Ups and psu requirement

[pavan_85]

Hello,everyone ...im new to this forum ,im having a hard time in deciding the ups and psu required for my system..i already have a ups and a psu but, dont know whether that is sufficient!!
specs:core i7 3770k 3.5ghz
mobo:asus p8h77-m
gpu:amd 7970 shappire dual x 3gb
hdd:1tb seagate 7200rpm
sony dvd writer 24x
ram 8gb crosair veangence
cabinet:haf combat with 6 fans
psu cooler master thunder 700watts(planning to get crosair ax850)
ups:apc 1100va/660watt
1:whether the psu is sufficient or should i get the 850 watt psu as mentioned above?
2:whether the ups is holding for 700 watts,will it hold for 850 watts? (atleast to turn off all the programs and shut down fast)
note:had this rig for two days played every game at ultra ,used it heavily untill my motherboard gave away(replaced it and got a new one now ,did not install yet; waiting for the suggestions from this forum.... had heard many good things about this forum) whether this had something to do with my psu or ups?

A PSU does not always make its rated wattage, it just creates what the system needs. I would estimate yor system would use under 450w at full load.

As for the UPS you would look up how long it would run from the published runtime chart. For the APC PRO 100VA the runtime for 450w load is ablout 10 minutes.

So you see there's no need to upgrade either PSU or UPS unless you want to.

are you sure it is only 450 at full load?
