help with choosing a new PSU

bethss1949 · Apr 18, 2013

this is what I have: HP P-7 1414 AMD A-8 5500 APU putting a Radeon HD 7750 D in as the HD7560d is having heat issues CPU=95F /GPU=175F temps while playing The Sims3 + 2 expansion pks for a few hrs. PSU 300w stock. Need suggestion on what is needed in a good price range. will be adding a new HDD as my says "its failing" a couple months ago and yes did complete backup.looking at the Western Digital EW Black.. trying to make sure everything will work together

These would be my top picks

Your CPU temp is fine. Your GPU temp is high. Does your card have a fan or heatsink only?

Yasser's links are good. I wouldn't get the VP450 however. I'd look to the Antec 380W green instead. Better PSU.

a fan also will the antec 380w be enough new card calls for 400w although I know the better the product the better the results

Thanks my friend .. but actually Tom' picked this psu (antec vp450) on it's winner 500$ build in system build marathon.

The stock OEM 300 Watt PSU should have no problem powering your system with a Radeon HD 7750.

The power supply's total Wattage is not what matters. Its maximum combined +12 Volt continuous current rating is the most important requirement that needs to be met.

Not saying the VP450 is a bad product. Just not as good as other options. Yes that one is wattage rated 70W more, but it only has 24W more on the 12V rail. It's also not 80+ rated at all while the 380W green is 80+ bronze. I would rather have a 28A 80+ bronze PSU at the same cost as a 30A non rated PSU. Might take the 450 if it was a lot cheaper. But your amazon link and Newegg show both PSUs to be $40-$45.

will the antec 380w be enough new card calls for 400w although I know the better the product the better the results

The 380W green, VP-450, and CX430 should all have no issues running up to around a 7850/650TI.

I am not at all familiar with the +12 volt stuff just getting into all this upgrading stuff lost when it comes to voltage sorry

will I have enough space in my case for for any of those ATX 15.5" 6.89" 16.5" bays 5.25"and 3.5"

Okay, a quick PSU voltage guide here... The PSU delivers the following voltages to the computer 3.3v, 5v, 5v VSB (always on power) 12v and -12v. Each voltage has a maximum throughput (amps) that the PSU can provide. With the following formula, we can determine the wattage available, VxA=W (volts multiplied by amps equals watts). Since modern computers are very heavily dependant on 12v availability (and graphics cards increase that demand) that is the amperage number we are most interested in.
The voltage requirements have changed over the years and in some cases manufacturers have either resisted updating their designs or kept older designs on the market so users running very old computers can keep them running which is where the concern lies - you really don't want an older designed PSU in a new computer.
I probably just confused you more...

yes but if I read it a few times and do some research I am sure i'll get it thank u much

thank u I have this bookmarked

yes I have the card in and temps r running on average 35-40C I think that's preety good may not need another PSU have the fan at 60% hope that's correct couldn't find any info on what it should be running it at any advise here ??

ko888 · Apr 27, 2013

If your CPU temperature is now running at 35°C to 40°C you're doing pretty good since it's well within AMD's specs for that CPU model.

Which fan do you have at 60% ?
