking for something thats cheap
 
I understand your budget concerns. But please please do not buy that piece of crap. Here is why (other than its very cheaply made) and I will try to find you something very close to that price that at least might hold up for a couple of years, give me a hour or so to search.

Look at the label

No combined ratings, here is a cut and paste from another post that explains why this is very very bad. Like I said give me a hour and I will see what I can find that at least we can know what to expect out of the supply. With that one, its a crap shoot.

Here are the more detailed specs, note supply is only rated at a max operating temp of 35C. Well at least they are honest and give it but still no combined output specs.

You have a very powerfull and expensive video card, you need a decent supply, you are in real trouble limiting your budget so severly for a power supply, no matter what I find, its not going to be good or really recommended. If there is any way possible you need to beg, borrow, or , no dont steal, find some way to get more in the budget.

For example your cpu, This is better, faster stock FSB (1333buss) speed and almost the same CPU speed at stock settings. It will OC just as well and save you $50. By raising the FSB just a mesley 10MHz over stock it will run faster than the 6600 and anyway if you run stock the faster stock FSB will get more out of your memory and it will probally outperform the 6600 even at stock speeds. If you plan on OCing some it makes the power supply even more critical.

Actually now that I have noticed that, I am NOT going to search for a POS supply, I refuse to compromise what would otherwise be a nice system by crippling it with a sub-standard supply. Go with the cpu above, that now gives your $75ish for a supply and buy this, $80 after rebate.

I like the Corsair VX series, (disclaminer, just bought a VX550) good value for the money, but regardless you need to check the reviews on JonnyGuru or on the main page here so you know what you are getting. If you do not know how to make sense of the combined power ratings that should be on the label of any supply (if not, don't buy it) there are guides. You want the majority of your power on the +12.


The one you linked, not sufficient info. The question is, if I am pulling say 120W out of the +3.3 and +5 for motherboard misc power and drives etc. how much wattage can I then get out of the +12V rails. Look that supply up on newegg even if you don't buy there as they always have a shot of the ratings label.

From newegg.
WOW you picked the one damn supply that does not have a label shot, hell does it even have a label ?

Going to the Manuf site
http://www.hipergroup.com/English/pr...hpu-4b580.html




.Output Load Regulation
.
+12V 1 & +12V 2 < 360 W
+3.3V & +5V < 280 W
+3.3V, +5V & +12V < 560 W.

less than 360W available on 12V rails, that sucks. Now I might not be reading this correctly, but I have doubts you will ever need that much on the +3.3 and +5, you are looking for a supply that puts out 100-150W on the +3 and +5 and the lions share on the +12 this supply has 360/560 or only 64% of its output on the +12, you want a supply with 80% of the usable output on the +12.

All that said, your stated power supply needs are not that great, and this supply would work fine. My personal opinion is that I do not like that supply for a $100 supply and would not have it, better out there for less or same money. I care not one bit, one way or the other for the cabling scheme I am only looking at the power delivery. You may want the cabling scheme and the value of that to you is not something I can take into account but it does not mean it is worthless. Its a fair supply, if the cabling is important to you it might be the supply for you.


As an example
http://www.newegg.com/Product/ShowIm...W+Power+Supply

140W on the +3.3 and +5, 480W on the +12 and round up to 25W on the -12 and +5 standby,

well the -12 and +5 standby are not pulling enough to matter and if the computer is up and running and is not sleeping its even less so ignore them.

Combined total output is 520W

With this information we can now know that if we are pulling 120W out of the +3.3 and +5, we still have 520 total - 120 = 400W availble from the +12V. This supply is rated lower than that hipro but delivers more on the critical +12V rails used mainly by the CPU and video card.
480/520 = 92% of the supplies power is available on the +12. As you will always be pulling some +3.3 and +5, you will not get that full 480 W, but a hella lot more than the hipro and it shows the supply is designed for the new 12V hungry systems.
 
I absolutly second what BillParrish has stated. Crap PSU's will only bring hardship. I'm sure there are individuals who have survived, but the odds are not with them.

For what it's worth, Corsair VX is a really decent PSU. Also, if you willing to spend a few more dollars, go with a PC Power and Cooling 750 Silencer.

Either way, you really cannot go wrong with those.

Please do NOT skimp on your PSU. It's just as important as the other components you have selected. Blown caps on your PSU (Dead) will be the least of your issues if it takes your CPU / Mobo / RAM with it. Hard drive instability, data corruption.. sigh, the list goes on. It just gets worse if you want ANY chance of overclocking. Also, bear in mind the juice needed to run the 2900XT with a level of stability.

I would go with a 8800GTS 640. If you get lucky, you'll get an A3 core, which overclocks very nicely (mines about equal to ultra speeds, or a bit over GTX throughput).

Skip the E6600. Spend a little bit more, and go with either the Q6600, or the the E6550. If you want to stay closer to your budget, go with the E6550.

Again, please hold what I and Bill have give to you near and dear. A dead system just sucks, and shaving a few bills with a POS PSU is soooo not worth it.
 
What they said. The power supply is the last thing in your case you should go el cheapo on. It is the only thing you can't overclock to make up for other short comings. I'd get the corsair if it were me.
 
you can get that VX550W PSU at zzp for only 88.90 with an additional $20 MIR and free shipping.

EDIT: D'OH! It's out of stock. I guess I'm glad I bought my on Sunday and it's currently on it's way :)
 
Man, even the Corsair VX450 would easily beat down that PSU (and should even be enough to handle the given specs).
