Alright so I have a custom build from when I graduated high school. It was given to me as a gift from my uncle and ever since ive gotten it I think it needs a new power supply. The PSU is from june of 2009, has a max output of 550w and is really loud. ive even taken the liberty of cleaning it out with an air compressor and a rag for the inside of the fans. however it didn't do much good. These are my specs:

 

Motherboard: ASUS P5N7A-VM

 

CPU: Intel Quad Core Q9550 Yorkfield 2.8ghz 12mb cache

 

RAM: 8gb DDR2 800mhz, ( 4x 2gb sticks, 2 sticks are crucial ram with LED lights and 2 are Patriot or Kingston, cant remember)

 

HDD: SATA Western Digital 1TB 32mb cache 7200RPM

 

Video Card: EVGA Nvidia GeForce 210 1gb ddr3

 

PCI x1 Renesas USB 3.0 Card (2 usb slots)

 

PCIE Linksys WMP600N Dual Antenna Internal Wifi Card

 

Blu Ray internal Disk Drive

 

2 LED Chasis Fans

 

NZXT M59 Classic Series ATX Mid Tower interior chassis

 

-----------------------------------------------------------------------------------------

 

Can I get this computer to run on a 350 W power supply with my current specs? Id like to save some electricity and just run a lower psu that's nice and quiet.

Ok, first off, without known who made that power supply, it is hard to say if loud is normal for it or not.

Second, lowering the available wattage on the PSU will not save you money on the electric bill. Your power supply only delivers the amount of power needed by the system. All else being equal, a 1200watt power supply wouldn't draw any more power than a 500 watt supply on the same system. However, what you can do is buy a higher quality power supply that is more efficient.

 

Here is my recommendation for you, given your machine.

Laptop: Alienware 14 : Intel i7 4700mq : 8GB ram : Nvidia GTX 765 : 256GB Plextor M3 : 1080P IPS display

Test rig: AMD Phenom X4 955 @ 4.0Ghz : MSI 970A-G46 : 8GB Ram : 128GB Plextor M5s : 2x AMD 5770's (Flashed to 6770) : PC Power and Cooling Silencer 750 : Pioneer BR

Hackintosh : Gigabyte GA-H61m : Intel Celeron @ 3Ghz : 8GB ram : EVGA GTX 550Ti : Patriot Torx 2 64GB : Silverstone Strider ES-50 : OSX Mavericks

Ahh, i understand now. that makes sense. however the psu you linked was abit over my budget. i was hoping for something around 45-50 dollars.

Yes that is a perfectly good power supply for a basic PC.  For better savings on electricity, it's the PSU's efficiency that is important.  The Corsair PSU is 80 Plus Bronze certified.

 

The efficiency certifications under this scheme are 80 Plus on it's own, and then 80 Plus Bronze, Silver, Gold, Platinum and recently Titanium (in order of improving energy efficiency).  This link shows the requirements of the different levels.  Gold certified PSU's are quite widely available, but they do cost more.  This is about the cheapest Gold certified PSU I can find at the moment which is just over your budget - http://www.amazon.com/dp/B006BCKDGW/?tag=pcpapi-20  If efficiency is important to you, it might be worth the extra $10 though. It's made by Super Flower and is reviewed here.

Wow, i never knew that. now i actually understand how psu's are catagorized. Learned something new today =]. As for which psu ill choose, ill probably go with the one i found just because its cheap and modular/has good reviews. It should do what i need it to do. Thanks a bunch guys, much appreciated :thumbup2:

I'm using the 600w version of that PSU in my build and so far it's been stable and reliable.  I like that it's modular, and it's quiet, too.
