Hey.
My old rig's (now a HTPC) PSU died today, Can you guys please recommend a few reliable but cheap options?
I just moved to a new apartment and spent a pretty penny in the process so I'm looking to spend as little as i can but still not buy crap.
I most likely wont be upgrading the PC so power wise I just need the bare minimum that will handle its current configuration.

Intel D975XBX motherboard
q6600 CPU + Zalman silent fan
8gb ddr2
asus radeon 5670
WD 500gb HDD
WD 1TB USB HDD

Thanx alot.

antec EW 380w $40 out the door
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

corsair 430w $47 out the door - $10 MIR
http://www.newegg.com/Product/Product.aspx?Item=N82E168...


both are the same power wise on the 12v rail but the antec is more efficient (it does not come with a power plug but you can re-use your old one)

the corsair comes with sleeved cables for all its wires, antec sleeves just the 24pin

i would personally go with the antec but the corsair is also a solid unit with a good price

Cheap and decent quality rarely go together...

As far as PSUs are concerned, be informed. Before you buy any PSU read accurate, objective PSU reviews at reputable sites such as www.jonnyguru.com or www.hardwaresecrets.com on the EXACT model PSU that you are interested in as some brands have good and poor quality PSUs.

You can also get an accurate rating of how much PSU power is required for your current or future system at the PSU calculator link below. Once you know the total PSU watts required then you need to confirm that the 12v rail has enough amps. to support your Vid card(s) and the rest of the PC system.

There are several websites that show the Vid card power consumption in watts. Divide the watts by 12 to determine the amps. required on the 12v rail(s). Add 15 amps for the rest of the PC on the 12v rail and you now know the Minimum total 12v rail amps required under full load. It's best to have at least 5-10 amps. reserve on the 12v rail available under full load so the PSU is not loaded to 100%.
It's also worth noting that people often misunderstand the 80% power rating. This is a rating of the PSU's energy efficiency not it's output. 80% plus PSUs use less grid power to produce the same PC power. If it's 80% Bronze, Silver or Gold the cost savings on electricity is pretty small between Bronze, Silver and Gold unless you are paying very high rates for electricity so any 80% rated quality PSU is fine even if not Gold. For those who leave their PC on 24/7 a quality 80% PSU is a good investment.

Nope it just helps people learn to help themsleves and get accurate, objective test data to make an informed decision instead of working with a variety of differing subjective opinions. Obviously if people were to actually read forum STICKIES this would only need to be posted once. ;) 

After doing the research and calculations for countless people in this and other forums I composed the above post to help all.
