Can Corsair VX-450W handle 200W TDP GPU

I presently have a corsair vx450w PSU and Numeric Digital 1000 Plus-V UPS. I am thinking of buying a high-end GPU like maxwell 980/970 after sometime. News on the net indicate a 180W TDP (at max 200 TDP) for 980 requiring TWO 6-Pin connectors. I am from Trivandrum, no good shops here which sell high-end components. So I will have to resort to online for purchase. Plz answer the following queries:

1) Will my PSU be able to handle 980. My PSU only has ONE 6-Pin, I will have to resort to molex-PCIE adapters.

2)If I need to upgrade my PSU I would like to go for Seasonic 620W Power Supply (S12II-620) which seems to be the most suggested PSU here on this forum. Plz confirm this is the correct model Seasonic 620W Power Supply (S12II-620) price in india Rs.5505. Buy Seasonic 620W Power Supply (S12II-620) online : Theitdepot.com . I would really appreciate if you can post direct purchase links from trusted online sources.

3)If I take the above 620W PSU will my UPS be compatible. It is a 1kV+ UPS. I would rather not buy a new UPS.

I know that my config will bottleneck GPU but most probably I will go for a complete upgrade next year.
My config: AMD 965BE + 6 GB RAM + 1TB HDD + 128GB SSD + Hyper 212+ 785g Mobo(Do CPU coolers take extra power than stock ones)

^ u did probably get an estimate of 650-700W psu. that that is what is recommend, 600-650W for a 200W card, assuming u will not be doing any OC.

look for something with 45-50A supply on 12 V rail.

I think VX450 can support both 970 & 980 Power requirement wise. But you need use Auxiliary power cables to provide power for the 2nd 6 pin slot.

Will my ups support a 600w PSU.

its not about supporting, the config u r saying (125w cpu + 200w gpu) will max consume no more than 400w.

but u need to choose psu such that, the load on psu is never more than 60-70% of its max capability, neither the normal load any less than 10-20%.

also, note that, with time, performance of psu goes down - read capacitor aging.

if u get 620w, then it will be ok, the load wont cross 400w, unless u do some extraordinary.

400W wont sweat a VX450 by any means. Its rated as 450W but can deliver upto 550W without a hiccup. Read its reviews. Corsair heavily undervalues the PSU Capacities.

I already have a molex to pcie adapter which I used for my old gtx 560 card. Yes I too read a few reviews when I bought 450vx stating it is an underrated 550w psu. I am using this since 3 years+.

Get seasonic s12ii 620. It is plenty. It is not good to use a high end gpu like 980 with a 450w psu especially an old one as the combined 12v o/p(power hungry components demands 12v) on 450w will be around 400w(most gives 360w only)and considering capacitor aging,get a new psu.
