A computer power supply does not pose a seriously complex load ('complex load' in its electrical meaning); in other words, a computer power supply wattage (e.g. 550W) will be approximately the same as is VA value.However, a computer's power supply is typically rated after its nominal output power. Since it can't operate at 100% efficiency, the input power will be higher than 550W under maximum load.The power supply's technical data should tell you its rate of efficiency or its input power under maximum load, and you can chose the UPS accordingly.You could also chose a less scientific approach and justify the purchase of the 800VA, the 600VA, or even 400VA UPS: The bigger UPS will be overrated for this particular power supply, but might provided the better investment as it can support additional (small) devices and is likely to be sufficient in the event of a computer replacement (which might have different power requirements).However, the 600VA unit will probably be just fine for this particular case.You could also argue that the 550W power supply is a nominal power rating; it is the power the power supply is specified to sustain under full load. Your computer will very rarely come anywhere near this, and you could argue that high power number-crunching or DVD writing may not be required during a general power outage, making a less expensive apparently underrated UPS sufficient to sustain operations or data for the expected duration of a general outage.
my system is a motherboard: crosshair iii formula processor: 955 deneb black edition 3.21 ghz video card: pny - xlr8 nvidia geforce 9800 gtx+ 512mb memory: 2x 1tb wd caviar black ram: 2x 2gig g.skill ram ram takes like 5 volts each stick i think i was wondering because i want to add another video card and run them both but i need to know how much power im using and will it support another one on my current 550w powersupply?
GTX 260 should be better than GTS 250. GTX 260 requires a high end power supply whereas the GTS 250 will even work on a lower end PSU(at least 500w) because it ships with a six to 4pin adapter. For a single GTX 260 you will need atleast a rated 550W or 650W power supply like a corsair TX650 to power it in case you hv a high end processor as well. But the GTS 250 is a good option for those not wanting to invest in other comoponents as well but want a mid-high end GPU... But the GTX 260 SP 216 destroys all games....just dont let the other components in the system bottleneck it. the gts 250 1 gig can handle every game on the market also, as long as you dont allow other components to slow it down.
Assembling is always a better option. Its costs you less than getting a pre-assembled, plus you can get parts as per your requirements. Its not that difficult to build a pc in Indai. I'm also from same country, and I managed to get all the parts easily. You have many website where you can order parts. As for the cost of this build you mentioned, An i7-7700K costs around 30k or you can get 6700(non-k) for 24k 16gb ram would be around 8-9k Motherboard: if you want OC capability then you will need a z170 or z270 motherboard which starts from around 9-10k If you go for non-k cpu then you buy h110 or h170 boards which are available at less price (6–8k for a good quality one) Nxt is psu which would be around 5-6k for 550w which is sufficient i think For graphic card, FirePro is intended for with things like CAD, etc. And its cost starts from 10k can go high up till 3L (look for something in range of 20-30k) If you just want it for gaming ourpose then go for rx480 8gb or gtx 1060 6gb which comes in range of 20-25k, my personal favourite is MSI rx480 gaming x which costs 16.5k (4gb version) and 20-21k for 8gb version on amazon If you buy a K cpu then you will need a cooler for it which will cost additional 8-10k for a good quality one. Overall cost : 85-90k atleast for OCable PC60-70k if you go for non-OC one. Note: it can be cheaper, depending on what parts you select like air cooler vs liquid cooler, different brands of MoBo and other parts If you need any help then message me and I can give you suggestions based on your requirements and budget Edit1: you can also buy latest amd processor which will be available from march 2, they have performance equivalent to intel’s i7 range and cost is similar too. Only thing is whether they come with a stock cooler or not
