A 350-400W unit is sufficient.

The monitor isn't powered from the PSU.

Can you tell me where you buying from so I can make a more specific recommendation?

PSUs may have passive or active power factor correction (PFC). Your APC unit will not work with an active PFC power supply, so be careful when you buy.

Good catch. I don't know anything about UPSes.

Active PFC is the norm (80Plus rating requires it) so decent units lacking it are a bit harder to find. I would suggest Antec VP450W, it's passive but still decent quality and quite efficient. Cooler Master Extreme Power Plus units are OK as well, but usually Antec VP is less expensive.

How do you know that without knowing which APC UPS he has? I have no problems with my SUA-750's or SUA-1000's and active PFC.

And we also use active PFC power supplies with old Back-UPS units at work without any issues.

If the UPS supports Active PFC units, get the CX 430. If not, get the Extreme Power Plus 460W.

 

[tanmoy saha]

how will i know ,my UPS will support it or not ?

Based on some quick research, an active PFC unit requires a UPS that can generate a pure sine wave, and those are very expensive. Your UPS is cheap and will most likely not support active PFC PSUs. Just get the Extreme Power.

Extreme Powers are alright except when they're stressed near their rated wattage, but (1) your PC doesn't consume that much power and (2) your UPS is limited to 360W output anyway.
