I have 2 Desktop PCs that need protection nya plan nako mopalit og 1000VA nga UPS pero nag search ko sa net about this nya mao ni akong nakit-an
So akong gitan-aw akong PSU, then nakabutang Voltage is 220V and Current is 3A. So based sa3.3 Determining How Much Equipment You Can Connect to Your UPS
1. Make a list of all equipment that requires protection.
2. Each piece of equipment has voltage and current (VA) ratings printed on
the back label (see examples below). Your equipment may have a voltage
rating such as 88-264V. Since the standard voltage in the United States is
120V, you should use 120V in your calculations.
ViewSonic G810
120V 2.7A
50 / 60 Hz
Computer
Pentium Pro 200MHz
120V 2.0A
50/60 Hz
3. Multiply the voltage and current of each piece of equipment (VA
requirements); for example, 120V x 2.7A = 324VA, 120V x 2.0A = 240VA.
Add up the VA requirements for each device; for example, 324VA +240VA = 564VA.
4. Make sure that your UPS has at least as much VA capacity as your
equipment requires.
calculations 220V x 3A = 660VA is needed just for the PC only wala pa labot ang monitor
Okay ra ang wala labot ang monitor basta ang PC ma protectionan lang kay para sa ako work
man gud. Pero 220V x 3A = 660VA x 2 PCs = 1320VA!!! waaaaaaa... sakto ba na?

ayaw nalang i compute2x hehe.. tan awa nalang pila ka watts imo PSU aron mas dali

ang wattage nga naka suwat sa imo PSU kai iya na max power output niya padung sa mga components sud sa CPU
example: kung 600watts imo PSU.. naa posibility nga wala ka abot 600watts imo power usage sa imo CPU
ok raman tingali 2 CPU mag share sa imo 1000VA nga UPS ang problema lang kai mo gamay ang time ma hatag nga power sa imo CPUs kung mag brown out kung ma overload siya gamay

For 1000VA.. assume its capable of 500watts. Originally Posted by zhrike

if the sum of both exceed 500watt then kulang imong UPS.
Big factor here is the videocard nimo...

I suggest buying 2 650VA UPS, kaysa imo ipaslak ang duha nimo ka CPU ngadto sa usa ka 1000VA UPS. Mas dilikado nuon nga mag low voltage ang imong mga pc ana.
