PC hardware forum: Is this PSU powerful enough?

Sorry didn't realize i forgot the link. http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.1131482

Well I don't find an independent review for that psu so I'm left to guess.

Could be good........could be junk.

It's not what I would get but it's your machine and your budget.

I'm not sure why I posted a bundle, I don't need a case. Anyways here's the PSUs link

It doesn't inspire confidence or provide margin for deterioration or expansion.

Did you look at the expert tech ref provided. If not, you're shortchanging yourself about why all PSUs with the same wattage are not alike and what you should look for in a good PSU. A good PSU should give the rated output in watts on the 12V line alone and 80% efficiency too.

All thinks considered ....I wouldn't put the one you linked in any system I build and I've built a lot
I want to put a system together and never have to open it except to clean it out or add/change components.

Hi Crusifi6 !
I sugest you not to buy cheap PSU, you have Intel i3, 7870.... this computer is not cheap... and low end psu can destroy all that... better save money and buy a quality PSU.
I dont say it wont work with cheap one , but in first case of bad input voltage or overvoltage your psu can fail and destroy other components! Very important features that one quality PSU can have:
Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP), Over Temperature Protection (OTP) and Short Circuit Protection (SCP). Also i found info on 7870 chip and it consumes between 250-300W of power when under load and 100 W when idle. (tom's hardware site) so 500W with 80+ bronze certificate (80 % efficient) and single rail 12V - 30 A. i found one for u , take a look :

It costs around 90-95 USD (check yourself, this was on amazon.uk (53 GBP))

Hope this helps!

If I want to have a power supply last a few years I take the total Watts and double it. WHY?

Because Electrolytic Capacitors degrade over time. Push your PSU, add heat and that part wears out faster. It's like your car. Let's put it on the track at 100MPH and how long will it go compared to 75?

Why are you trying to "get away"?
Bob

Well my calculations would be that i would only be using 250 - 300W with my set up. And that's at full performance.

Also I'm not trying to get away, I just have a budget since it's not my money. My parents are buying me a R7870 for Christmas so that's why I need a new PSU. And with the R7870 being at $250 i don't have much room to work with. The next low price, well rated 500W+ PSU is in the $100 range.

Not only did you figure out the conversion losses but to go any further to see what we can get away with we have to look at RAILS. Specifically how many and what number of Amperes will be on each rail.

This is another reason I'll double the number and get a single rail PSU. I can pick my PSU out in about a minute this way. I'm sure folk could spend a few weeks on this one.
Bob

Like i said the 500W and up are all in the $100 range - out of my budget (not even my money remember.)

Anyways i got some disclosure from http://teksyndicate.com/

Thanks everyone for helping me.

I realize a budget is at stake here. But, take the advise even if you get a 500W PSU that delivers the goods, it may not for long. If you get it all together and it works, wonderfully, it may only for 90 days or less. The reason being as stated in older posts, if you push or rely on cheaper(build) PSU it will fail sooner or later flaunter. AND!!! if it does fail may take something with it, to include anything deemed precious to the PC. Thus, get something that delivers well but also provides a decent measure of "excess" wattage so it remains workable even at probable heavy demanding times. If you game "ALOT", that heat stress is very crippling to any PSU. SO, if you can add any $ to your parents wad, do so. Picking up "aluminum cans" or recycling in general can provide some $. Helping a neighbor do something or ask for small wage, all adds up.

FYI- I strip old PSUs of copper wires and aluminium heatsinks and then junk remainder as ferrous metal with other junk. After awhile i have plenty of junk metal to dump the old p/u and get some $. That at least fills the car with gas.

http://www.geeks.com/details.asp?invtid=CP-G1080&cat=PWR is 55 bucks and over 1,000 Watts.

While I bet it would not deliver that continuously I wonder where you are shopping.
Bob

Are you stirring the pot?

Would you put that 'off the boat' thing in your gaming rig?

That and newegg and amazon have supplied a lot of gear for many I know over the years. I wanted to take a quick look at the power supply offerings and for 100 bucks I want a Starbucks card and more.
