I changed my system recently but left my old psu 400w, its about 8-10 years old so i probably need to replace it, my pc's been switching off and freezing in high load/playing games so im guessing theres not enough power as iv tried 2 hdd and same thing happens,

cpu: Intel pentium g620 dual core 2,6ghz
mobo: P8H61-M LE/USB3
graphics: Nvidia gt 440
memory: 4gb ddr3

got a dvd-rw and cd rom and an old ide hdd, i was wondering if 500w would be enough given nvidia say that for the card its
"Maximum Graphics Card Power (W) 65
Minimum System Power Requirement (W) 300"

many thanks

As I see, can't get over even 200 watts. Buy a 400 watts PSU, but a good one. Although I don't see a reason for system freeze if the PSU dies, you may have some problems with your processor or HDD. But, anyways, maybe your PSU can't give as many power as your system needs if we see that it's 8-10 years old. But you don't need a 500 watts PSU, as I said, 400 watts is fully enough, even if you want to upgrade the RAM or the VGA or add some HDDs.

Wattage isnt the thing that matters - its quality of the unit. Buy one from Seasonic, Corsair, Antec, PC power and cooling.

This would be a good option: Corsair Builder Series CX430 V2 430W ATX (80PLUS) Power Supply $19.99

Edit: and honestly your system would run fine on 300w - 400w gives you plenty of headroom. When card makers advise 300w, they mean for the whole system -not for just the card.
