Is there a decent 500W PSU somewhere for 30-40$? My current is a 5 year old 400W so a change is needed. Any help is appreciated.

More about : 500w psu

yep. never scrimp on the psu. you dont want to entrust a £/$500-3000 system to a £/$20 psu... as your looking to spend dollars then newegg has some very decent 550w psu's for 60-80bux.

seasonic are the better brands to look out for. you may pay a little more but you get so much more protection for that little extra.

What is the system configuration that this PSU is going to power?

For a system using a single GeForce GTX 650 Ti graphics card NVIDIA specifies a minimum of a 400 Watt or greater power supply that has a maximum combined +12 Volt continuous current rating of 20 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector. NVIDIA's recommendation is based on an Intel Core i7-920 system which consumes more power than most current mainstream systems.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock you are trying to achieve.

What is the brand and model number of your current 400 Watt power supply?

If it's something like one of the following then you don't even need to upgrade the power supply unit at all since these have a maximum combined +12 Volt continuous current rating of 30 Amps and have one 6-pin PCI Express supplementary power connector:

Bestec ATX-400GW S1R
Delta DPS-400RB A
Hipro HP-E4008FWR

Thank you for the info. It really is appreciated! :D  I have Delta DPS-400RB A. Is it still recommended that I get a new PSU? The fan is refusing to start with the system. Had the same problem before, took it out and blew out a clump of dust clogging it. Worked fine for 5 months until now. I blew it out again while it was still in the PC case but that didn't do anything. Might take it out again and see if any more dust is causing a problem. What else could it be if nothing is clogging it?

Btw, I did get it to start but I had to spin the PSU fan with a pencil. After that, it works fine til I restart my PC.

No on Coolermaster, many of their models are junk.
They have at least 11 models on johnnylucky.org

You're having problems with the PSU's cooling fan. If that is the only problem with that PSU and you don't have the knowledge or ability to replace the fan then you will need a new power supply. Without an operational cooling fan the PSU will overheat and shut down or burn out.

The minimum I would recommend is the following:

The Corsair Builder Series CX430 (75-001666 / CP-9020046), with its maximum combined +12 Volt continuous current rating of 32 Amps and with one (6+2)-pin PCI Express supplementary power connector, is more than sufficient to power your system configuration with a single GeForce GTX 650 Ti graphics card.

CORSAIR Builder Series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply
