What PSU to choose

Waffle404 · Nov 5, 2013

Ok so I have the following parts and I don't want to spend too much on my PSU:

1)CPU: I5 3570 @3.50 Ghz
2)GPU: EVGA GTX 660
3)RAM: 2X GB 1600 MHZ
4)CASE: BitFenix Raider
5)HDD: 1TB Seagate Barracuda
6)MOTHERBOARD: I haven't chosen one yet so if you could suggest one that would be great (Micro ATX or normal ATX)

So which PSU do you guys suggest that will be compatible with my case?
Not planning to OC or anything

I would say about a 600 to 650 watt. To be safe.

I don't think I can buy an American PSU because of the different voltage and plug etc..., and about the motherboard for the same price I could get an Asus P8Z77 V LK.
For the PSU i'm using a Cooler Master 500W GX Lite 86% energy efficent... would that be enough to power this pc?

That PSU is bad. Cooler Master lied about the efficiency, otherwise it would have the 80+ Bronze certification of power efficiency. Trust me, a cheap "high power" PSU is seriously not ideal. If you can tell me where you live, maybe I can find you a good PSU.

For a system using a single GeForce GTX 660 (non-Ti) graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

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

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum 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 being attempted.

In Italy; but all I need for my pc build is just above 300W... wouldn't that satisfy it?

I don't plan on overclocking, but if you say that the gtx 660 needs 450W which PSU do u suggest <$80

What about Xion AXP-700K14XE? It's cheap and 700W 80 plus bronze.

Xion make poor PSUs. The one I suggested can be found on Amazon Italia -
